Audi A8 airbag use guide

Audi A8 car airbags as a standard configuration. For this system fault repair, need to master the structure of the system, working principle, and the Auto Diagnostic Tool correct test method. Here combined with the specific failure systematically to introduce.

1, Audi A8 airbag system structure and function
Audi A8 uses a multi point electronic sensor type airbag system, mainly composed of the following parts: control unit, side impact sensor, airbag, contact unit and safety belt tensioning device, etc.

Control unit, which includes 1 electronic acceleration receivers (i.e., frontal impact sensor), microprocessor, 1 mechanical acceleration receivers (for insurance), diagnostic systems (with memory), 1 accumulator and 1 crash recorder. The main function of the control unit is to receive the signal of the collision sensor, safety belt switch, monitor the status of the implementation of the system, the final issued instructions to the detonation of the airbag, the engine stopped working, connected to the alarm switch and lights up the fault lamp, and has self check, system monitoring and storage of fault information, crash records and other functions.

2, testing methods and precautions during maintenance
Audi A8 sedans airbag system has self-check function; Every time in the car when the system will detect the introspection; Once the system has a fault is detected, the instrument of red AIR BAG light will be bright. If the indicator light does not shine on when the ignition switch is turned on, or when the light is on, the system is in trouble, the system is in trouble. Fault diagnosis of the system can only be diagnosed by V.A.G1551, A. G1552 V., AS5051 V or other Launch X431 PAD or Launch X431 GDS diagnostic apparatus.

In addition, the system and the Audi car other electronic control systems, by using a dedicated Autel MaxiDas DS708 or Autel Maxidiag Elite MD702 diagnostic instrument that can be queried, troubleshooting part number and system software version of its system, the implementation of the final element, clear DTCs, read data blocks and coding and other functions to the control unit, the system's address code is 15.

No matter what kind of car airbag, it is only as a safety device, and can not put it as an absolute guarantee of adult life. So, in daily driving, we must pay more attention to the safety of driving, be sure to use the safety belt device.

8 signs indicated that the car will fail

Now more and more people have cars, but very few people understand the car, many owners fear the car suddenly go wrong, but do not know how to use OBD Diagnostic Tool to detect car. Then the car suddenly go wrong before What are the signs? Summed up the car before the failure of eight abnormal symptom.

1, the working conditions mutation
The working condition of car suddenly appear abnormal phenomenon, it is easier to detect fault symptom. For example: engine stalling and start is difficult, can't even start; Engine on the road suddenly drops, driving weakness; The road suddenly brake failure or wandering, or even failure, etc.

2, abnormal sound
Cars appeared abnormal sound in the process of moving, a car failure "alarm", the driver should immediately stop using the Launch X431 PAD or Launch X431 Cresetter tool to check. Especially the chassis, engine, suspension system abnormal sound coming from the most important.

3, exhaust abnormal color
When the engine work, exhaust smoke should be obvious. If you exhaust the other colors appear, it may be the engine abnormal, such as incomplete combustion exhaust was black, oil water blending in tail gas of a white, burning oil exhaust was blue.

4, oil spills
Leakage refers to the phenomenon of oil leakage in the fuel, oil, brake fluid, etc.. It is also obvious symptoms of failure, careful observation can be found. The car was removed after a period of time, there will be a piece of oil on the ground.

5, overheating
Usually it occurs in the engine, transmission, differential and brakes assembly. For example, engine overheating, mostly for the cooling system has a problem, is the lack of coolant or the pump does not work; transmission overheating, mostly due to lack of lubricants; brake overheating, brake shoes, mostly caused not return. The above phenomenon sometimes dashboard warning lights reflected directly, when the driver needs to drive observe.

6, inexplicably increased fuel consumption
Fuel and oil consumption is too high, indicating that the engine fails, we need to check service as soon as possible.

7, strange odor
Cars In operation, if the brake dragging clutch slip fault, will emit a friction plate of burnt; engine overheating, lubricating oil blow-by combustion, it will emit a special smell; a short circuit, grounding there will be a coke burnt smell the wire burned.

8, the appearance of abnormal posture
Cars parked on a flat site, use Autel MaxiScan JP701 or XTOOL VAG401 tool check appearance condition, if any horizontal or vertical skew phenomenon, namely abnormal appearance. Cause is that the frame, body, suspension, tires or other failures, which would cause instability when traveling direction, wandering, weight transfer fault.

How to maintain your car sunroof

Car sunroof is a very common configuration comfort. So the question is, did you use Auto Diagnostic Tool maintenance skylight? Here we come to the maintenance of the skylight and note to do a simple introduction.

One. Skylights use a long time, at its rails, the gap will be deposited in a lot of sand or foreign objects, such as occasional clean-up, will wear the sunroof member. It should be cleaned regularly lubricated around and avoid sand deposition, to extend the service life of the sunroof seals. Generally every six months, to use gauze or cotton dipped in water to wash the sealing tape or slide, rub after a little grease can be applied. Can be used for a fine talc, can prolong the service life of the sealing ring.

Two. Use skylights biggest concern is leaking, proper use and maintenance of skylights can effectively avoid leakage. Before entering the rainy season, in addition to clean up slide, seal gap is the foreign body, but also a harness protector or talcum powder sprayed on the seals and other components.

Three. Before turning on the skylights, should pay attention to whether the roof has obstacles to the operation of the glass panel. Sunroof panel design has isolated the heat and ultraviolet function, please use a soft cloth and cleaning agent cleaning, never sticky or have corrosive cleaning agent, you can also use Launch X431 V+ Pro3 or Launch X431 V Pro tools to detect the sunroof.

Four. On the very bumpy road best not to completely open the sunroof, otherwise may have skylights and slide rail vibration between related parts deformation caused by the too big to even make the motor damage. In addition, rain or cleaning vehicle when it is forbidden to open sunroof.

Skylight is not just a piece of glass so simple, its structure is quite complex, once skylight some failures,  using Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool maintenance and replacement costs is too high, panoramic sunroof maintenance costs even higher. Therefore, the maintenance of skylights not be ignored.

The same car, why fuel consumption high when you drive

Some car owners may very strange, the same a car, even for the same car, let others open, fuel consumption fell by half! Why do you have a higher fuel consumption than others?

1, bad habits: rapid acceleration
Personal driving habits have a relatively large impact on gasoline consumption, due to the mechanical design of a variety of styles, you need to run for a period of time will enter a relatively good state. During start-up, hard acceleration, braking and sometimes a good opportunity to reflect performance of the car. Driving this surge will make your fuel consumption, by OBD Diagnostic Tool test data show, it is 2-3 times the normal driving! Best driving speed is preferably maintained at 60-80km / h. And observe the road conditions in advance, it can be done with the throttle control for speed!

2, traffic reasons
This may not have much relationship and driving, but also fuel efficient route choices very important part, sometimes from far away, in the choice of route, try to choose not congested routes, from as short as possible! Only in this way can save more gasoline!

3, trunk mat put too much items
Vehicles carrying too heavy items, will make the fuel consumption is higher than the normal driving fuel consumption of about 2%! It may not seem like a lot, with a long time Many a little make a mickle., so many items, the count is not a small sum of money. So don't put things in the car!

4, pay attention to tire pressure
Some car owners may think that hot summer weather, the tire will Rezhanglengsu, so slightly deflating the tires! Suitable tire pressure for fuel consumption and life of tire is very meaningful! Through the Launch X431 IV GX4 Master or Launch X431 V Pro tool test, as long as there is a tire less hit 40Kpa of gas, the life of the tire is reduced by 10000 kilometers, an increase of 3%! If the tire pressure is reduced by 30%, to 40km/h to calculate the words, the fuel consumption will increase by 5%-10%! Therefore, adjust the tire pressure is more important for fuel-efficient terms!

5, engine technology
When buying a car should be aware that some young owners obsessed with appearance of the car, ignoring the fuel consumption and other factors, recommendations in the car before first practical Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect the car engine, engine technology for fuel-efficient advantage whether performance excellence. This is also very important!

What are the functions of the automobile skylight

In the morning to open a automobile skylight: release of harmful gases
Car after a period of time of airtight, after Auto Diagnostic Tool detection, air filled with more benzene, formaldehyde and other harmful chemicals. The first thing in the morning on the car, that is, open the sunroof, the use of negative pressure ventilation principle, rapidly clearing the car of harmful gases.

Open sunroof traffic jam: prevent exhaust into the car
When traffic jams, all vehicles are at a standstill, automobile exhaust will inevitably spread in the surrounding air. Then open the sunroof, and close the side, the car's gas will soon be discharged, and then the outside air into the car through the air conditioning filter out large amounts of harmful substances.

After exposure to open sunroof: to quickly lower the temperature inside the vehicle
In the hot summer, the car after sun exposure, the interior temperature becomes higher than the outside, then into the car will be very uncomfortable. After Launch X431 PAD or Launch X431 GDS tool test data show, in order to quickly lower the temperature inside the vehicle, an effective method is to open air-conditioning at the same time open the sunroof, in the heat discharge and air conditioning refrigeration effect after began to emerge, the skylight close again.

High-speed driving to open sunroof: reduce wind noise
When you open the side windows high-speed driving, the owner often be annoying noise and he could feel the strong winds plagued also affect driving safety. If you then open the sunroof, close the side, which can effectively prevent this from happening.

Cold Weather open sunroof: Quickly eliminate car mist
Use skylights defogging defogging is a quick way. Especially in the summer and fall, rain, humidity. Alice ventilation position only need to open the sun roof to the rear, the front windshield can easily eliminate fog, ensure traffic safety, when necessary, require the use of Xtool PS2 or AUTOBOSS V30 Elite tools to detect car performance.

Replace the automobile ATF fluid matters needing attention

Due to the popularity of cars, so many people will be familiar to car maintenance, but some people are not very understanding, so the use of Auto Diagnostic Tool maintenance vehicles, for some small details do not in place.

Replace automatic gearbox transmission fluid, it is often said that ATF fluid. Most of the cars are highly sophisticated automatic transmission power transmission device, mostly controlled by computer, equipped with a lot of precision components: torque converter, a sun gear, a planetary gear and a complex and fine oil passages and, it is very sensitive to temperature changes and other pollutants. If there is no maintenance, automatic transmission will be difficult and other gear shift. And most of the automatic transmission failure is caused by the transmission fluid pollution.

In the replacement of transmission fluid will generally in hydraulic variable torque converter and transmission cooling pipe is provided with a residual, and the residual amount is more, even with the new then residues were old contamination. In this case the use of automatic transmission cleaning agent completely remove the old fluid, to ensure that no residual old transmission fluid, can completely replace the new transmission fluid.

Under normal circumstances, each driving 50,000 kilometers, it should be connected to the device and the car's power, and the use of the Launch X431 PAD or Launch X431 V+ Pro3 adapter to connect the device and the transmission cooling tube. Start the car and let the engine is running at idle, then add the automatic transmission cleaner, slam the brakes, in order to remove harmful substances, and one by one, replace all gear of the automatic transmission, and finally with the help of automatic transmission oil equipment comprehensive replacement.

If you want an automatic transmission protective agent is added, it is preferably added in the proportion of 5% of this, If it is used for a long time, then it is best to add some stop leakage, to prevent the aging of transmission seals can also achieve the purpose of preventing leakage.

So, for the transmission fluid is a small thing, which can be a lot of things to note, the owner replaced when we must pay more attention to, and need to use professional Autel Maxidiag Elite MD701 or XTOOL VAG401 tools to detect car.

Car sideslip need to timely maintenance

Rainy day driving, the vehicle sideslip possibility increases, in addition to good driving habits and skills, but also the brake and the state of the tire good is also the key to safe driving. Automobile brake system is the most dual vacuum assisted hydraulic brake. Brake fluid transfer braking force which has strong water absorption. If water into the brake fluid in the braking process, the high temperature friction will produce water vapor. The gas is compressible, the brake fluid is compressed, it will cause brake failure or even failure, so after a rainy day, the need to use the OBD Diagnostic Tool to check vehicle braking systems.

Solution: Some brake fluid absorption water more serious vehicle, in the brake fluid oil on the cover can see water droplets. So in the maintenance must use the Launch X431 PAD or Launch X431 V Pro tool to check the brake fluid, to ensure the life safety of occupants. Once found the car brake fluid suction serious, should be sent to the professional repair shop in addition to water.

Also, before the arrival of the rainy season, if the vehicle tire wear, tire wear, must be replaced. someone to reduce tire pressure every rainy season, the purpose is to make the friction between tire and ground area increases, thus increase the adhesion, actually just the opposite, it is easier to cause the tire skid, keep the normal tire pressure is very important, regular use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect automobile tire pressure.

Automotive parts maintenance the periodic table

Car maintenance cycle is every car person should understand knowledge, car maintenance cycle table covers the oil, four filters, consumables. Recently, many friends some questions related aspects of vehicle maintenance and periodic table of advice, consultation with these questions today some automobile maintenance industry experts regard and the knowledge learned are summarized as follows:

First, the oil and oil filter
Cycle: every six months to replace (or 5000 kilometers), the replacement of some way to go on the freeway, oil choose yellow "shell" brand.

Second, the air filter and spark plugs
The cleaning cycle: once every half a year, changed every 30000 km, usually platinum spark plugs can be durable 50,000 km.

Third, the fuel filter
Frequency: Annually replaced once (or 10,000 kilometers), can be determined according to the quality of gasoline.

Four, brake fluid
Cycle: every two years to replace, in order to avoid brake fluid absorbs moisture and corrosion of components.

Five, coolant
Period: check once half a year, to increase the coolant, and check the concentration, the need to add distilled water, it is forbidden to add water, otherwise the corrosion of water tank and components, liquid level height can't more than a full, water thermometer temperature higher than 90 degrees said must increase refrigerating fluid in a timely manner.

Sixth, the camshaft drive mechanism and the toothed belt tensioner
Cycle: changed every 80,000 km.

Seven, throttle
Cycle: cleaned once every six months (or underpowered station speed instability when cleaning). 1 year or 20,000 km Replace air filter once! Air filter replacement cycle for 5000-10000 km, gas filter can be 15000-20000 replacement.

How to prevent the engine temperature is too high in summer

Hot summer temperatures, the hot sun road car to withstand the ordeal, the engine temperature is too high is summer cars need to pay special attention to matters, prevent the engine temperature is too high to pay attention to the following four bogey.

A bogey: boil immediately when opening the lid, add water
Radiator in the inland waters after boiling, internal pressure to a certain extent, if at this point immediately open the radiator filler, from hot water can, causing burns. The right thing to do is to find the tank water boiled, immediately opened the hood to increase air flow, when the water temperature drop is no longer a boil, then use a wet towel to do hand pad, radiator water cover unscrewed a first block and release of water vapor, a moment is opened entirely. To avoid water mouth above will face at the same time, to prevent scalding hot water overflowing face.

Second, avoid: boil after flameout immediately
Some drivers found after boiling, thought is immediately shut down. Want to know: Engine why boil is due to high temperature of inner water jacket is jacketed tank, wall, cylinder head temperature too high. At this time if the flameout, parts are in expansion in the state, with the gap is very small, after the shutdown will result in some soft metal off, and some will even cause sticking cylinder. So that after boiling, don't immediately turn off, should remain idle.

Three bogey: when the engine temperature is too high, pour cold water poured engine
Car launch forget to add cooling water temperature has been found to be too high, so he to the engine block, cylinder head and poured cold water to cool. Little do they know the consequences are serious, may cause the engine block because the quenching burst, causing irreparable consequences. Engine temperature will overshoot bad head gasket, burn Bush, machinery accidents; temperature is too high, causing the intake air drops, power is reduced; the tank boil, boiling coolant evaporation overflow; Launch X431 CResetter II or Launch Creader VII tool test showed that the engine will meet the various components gap decreases, increased wear and reduce engine life.

Four bogey: bogey water tire cooling when the temperature is too high
When the tire temperature is high, are due to the installation is not accurate, the speed is too fast and other reasons, but also the hot natural climate caused by. If in tire temperature is high throw cold water is bound to cause fetal internal structure due to sudden changes, resulting in the deformation matrix inside each ply between a, cause early damage to the tire, even the cord stripping. In addition, should also pay attention to the tire pressure and temperature, otherwise easy to explode accident. Once burst, light affects the speed; that will have a serious accident. During the rest of the journey, check the tire temperature and pressure in time. If it is found that the tire temperature, tire pressure is too high, can not take deflation and pour cold water on the way, should choose the shade, parking, the tire temperature, pressure drop of natural; such as wading, should be tire temperature decreasing after wading to prevent tire early damage.

Hot summer temperatures, in order to prevent the engine temperature is too high, it should pay attention to the following points: 1 plus sufficient cooling water; 2. Autel MaxiSys Mini MS905 or Autel MaxiDas DS708 tool to check the thermostat is normal. 3. driving in the instructions and pay attention to water temperature readings, requires no more than 95 ℃. 4. In exceptional circumstances, in order to strengthen the cooling air convection, can lift the hood to facilitate ventilation.

Car over speed humps Tips

Cars over some speed humps, the normal speed through the speed humps, through OBD Diagnostic Tool detection show that it will damage to the vehicle, and ride comfort have influence, encountered deceleration zone how to through?

The effect of speed humps just as its name implies is to make the vehicle to slow down, even if the vehicle is not loose throttle or brakes, the vehicle up and down motion of the reason will be because certain rate weakened. Of course, the main role of the deceleration zone or let the driver subconsciously reduce vehicle speed by this section, the initiative allows the driver to pay attention to the road conditions ahead, generally in front of the school may be crossing or continue downhill.

1. Before experiencing the deceleration zone, the first driver's consciousness is closing the throttle and tap the brakes, and pay attention to road conditions ahead, and through the rear of the rearview mirror to observe road traffic conditions, if trailing behind the vehicles more, close the throttle to reduce speed must not to slam on the brakes. It is easy to cause behind the vehicle rear end collision, you can use Launch X431 GDS or Launch X431 IV GX4 Master tool detection of brake system.

2. For automatic transmission vehicles, as well as from the deceleration zone after a short distance, according to the vehicle damping performance and road driving conditions, the vehicle speed control at 30Km / h or less, but not too low. Although the lower rate turbulence weaker sense, but it will affect the overall rate of road traffic. Vehicle speed control to a certain speed, the rear wheels begin to spin down when the band can throttle speed.

3. For manual transmission car with a manual transmission car is relatively complicated. Before entering the deceleration zone when some began to collect the oil from the deceleration and observed the traffic situation around the vehicle, and based on the vehicle speed sequential shift into low, generally 1, 2 block can be relatively stable through the deceleration zone.

In the vehicle rate below 30Km/h or lower through the deceleration zone, according to the Autel MaxiSys MS908 or Autel Maxidiag Elite MD701 detection. To a file through the deceleration zone, light step on the clutch to do linkage and throttle idle speed, the rear wheel through deceleration zone, observe the road in front, slowly lift the clutch and lightly on the accelerator, according to the speed or engine speed a step on the clutch shift into high gear. At last, the car speeds of up to normal driving state.

Car burning oil reason and solutions

The engine is the heart of the vehicle must be protected. The quality of the oil not only can reduce engine wear, increase engine efficiency, by OBD Diagnostic Tool to detect, but also to save fuel consumption, extended drain intervals and help keep the engine clean and prolong engine life, long-term performance of the engine as new.

There are three cases car burning oil
1, the valve seal leakage at the oil, because the poor quality of the valve seal, or the engine temperature is high, or exhaust vent is blocked leading to the greater impact of the valve seal.

2, Crankshaft ventilation mechanism can not be filtered out of the oil, leading to oil is sucked into the inlet, the only use Launch X431 V Pro or Launch X431 Diagun III tools to detect oil filter components, to eliminate failures or improve efficiency.

3, From piston engine oil leakage, for this performance, throttle only exhaust side have the carbon deposition, but the most damage, the main reason is lack of the inferior quality or process precision of piston and piston ring, under the turbine, the piston ring of gas oil energy is larger, the destructive force of the piston ring of piston is bigger, more heavy oil burning.

Overall, the engine burning oil to avoid is the use of qualified and suitable lubricants, and changed regularly. But note that the different cars engine design, therefore, in view of the model in different countries, the cost of repair and repair after the effect of the difference is very big. Universal significance and practical advice is to use good oil and regularly replaced.

Some burning oil was designed to be, this is actually the main part of the current owners complaints: obviously the vehicle does not have any fault, but the oil consumption is particularly large. So for the engine easy to have a fever, usually to use the Autel MaxiDiag Elite MD802 or Autel MaxiSys Mini MS905 tool to check the work condition, the regular check the oil consumption is normal, etc..

How to effectively prevent the car rust oxidation

Tip 1: alert subtle small flaws
Car paint surface often corroded, in addition to the common collision, scratching, driving tires up small stones to play in the paint, make the emergence of dots of a peeling paint, a long time will produce a small rust. And these small scars because most of the small, easy to be ignored. Therefore, usually to regularly use the Auto Diagnostic Tool inspection car, bonnet and body around, once found to promptly to the professional beauty shop for processing.

Tip 2: ground investigation easy to water at humidity
Vehicles traveling on the way, passing through muddy puddles, and some gaps at the underbody and interior floors, etc. are easy to accumulate sludge, such as the owner does not promptly cleaned, which makes cars rust. Thus, for doors, trunk bottom corner of the door frame of the key hole and the wipers moving parts, etc., should always use the Launch X431 V+ Pro3 or Launch X431 IV GX4 Master tool to check, while maintaining the smooth flow of the doors and body departments drainage holes, check the car cover Humidity matter , such as carpets, floor parts to prevent rust.

Tip 3: the soft paint do seal glair
Some paint softer vehicle traveling at high speed during the sand particles hit the car body may also result in a fine relying marks. For this kind of cars, glaze to body, it can form a mesh of solid protective film, improve the surface hardness, the effect can be stay for about a year. And the coating can also achieve a similar effect. Also for the bottom of the vehicle can chassis armor or a plastic sealing, which can protect chassis acid rain, corrosion protection, the original protective layer is not easy to dry and fall off, can also prevent the driving small stones the impact of the chassis.

Tip 4: Toothpaste can be temporary anti-rust coating
To deal with ordinary toothpaste. When found a new small scars, and gently wipe the toothpaste applied circle scratches. Rain or after washing, apply it. This generally reduce scratch mark, you can simply play a role in isolation, to prevent rust, through Autel Maxidiag Elite MD701 or Autel Maxidiag Elite MD702 tools to detect no problem in the short time. Especially white paint, the effect is most obvious.

Auto cooling system maintenance tips

The most common fault of the automotive cooling system is making the car broken down, and the loss of water., With the loss of water as well as accelerating weakness fault. Checking the vehicles with the boil water tank, first you should to use the OBD Diagnostic tools to detect other related components properly, such as using the correct grade of fuel, oil, spark plugs, antifreeze and adjust ignition timing and idle air-fuel ratio. And further check the cooling system under the normal circumstances.

Daily checking for the cooling system
First look at the water tank. Under normal circumstances, the tank will keep a consistent temperature when driving, if half cold or hot situation appears, you can determine the tank internal was blocked. You can connect the tank to the two kilograms of water pressure, reverse flush, if congested, you can use small amount of cleaning agent, taking care to clean the dirt tank and observe for leaks at the same time.

Second, look at the thermostat. Some people think that the removal of the thermostat can prevent the water temperature up to high, in fact, as long as the thermostat function properly and does not cause the water temperature too high, while the engine is running at low temperatures for a long time, it will be very harmful. In addition, many additional engine thermostat is a two-way action, when the thermostat is turned off, it will force to go small circulation of cooling water, while the thermostat is turned on, small loop will be closed, the cooling water will take the big loop at a whole. If you do not install the thermostat, because of the local resistance line throttling effect, the actual flow of a cycle is with very little water, but the water temperature rises.

Finally, using the Launch X431 GDS OR Launch X431 V Pro tool to check the pump. There are three ways for the damage of the pump: leakage, turn and throw impeller corrosion. The so-called revolution is lost pump shaft and impeller with too large gap, when the engine reaches a certain speed, the pump impeller can not reach the appropriate speed, resulting in poor water circulation. Cooling fan is the main component, and some cars have been eliminated fixed fan, and replaced with silicone oil electromagnetic and fan clutch. The characteristic is it basically does not work by a cold car fan, and the maximum amount of heat hot car; silicone fan clutch main fault is that oil spills, and the main fault of electromagnetic fan clutch is damaged water temperature switch, damaged line, and the damaged electromagnetic coil.

Cooling System Maintenance
1. Use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool check the cooling system seal, tightness of the fan belt, thermostat sensitivity and cooling water temperature, and keep plenty of cooling water.

2. Cleaning the cooling system, including the heat sink, the water jacket adhesion of scale, in order to prevent fouling in the cooling system thermal performance.

Summer car maintenance 6 small common sense

In many people think maintenance is to replace the three filters, oil and other consumables. In fact, during operation of the vehicle, many parts are constantly wear, routine maintenance, inspection range well beyond the three filters, oil, brake pads, spark plugs, a lot of places if you usually do not use Auto Diagnostic Tool inspection, maintenance, maybe there will be a failure. Here is a little common sense of car maintenance in the summer.

1, air conditioning use
Open air conditioning cycle. In the summer, the temperature is often high, so that the car is just starting to open the air conditioning, it should open all the windows 3-5 minutes, until hot and then drain off the air conditioning, it would play better results. If the engine is in a large load for a long time, it should temporarily turn off air conditioning. Refrigeration and air conditioning when the wind blows up the best, because the cold air to sink, the best choice for the wind blowing side gear block, adjust the air outlet up best. Finally, noting that the former first destination off the air conditioner to reduce odor generation.

2, body care
More rain in summer and autumn, rain acid rain, as well as strong sunlight, as well as the body fell to the surface of the gum can cause corrosion and oxidation of the paint. So to make a body from cleaning, polishing to waxing, sealing the glaze and a series of beauty care is necessary. Even if your body has paint coating, it is also take care about it, wash it.

3, tire pressure
For tyres must be using Launch X431 V Pro or Launch X431 PAD tools checked, If the pattern grinding to replace the new tires. Summer tire pressure inside rises as the temperature rises, often have a flat tire accidents while driving speeding, overloading or emergency brake is easy to cause a puncture. Therefore, due to lower tire pressure, or to improve physical properties of tire helium expansion to more stable.

4, the compressor and condenser
After stopping the refrigeration system, every two weeks to make the compressor work more than 10 minutes; To check belt tension periodically compressor; if found frozen oil leakage should be timely treatment; to regularly clean the condenser, to prevent oil, dirt and debris attached to the condenser heat sink.

5, wiper blade
Because many summer rain, automobile wiper frequency of use will be very high, therefore, to strengthen the inspection of the wiper blade is particularly important. In addition to regular inspections, but also pay attention to the cleaning wiper, wiper to prevent the accumulation of dust and impurities affect the wiper effect, or an adverse effect on the windshield before the car. Once the work results of the wiper blade is not ideal, it is necessary to replace the timely repair.

6, car sterilization
It is very important to do a good job in the work of disinfection of vehicles in spring and summer. Should always open the window ventilation, regular cleaning of car exterior and interior. When you wash, you can use a disinfectant scrub, if you have time you can use the Autel MaxiSys Pro MS908P or Autel MaxiSys Mini MS905 tool testing. However, we must pay attention to the air disinfection in the car is in the car no one. Disinfection is done, the need to open the window ventilation 5 ~ 6min, the facilities in the compartment with clear water, and then clean the cotton cloth to wipe, so as to remove the residual disinfectant.

Five major signs of tyre failure

When driving the tires have to withstand the pressure from the road surface. Tire wear occurs often does not mean your driving habits problems exist, but this kind of phenomenon but a normal driving inevitable fact, tire wear will gradually aging, and ultimately lose grip. If the vehicle during tire fails, the consequences would be disastrous. When you use Auto Diagnostic Tool to check his car tire whether is deformed or performance degradation of the situation, you can replace them with new tires and avoid failure. Here we will give five warning signal, tip you have the time to change the tire.

1. The tire tread depth
The thickness of the tread must be greater than 1.6 mm, if you often driving on slippery roads on low friction, it is best to ensure the tread thickness is twice the above values. You can purchase a meter to measure the thickness of the tread pattern.

2. tread wear indicator lines
The new tyres have more than one human nature design in the past: tread wear indicator. When the tire is very new or very low degree of wear, these indicator line hardly be found, but to reach a certain degree of wear of the tread these hidden ravine in the line indicated on the show out. Tread wear indicator line is flat rubber with tread longitudinal vertical embedded in the tread ravine. When you use the Launch X431 V+ Pro3 or Launch X431 Diagun III tool to check tire found one to two lines indicating the time, indicating that the tread thickness has been reduced a lot, in this case driving on slippery surfaces should be careful of. If almost all instruction lines are clearly visible on the tire, which means you need to replace the tires as soon as possible.

3. The tire sidewall cracks
The problems on the tyres are not all focused on the tread, and there will be some problems with the tire sidewall. By observing the tire sidewall to find those directly visible to the naked eye crack and cut. These tiny grooves on the tire indicates future cracks leak may occur, and worse even trigger a tyre blowout, the faulty tyres are we strongly want to avoid. So on the tire sidewall crack looks serious, or the cars to a garage as soon as possible replacement tires.

4. Bulge and blistering on tire
In some cases, the outer surface of the tire because of insufficient strength, resulting in higher than normal tire surface projections and foaming. If you failed to timely detection of the vehicle to the repair plant tire failure, intensity of tire surface area is likely to cause sudden burst, high-speed tire blowout even lead to ride under the personnel serious injuries.

5. Excessive vibration and jitter
Vehicle front row during a certain amount of jitter is inevitable, especially in the conditions of poor road conditions. When you already have some driving experience, you can judge for themselves what kind of feelings within reasonable limits of jitter and jitter illustrate how faulty vehicles. Many vehicle shake incentives may exist or the uneven tire axial displacement, it may be a shock absorber problem. But jitter may indicate some problems with the tire inside; even if the tires are not the root cause of the vehicle wobbled also damage the performance of the tire, causing the tire problem shortly afterwards. So if your car there are more serious jitter, jitter appear on the roads especially good roads, once the vehicle to the repair shop use Autel MaxiScan JP701 or XTOOL VAG401 tool check it. Always bear in mind, a greater degree of jitter is often a harbinger of vehicle breakdowns.

How to effectively prevent the car paint to be oxidized

All the parts on the car can buy the original factory, only the paint does not have replaceability. According to experts, due to oxidation, the new car will gradually darken paint, it will result in serious paint cracking or even fall off. Through OBD Diagnostic Tool testing showed that: absolute coating products can be a long time to maintain the original color, completely blocked pollutants.

Paint can not avoid the threat of oxidation and weathering, the impact of car paint oxidation once caused it is difficult to easily remove. Polishing, polishing method for removing the oxide layer, the paint will cause a lot of wear and tear. Therefore, conservation of new cars from the start, the regular use of Launch X431 GDS or Launch X431 CResetter II tools to detect. To prevent paint oxidation, weathering, it must be isolated from the outside environment --- paint to prevent oxidation, barrier evaporate. Absolutely coating products are the most effective means to protect the paint against erosion, can long maintain the original paint color. Coating absolute advantage is reflected in the following four points:

First, Absolute coating can be performed at the same time in the beauty of the function of protection, completely blocked against the asphalt, acid rain, gum, pollen and other pollutants, prevent paint oxidation.

Secondly, the absolute coating can paint the mirror effect, delicate texture, bright shine on people.

Third, the paint coating products absolutely no secondary damage, curing just do surface protection film purification treatment, no secondary damage to the paintwork.

Finally, Absolute coating of the warranty period of 2 years or more.

Summer car maintenance skills

Owners enjoy the car brings a variety of fun, and do not forget to do some of the necessary work, take good care of their car, regular use of Auto Diagnostic Tool to detect car, at the same time to avoid the failure of the car itself caused by traffic accidents, and put forward the following maintenance skills:

Protect the paint
Sun damage on the car paint, be sure to always wash and periodic waxing. If you want to do more thorough protection work, suggested a glaze or coating paint, paint to wear a protective clothing.

Check the brake
Under rainy wet pavement caused friction coefficient between the tire and the road surface is reduced, particularly at the tread has hydrocephalus, the lower the coefficient of friction, a sensitive braking system is particularly important, so one should always check the brake system.

Spontaneous Fire Prevention
Summer is the high incidence of spontaneous combustion vehicles, it is understood, driver's improper operation or car existence hidden danger is the main cause of car spontaneous combustion. Therefore to use the Launch X431 IV GX4 Master or Launch X431 V Pro tool check car oil electric circuit, found that aging line should be timely repairs, to prevent spontaneous combustion.

Using air conditioning
Into the car before you open the window ventilated, open the outer loop at the same time, to stay inside the heat discharge after open air conditioning, the cooling effect is better and faster. When the speed is less than 25 km/h, air conditioning should be placed in a lower gear, to prevent the occurrence of lack of electricity and air conditioning. Driving on rainy days, the window glass is fog, the influence line of sight, at this time as long as the direction of the wind will be dispatched to the windshield, open the compressor air conditioning, can be in a few seconds to achieve the purpose of effective mist.

Prevent evaporation
High summer temperatures, oil and water evaporation will increase, and therefore must take the fuel tank cap Gaiyan tubing to prevent oil leakage; always check the water level of the water tank, crankcase oil oil level, height, brake master cylinder within the brake fluid level and inside the battery electrolyte density and liquid level height, etc. Illegal, want to add and adjust in time.

Note that "freezing"
In the summer, some people think antifreeze irrelevant, can be replaced with plain tap water, in fact, this approach is wrong. Professional preparation of antifreeze is not only low temperature, high temperature characteristics are particularly good. When high-quality antifreeze approaching 200 ℃ in order to be "boiling." In addition, there are rust-proof antifreeze, cleaning effect. Therefore, the choice of the original antifreeze still summer, it can play a "sunstroke" role.

Prevent puncture
Summer surface temperature is higher, automobile tire using the environment even worse, so be sure to pay attention to doing a good job of inspection and maintenance of the automobile tire, regular use of Autel MaxiSys Pro MS908P or Autoboss V30 SPX tools to check the tire pressure, to prevent puncture.

How to determine the oil filter model

How to determine the type of oil filter? Intend to buy parts to repair shop replaced, but how to buy the oil filter model? And how to use Auto Diagnostic Tool to check the oil filter?

If you have a car maintenance manuals, go directly to view the contents of the maintenance manual, which will have mentioned. If you can not find the maintenance manual, must be carefully selected. Different models has a corresponding filter machine model, if you choose wrong, you can not successfully install, bought filter machine may be wasted.

Here you recommend a Launch X431 Creader VIII or Autel MaxiScan JP701 query tool, which has a self-maintenance functions of inquiry, as long as you put your car-related information can be input into the corresponding maintenance products out.

Oil tank filled full oil has four big taboo

Many owners like to say fill full when fill oil, usually come added to jump the gun, always want to continue oil into the tank, in order to scrape together a integer. Do you know? Through Auto Diagnostic Tool check data show that gas tank is too full can damage the car, and there are serious damage, there are four points of damage:

1, easy to cause fire
If you add too full of oil, oil is easy to overflow from the tank vent. A waste of gasoline, in case of spilled gasoline encounter fire, it is easy to fire, threatening the safety of life!

2, easily cause clogging of the vent
Once the vent plug, it will generate a negative pressure within the fuel tank, causing oil to poor, even for non-oiled. Car situation appears just after the addition was complete oil beat the fire engine, or a jump a jump phenomenon at high speeds, it is possible that due to the gas tank too full due.

3, canister constitute a hazard
Into the carbon canister is a liquid rather than a gas vapor, carbon canister would constitute a hazard. The canister is to reduce vehicle fuel tank, carburetor gasoline evaporation apparatus matter emissions. Through the Launch X431 V Pro or Launch X431 Diagun III tool check normal carbon tank should be above 50000 km, but after the immersion, immediately scrapped!

4, volatile gasoline easy carcinogenic
The activated carbon canister, generally near the outer circulation air inlet, when the oil is too full, canister saturation, pressure too high and pressure relief exhaust, containing gasoline constituents of air into the compartment, uncomfortable "gasoline" always around you. Oil and gas components have been confirmed to contain benzene and other carcinogens, if every time so that the car refueling, through Autel MaxiSys MS908 or Autel MaxiDas DS708 tool checks show will increase the risk of cancer.

How to correctly use car air conditioning

The correct use and maintenance will maximize the performance of air conditioning and extend the service life, and the error use will greatly damage the air conditioning systems, to make life greatly reduced. Automobile Air Conditioning life depends largely on whether the user is able to correctly use and maintenance. You can use the Auto Diagnostic Tool to check car air conditioning performance, air conditioning installed on the car must be carefully read the use of instructions, in accordance with the above instructions.

1, In order to avoid the excessive load of the engine starting, while the air conditioning compressor can quickly into the best working conditions, the first not to rush to the open air. Should put doors, windows open, you can use a fan for ventilation, etc. twenty or three minutes later to sit in the hot gas discharge start the car, and do not rush to close the windows, turn on air-conditioning outside the circle, when the inside and outside the temperature is close, and then close the window, enabling the internal cycle.

2. Select the appropriate air temperature, air conditioning maintenance is the first step. Because of the hot weather, many owners prefer to adjust the temperature too low, which will affect their health. Under normal circumstances, the compartment temperature difference with the outside temperature should be 5 ℃ to 6 ℃, the optimum temperature of air conditioning is 18 ℃ to 25 ℃.

3, Refrigeration and air conditioning wind best blowing up, because the cold air to the sink, the direction of the wind tests are best choice blow face gear, adjust the outlet up effect is best, don't choose the windshield of the block, because the temperature of the windshield is very high, would offset a large refrigeration effect. When selecting wind speed gears don't always use top gear, big air volume refrigeration effect is not good. If only the front occupants to choose 2 or 3 block wind speed is enough.

4, suggested that the owners to best in preparation for parking in front of the 6-7 minutes will close the air, let the remaining heat from the evaporation tank water drying, eliminate and outside temperature, so that you can easily keep air conditioning system relatively dry, can reduce air conditioning odor. Moreover, in front of the parking lot to close the air conditioning, will avoid the impact of the battery and air conditioning, to prevent damage to the engine.

Automotive air conditioning system in use process, the air will flow in the blower, refrigerating system evaporation tank, heating system of the small water tank and the air duct. As long as the air conditioning system blower or the air intake mode choice in the indoor cycle, regardless of whether the use of refrigeration devices, air will enter the system. Through Launch X-431 PAD or Launch X431 GDS tool to check show that the above device surface accumulation with a lot of dust, moisture, bacteria and other dirt, and will cause damage and allergic reactions to human respiratory system and skin, directly affect the occupant's health, and air-conditioning system itself will appear refrigeration effect is bad and a small amount of wind and other fault.

Under normal circumstances every 5,000 km or 3 months to conduct a clean air filter, every 20,000 km or 12 months use Xtool PS2 or Autoboss V30 SPX tool to check the air conditioning, and replace the air filter. This will ensure that you can enjoy the fresh clean car interior environment to ensure your health.

Timely attention to automotive air filter maintenance

Replace "three filter" according to the use of the car, maintenance and oil quality grade circumstances, automotive air filter equivalent to the human nose, the air entering the engine to go through the first hurdle, Filter the air through the blocking effect of filter paper. When the dust of the filter paper surface of the pores, it will cause blockage, which directly affect the car's engine, unimaginable consequences occur. Because the air filter and direct contact with the outside world, so it is easy to be blocked, through Auto Diagnostic Tool check found engine will accelerate the powerless and idle instability, and other symptoms, the normal work of the air filter can avoid premature engine wear and maintain the best working condition.

The density of the atmosphere contains three different basic particle contaminants that dust, debris and soot. Open highway dust content is low, but emissions from vehicles concentrated, so that the content of carbon particles in the air is significantly higher, and therefore frequently used Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the air filter. The dust concentration in the larger areas such as construction sites, sand area, air filter inspection and replacement frequency to be higher. Also now the majority of automotive air filter is made of paper, when the damp air filter, intake blocked, weak acceleration of the vehicle becomes more serious when the water is drawn into the interior of the engine into the cylinder, since water is incompressible, seriously damaged will cause the engine internal moving parts, engine even scrapped.

Few people noticed it, but auto parts Once the problem occurs, the result is the most serious threats to travel safety, not because these small parts and components affecting the active force of the car, so regular use Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool to check car engine working conditions.

Automatic transmission car maintenance knowledge

Automobile automatic transmission, manual and semi-automatic transmission car, three different types of operation of motor vehicle, automatic transmission car is easiest, many opened automatic transmission cars have awareness in this regard, therefore automatic transmission car compared with those of other two kinds of car electronic devices will be more, should pay attention to in the maintenance of more, also need to use professional Auto Diagnostic Tool repair, therefore, compared with the other two cars, vehicle with an automatic transmission is more difficult to maintenance, here to introduce some automatic-shift cars maintenance knowledge.

1. Always check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, check the engine oil in the cold state, and transmission oil is needed to oil preheated to about 50 ℃, then to block a rod in each block for 2 seconds in a stop block, the oil dipstick normal oil level should be between the highest and the lowest line, such as not enough, it is timely to add the same quality oil.

2. Correct replacement of transmission oil. Presently preferred method is dynamic change oil, cleaning equipment using a dedicated gearbox, in the gearbox during operation, the old oil full circle, emissions clean, add a new gearbox oil, so oil change rate is as high as 90%, to ensure good oil effect.

3. Master replacement of automatic transmission oil cycle. Automatic transmission internal control mechanism is very precise, with a small gap, so most manufacturers recommend automatic transmission oil change is usually two years or 40,000 to 60,000 km. During normal use, the transmission fluid temperature is generally around 120 degrees Celsius, so the quality of oil in demanding, must also be kept clean, as well as regular use Launch X431 V Pro or Launch X431 V+ Pro3 tools to detect. Secondly, gearbox oil to use after a long time will produce grease, it is possible to form sludge, will increase the friction plate and the parts wear, but also the influence of hydraulic system, make the power transfer is affected. Third, the dirty oil sludge will enable each valve body moving smoothly, hydraulic control affected, so that the automatic transmission abnormal.

Automatic transmission vehicle maintenance and repair in strict accordance with the maintenance manual to repair, encountered do not understand the situation, do not go to their private to deal with, go to a specialized repair shop or 4S shops to consult professional people, but the best maintenance method is usually the correct use of the car, regular use Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to check the car's overall situation.

Regular maintenance and check car handbrake

In the big city in the congestion of the car, the vehicle before and after the gap is basically less than one meter, and the slope of the overpass is very large, parking brake is particularly important. However, due to various reasons, the handbrake will appear when no use. In the daily inspection and maintenance of the vehicle, don't forget to use Auto Diagnostic Tool to check the performance of regular handbrake.

First, determine the operating position of the handbrake lever. Generally, when the handle is pulled three-quarters of the entire trip, the hand brake system should be in a normal brake position. Should first find out the work point, the general 5~7 case is normal position. Then check the brake mechanism efficiency, also is have a look handbrake to work effectively. The car drove up to the steep, good road conditions of the slope, step on the brake pedal, the neutral gear, pull the hand brake handle to just to determine the position of. Slowly loosen the brake pedal, if the car did not happen sliding, that means the hand brake performance is good.

Check the handbrake sensitivity, since it is very important to the slope. On flat roads slow driving, slowly pulling handbrake handle and feel the sensitivity and the junction of the handle. If it is found that the brake braking efficiency or sensitivity is not ideal, can regulate the handbrake thread through Launch X431 PAD or Launch X431 GDS tools to solve.

Adjust the hand brake wire. If found in the test the brake is not sensitive, can be solved by adjusting the handbrake arrows, below the hand brake handle with an adjustable compensation institution. Adjust the need to remove the handle decoration cover first, then use tools to adjust the length of stay, in order to ensure the hand brake is in the best working state.

Ordinary driving, the handbrake usage is very high, but the handbrake is not universal insurance, its performance will decline with the increase of using the number of times. Most of the time, because the system failure or improper use and don't effect, this is also the major hidden danger of the accident, so owners should regularly use the Autel Maxidiag Elite MD701 or Autel MaxiDiag Elite MD802 tools maintenance check handbrake.
