Car battery daily maintenance Considerations

The length of service life of the vehicle battery, on the one hand, depends on the structure and quality of the battery, on the other hand, it is closely related with the daily use of OBD Diagnostic Tool maintenance, so we should do the following:

1, note that securely installed and cleaning maintenance
First, the battery in the car on the installation to be firm and reliable, to prevent the vibration caused by the car in the driving caused by the loss of the internal electrode of the battery and the connection of the external wires. Second automobile starting batteries can bear a large current discharge time is short, but small current for a long time discharge will lead to reduce the battery life; so should often remove the dust on the battery, and posts and threads on the oxide and the liquid outlet overflow electrolyte, keep clean and dry, to prevent the battery self discharge.

2, pay attention to timely charge
When the battery voltage is insufficient and the light is dim, the starting weakness, should carry on the vehicle outside the supplementary charge promptly. Battery charge capacity can be reflected on the dashboard, you can also use the Launch X431 PAD or Launch X431 GDS tool to detect. When the ammeter pointer display when about a third, it should be promptly charged, charge more than two-thirds of the over-discharge. Overdischarge the charging current is comparatively large, is not conducive to reducing active substance. Cars traveling in cold regions, to avoid the battery is fully discharged, in order to avoid the electrolyte freezing.

3, regular inspection
a, check the battery housing for cracks and electrolyte leakage.

b, always check the battery cable is solid, all joint, must maintain good contact, prevent sparks, causing the battery to explode. For example, always check the battery in the holder fixing bolt tightening, often view the pole and wiring connector too is reliable; Do not insert metal objects on the battery to prevent short circuits; sealed plastic cracks to timely repair. Check the circuit of each part of the aging or short circuit.

c, regularly check the battery electrolyte density and liquid height, check the battery discharge level, to prevent over-discharge and early retirement.

d, to keep the battery charging circuit is normal, when the battery charge indicator does not necessarily excessive use of the correct display charging properly or not, you can use the following method: In the evening let the car idle state to keep open the car headlights, illuminated to a certain fixed position, eyes fixed on the center of the light closer look, then refuel anxious to see if the lights suddenly brighten, lighten describing a generator and charging circuit were normal, also can be directly used Autel MaxiSys Pro MS908P or XTOOL PS90 GDS tools to detect the battery state.

How to clean up automobile carburetors and fuel injectors

In the sandstorm weather, the vehicle will inevitably be covered with dust. The surface of the vehicle can be washed clean, but the car is the internal sand how to deal with it? Don't ignore the carburetor and fuel injection nozzle cleaning, the need for regular use Auto Diagnostic Tool to check car performance.

Generally the best put the car sent to the professional repair factory use Launch X431 PAD or Launch X431 IV GX4 Master tool inspection. first carburetor disintegration, the carburetor needle triangle and idle needle soaked in alcohol, mainly in order to remove carbon deposits; then carburetor cleaning agent with a special individual components, wipe clean assembled, with a wind blowing high-pressure air pump, the purpose is to detect patency carburetor, and finally installed carburetor, ignition adjustment.

To repair service station, required at the car after a sandstorm performance effect how, so service personnel according to the problem you provided, if the carburetor fuel mixture ratio is too thick, plug the oil coke, rear take the blue smoke, These faults are described piston ring wear ineffective.

For the clarity of the carburetor and fuel injection nozzle, mainly is to clean the idle valve and a filter screen, the cleaning should choose regular maintenance center, general street repair shop do not have these professional XTOOL PS90 GDS or Xtool PS2 equipment, just cleaning, simply not achieve any effect.

Auto Body jitter causes and solutions

Body slight jitter is the situation many owners often encountered. If the owners start the vehicle, if we find the body slightly shaking, then there is likely to mean that the vehicle under three kinds of condition:

If the driving car process, found the body there is a slight jitter or offsets, generally is a tire caused by failure. First may be tire balance condition, need the owner to do a four-wheel positioning and dynamic balance as soon as possible, if the vehicle is not running deviation do the tire dynamic balance, and then use the Auto Diagnostic Tool to check tire dynamic balance.

Another condition is more serious, may be because the steel ring caused by deformation, which requires owners to professional repair shop to check. This situation generally occurs in the use of a longer life of the vehicle body. General motors to replace the new tires, new rims must be used followed by the Launch X431 PAD or Launch X431 Creader VIII tool to check the tire balance, otherwise the weight average steering wheel is not easy to happen dithering phenomenon. Body jitter on driving comfort and manipulation of the judge will make a difference.

The third situation caused by shaft deformation imbalance, general this kind of situation in the chassis more car collision.

If there is a car body jitter, which is aimed at the vehicle equipped with manual transmission, the performance is: in the beginning and slowly lift the clutch pedal process, the vehicle has a jitter. This is due to a clutch three piece suit (flywheel, clutch plate and pressure plate) the irregular wear, in which one or a few pieces to produce deflection caused by, in the bonding process, clutch disc can not be smoothly joined, but a joint, a little and release of the engine power is just beginning to transfer, and suddenly slipped, the vehicle performance is similar jumps is feeling. Replace the damaged parts of the clutch in three pieces, and then use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the performance of the car.

The correct way of maintenance the car handbrake

In the process of using a car parking will certainly use the handbrake. Because the driver leaves the vehicle, if not with the hand brake, then the vehicle is likely to slide and may cause an accident. Sometimes, the handbrake has pulled up, but because the brake system failure resulting in the accident. So the majority of riders should be regularly on car brake maintenance and check for proper use of Auto Diagnostic Tool. Here we introduced under the normal maintenance of the handbrake.

Handbrake lever operating position is determined
Like with the foot brake pedal, handbrake handle also has a pull stroke. Typically, when pulling the handle 70% of the entire trip, the handbrake system should be in a normal braking position, so before check braking handbrake should first find out that 70% of the working point, this work can be done through to determine the number of ratchet sound. Cars can be parked in relatively quiet place, and slowly pull the handbrake, the number of clicks while pulling ratchet issued until the end of the handle pulled up. Then calculate 70% of the total sound position, this position is the effective operating point handbrake handle, if you want to save time friend, you can use the Launch X431 PAD or Launch X431 V Pro tool detected 70 percent of the work position.

Check the handbrake mechanism Effectiveness
The car drove into a larger slope of the ramp on the road in good condition, slam the brakes, in neutral (if the automatic transmission is hanging in the N block), will work to pull the handbrake lever position just determined. Then slowly release the brake pedal, if the car does not slip occurs, it shows the effectiveness of the handbrake is good. Uphill and downhill should be done once each.

Test sensitivity handbrake
In addition to the braking efficiency, should also check the sensitivity of the handbrake, this is particularly important for the initial slope. In the absence of the slope on the road to slow down, slowly pulling handbrake handle, the handle and the sensitivity to feel joint. This method will make the handbrake mechanism wear, so check the number should not be too much. In process inspection, if found unsatisfactory handbrake brake efficiency or sensitivity can usually be by adjusting the handbrake operation cable to solve. The hand brake handle and the bottom of the cable connection (generally by the interior cover) with a tunable compensation mechanism, with wrench, loosen the lock nut, you can stretch the brake cable length. Some auto adjusting mechanism is arranged at the bottom, if inconvenient adjustment should by professional maintenance personnel to deal with, can also use Autel MaxiSys Pro MS908P or Autel MaxiScan JP701 tools to deal with.

Summer high temperatures using car easy cause four big hidden trouble

Car paint accelerated aging
Solution method: Avoid direct sunlight washing the car, the car paint surface water droplets will produce convex lens principle, would lead to further aging car paint. Try to avoid parked in the parking lot of exposure, try to use car clothing and other materials to resist ultraviolet damage the car paint, try to paint the car waxing, sealing glaze, coating maintenance scheme, use Auto Diagnostic Tool testing cars, extend the life of the paint.

Heat easily puncture occurred
Many car owners should know that the tire pressure is too low actually tire burst a factor, but we know that the summer heat also lead to a cause of tire burst.

Solution method: Tire pressure is too high and too low are not safe, maintain normal manufacturer with tire pressure is beneficial to train operation safety. Standard tire pressure generally posted on the edge of the driver's door or the back of the cap.

Door seals easy to aging
Solution method: Sealing ring every other two quarters for a clean, dry with a clean damp sponge to wipe the dust on the slide rail, trench, reoccupy dry sponge mop wipe once more, to maintain the cleanness of seal ring. Can use the maintenance products such as table board wax on the depth of the door seal for maintenance, to prevent cracking. Can be used to Launch X431 PAD or Launch X431 GDS tools to measure performance.

Interior easy to aging
Solution method: One is the paste solar film. Good solar film in addition to cut off most of the ultraviolet ray, can also play a heat insulation effect; The second is when parking for car mount the sun block, this is to protect the automobile instrument desk, a good way to the front seat.

Other Considerations
Due to summer heat and sun exposure, high temperature inside the car, the owner don't put lighters, batteries, carbonated drinks in the car, prevent because of heat explosion caused by such accidents. Regularly use Autel MaxiSys Pro MS908P or Autel MaxiScan JP701 tools to detect cars. Hot summer weather, the driver pay attention to reasonable rest, after all, high temperature and muggy weather for driver is also a test, drive safely to keep in mind.

How to replace the fuel filter

Before trying to repair the car you have to always wear goggles, when necessary, still need to wear the PPE personal protective equipment, such as latex gloves or closed type shoes. Keep in mind that petrol is highly combustible, and when you are ready to deal with the fuel system to ensure that there is a fire extinguisher and Auto Diagnostic Tool, to prohibit smoking, to ensure that the fire away from the car or fuel tank, must be careful when working.

Steps:
1. To park the car on a solid plane.

2. Reduce pressure fuel system (fuel injection systems operate at very high pressure environment, the need to reduce pressure), follow these steps:
(A). Loosen the valve cover to reduce the fuel system pressure
(B). Remove the fuel pump relay or fuse (according to your owner's manual operation)

3. Start the engine until you run out of the pipeline gas engine stop.

4. To find the position of the fuel filter, which is generally below the engine or the fuel tank. If necessary, you can use the jack to lift the car, and from the fuel filter out of the oil pipeline.

Note: The old car carburetor, the oil pipe is hose with spring. The new injection type engine, the oil pipeline and the clip together, or the quick lock connector, require special Launch X431 PAD or Launch X431 V+ Pro3 tools to remove.

5. Remove the mounting bolts of the fuel filter, fuel filter can be removed then.

6. Compare whether the new fuel filter and removed type is consistent, confirmed after installing a new fuel filter, pay attention to ensure its leading to the engine, can filter retaining bolt installation confirmation.

7. connected to the pipeline and install the fuel pump fuse.

8. Re connecting the battery box, and you can lower the car after it is finished.

9. Start the engine and check for fuel leaks.

Note: Due to the lack of fuel, the engine may not start immediately, but with the fuel pressure increase the engine will start.

10. The actual driving cars, using Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check whether the engine is weak.

Audi A6 normal start up appear EPC light

A driving of about 68000 km of the audi A6 car. When the vehicle is normally started or driving, EPC light appears on the dashboard. You need to use the OBD Diagnostic Tool Check.

Use 5052 check, the engine fault code 05924, start the machine on the short circuit signal suppressor. As a navigation fault diagnosis, no results. Using the Launch X431 PAD or Launch X431 V Pro tool, it was found that when the clutch pedal is pressed lightly, the EPC lamp is extinguished, and thus can be judged, and the EPC lamp is on the clutch pedal switch. Access to ELSA, that this switch is F194 - for the start of the engine clutch pedal switch, the circuit diagram shows the F194 by J623 control, assuming the internal short-circuit F194, then do not have to set foot clutch pedal, you can start the engine. Results can start the engine. As the vehicle traveling in the engine control unit a direct clutch switch signal, the engine control unit will light the EPC lamp. Solution: replace F194.

This fault can be directly analyzed from the fault code, if you are not familiar with, you can use the Autel MaxiSys Pro MS908P or AUTOBOSS V30 Elite tool to check, the engine is controlled by the engine control unit, the engine control unit to receive the clutch switch signal to control the starting machine, so logic is easy to find fault.

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.

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.

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.

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.

Nano fuel additives basic knowledge

Nano fuel additive is a functional material to make up for the defects of the fuel in some properties and to give some new properties of fuel. It has washing, dispersion, emulsion breaking, antioxidant, promoting burning, corrosion, rust, lubrication, cleaning function. According to Auto Diagnostic Tool tests show that nano-saving device is mounted on the pipe of the car, after the installation of this equipment can purify exhaust gas by 50% -90%, 10% -30% fuel savings, enhance the power of 10% -30%, reduce engine noise, suppression coke production, clean combustion and prolong engine life.

Maintenance and good driving habits is the key to saving, The best fuel-efficient way is at ordinary times to use the Launch X431 PAD or Launch X431 GDS tools check vehicle, to develop good driving habits. Do not always emergency braking or hard acceleration. Energy-saving cars "four bogey." A bogey, since often require hard acceleration, braking, fuel consumption ratio will increase 2-3 times uniform; two bogey, pay attention to traffic conditions ahead, without prior dodge or slow down in advance, the car will see the red light or experience, rely on the emergency brakes, natural fuel soared; three bogey, high speed and low-speed operation, the engine idle for a long time; four bogey for a long time over economic speed driving.

Nano fuel additives Product features: can effectively protect the engine, it can increase the useful life of an automobile engine and some 5 - 10 years, based on Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool checks show can effectively fuel-efficient 5-16.6%, remove carbon deposition by more than 95%, the noise of the engine has also dropped. Nano fuel additive has a clean, dispersion, emulsion breaking and promote burning effect, after clear the carbon deposit in fuel oil, through the "microburst", promote burning, finally to reduce emissions, eliminate exhaust black smoke.

How to Clean EFI engine gasoline injection system

EFI engine is currently using a wide range of devices on the car, compared with the conventional carbureted fuel system, EFI engine fuel supply system, not only complex, but also parts with precision. When cleaning maintenance to must pay special attention to, when necessary also need to use Auto Diagnostic Tool to check the engine oil supply system.

During cleaning maintenance, some parts can not be disassembled and dismantled, some parts assembly requirements is high, which makes fuel injection system than carbureted gasoline vehicles are more vulnerable to gasoline in the glial, sediment hazards, resulting in clean work is very complicated.

Engine fuel supply system, into the exhaust system is clean, has a decisive influence on car driving performance and even. Due to the influence of driving environment and fuel quality, the injection nozzle, intake manifold into the exhaust valve and combustion chamber and other prone resin sediment, through the Launch X431 PAD or Launch X431 GDS tool inspection data show, affecting the normal fuel supply, caused by fuel injection quantity control are not allowed, atomization adverse, oil pressure regulator failure, resulting in engine idle speed instability, poor acceleration, knock, lack of fire, increased fuel consumption, exhaust emissions exceeding etc. fault phenomenon occurs.

In order to clean the oil supply system need to solve the problem from the inside, they usually avoid demolition clean way. Vehicle cleaning job by Xtool PS2 or Autoboss V30 SPX special equipment and cleaning agents, under certain pressure and flow control, intake manifold, fuel injectors, intake and exhaust valves and thoroughly clean the combustion chamber, in order to restore normal operation of the fuel system to ensure good driving performance of the car.

What is the octane improve agent

What is the octane improve agent? What does it do? Octane improver is to increase the octane rating of automotive additives, can be used OBD Diagnostic Tool to check out the car's octane, octane improve agent is a kind of common gasoline additives, which is popular in the additive products.

The most effective way to improve the engine efficiency is to improve the engine's compression ratio, but the compression ratio of an increase, knocking combustion significantly enhanced, higher-octane gasoline can reduce detonation, as the engine compression ratio continues to improve, This forced refineries to produce high-grade gasoline. Octane increase only to reduce engine knock, and reduce fuel consumption, thereby increasing the economic efficiency, Launch X431 V Pro or Launch X431 PAD tool inspection data show: Improve the gasoline octane number 1 unit, saving gasoline 1.3%.

For a long time, oil prices have been stubbornly high, bring the owners a little cost pressures, how to reduce the fuel consumption has been a concern. In addition to source fuel from outside, how can the existing fuel play to the best effect is also very important. Presumably this is the octane value improver where it! Improving fuel quality, to the full combustion, reducing fuel consumption.

Of course, as a gasoline additive, in the selection or according to the specific circumstances of their own car, everything from reality, the effect of the additive to play to the largest , you can use the Autel MaxiScan VAG405 or Autel MaxiDiag FR704 tool to check, it will prompt you to use what kind of gasoline additive.

The present is the most widely used vehicle hydraulic power steering system, then daily how proper use and maintenance vehicle hydraulic power steering pump do? when necessary, require the use of OBD Diagnostic Tool.

Generally, in normal use and maintenance hydraulic power steering pump, need to pay attention to the following aspects:

1. The hydraulic power steering pump when used to choose the correct type of booster oil, otherwise it will affect the power steering pump efficiency and service life. You can use the Launch X431 PAD or Launch X431 IV GX4 Master tool to check power steering pump.

2. Always check the use of booster oil, booster oil must be kept clean. Regular replacement of the booster oil, in filling booster oil must be equipped with the filter.

3. If a long time parked car when restarting, do not work immediately, at least 10 minutes should be no-load operation, booster oil and other fluids to be assisted to reach normal operating state and then driving.

4. operated vehicle steering pay attention to observe steering system is functioning properly, whether the impact or noise, booster oil passage for leakage, you can use Autel MaxiTPMS TS601 or Autel MaxiTPMS TS501 tools to check in order to detect and troubleshooting.

15 minutes to quickly remove the odor of automotive air conditioning

Automotive air conditioning after a very long time without use, open feel the smell blowing. Especially those moldy smell, so the driver feel uncomfortable. Some of driver go to 4S shop for cleaning the entire air conditioning system, duct. In fact, there are three kinds of effective methods of air conditioning in addition to smell, it is worth a try. Some methods require Auto Diagnostic Tool, you may wish to look at their own personal experience.

1. Replace the evaporator equipment, and manual cleaning air conditioning heating device at the bottom of the shell;

2. Clean the evaporator, to the air conditioning and heating device sprayed disinfectant on the bottom of the shell, eliminate the inside mold;

3. The first two approaches is slightly complicated, the third method is simpler, you can open the air-conditioning heat windshield maximum temperature, continuous opening 15 minutes, it will effectively remove the musty, mildew and odors.

Can go to the market to buy supplies automotive air conditioning cleaning agent or sterilization deodorant spray. Then, open the windows, start the engine, then closed the air conditioner AC block, open to the outer loop block, then the fan to maximum. In this case, find the external air inlet port of the vehicle, which is injected into the cleaning agents, cleaning agents on the wind, attached to the surface of the evaporator and evaporator will absorb dust and mold, then let the fan run another 15 minutes. Next, the cleaning agent will be discharged from the drain outside the vehicle, the whole operation takes about half an hour, then use Launch X431 Diagun III or Launch X431 PAD tool for detection.

Haze days increased air filter needs to be replaced twice

A wider range of haze invasion world, more and more people are used to go out wearing masks, but also car also need to "mask" - air conditioner filter to reduce vehicle particulate matter concentrations. Usually owners are in the maintenance replacement air filter, but with the increase in fog and haze and dust, recommended replacement air filter regularly, best replacement filter twice a year. If you don't know when to replace, you can use the OBD diagnostic tool detection.

Test results show that if there is no air conditioning filter, the concentration of the driver inhaled pollutants is much higher than the pedestrian path, like a vacuum cleaner, as the car's ventilation system inhalation of contaminated air contains particles and harmful gases, and every hours up to 420,000 liters of air through the filter, air conditioning, heating systems and bellows into the interior of the vehicle. Filter R & D personnel, over time, the filter core - will gradually clog the filter media, bellows capacity will be reduced by 50% to 70%. In order to ensure full and effective air filtration and good ventilation, air filters should be timely, regular replacement, you can use the Launch X431 PAD or Launch X431 Diagun III tool testing. Therefore, for long-distance drivers or often drive, the regular replacement of the filter is necessary.
