Car steering wheel jitter causes and solutions

Car steering wheel jitter, is our daily driving in the process of one of the most common vehicles problem, especially the vehicles driving to 50000 km to 70000 km between the most easy to appear this kind of phenomenon. Steering wheel jitter, body resonance will lead to not safe driving, need to use Auto Diagnostic Tool in time to check the performance of the car.

Cars driving speed at between 80-90 km, will appear steering wheel jitter, more than 90 kilometers per hour is back to normal. This happens mostly caused by the tire deformation or vehicle transmission system, must use the Launch X431 GDS or Launch X-431 PADII tools to check whether the front wheel orientation Angle and the toe-in meets the requirements, such as loss of quasi should be adjusted; Set up front axle try to turn the wheel, wheel static balance condition and examine whether the tire deformation is too large, such as deformation should be replaced.

Traveling on a flat road vehicle normal, but encountered potholes, steering wheel jitter. This is due to the car in the driving, because of the pull rod ball head wear loose or glue joint fall off, as there is a tire wear and tear become irregular, should be sent to the professional repair point inspection, replacement of damaged parts.

Vehicle at 30-40 km per hour, the body has shake feeling, like the feeling of by boat. This happens mostly because the tires when used in daily due to causes such as brush, bump or aging and other reasons caused by the deformation caused, by the replacement of tires.

At high speeds the steering wheel appeared jitter when suddenly hit the brakes. Brake too hard, often may cause brake disc, brake pads, overheating, encounter cold deformation, caused by steering wheel vibration. Usually in the replacement of brake pads, brake pads, symptoms can be resolved, in order to drive the vehicle safety, should be regularly used Xtool PS2 or Autel MaxiSys Pro MS908P tools to check the performance of the car.

Brake fluid selection and usage guide

Automotive brake fluid is what we usually say brake fluid. Brake fluid is auto transmission brake pressure in hydraulic system of a liquid medium. Brake fluid when the choose and buy, the higher the level of the brake fluid, is better. So if the quality of the brake fluid problems, what consequence can you produce? Such as brake failure, etc. But people often ignore the inspection and replacement of the brake fluid, so it is necessary to regularly use the OBD Diagnostic Tool to check the brake fluid.

When long-distance driving, the engine is in operation for a long time, or in the summer temperatures are high, these will be used to increase the temperature of the brake system. If you are using low boiling point of the brake fluid evaporation will make brake system steam pipe filled with steam, produce gas resistance, thereby blocking the brake fluid diversion pipe, it can cause brake failure phenomenon, so you need to use Launch X431 V Pro or Launch X431 Diagun III tools to check the car's performance. So the good quality of the boiling point of the brake fluid is relatively high, so the brake fluid and good abrasion resistance and liquidity and the viscosity is moderate.

As long as we open the hood, you will find there are a milky white jar, that is used to hold the brake fluid place, you can see the inside of the brake fluid, outside marked with upper and lower limits of the scale, if the liquid level in its it shows the range of the normal amount of brake fluid. If you want to add brake fluid, it is necessary to add the same level now use the same brand of the same quality brake fluid, otherwise it will layer because of different formula or produce chemical change, influence the reliability of the brake fluid, reduce the braking effect.

So you must be pay more attention to the use of the brake fluid, brake fluid generally use 1-2 years later will replace, if you don't know what time replace, you can use the Autel MaxiSys Pro MS908P or Xtool PS2 tool inspection. Brake fluid when the choose and buy, in order to avoid buy the fake and shoddy products, you'd better choose in some famous brand of brake fluid, even the after-sales service is also very perfect.

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.

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 maintenance automobile suspension systems

Is the so-called suspension system, between the wheel and the vehicle body, take on the job of carrying the body and absorbing the vibration, to provide the best comfort. Under normal circumstances, the shock absorber may have a fever, if you do not explain the fever shock absorber oil spills. Car driving, each time shaking up and down, the suspension will be rattled, and when the uneven road surface noise intensified, it means suspension system malfunction, may be a shock absorber damage or shock absorber rubber sleeve damage. If you are not sure what the reason, you can use Auto Diagnostic Tool to check the car's performance.

Suspension - Shock Absorber check
Suspension system not only affect vehicle ride comfort, but also as through sex, stability and adhesion performance impact on other properties. The original is in the suspension system includes shock absorbers, springs, anti roll bars, rods and other parts. In turn, especially a sharp turn, body roll is too large, indicating that the damper, stabilizer bar, or is the guiding mechanism parts are damaged.

Brake System - Brake oil brakes
In daily use, to use Launch X-431 PAD or Launch X431 V+ Pro3 tool to check whether the vehicle brake deviation, braking performance how, and how the effect of the parking brake (handbrake) is. In the maintenance of the vehicle, the brake system must first be carried out in the brake oil inspection, such as the brake pipe is cracked, brake oil leakage, etc.. The brake pedal is also a part of the need to pay attention.

After you replace the brake pads, check whether the brake pedal return to normal, daily driving time to pay attention to prevent the mat to slide under the brake pedal, so the brakes can not be trampled to death.

Brake system plus brake fluid can not be mixed, at present, the market most cars are equipped with two braking systems: foot-controlled brake (brakes) and hand control of the parking brake (handbrake). Replace the brake fluid, must take the original brake oil finished, cannot mixed with, more can not be mixed with air inside the brake fluid. Generally speaking, the brake pads wear degree with habits have great relationship, automatic car brake pads with better than manual transmission fast, generally more than 20000 kilometers later, each time to do maintenance to use Autel MaxiSys Pro MS908P or Xtool PS2 tool to check the car brake pads. This can better protect the suspension system. If the rubber sleeve is badly damaged, it must be replaced with the shock absorber.

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.

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!

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.

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.

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.

Maintenance and inspection method of automobile shock absorber

Automotive shock absorber is used to suppress the shock of spring when the shock and the impact from the pavement. The spring can be used to filter the vibration of the pavement, but the spring itself will have a reciprocating motion, and the shock absorber is used to suppress the spring jump. Through Auto Diagnostic Tool checking, the shock absorber is too soft, the body will be jumping up and down, shock absorber is too hard will bring too much resistance, interfere with the normal work of the shock absorber. Teach you how to maintain the working effect of shock absorber and how to check it.

1, Oil seal gasket, sealing gasket rupture damage, storage cylinder cover nut loose. May be oil seal, seal gasket damage, should be replaced with new seals. If you still can not eliminate oil leakage, should pull out spring strut, if feel the card or not at that time, light and heavy, then, using the gap between Launch X431 V Pro or Launch X431 Diagun III tool to check the piston and cylinder is too large, shock absorber piston connecting rod for bending, the piston connecting rod surface and the cylinder have scratches or marks.

2, Press firmly on the bumper, then release, if the car has 2 or 3 times to jump, then the shock absorber works well.

3, when the car slowly driving and emergency braking, if the car more intense vibration, there is something wrong with the shock absorber.

4, Remove the shock absorber to its upright, and the lower end of the connecting ring folder on the vise, pull compression damping lever several times, then there should be a stable resistance, pull up resistance should be greater than pressed down resistance, such as resistance to unstable or no resistance may be internal shock absorber valve parts lacking fuel or damage should be repaired or replaced.

5, in determining the shock absorber problem or failure, should first check the shock absorber for leaks or traces of old oil spills.

6, To make the car drive 10km on the poor condition of roads on the road parking, touch the shock absorber shell, if not very hot, no resistance in the shock absorber, shock absorber does not work. At this point, can be added to the appropriate lubricating oil, and then test, if the shell fever, for the shock absorber internal lack of oil, should refuel; otherwise, the shock absorber failure.

7, if the damper does not leak phenomenon, should check the shock absorber connection pin, connecting rod, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If these were normal, should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without injury, the valve seal is good, the valves and valve seat are tight fitting and Save Dilatation shock absorber spring is too soft or broken, take grinding to repair or replace parts of the approach according to the situation.

8, In addition, shock absorber in actual use will rattle the fault, which is mainly due to the shock absorber and the steel plate spring and frame or shaft of the collision, the rubber pad damage or loss and damper dust-proof cylinder deformation, caused by insufficient oil should be to identify the reasons, to be repaired.

9, shock absorbers after the inspection, repair should be in a special test stand performance test, when the resistance frequency at 100 ± 1mm, which stretch stroke and stroke compression resistance should meet the requirements, showed normal shock absorber.

I suggest that you use by bumper way to check on how the working conditions of the shock absorber. Because this approach is simple and relatively less time-consuming, but also very intuitive and accurate test results. You should regularly check the shock absorbers have no oil leakage, and if there is leakage oil will affect its work, should go to 4S shop use professional Autel MaxiSys Pro MS908P or Autel MaxiSys Mini MS905 tools for maintenance.

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 maintain the car automatic transmission

Now city traffic condition is getting worse, car stop-go situation has become the habit of the driver. So, portable, easy these two features automatic car has quietly become the first choice for most people. Although automatic car easy and convenient, but because of the automatic transmission system is very sophisticated, if the automatic transmission fails, we need to use a professional OBD Diagnostic Tool repair, and expensive, and therefore, the automatic transmission need to be more careful care and maintenance.

The automatic transmission oil can not only play the role of lubrication cooling, but the main thing is to transfer power between the engine and gearbox. Lubricating oil temperature is generally around 120 degrees Celsius, so demanding on the quality of the oil, and must be kept clean. First frequently used Launch X431 V Pro or Launch X431 IV GX4 Master tool to check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, need to be preheated to about 50 ℃, the gear lever again after a short stay in each block in the parking and the oil dipstick corresponding normal oil level should be between the highest and the lowest line, if not, should be added in time.

In most cases, when we replace the automatic transmission oil is to remove the screw automatic transmission oil pan to miss the old oil then add new oil, but this can only put about a small part of the new oil, and there Most of the old oil remains in the gearbox. If demolition sump oil change way, you can put 70 percent of the new oil, so as to ensure the transmission of health. Presently preferred method is dynamic oil change oil change, using a dedicated gearbox cleaning equipment, the full cycle of old oil, drained and then add new oil, so that the oil change rate of 90%.

As the vehicle traveling road is rather special, road congestion, poor air quality, is easy to cause transmission oil oxidative deterioration, according to Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool inspection data indicate that the deterioration of the transmission oil increased wear of friction between the film and increase fuel consumption, if not to change new gearbox oil for a long time, will cause oil particles increases and block oil, blocking the plunger, and even a shift impact, so the transmission oil must be replaced periodically.

Air filter and car battery maintenance guide

Everybody for car batteries and air filter should be familiar with. So we usually listen to music while driving in the open air or blowing cold air, which must support the job by a car battery. And if the battery is no electricity or damage, the car is unable to start, so the need for regular use Auto Diagnostic Tool to check the vehicle battery. Then the air filter plays a filtered air entering the engine, to provide clean air for the engine, reducing engine running wear. Today we take a look at the two components of the maintenance guide.

Car battery:
General, automotive battery life is two years. Some owners usually well maintained, can extend this use time. If maintenance do not get bit, less than two years to be replaced. If the battery has been aging and not timely replaced, repeated charging and discharging can damage the internal battery plates and an electrolyte. through Launch X431 Diagun III or Launch X431 V+ Pro3 tool check data show that: the battery capacity will be reduced and eventually run out of power, the engine can not be started.

Air filter:
General car mileage of forty thousand kilometers or two years can be considered to replace the air filter. If it often in some dusty environment, the replacement cycle would go ahead of some. If no timely replacement of the air filter, increases mileage and filter clogging. And reducing engine power, accelerate the ability to reduce, reduce fuel economy, cylinder due to dirt and damage, air supply is insufficient.

So now we should all know the importance of car batteries and the air filter. Just remember that your battery and air filter coming two year when we should use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check usage, it should be replaced. Usually in the car maintenance cycle time, we must check the battery and air filter, if there is a serious aging, damaged the situation, it should be replaced.

How to maintenance of automatic transmission oil filter

Filter is the key projects when we maintenance to the car, oil filter, air filter, fuel filter, the so-called "three filter" Conservation has always been a point of attention. In addition to these three common commonly used filters, there is a transmission oil filter, its maintenance methods very few people know, is very simple, just use the OBD Diagnostic Tool can be.

The conservation process in the daily inspection car, the car transmission oil filter is rarely mentioned, unless damaged, affecting the transmission operation, otherwise, its maintenance is easy to be overlooked in. Because in most cases, transmission oil filter is not like oil, air or fuel filter as easy to replace. In fact, since the automatic transmission oil, ATF filter is a device for protecting the second main assemblies, so it should be kept clean or replaced in time according to the Launch X431 V Pro or Launch X431 IV GX4 Master equipment recommended by the manufacturer.

The automatic transmission usually paper filter, felted membrane filter or oil filter to filter out the dirt. Asian carmakers like using a membrane filter; and European and American manufacturers are more inclined to paper or felt filter.

Some car manufacturers have introduced long-life or maintenance-free transmission. The transmission no dipstick device and its normal maintenance, ATF and filter replacement cycle of up to 160,000 km / h.

For the ATF filter, you can't judge the performance of the filter, unlike oil filter to be replaced follow along as oil, unlike the air filter, you can take it down and clean it, transmission oil filter can only rely on inspection and maintenance process maintenance personnel inspection tips. It also reminds us that we must have understand of basic car maintenance knowledge, or you can use the Autel MaxiSys Pro MS908P or Autel MaxiSys MS908 professional equipment to check the filter work performance.

Lubricating oil color black need to be replaced immediately?

Many drivers see lubricant color black, they think oil quality has been a serious deterioration, and replace it, resulting in waste. Normally, car oil at just replaced, color is golden yellow, are generally will added clean dispersant, the purpose is to wash the adhesion and black carbon deposition film on the piston down and dispersed in oil, reduce engine generate high temperature deposits, so the use of lubricants colors tend to darken after a period of time, but this time the oil does not deteriorate, the use of oil is serious deterioration, needs to be replaced by the Auto Diagnostic Tool can determine whether the need to replace, is not observed the oil color black, concludes that need to be replaced lubricant.

Under normal circumstances, regardless of any brand of lubricating, its life cycle can be maintained at more than 5,000 km, to the 8000 km -10 000 kilometers need to replace oil. Only when the long-term bad driving habits, such as frequent Jicha, refueling too fast, the speed at 3000 rpm or more frequently, oil change intervals will advance.

After a period of time, engine oil the color will gradually darken, why lubricant color will change to black?
First, the fuel in the olefin content, sulfur content is high (gasoline engine is easy to form sludge, diesel engines easy to form smoke stains), easy to make the engine oil black, and thus fuel quality is the source of oil black.

Second, the different structure and working conditions of the engine, it is easy to make gasoline engine oil sludge generated, form smoke stains incomplete combustion of diesel engine, thus lubricant turning black, you can use a Launch X431 V Pro or Launch X431 Diagun III tools to check these phenomena.

Third, In order to overcome the fuel and mechanically induced results, lubricating oil to adding dispersant to prevent sludge or smoke stains on the cylinder formation deposited in the film or the body, the higher the quality of the oil, dispersed better, but oil is volatile black, so high quality oil, than the poor oil variable black faster.

Fourth, Oil color black produced sludge is related to launch a pilot time overly high temperature operation, and not to clean the engine when the car in the oil and oil bottom, associated with the filterability of oil filter.

Engine oil replacement time, premature cause lubricating oil waste, too late will increase engine wear and shorten engine life and maintenance cycle, so you need to use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the engine. The deterioration degree of lubricant has relationship with the performance of automobile, repair technology, driving level, road and weather condition, lubricant quality, etc, uniform regulations drain intervals sometimes not entirely realistic. If after a period of use of lubricants appear dimmed color, white, indicating filling oil mixed with water, which emulsion occurs. The basic properties of lubricants has been completely lost, the engine cooling system and combustion system for leaks, should not continue to use.
