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.

How to clean EFI engine fuel injection system

EFI engine is currently on the vehicle use a very wide range of equipment, compared with the conventional carbureted fuel system, EFI engine fuel supply system, not only complex, but also parts with precision. When using Auto Diagnostic Tool maintenance necessary to pay special attention.

During cleaning maintenance, some parts can not be disassembled and dismantled, some parts assembly requirement is high, which makes gasoline injection system than the carburetor type vehicles are more vulnerable to the dangers of gasoline in the colloid, sediment, the cleaning is very complex.

The engine fuel supply system, the air inlet and exhaust system are clean and have a decisive influence on the driving performance of the vehicle. Due to the impact with the environment and fuel quality injectors, intake manifold, intake and exhaust valves and the combustion chamber is easy to produce gelatinous precipitates, etc., affect the normal fuel supply, cause by fuel injection quantity control is not accurate, the fuel spray is bad, the oil pressure regulation failure, which causes the engine idle speed instability, the acceleration bad, knock, lack of fire, fuel consumption, exhaust emissions exceed the failure phenomenon. These faults can be using the Launch X-431 PAD or Launch X431 Creader VIII tool checked out.

In order to clean the oil supply system to solve the problem from the inside, they usually avoid demolition clean way. Vehicle cleaning jobs by special Autel MaxiDas DS708 or Autel Maxidiag Elite MD701 tools and equipment and cleaning agents, under certain pressure and flow control, intake manifold, fuel injectors, intake and exhaust valves and combustion chamber thorough cleaning to restore the normal operation of the fuel system, to ensure good driving performance of the car.

How to buy high-quality car brake oil

Speaking of automotive brake systems, we naturally think of the importance of the brake pads, it has been a normal reaction to contact with safety, another key element for automobile brake system -- brake oil , people don't really care, but don't know it is a key link in automobile braking systems, the relationship between the owners of personal safety. According to Transportation Department data shows that If all people use the brake oil, every year to reduce the 10% traffic accident, how to buy high-quality brake oil, need to use Auto Diagnostic Tool.

Currently on the market the brake oil is divided into three types: type of alcohol, mineral oil and synthetic type. Alcohol and mineral oil has been eliminated, market of brake oil for the synthesis of type, common brake oil have DOT3, DOT4, DOT5, most of the cars used are DOT4 brake oil.

How to buy brake oil?
1, different types and different brands of brake oil do not mix, due to the different synthetic ingredients, mixing brake fluid can cause brake oil index declined, If you use the Launch Creader VII or Launch X431 Creader VIII tool, it's easy to see the change.

2, the normal running of the vehicle, If the brake suddenly light or suddenly heavy, to the timely replacement of brake oil, before replacement, first with alcohol will brake system clean.

3, when the brake oil sucked moisture or impurities, should be replaced or the filter, otherwise it will cause the brake pressure insufficiency, the effect of the brake. There are some places the weather is wet, this is particularly important.

4. Vehicle braking wandering, to the braking system to conduct a comprehensive inspection. If discover wheel cylinder cup expansion is too large, brake oil quality there could be a problem. At this time should choose quality good brake fluid replacement, replace the leather bow at the same time.

Clean, high-quality brake oil is the basic of good work condition of safety and brake system. Vehicle on 40,000 km or brake oil continuously used for more than two years, then the brake oil needs to be replaced. When choosing the brake oil to note that if the use of inferior brake oil, brake pump will rot burning Pusey, use Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to check the brake pump to see whether the work is stable, will also have an impact on the brake effect, so if the brake oil lack, it is best to specialized shops to buy the original car brake oil, the original brake oil use effect is very good, can also prolong the service life of the system of brake.

The six functions of fuel additive

Function one, lubrication. Fuel additives replacing lead to lubricate the upper part of the engine block, the engine is smooth, not dry, improved power, lower fuel consumption. If you want to know more information, you can use the OBD Diagnostic Tool to check.

Function two, full combustion. When burned, small water microemulsion particle effect at high temperatures swept into the steam generation "micro-explosion" so that the combustion flame propagation is more uniform and delicate, so that the gas atomization is improved, so as to achieve complete combustion.

Function three, antioxidant. Fuel additive antioxidant ingredients can inhibit from fuel components in unstable components and a little olefin diene in the environment under the effect of temperature and air oxidation condensation formation of glial process, avoid the metal surface oxidation of automobile engine, to ensure the normal work of the engine. You can use the Launch X431 Creader VIII or Launch Creader VII tool to test the performance of the engine.

Function four, rust protection . Fuel in the storage and use process, there will be water, can cause rust, oil system for vehicle fuel additives can prevent the rust of pipelines and oil system.

Function five, anti-corrosion. Fuel to meet in the process of transportation, storage, use water caused by the oil emulsion, the oil-water boundary and form slag emulsion cream, cause the clogging in filter, and oil emulsification easy to moisture into the air intake system and combustion chamber corrosion and impact the normal operation of the engine, and composition of demulsification can prevent corrosion and affect the normal operation of the engine.

Function six, clean. Fuel additives contain pollutants, it has been adhered to in other parts of the heating surface grease, gum and carbon deposits in the combustion chamber of the role of pine, making it easy to be in the air in "clear", and after combustion exhaust. Carburetor vehicle hydraulic system, EFI car nozzle, intake valve has the function of keeping clean, using Autel MaxiTPMS TS401 or Autel AutoLink AL609 tool reads the carburetor real-time data.

How to correctly use car navigation systems

Now many owners like to put a navigator in the car, which is equivalent to a portable electronic maps, navigation systems owners can use common sense to operate, or operate in accordance with the product instructions, and sometimes you can use Auto Diagnostic Tool, so you can save a lot of time, take a look at the correct way of using the navigator.

1. We do not recommend put the navigator on the dashboard, especially in the summer, the sun direct lighting causes navigator damage.

2. Buy a new navigator first charge at least 10 hours.

3. to start the car, after inserting the cigarette lighter power, after the end of the navigation unplug the cigarette lighter, and then plug the next start vehicle, which will help protect the machine battery, extending battery life, you can use the Launch X431 Creader VIII or Launch X431 CResetter II tools to detect cars performance.

4. Beside the navigator don't put the sharp things, so as not to damage the navigation screen.

5. After the shutdown sequence to follow this: Close the page, and then shut down, and finally unplug it, some owners diagram easy, used directly pull the plug, never shut down, this is easy, but a long time is easy to damage Electronic components.

General method enabled car navigation systems. Push in the SD memory card, do not write-protected SD card to the front toward the front of its host, the SD memory card gently into the jack switch to [OFF] in advance of Location So, when the first time, please switch to the position [ON], and enter the main interface, you can then start using the car navigation system; a delay when the screen can not be switched, the button does not work or touch Tap the pen system does not respond, press the [RESET] holes button to reset the system, can also be used Autel Maxidiag Elite MD701 or Autel Maxidiag Elite MD703 tools to reset.

How to prevent car spontaneous combustion

In summer, the car ignition incidents continue to occur, in fact, the majority of vehicles spontaneous combustion are to be expected. Automotive body noise, a coke burnt taste, smoke is likely to be the precursor of spontaneous combustion. In case of spontaneous combustion, the car personnel should immediately leave the car, you can use the OBD Diagnostic Tool to detect vehicle performance, professional advice, occur in hot weather, the owner of car maintenance should pay attention to the following points:

First, check the oil. We usually find that a lot of cars have symptoms of chassis oil spill , in the hot season, which is likely to be the cause of spontaneous combustion. And the spontaneous combustion accident at ordinary times is also for oil. Hence the need for frequent use Launch X431 V Pro or Launch X431 Creader VIII tool to view the car, if the engine oil spills, oil spills chassis tubing signs of aging or broken it should go to a professional repair shop or 4S shop maintenance.

Second, check the circuit. More than three years of car especially modified car headlights, modified car stereo should be comprehensive examination. Car circuit fire occupy a considerable proportion of spontaneous combustion events. Engine, ignition coil, high temperature, high voltage ignition wire insulation softening, aging, dehiscence, high-voltage ignition easy breakdown of the insulating layer, it is easy to produce high-voltage leakage, leading to spontaneous combustion.

Third, after the car stopped immediately shut down the engine , to develop good driving habits. The hot season, the ground temperature is higher, when parked idling and others, the maximum temperature of the exhaust pipe under the car, even higher than 800 ℃. If there is a parking ground hay, paint, or other flammable items, for a long time under the baking will be on fire, and burn the car.

Fourth, Clean up the car of inflammable and explosive materials. The male driver of friends like lighters on the center console, in the hot season, this habit will become very dangerous. Another perfume contains more alcohol, and very easy to fire. Now a lot of automotive interior materials generally do not have fire resistance in case of fire, the fire spread easily.

Summer is the high incidence of car ignition, the car ignition, generally due to a short circuit electrical wiring or inside the vehicle flammable materials. To avoid spontaneous combustion to reduce the chance of your car, regular maintenance regularly, but every car with at least one Autel MaxiTPMS TS601 or Autel MaxiTPMS TS401 tools, check the car function.
