Do I need to repair the ESP system failure?

If there is a fault lamp, then it is best to go to the repair shop to read the fault code with the computer to see if it has anything to do with the problem, as long as there is a fault lamp on the instrument, we had better deal with it to prevent the vehicle from high fuel consumption and insufficient power.

ASR and ESP and tire pressure monitoring failures have been lit, the situation is not good, go to the 4S shop, if it is good, it is a collective false alarm of the computer, to eliminate the error code, eliminate the error code If you call the police in the future, detect your car computer system. It is estimated that the computer collectively gave false alarms

1. The basic principles for diagnosing common faults of automobiles can be summarized in 24 words: familiar with the structure, closely following the principle, observing the phenomenon, from the surface to the inside, first easy and then difficult, and less dismantling for benefit.

Second, this requires that on the basis of the structure and principle of leakage analysis, first comprehensively collect and understand all the phenomena of the fault, and then in use from the gradual appearance of the fault, the sudden appearance, the appearance before maintenance and the appearance after the overhaul, etc., to investigate in several aspects, to find out in what conditions and conditions the fault phenomenon is the most obvious. Under allowable conditions, the working conditions of the car can also be changed to observe various changes in the phenomenon, so as to grasp the characteristics of the fault phenomenon.

The ESP system is the stability control system of the vehicle, and its main role is to reduce slippage, side slip and loss of control when the vehicle is moving. If the ESP system fails, it can cause some of the following symptoms:

1.The vehicle loses control when turning or suddenly changing lanes, and it is difficult for the vehicle to control the normal driving.

2.The vehicle shakes when starting, accelerating, braking, or driving downhill, or there is abnormal feedback from the steering wheel or brake pedal.

3.The vehicle's ESP fault light or Zheng or stability control light is lit or flashing.

4.Notice that the parts of the vehicle emit abnormal noises, such as some sensors, braking parts or steering parts, these parts of the scum will affect the stability of the vehicle.

If you find that the vehicle has one or more of the above symptoms, it is recommended to go to the repair shop in time to overhaul and maintain the ESP system to ensure the safety performance of the vehicle.

Reasonable, I'm oh thanks!

ESP is also known as body stability system, and the failure of ESP body stability system will affect the stability of vehicle driving. For example, the vehicle flicks its tail and the tires slip Hongwei. When the strict draft is heavy, it will also affect the work of the ABS system, and the emergency braking of the vehicle will be locked.

An ESP system failure is a failure with no rev signal on the right front wheel.

If your vehicle's ESP lights are on, it is very likely that there is a problem with the stability system of the body, and it is best to send the leather waiter to the 4S shop for maintenance as soon as possible, because this is not a separate system, he is generally connected with the various configurations of the body, so the light is also very likely to be damaged because other functions have been damaged, if it is not repaired in time, it is very likely to threaten driving safety.

Solution: If the vehicle encounters the problem of ESP system failure during driving, it is best to park the car in time and set up roadblocks in front of and behind the vehicle to remind the passing vehicle that there is a fault in front of the grandson car, and then call ** in time to ask professional maintenance personnel to report for repair.

Do not continue to drive in the case of a fault, you must be clear about the cause of the fault, and the fault is located after the noise and then solve the symptoms, so as to best ensure the personal safety of the owner.

Fault phenomenon: The ESP indicator light on the dial of the instrument calendar is always on.

Troubleshooting process:

Check with VAS505X in the 03 items there is 00493ESP sensor unit no signal communication fault code, the fault code is static can not be cleared, due to the car mileage is very short preliminary analysis may be due to the possible reasons:

1. The plug-in connector of the ESP sensor unit is virtually connected.

2. The sensor control unit, but the J104 line of the ESP control unit is open or virtually connected.

3. Internal fault of ESP sensor unit.

4. ESP control unit failure.

It is found that there is no virtual connection phenomenon, and then remove the connector of the ESP control unit J104, measure the relevant line to G419, after inspection, it is found that there is a broken circuit phenomenon from the 24th pin of J104 to the 4th pin of G419, check the circuit diagram, the line is the CAN data line from J104 to G419, and the T17F 10 connector is also passed in the middle, the connector is a 17-core green plug-in, located on the left A-pillar terminal board, and the reed key found that the wire has been taken out of the connector after finding the connector, troubleshooting after repairing the connector.
