What does it mean to display ESC maintenance on the dashboard of the car

The dashboard of the car shows that the ESC maintenance is an ESC fault indicator light is on, and the electronic stability system has an error. 、

Generally, there is an alarm caused by the software system, or it may be caused by sensor failure or short circuit of the line, and it is not excluded that there is a false alarm, and a special fault diagnostic instrument is needed to troubleshoot and determine, and it is sent to the 4S store for maintenance as soon as possible.

The main function of ESC is to make the car more stable and safe when changing lanes or cornering, and the ESC system does not work under normal driving conditions. When the ignition is on, the ESC is activated, the warning light is on, and the ESC off indicator lights up and turns off after about 4 seconds. When the ESC fault on the car is always on, it means that the ESC of the vehicle is faulty, and the vehicle's electronic stability control is not working at this time.

ESC is mainly composed of sensors, actuators and electronic control units (ECU) three parts, any part of the failure will cause the ESC fault light to light up, we can try to restart the engine when the ESC alarm light is on, and then press the ESC off button on the vehicle, and finally restart to see if the alarm light is on caused by a false fault.

The function of automotive ESP is to help the vehicle maintain dynamic balance by analyzing the vehicle driving status information transmitted from each sensor, and then sending correction instructions to ABS and ASR. Rear-wheel drive cars often have too much steering, when the rear wheels are out of control and flicking, the ESP will brake the outer front wheels to stabilize the car, and when the steering is too small, in order to correct the direction of tracking, the ESP will brake the inner rear wheels to correct the direction of travel. The ESP system consists of a control unit, steering sensors, wheel sensors, side slip sensors, lateral acceleration sensors, etc.

The ESP includes several functions: electronic brake distribution system, anti-lock braking system, tracking control system, and vehicle dynamics control system.

Explain the problem of the body stability system, it is recommended to check what the specific fault code is first, I hope mine is helpful to you, and the car master wishes you a happy car. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, this is a problem with the electronically controlled stability system [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Please check the ESC, indicating that the car's electronic stability system is faulty. It is necessary to use a diagnostic instrument to detect the fault code of the electronic stability system to eliminate the fault, and the owner should arrive in time4S shopCheck it out.

This system mainly controls the longitudinal and lateral stability of the vehicle to ensure that the vehicle drives according to the driver's consciousness. The basis of the electronic stability control system is the ABS anti-lock braking function, which brakes continuously hundreds of times a second when the tires are about to lock up when the car is braking, which is somewhat similar to the mechanical "point brake".

In this way, when the vehicle is fully braking, the tires can still ensure rolling, and the rolling friction effect is better than the sliding friction effect after locking, and the driving direction of the vehicle can be controlled.

On the other hand, the system works in tandem with the engine ECU, and when the drive wheel slips, the electronic system automatically reduces the throttle by comparing the speed of each wheel and comparing the speed of each wheel.

Air intake, which reduces engine speed and thus power output, brakes slippery drive wheels.

This reduces slippage and maintains the optimal power delivery between the tires and ground grip, so that the drive wheels do not slip no matter how much oil is applied.

ESP is particularly sensitive to over-penetration or understeer when the steering side shouts group, for example, when the car turns left when the road is slippery, it will overturn and turn too sharply to the right side, and the sensor will quickly brake the right front wheel to restore adhesion, resulting in an opposite torque to keep the car in the original lane. Of course, everything has a range of degrees, and if the driver blindly drives fast, it is difficult for any safety device to ensure its safety.

The situation that the car needs to be repaired ESC means that the car's electronic stability system is out of order. Defense.

If the ESC indicator is green, it is normal and anti-slip. If the ESC indicator is yellow, the electronic stability control system is malfunctioning.

ESC is an electronic vehicle stability control system and driving safety supplement that helps to avoid hazards and compensates for the stability of the vehicle by means of wheel brakes or control of engine torque when the vehicle is extremely unstable when making quick turns or changing lanes. When your vehicle is in an extremely unstable situation, the ESC function works automatically.

Extended information: The ESC system can help you improve vehicle stability and prevent skidding in harsh driving conditions. It is recommended to keep the system on. In the event that sufficient traction is not achieved, the ESC system can be switched off.

If you are driving on a deep snow or muddy road, or if your vehicle is stuck and you need to drive out of the stuck area.

The ESC system is to use the computer to control the engine output and brake at any wheel (the braking force is divided into sizes) when the vehicle is turning rapidly, dodging or avoiding the car or animal that suddenly breaks out, when the vehicle sliding outward due to understeering, or oversteering causes the vehicle to cross the road centerline or even rotate in situ, so as to eliminate the phenomenon of understeer or oversteer and improve the dynamic stability of driving.

Please overhaul the meaning of ESCTire pressureInsufficient, or caused by ABS sensor, wiring harness failure, etc., the specific cause needs to be detected by computer.

ESC stands for Electronic Body Stability System.

Meaning, the car suddenly prompted to repair the ESC electronic body stability system, indicating that the system failure requires the maintenance of the ESC electronic body stability system can control the engine torque output, when it fails, even along with the engine fault lights are lit up.

ESC Role:

Electronic stability control is an active safety technology that assists the driver to control the vehicle, which can automatically correct the instability of the body and help prevent accidents.

ESC applies advanced sensing technology to determine the driver's intentions in the direction of travel, and when the vehicle begins to deviate from the road, the system initiates an intervention to apply braking force to one or more wheels, reducing engine valve intervention and guiding the vehicle back to the correct course.

The car prompts that the ESC system failure of the car means that the ESC electronic car stability control system has failed, and the electronic stability control system of the vehicle does not work at this time. The ESC fault indicator light is a more complex fault problem, which is generally caused by the alarm caused by the software system, and may also be caused by sensor failure or short circuit of the line, which is more troublesome to detect, and it is best to go to the 4S shop in time for inspection and maintenance.

Press the ESC off button on the dashboard** to dismiss ESC. When the ESC function is deactivated (the ESC off indicator is on), if the ESCoff button is pressed again, the system will enable ESC, the ESC off indicator on the dashboard will turn off, and the ESC system will continue to work.

Automotive ESC System Considerations.

1. When the vehicle travels to about 40km h, there will be a "pop" sound, which is the sound of ESC self-inspection.

2. When the vehicle is just started, some vehicles prompt "ESC off", the normal working voltage of the ESC system is 9V-16V, when the battery itself is insufficient, and the voltage drops below the normal working voltage at the time of starting, an alarm will be triggered, if the battery is fully charged or the generator is powered normally after the vehicle starts, this alarm will be canceled and will not affect the normal operation of ESC.
