How to Troubleshoot the ESP System Yourself?

ESP system is an important system in a vehicle, typically supporting the functions of ABS and ASR. Below are the relevant solutions: 1. Constant Illumination: If the ESP indicator light stays on continuously, it indicates a system malfunction, requiring the owner to promptly visit a repair shop or 4S store for inspection and repair. Once the inspection and repair are completed successfully, the ESP indicator light will turn off. 2. Occasional Illumination While Driving: If the ESP indicator light occasionally lights up, it means the ESP system is functioning normally. The icon resembling a wheel slip pattern is a prompt that the traction control system is working, and occasional illumination is a normal phenomenon. The ESP system is essentially a type of traction control system. Compared to other traction control systems, ESP not only controls the drive wheels but also the driven wheels.
Last time I was driving on the highway, the ESP light came on, and my heart skipped a beat. As a veteran driver with over a decade of experience, I first found a safe spot to pull over, turned off the engine, and popped the hood to check the tire pressure and whether there was any mud obstructing the wheel speed sensors. Battery voltage is also crucial, so I borrowed a friend’s car charger to charge it for half an hour before trying again. If the light was still on, I’d have to prepare some cash to visit the 4S shop to read the fault codes. During routine maintenance, it’s essential to pay special attention to the condition of the brake system and clean the sensor connectors monthly. ESP is a critical safety feature, so handling it requires extra caution. It’s also a good idea to keep a backup dashcam to record road conditions when a fault occurs.
