What causes the ESP light to come on in a car?
1 Answers
Reasons for the ESP light coming on: ESP is the electronic stability system, which may be caused by loose wiring, poor wheel alignment, sensor issues, or ABS pump failure. The benefit of the ESP light coming on is to alert the driver to promptly check and repair at a 4S shop. The ESP system is actually a type of traction control system. Compared to other traction control systems, ESP not only controls the drive wheels but also the driven wheels. For example, rear-wheel-drive cars often experience oversteering, where the rear wheels lose control and cause the car to fishtail. In such cases, ESP will brake the outer front wheel to stabilize the car. In cases of understeering, to correct the tracking direction, ESP will brake the inner rear wheel to adjust the driving direction.
