What Causes the Vehicle Anti-Slip Light to Illuminate?
2 Answers
The reasons for the vehicle anti-slip system light to illuminate are: 1. Accidentally pressing the ESP off button; 2. Loose or faulty sensor connectors; 3. Short circuit in wiring or related fuse blown; 4. Software issues causing poor signal transmission; 5. ABS pump failure. When the anti-slip system light is on, it indicates that the ESP is either turned off or malfunctioning. The anti-slip system, known as ESP, functions to monitor the vehicle's driving conditions. During emergency obstacle avoidance or turns, if understeer or oversteer occurs, it helps prevent the vehicle from deviating from the ideal trajectory. ESP integrates three systems: ABS (Anti-lock Braking System), BAS (Brake Assist System), and ASR (Acceleration Slip Regulation System).
Recently, the traction control light in my car suddenly came on, which really worried me. The traction control light may illuminate due to issues with the wheel speed sensors – these often get contaminated by dirt or water, causing the system to mistakenly detect wheel slip. It could also be caused by uneven tire pressure or severe tire wear, triggering the system to detect imbalance. Another common reason is a faulty ABS control module, which can render the entire traction control system inoperative. Sometimes the light comes on legitimately when driving on slippery roads, but if it stays on constantly, that indicates a malfunction. My advice is to pull over immediately when the light comes on, check if tire pressures are correct, and inspect for even tread wear. If that doesn't resolve it, visit a repair shop to scan for trouble codes. Safety first – this system prevents rollovers, so don't ignore malfunctions as it could lead to accidents during cornering or rainy conditions. During regular maintenance, pay attention to cleaning around the sensor areas.
