What Causes the Anti-Slip Light to Stay On?

When the anti-slip system light is on, it indicates that the ESP is turned off or has malfunctioned. Generally, there are several possible reasons: 1. The car may frequently drive on slippery roads, causing the ABS to activate, which is why the light often comes on. 2. Accidentally pressing the ESP off button. In this case, simply restart the engine or briefly press the ESP OFF button on the vehicle to check if the ESP was turned off by mistake. 3. Malfunction of the car's ABS pump. This requires inspection and repair at a 4S shop. 4. Signal transmission error in the car (such as loose or faulty sensor connectors, short circuits in the wiring, or related fuse blowouts). In this case, the fuse needs to be replaced.

I've been driving for many years and have encountered the situation where the anti-skid light stays on a few times, usually indicating an issue with the vehicle's traction control system. The most common cause is a dirty or faulty wheel speed sensor, which is prone to dust accumulation or water ingress near the wheels. For example, last time I drove in the rain, the light stayed on, and after inspection, it turned out the sensor wire for the right front wheel was loose—fixing it solved the problem. If the sensor itself is faulty, it needs to be replaced; it's not expensive but requires a visit to the repair shop. Other possibilities include a malfunctioning ABS control module or issues with the steering angle sensor, which are more complex. It could also be due to low battery voltage causing a false alarm—I once experienced this in winter with an aging battery. A constantly lit anti-skid light affects driving safety, especially on slippery roads, increasing braking distance and the risk of skidding. It's recommended to drive to a professional shop for diagnosis immediately when the light comes on, avoiding DIY fixes that might worsen wear. Regular cleaning of the undercarriage and sensor areas during car washes can help prevent such issues.

When driving, I always pay attention to safety details, and a constantly illuminated anti-skid warning light is definitely something to be cautious about. The most common issue is sensor failure, particularly damage to wheel speed sensors or signal interruption. Sometimes, rough road conditions or water accumulation can trigger temporary errors, which may disappear after restarting the vehicle. However, if the light remains on persistently, it indicates the system is alerting you to a failure in stability assistance, such as an increased risk of skidding during turns. I once experienced this on the highway—after the light came on, the car struggled to accelerate, and a later inspection revealed a corroded and broken cable connector that needed replacement. Other potential causes include the need for control system software updates or aging chassis components like shock absorbers affecting the vehicle's posture. It's advisable to slow down when the light is on and promptly use diagnostic tools to check for fault codes, as ignoring it could lead to increased fuel consumption and wear. The anti-skid system is a critical component of active safety, so don't push your luck by delaying repairs.

As a new car owner who loves to delve into car knowledge, I've consulted my repair-savvy friend about the traction control light staying on. The main cause is often sensor issues, with wheel speed sensors being the most common culprit—check for mud buildup or damage. System errors can also trigger the light; try turning off the engine and restarting. If it persists, visit a repair shop to scan for trouble codes and pinpoint the issue. A lit traction control light affects ABS and traction control functions, increasing wheel lock-up risk during hard braking. Don't ignore it to avoid elevating accident risks.
