What does the ASR warning light indicate?

ASR warning light indicates a fault in the vehicle's ASR system. The ASR system is called the Snow/Slip Control System, also known as the Traction Control System. Situations when the ASR warning light comes on: 1. Maintenance or removal of tires may cause the ASR warning light to illuminate; 2. Insufficient tire pressure or air leakage issues, requiring a check for any leaks or low tire pressure; 3. In colder climates, the vehicle's grip decreases, especially on icy roads causing wheel slippage, which can also trigger the ASR warning light; 4. If the vehicle is equipped with an ABS system, it may also cause an ASR fault.
The ASR warning light on my car came on recently, which was really nerve-wracking. ASR stands for Anti-Slip Regulation, a system designed to prevent wheel slippage on rainy or muddy roads. I was driving on the highway when the light suddenly illuminated, making the car unstable and nearly causing a loss of control. After taking it to the repair shop, we found out the wheel speed sensor was clogged with mud—cleaning it fixed the issue. This kind of problem is usually caused by sensor malfunctions, control module issues, or wiring shorts. If not repaired promptly, braking distance on slippery roads can increase, which is extremely dangerous. I recommend keeping the sensor area clean and regularly scanning for OBD trouble codes. If the light comes on, avoid driving at high speeds and have it checked by a professional—don’t skimp on safety. Safety should always come first, and I learned that lesson the hard way.
