What is the reason for the ASR light on a truck?
2 Answers
ASR light on indicates that there may be a fault in the vehicle's traction control system. The solutions are as follows: 1. The vehicle should be sent to a 4S shop for inspection and repair as soon as possible. Such faults are usually caused by wiring issues and require a fault diagnostic tool to identify the cause. After repair, the fault light can be cleared. 2. The ASR light may also be on because the ASR off button (ESP-OFF button) was pressed. You can try pressing the button again and check if the indicator light on the dashboard disappears. If it does not, proceed to a 4S shop for repair.
That day when I was driving a truck to deliver goods, the ASR light suddenly came on, which gave me a scare. ASR is the anti-slip system, mainly preventing wheel slippage during acceleration, and the light usually indicates a system issue. Common causes include dirty or faulty wheel speed sensors, which are located near the wheels and prone to getting muddy or aging. Or it could be a fault in the system control unit—last time I encountered a blown fuse that caused the light to stay on. There might also be loose wiring or a short circuit, especially since truck wiring can wear out over time. Once the light comes on, the system might not function, so drive carefully, avoid sudden acceleration, and it's best to find a safe place to pull over, check it out, or visit a repair shop. Regular maintenance, like cleaning the sensor areas, can help prevent such situations.
