A steady ABS warning light on your Changan CS85 Coupe usually points to a wheel speed sensor, wiring, or tone ring fault. Here is what to check first and how safely to drive until it is repaired.
Why Your CS85 Coupe’s ABS Light Stays On
On a Changan CS85 Coupe, an ABS warning light that stays on continuously means the ABS control module has logged a fault and disabled the antilock function. The most common cause is a wheel speed sensor fault, but the sensor itself is not always the guilty part. Each wheel has a speed sensor that sends a signal to the ABS module, and the module compares those signals. If one sensor drops out, reads erratically, or its wiring is disturbed, the module sets a code and turns on the light. Other likely causes include a damaged sensor tip, chafed harness near the wheel arch, corroded connector, cracked or dirty tone ring, excessive wheel bearing play, or—less often—an ABS module or pump issue.
