FixTraction Control or ABS Light — What It Usually Is
Traction control and ABS share their sensors, so their lights often come on together. The sensors live at each wheel — in the splash, salt, and rust zone — and they dominate the outcomes.

Light on, car drives normally
A wheel-speed sensor or its tone ring reading wrong is the usual story. Brakes work conventionally; the electronic safety nets are off until it's fixed.
Light flickers on rough roads
Intermittent faults over bumps are wiring — the sensor harness flexes with the suspension and eventually cracks. The fix is the harness or sensor, found with a scan tool's live data.
Comes on with a brake job due
Heavily worn brakes and wheel-bearing play can trigger the light too — the sensor is reading real wobble. The brake outcomes that dominate this complaint family reflect exactly that.
