Urgency:Safe to keep driving
Is it safe to keep driving?
Yes. A flashing light is the system doing its job. A steady light means you have no traction assistance, so drive as you would in a car without it.
Likely causes
- Wet, icy or loose road surface (flashing — normal)
- System switched off with the button
- Wheel speed sensor fault (often with the ABS light)
- Steering angle sensor needs recalibration after an alignment
Typical repair cost (US)
$0 – $400
Free if it is just switched off; a wheel speed sensor at the high end.
A typical range, not a quote. Actual cost depends on the car, the shop and the fault.
What to do now
- Check whether the traction control button was pressed.
- If it stays on with the ABS light, have the ABS code read.
