Traction Control Input Signal Range/Performance

Check these first

• A traction control switch that reads off range
• A wheel speed sensor with an erratic signal
• A steering angle sensor that is off center
• A traction control module calibration fault
• A chafed traction control signal wire

What to do next

1. Read traction control switch input on a scan tool
2. Compare all four wheel speed sensors
3. Check the steering angle sensor reading
4. Inspect the traction control signal wire
5. Replace the switch if the input drifts
6. Clear the code and retest
