Common Symptoms

Stability control light on
Traction control warning light
ESC disabled until sensor is calibrated
Code appears after alignment or steering repair
Advanced driver assist features unavailable

Probable Causes (Ranked by Likelihood)

Steering angle sensor not calibrated after repair or alignment Very High
Failed calibration attempt due to unlevel surface High
Battery disconnected without subsequent sensor recalibration Moderate
Scan tool calibration procedure not completed properly Moderate
Sensor hardware fault preventing calibration Low

Step-by-Step Diagnostic Procedure

Attempt steering angle sensor calibration with a scan tool on level ground
Verify the steering wheel is centered before starting calibration
Turn the steering wheel fully lock-to-lock during calibration if required
Ensure the vehicle is on a flat, level surface during calibration
If calibration repeatedly fails, check for sensor hardware faults or wiring issues

Frequently Asked Questions

How do I calibrate the steering angle sensor?

You need a scan tool that supports your vehicle. Access the ABS or ESC module, select the steering angle sensor calibration function, and follow the on-screen instructions. This usually involves centering the steering wheel and may require a short test drive.

Can I calibrate the sensor without a scan tool?

Some vehicles have a self-calibration procedure that involves turning the steering wheel full lock-to-lock and then centering it. However, most modern vehicles require a scan tool for proper calibration.

Why did the calibration fail?

Common reasons include the vehicle not being on level ground, the steering wheel not being centered, the tires not being straight ahead, or the vehicle being moved during calibration. Some vehicles also require the engine to be running.
