Mercedes-Benz Steering Angle Sensor Calibration Without Scan Tool
Reviewed/Verified by:
How can I reset the steering angle sensor on my Mercedes-Benz? This guide provides instructions on how to reset the Mercedes-Benz GLK Class steering angle sensor without a scanner. Follow the procedures below to learn how to reset the steering angle sensor of your Mercedes-Benz GLK without a scanner.
At a Glance
- Use after a battery disconnect, when ESP warnings appear with a straight wheel.
- Engine running, car stopped: turn lock to lock twice, then center the wheel.
- Drive straight for a couple of minutes to finish the relearn.
- After sensor replacement or an alignment, calibrate with a scan tool instead.
- Persistent warnings: read the ESP codes.
- A scanner such as the YOUCANIC UCAN-II Pro runs Mercedes steering angle sensor calibration on supported models when the simple routine is not enough.
Procedure
- Start the engine. Step on the brake pedal and push the engine start button.
- Once the engine is on, turn the steering wheel all the way to the left stop, then all the way to the right stop, with the car stationary. Repeat this twice, then center the wheel.
- Drive your vehicle for two minutes. You have completed the steering angle calibration and reset the steering angle sensor.
When this does not work
This simple routine relearns the center position after a battery disconnect. If the ESP or steering warnings stay on, or the sensor or clock spring was replaced, or the wheels were aligned, the sensor usually needs a calibration with a scan tool that supports Mercedes. Read the ESP codes first; a wheel speed sensor fault can set the same warnings.

Can I calibrate a Mercedes steering angle sensor without a scanner?
After a battery disconnect, turning the wheel lock to lock with the engine running and then driving straight often relearns it. After a sensor replacement or alignment, a scan tool is usually needed.
Is it safe to drive with an ESP warning after a battery change?
The brakes work normally, but stability control may be off. Try the relearn routine, and read the ESP codes if the warning stays on.
