Checking the diagnostic trouble codes (DTCs)

Note! If there are diagnostic trouble codes stored for steering angle sensor, wheel sensors or stability sensor (BSC), troubleshoot these first.

Select Diagnostics/Diagnostic trouble codes (DTCs) and read off the diagnostic trouble codes (DTCs).

Are there diagnostic trouble codes stored for steering angle sensor, wheel sensors or stability sensor (BSC)?

Yes - If there are diagnostic trouble codes stored for steering angle sensor, wheel sensors or stability sensor (BSC), troubleshoot these first.

No - Checking the front wheel alignment

-------------------------------------------------

Checking the front wheel alignment




- Adjust the front end before checking the steering wheel angle.
- Ignition on.
- Set the steering wheel to the straight forward position.
- Read off the steering wheel angle. With the steering wheel and the front wheels in the straight ahead position, the value for the steering wheel angle must be approximately 0°.
- Turn the steering wheel 90° to the right. Check that the value is correct.
- Turn the steering wheel 90° to the left. Check that the value is correct.
If the steering wheel angle does not correspond to the position of the steering wheel, reset the steering wheel angle and calibrate the dynamic stability and traction control (DSTC) system.
