Incorrect Steering Wheel Or Wheel Alignment
Incorrect steering wheel or wheel alignment
Checking the diagnostic trouble codes (DTCs)
Note! If diagnostic trouble codes (DTCs) are stored for the steering wheel module (SWM), wheel sensors or body sensor cluster stability sensor (BSC) (including the yaw sensor and lateral accelerometer), these must be fault traced first.
Are diagnostic trouble codes (DTCs) stored for the steering wheel module (SWM), wheel sensors or body sensor cluster stability sensor (BSC)?
Yes - DONE
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.
Other information
- Wheel angles, check Service and Repair
Were the steering wheel and front wheel alignment OK?
Yes - Intermittent fault
No - Calibration
-------------------------------------------------
Calibration
Calibrate the brake control module (BCM). See Vehicle communication, Calibration. Press "Pause". Save a bookmark so that the fault-tracing can be resumed after calibration.
Continue - Verification
-------------------------------------------------
Intermittent fault
Hint: The status of the diagnostic trouble code (DTC) indicates that the brake control module (BCM) has previously registered a fault but that the fault is not active.
Check the connectors for the brake control module (BCM) and the steering wheel module (SWM). Check for contact resistance. Check for oxidation.
Also check that the wiring for CAN communication is not too close to a source of interference such as a cell phone etc.
Remedy as necessary.

Verification
Verification
Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reconnect the connectors, components, etc.
- Test drive the car according to: Test Drive Form (DSTC (dynamic stability and traction control) /brake control module), description Test Drive Form (DSTC (Dynamic Stability and Traction Control) /Brake Control Module), Description
- Ignition on.
Read off the status of the diagnostic trouble code (DTC).
Is the status of the diagnostic trouble code (DTC) intermittent?
Yes - VERIFIED
No - VERIFICATION FAILED

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
