Incorrect Steering Wheel or Wheel Alignment
Incorrect steering wheel or wheel alignment
Checking diagnostic trouble codes (DTCs)
Note! If diagnostic trouble codes (DTCs) are stored for the control module for the steering angle sensor, wheel sensors or active yaw control sensor (including the yaw sensor and lateral accelerometer), these must be fault traced first.
Are diagnostic trouble codes (DTCs) stored for the steering angle sensor, wheel sensors or active yaw control sensor?
Yes - DONE
No - Checking diagnostic trouble codes (DTCs)
-------------------------------------------------
Checking diagnostic trouble codes (DTCs)
- Ignition off.
Check whether the active yaw control sensor is loose or incorrectly installed. See Active yaw control sensor, replacing Active Yaw Control Sensor, Replacing.
Is the active yaw control sensor secure?
Yes - Checking the connectors
No - Verification
-------------------------------------------------
Checking the connectors
- 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°.
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.
If the front wheel alignment does not correspond to the position of the steering wheel, adjust the front end and calibrate the dynamic stability and traction control (DSTC) system.
Other information
- To reset the steering wheel angle sensor, see Contact reel / steering wheel angle sensor, replacing Contact Reel / Steering Wheel Angle Sensor, Replacing
- To adjust the front end, see Wheel alignment, checking / adjusting Service and Repair.
Were the steering wheel and front wheel alignment OK?
Yes - Intermittent fault
No - Calibration
-------------------------------------------------
Calibration
- Ignition on.
Calibrate the brake control module (BCM).
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 control module for the steering wheel angle sensor. Check for contact resistance and oxidation.
Also check that the wiring for CAN communication is not too close to a source of interference such as a carphone etc.
Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reconnect the connectors, reinstall components etc.
- Test drive the car. See 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

VERIFICATION FAILED - Fault-tracing information
VERIFIED - Fault Found
PAPER - No Fault Found

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - FAULT-TRACING FAILED
No - Attempt New Test

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).
