Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information BCM-A031
Condition
After the steering wheel angle sensor has been initialized, a check of the plausibility of the steering wheel angle is run.
The diagnostic trouble code (DTC) is stored if the check is not approved and speed exceeds 50 km/h.
The feasibility check can be performed after the relevant diagnostic trouble code is generated, but before the ignition is switched off. If the check is not complete within one minute, BCM-0111 is also generated.
Substitute value
- Active yaw control is blocked.
Possible source
- The plausibility check of the steering wheel angle is not approved.
Note! This diagnostic trouble code (DTC) is not due to an internal hardware fault in the Brake control module (BCM) and must not be remedied by replacing the control module.
