BCM-A030

BCM A030 Communication between Control Modules (The initialized check has not been run)

Condition





The steering wheel angle sensor is initialized when the steering wheel is moved at least 5° within a certain amount of time of the ignition being switched on. Diagnostic Trouble Code (DTC) BCM-A030 is stored if the steering angle is not initialized after 2 minutes driving at a speed above 10 km/h. The initialization can be run before the ignition is switched off even after Diagnostic Trouble Code (DTC) BCM-A030 has been stored. The anti spin warning lamp then goes out. Diagnostic Trouble Code (DTC) BCM-0108 is also stored if the initialization is not completed before the ignition is switched off.

Substitute value
- Active yaw control is blocked.

Possible Source
- The steering wheel angle sensor is uninitiated after two minutes driving above 10 km/h.

Fault symptom[s]
- The anti-spin warning lamp is lit (up to and including 2002 model year)
- General yellow warning lamp lit (from model year 2003 inclusive)
