BCM-A030

BCM-A030: Communications Between Control Modules, The Initialization 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.
