Checking diagnostic trouble codes (DTCs)

If diagnostic trouble code (DTC) BCM-A030 is stored on its own it must be erased.

If diagnostic trouble code (DTC) BCM-0108 is stored at the same time as BCM-A030, read off the diagnostic trouble codes (DTCs) from the control module for the steering angle sensor. Fault-trace the system.

Select an option:

1. Diagnostic trouble code (DTC) BCM-A030 is stored on its own

   Refer to Erasing diagnostic trouble codes (DTCs) 

2. Diagnostic trouble codes (DTCs) BCM-0108 and BCM-A030 are stored at the same time.

   OKAY:  Troubleshooting has been completed.
