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:
- Diagnostic trouble code (DTC) BCM-A030 is stored on its own. Refer to Erasing diagnostic trouble codes (DTCs) .
- Diagnostic trouble codes (DTCs) BCM-0108 and BCM-A030 are stored at the same time. Troubleshooting has been completed.
