Checking diagnostic trouble codes (DTCs)

If diagnostic trouble code (DTC) BCM-A031 is stored on its own it must be erased.

If diagnostic trouble code (DTC) BCM-0111 is stored at the same time as BCM-A031, 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-A031 is stored on its own. Refer to Erasing diagnostic trouble codes (DTCs) .
2. Diagnostic trouble codes (DTCs) BCM-0111 and BCM-A031 are stored at the same time. Troubleshooting has been completed.
