Internal fault

Reading off diagnostic trouble codes (DTCs)




- Ignition on
- Read off diagnostic trouble codes (DTCs).
If any other codes than BCM-0050 are stored, these must be fault-traced first.





Were any diagnostic trouble codes (DTCs) other than BCM-0050 stored?

Yes - DONE

No - Erasing diagnostic trouble code (DTC)

-------------------------------------------------

Erasing diagnostic trouble code (DTC)




- Ignition on.
Erase the diagnostic trouble codes (DTC).






Continue - Checking diagnostic trouble codes (DTCs)

-------------------------------------------------

Checking diagnostic trouble codes (DTCs)




- Ignition off
- Check the brake control module (BCM) connector. Check for contact resistance and oxidation
- Wait a couple of seconds
- Ignition on
- Read off diagnostic trouble codes (DTCs).
Replace the brake control module (BCM) if diagnostic trouble code (DTC) BCM-0050 is still stored as a permanent fault.

Was diagnostic trouble code (DTC) BCM-0050 stored as a permanent fault?

Yes - Fault Found

No - Fault-tracing information

-------------------------------------------------

Fault-tracing information
The control module has previously registered a fault but the fault is no longer active. Check that the wiring is not too close to a source of interference such as a carphone etc.


Yes - No Fault Found
