Troubleshooting BCM-U042829
Information
Hint: The diagnostic trouble code can be stored during brake control module (BCM) programming. If this is the case, erase the code.
- Ignition on
- Erase the diagnostic trouble code if it was generated during programming.
Was the diagnostic trouble code stored during brake control module (BCM) programming?
Yes - DONE
No - Checking diagnostic trouble codes in the central electronic module (CEM)
-------------------------------------------------
Checking diagnostic trouble codes in the central electronic module (CEM)
Checking diagnostic trouble codes (DTCs) in the central electronic module
Checking other diagnostic trouble codes (DTCs)
In the event of communication problems, the fault may exist in other parts of the communications network.
The role of the central electronic module is to generally control the communications network and to store diagnostic trouble codes (DTCs) in the event of communication problems between control modules.
If there are diagnostic trouble codes (DTCs) stored for communication problems in the central electronic module, stop the fault tracing and fault trace the central electronic module.
Were diagnostic trouble codes (DTCs) for communication problems stored in the central electronic module?
Yes - DONE
No - No Fault Found
------------------------
DONE - DONE
No Fault Found - Checking the diagnostic trouble codes (DTCs)
-------------------------------------------------
Checking the diagnostic trouble codes (DTCs)
- Ignition on
- Wait approx. 1 minute.
- Read the status of the diagnostic trouble code.
Is the status of the diagnostic trouble code intermittent?
Yes - Intermittent malfunction
No - Troubleshooting information
-------------------------------------------------
Troubleshooting information
The diagnostic trouble code indicates that the malfunction is in the steering angle sensor module (SAS).
Troubleshoot the system as described in relevant information. If no malfunction is found, replace the steering angle sensor module (SAS).

Intermittent malfunction
Hint: The diagnostic trouble code status indicates that the brake control module (BCM) has previously registered a malfunction, but the malfunction is no longer active.
Check the connectors of the brake control module (BCM) and the steering angle sensor module (SAS) for contact resistance and oxidation.
Also check that the cables are not positioned too close to a source of interference, such as a cellular phone.
Remedy as necessary.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
Do you want to view the information again?
Yes - Attempt New Test
No - FAULT FOUND
