Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code information BCM-U030087

Condition




The brake control module (BCM) is factory-programmed with software for several vehicle models. During the first ignition cycle, the brake control module (BCM) reads vehicle configuration data from the central electronic module (CEM) and then configures itself to the vehicle model and equipment.
The diagnostic trouble code can be generated if
- a brake control module (BCM) that was previously in a different vehicle model is installed
- a central electronic module (CEM) that was previously in a different vehicle model is installed
- software for a different vehicle model has been downloaded to the brake control module (BCM).

Substitute value
- TC is blocked.
- SC is blocked.
- AYC is blocked.

Hint: For information on abbreviations: Brake system, abbreviations, B6324S5 Testing and Inspection

Possible source
- A brake control module (BCM) from a different vehicle model is installed.
- A central electronic module (CEM) from a different vehicle model is installed.
- Software for a different vehicle model has been downloaded to the brake control module (BCM).

Note! This diagnostic trouble code (DTC) is not due to an internal hardware fault in the Brake control module (BCM) and must not be remedied by replacing the control module.

Fault symptom[s]
- General warning light on.
- Anti-spin is not operational.
