Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-E003

Condition




The control module compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM). If the configuration IDs do not correspond the fault code is stored. The diagnostic trouble code (DTC) is also stored if the communication between the control module and the central electronic module (CEM) is interrupted.

Note! In the event of an open-circuit in both the control area network (CAN) cables, it is not possible to communicate with the control module. Therefore it will only be possible to read off the diagnostic trouble code (DTC) if this type of fault is intermittent. When the diagnostic trouble code (DTC) is stored, the control module responds to the diagnostic command, however normal control area network (CAN) communication does not work. ("Expulsion mode")

Substitute value
- None.

Possible source
- Faulty control area network (CAN) configuration ID. (The node is not intended for this car, for example a used control module with different software/hardware.)
- Open-circuit in the control area network (CAN) wiring between the control module and the central electrical module (CEM).

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]
- The ABS warning lamp is lit
- No ABS function
- Message in the display.
