Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-U010000

Condition
The control modules in the vehicle send and receive information continuously on the vehicle's controller area network (CAN).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Interrupted or missing communication with the Engine control module (ECM).
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- Stability control (SC) blocked.
- Traction control (TC) blocked.
- Active yaw control (AYC) is blocked.

Hint: Brake system, abbreviations Brake System, Abbreviations

Possible source
- Disruption or intermittent open-circuit on the Control area network (CAN).
- Locate the cause of the fault in the engine control module (ECM).

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.
