Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

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:
- Communication with the Park Brake Module (PBM) lost.
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
- None.

Hint: Brake system, abbreviations Brake System, Abbreviations

Possible source
- Disruption or intermittent open-circuit on the Control area network (CAN).
- Fault-trace the Park Brake Module (PBM).

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]
- Electrical parking brake; Reduced Functionality
