Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information FSM-U012800

Condition
The control modules communicate with each other for exchange of information in a network via a standardized serial communication procedure - CAN (Controller Area Network).
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:
- Control module supplied with power.
- Engine running.

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.
