Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information FSM-U041568

Condition
The control module is continually supplied with necessary information from the Brake control module (BCM) via CAN communication. The control module checks the quality of the information from the Brake control module (BCM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Transmitting control module indicates a lower quality level of the information than what Forward Sensing Module (FSM) accepts.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- 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.





Substitute value
- None.

Possible source
- Look for the cause of the fault in the brake control module (BCM).
