Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information FSM-U040268

Condition
The control module is continuously supplied with necessary information from Transmission control module (TCM) via CAN-communication. The control module checks the quality of the information coming from Transmission control module (TCM).
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.
