Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information TCM-U041500

Condition
The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network). If a control module registers a fault, the control module can then transmit a signal informing that its information cannot be trusted.
The diagnostic trouble code (DTC) is stored if the control module detects:
- The signal that indicates that the information from the brake control module (BCM) is incorrect.
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.

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