Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-U042268

Condition
The control module continually supplies necessary information from the Central electronic module (CEM) via CAN communication. The control module checks the quality of the information from the Central electronic module (CEM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The transmitting control module indicates a lower quality level of information than Brake control module (BCM) accepts.
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
- Fault-trace the central electronic module (CEM).
