Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CVM-U012100

Condition
The control module is continually supplied with necessary information from the Brake control module (BCM) via CAN communication. The control module checks the communication with the Brake control module (BCM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- No communication with the Brake control module (BCM).
The control module's test for the diagnostic trouble code (DTC) starts when:
- The vehicle is in normal mode.
- Engine running.
- The voltage supply to the control module is 10-16 V.

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

Possible source
- Fault-trace in transmitting control module.
