Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-U001012

Condition
The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- One of the cables on MS-CAN is short-circuited to voltage.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Starting the control module's CAN communication.

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
- Short circuit between one of the CAN cables and voltage.

Fault symptom[s]
