Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-U000111

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 HS-CAN is short-circuited to ground.
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.

Hint: Control module will remain shut off until the power supply is broken (15, 30, X). When the power supply is connected the control module will make a new attempt to communicate.

Possible source
- Short circuit between one of the CAN cables and ground.
