The diagnostic trouble code (DTC) is stored if the battery voltage to the central electronic module (CEM) is significantly higher than the battery voltage to the trailer module (TRM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The system voltage differs by more than 2.0 V.
Starting the control module's CAN communication.

Substitute value
- None.
