Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-U300362

Condition
The Differential electronic module (DEM) continuously checks its power supply. The control module compares the power supply to the Central electronic module (CEM) to its own power supply. Information about the power supply to the Central electronic module (CEM) comes from the CAN network.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The difference in voltage supply is greater than 2.0 V.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on for at least 10 seconds.





Substitute value

- Four wheel drive is disengaged.

Possible source

Signal too high
- Faulty power supply to the Central Electronic Module (CEM).

Signal too low
- Connector resistance and oxidation in the connectors.

Fault symptom[s]
- All wheel drive doesn't work
