Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-P074812

Condition
The Differential electronic module (DEM) checks the performance of the control valve/the axial solenoid. The control module controls the solenoid by controlling the current via an internal control circuit. The control module checks the solenoid by comparing the current to the predefined parameters.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The current to the control valve/the axial solenoid is outside the predefined parameters.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine running.





Substitute value

- Four wheel drive is disengaged.

Possible source

- Short-circuit to supply voltage in the signal cable.
- Damaged Differential Electronic Module (DEM).

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