Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-0007

Condition




The Differential electronic module (DEM) checks the oil pressure in the Haldex clutch using an oil pressure sensor.
When the engine speed exceeds 500 rpm, an initial pressure builds up in the clutch via an electric feed pump.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Initial pressure not reached within 2-4 minutes.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine speed (RPM) higher than 500 rpm.

Substitute value
- Four wheel drive is disengaged.

Possible source
- Damaged pressure sensor.
- Damaged feed pump.
- Too low oil volume in clutch.
- Internal leak in the clutch.

Fault symptom[s]
- Four wheel drive is not functioning.
