Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-P188949

Condition
The Differential electronic module (DEM) checks the performance of the oil pressure pump. The control module compares the current strength from the oil pressure pump to the predefined parameters.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The amperage through the oil pressure pump is greater than 0.5 A when the pump is off.
- Incorrect value lasts longer than 30 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.
- The oil pressure pump is switched off.

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
- Four wheel drive is disengaged.

Possible source
- Damaged Differential Electronic Module (DEM).

Fault symptom[s]
