Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-P188914

Condition
The Differential electronic module (DEM) checks the performance of the oil pressure pump. The control module compares the signal from the oil pump to the predefined parameters.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The amperage from the oil pressure pump is less than 0.3 A.
- Incorrect value lasts longer than 30 seconds.
The control module's test for the diagnostic trouble code (DTC) starts when:
- The oil pressure pump voltage is 4.8 V or greater.

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 connector between oil pressure pump and Differential electronic module (DEM).
- Short-circuit to ground in the voltage supply cable.
- Open-circuit in the voltage supply cable.
- Damaged oil pressure pump.

Fault symptom[s]
- 4-wheel/all wheel drive/Does not work
- Text window and warning symbol/Text message
