Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-P066727

Condition
The Differential Electronic Module (DEM) has a temperature sensor fitted on the control module's circuit board. If the temperature rises too quickly, four-wheel drive disengages. This is to protect the control module.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The temperature increases at a speed greater than 10 °C/s.
- Incorrect value lasts longer than 50 ms.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine running.

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 during the time the fault exists, and is disengaged a further 30 seconds after the fault has disappeared.

Possible source
- Damaged temperature sensor in the control module.
- Damaged Differential Electronic Module (DEM).

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