Diagnostic Trouble Code (DTC) Information DEM-P066727: Notes
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
