Diagnostic Trouble Code (DTC) Information DEM-P060254
Condition
The differential electronic module (DEM) checks the software calibration. The control module has a number of parameters that can be calibrated, oil temperature, oil flow, solenoid current etc. The parameters must have a default value. The parameters value is checked internally in the control module.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The default values are missing or incorrect.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.
NOTE:
The control module is calibrated together with the control valve/the axial solenoid during production. This cannot be carried out on the after market.
Substitute Value
- Four wheel drive is disengaged.
Possible Source
- Calibration not done
- Calibration fault
Fault symptom[s]
- All wheel drive doesn't work
