Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-P056017

Condition
The Differential electronic module (DEM) continuously checks that the power supply to the control module is within its permitted range. The Differential electronic module (DEM) compares the power supply (signal) to the predefined parameters.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The power supply is higher than 18.5 V.
- Incorrect value lasts longer than 3 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

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 generator (GEN).

Fault symptom[s]
- 4-wheel/all wheel drive/Does not work
