Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information DEM-P064F05

Condition
Information about the vehicle configuration is sent on the CAN network. Depending on the model and equipment, the vehicle can be configured in different ways. The central electronic module (CEM) sends the applicable signal ID for the vehicle. The differential electronic module (DEM) compares its configuration ID with the signal configuration transmitted on the network by the central electronic module (CEM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- These do not correspond, which means that the wrong software is programmed in Differential electronic module (DEM).
- Incorrect value lasts longer than 30 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on.

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 disconnected while the fault exists.

Possible source
- Incorrect software in Differential electronic module (DEM).

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