Hva betyr feilkoden?
The four-wheel drive control module (DEM) checks at start-up that the information stored in its memory is correct. The code is set when a checksum for the calibration data shows that the information is invalid. The check runs each time the ignition is switched on, and the fault lies in the control module.
Mulige årsaker
- Internal error in the four-wheel drive control module (DEM)
- Damaged four-wheel drive control module (DEM)
Hva du kan gjøre
- 1Read off the fault code, note it and clear it. Switch the ignition on and see if the fault returns
- 2Check that the battery is in good condition and that the fuses are intact, since weak voltage can cause faults in control modules
- 3If the fault remains, have a workshop replace the control module and calibrate it after the change
Symptomer du kan merke2
- Four-wheel drive does not work
- Warning symbol and text message in the display
Hva feilen kan påvirke1
- Four-wheel drive is disengaged for as long as the fault is present
