Hva betyr feilkoden?
The four-wheel drive control module (DEM) checks how the oil pressure pump performs by comparing its current with predefined limits. The code is stored when the supply wire has a break, which shows up as an open circuit. The cause may be a damaged connector, a break or short to ground in the wire, internal leakage in the pump, or a damaged pump. The four-wheel drive is disengaged while the fault is present.
Mulige årsaker
- Damaged connector between the oil pressure pump and the four-wheel drive control module (DEM)
- Break or short to ground in the wire
- Internal leakage in the oil pressure pump
- Damaged oil pressure pump
Hva du kan gjøre
- 1Read and erase the code, then road test to see whether it returns
- 2Check the connector between the pump and the control module for damage, loose contact and oxidation
- 3Check the wire to the pump for breaks, damage and chafing, and that it does not touch the body
- 4If the code returns, have a workshop with diagnostic equipment check the pump, replace it if needed and calibrate the control module
Symptomer du kan merke2
- Four-wheel drive and all-wheel drive do not work
- Warning symbol and message in the display
Hva feilen kan påvirke1
- The four-wheel drive is disengaged while the fault is present
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
