Was bedeutet der Fehlercode?

The current in the control circuit to the oil pressure pump is outside the expected range, and the four-wheel drive control module (DEM) detects this while driving. The cause can be an electrical fault in the cable, such as a short to voltage or to ground, or an internal leak in the pump.

Mögliche Ursachen

Damaged connector between the oil pressure pump and the control module
Voltage supply cable shorted to voltage
Voltage supply cable shorted to ground
Open circuit or short to ground in the cable
Internal leak in the oil pressure pump
Damaged oil pressure pump

Was Sie tun können

1Read off the fault code, note it and clear it. Test drive the vehicle to see if the fault returns
2Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
3Follow the wiring between the control module and the pump for chafing, pinched areas and loose clips, and check the connector at both ends
4Use a multimeter to confirm the cable has no contact with ground (body). With the ignition on, also check whether the cable has voltage when it should not
5If you have a diagnostic tool, read the pump current in live data with the engine running and check whether the value is steady or jumps
6Have a workshop check the pump and replace it if it is damaged, and calibrate the control module after the change
