Was bedeutet der Fehlercode?
The four-wheel drive control module (DEM) continuously receives the information it needs from the engine control module (ECM) over CAN communication, including the engine torque. If communication with the engine control module is lost, the code is set. The fault may lie in the engine control module, in the communication cable, or in the connections between them.
Mögliche Ursachen
- Fault in the engine control module (ECM)
- Open circuit in the communication cable
- Communication cable shorted to ground
- Communication cable shorted to voltage
- Contact resistance or oxidation in the connections
Was Sie tun können
- 1Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 2Test drive the vehicle to see whether the fault returns and whether four-wheel drive works
- 3If you have a diagnostic tool, read the engine control module fault codes first and remedy them before clearing this code
- 4Check the connectors on the communication cable for oxidation and loose fit, and follow the cable for chafing and pinched areas
- 5Use a multimeter to confirm the communication cable has no contact with ground or voltage
- 6If the fault remains, have a workshop check the engine control module and the CAN communication
Symptome, die Sie bemerken können1
- Four-wheel drive does not work
Was der Fehler beeinflussen kann2
- Four-wheel drive is disengaged
- Four-wheel drive has reduced function
