Was bedeutet der Fehlercode?

The driver or passenger door module keeps getting its data from the central electronic module (CEM) and checks that the link is alive. The fault is stored when communication with the CEM is absent, which can be caused by a break, a short circuit or a poor connection in the communication wire, or by a fault in the CEM or in the network. Several door functions then do not work.

Mögliche Ursachen

Open circuit in the communication wire
The communication wire is short-circuited to ground or supply voltage
Contact resistance, oxidation or open circuit in the connections
The fault may lie in the central electronic module (CEM), which should be diagnosed first
If several modules also have communication faults, there is probably a common fault in the CAN network
The module is not intended for the car, for example a second-hand module with different software

Was Sie tun können

1Read the codes in the central electronic module (CEM) and diagnose them first
2Check that the fuses are intact
3Check that the connectors in the front door are secure and free from moisture and oxidation
4Inspect the wiring harness between the driver door and the CEM for chafing, pinching and visible damage
5Check whether several modules have communication faults at the same time, and if so diagnose the codes in the CEM first
6If the fault remains, have a workshop with diagnostic equipment measure on the CAN network and check that the module is intended for the car
