What does this fault code mean?

The driver and passenger door modules (DDM/PDM) check their own internal components and compare their configuration ID with the ID that the central electronic module (CEM) sends out on the CAN network at regular intervals. If the IDs differ, or the ID is missing for a longer period, the code is set. The module then still answers diagnostic commands, but normal CAN communication does not work (“Expulsion mode”).

Possible causes

Faulty software in the control module
Incorrect configuration ID, for example a used control module intended for another car or with different software or hardware
Open circuit on one or both CAN wires in part of the network, which makes the module unreachable

What you can do

1Read and clear the code, then run a test drive to see whether it comes back
2If you have diagnostic equipment, read the codes in the central electronic module (CEM) first, as they show whether the fault is wider than one control module
3Check that the door module is intended for this particular car, especially if it is a used module from another car
4Check the fuses in the fuse box and make sure they are intact
5Have a workshop download the correct and latest software to the door module or reprogram the configuration; replace the control module if it cannot be configured for the car

Symptoms you may notice5

Electric adjustment of the mirrors does not work
Folding of the mirrors does not work
The electric window does not work, works with reduced function or works incorrectly
Locking and unlocking with the central locking does not work
The child lock in the doors does not work

What the fault can affect3

The control module stops sending messages on the CAN network
The control module still responds to diagnostic commands
The control module's functions stop working

General guidance for car owners. Diagnosis on the car can point to a different cause.
