What does this fault code mean?
The instrument cluster (DIM) gets no reply from the driver door module (DDM), which among other things sends information to the instrument cluster. Communication between them has stopped, so functions controlled from the driver door may show faults in the instrument cluster.
Possible causes
- Break in the communication wire
- The communication wire is shorted to earth
- The communication wire is shorted to supply voltage
- Poor contact, oxidation or breaks in the connections
What you can do
- 1Read and note the fault codes, clear them and road test the car to see whether the fault returns
- 2Check the fuses in the fuse box. Their location is in the owner's manual or the fuse list
- 3The driver door module often controls the window regulator and the door lock. Check whether they work, as this helps show where the fault is
- 4Check that the wiring harness to the driver door is not chafed or pinched, especially where it enters the door
- 5If the driver door has recently been worked on, check that all connectors are properly reconnected
- 6If the fault returns, have a workshop with diagnostic equipment check the module and the CAN network
Symptoms you may notice1
