What does this fault code mean?
The telephone module (PHM) communicates with the driver door module (DDM), but gets no reply from it when the ignition is on. The cause may be a damaged fuse, a missing power supply or earth to the module, poor contact in the connections, a module not intended for the car, or a break in the CAN network. The driver door switch panel then does not work.
Possible causes
- Damaged fuse
- No power supply to the driver door module (DDM)
- Break in the earth wire to the driver door module (DDM)
- Contact resistance or oxidation in connector terminals
- The driver door module (DDM) is not intended for this car, for example a used unit with different software or hardware
- Break in the CAN network
What you can do
- 1Check the fuse for the driver door module in the fuse box. Its location is shown in the owner's manual or on the cover of the box
- 2Switch the ignition on and run the driver window up and down. If the window lifter works, the supply to the driver door module is probably in order
- 3Check that the connectors at the driver door module and at the telephone module are firmly seated and not corroded
- 4If the fault remains, have a workshop trace the driver door module, its supply and the CAN network with diagnostic equipment
