Co oznacza ten kod błędu?
The CEM has registered that communication with the PDM is not working. A door may then not lock or unlock from the passenger door buttons, and those buttons may stop working. The fault code points to a communication fault in the CAN network, so the CEM should not be replaced.
Możliwe przyczyny
- No power supply to the PDM
- Break in the earth wire to the PDM
- Contact resistance in the terminals
- Open circuit in the CAN wiring to the PDM
- The PDM is not meant for this car, for example a used module with other software or hardware
Co możesz zrobić
- 1Test the window switch up and down and the central locking button with the ignition on
- 2Check the fuse for the PDM in the passenger compartment fusebox
- 3Look for chafed wires or loose connectors at the passenger door
- 4If you have a diagnostic tool, read the module ID; if it can be read, communication is probably fine and the fault may be intermittent
- 5If the fault remains, have a workshop troubleshoot the CAN wiring
Objawy, które możesz zauważyć2
- Does not lock or unlock a door
