Volvo-modeller feilkoden gjelder for
Gjelder følgende modeller:
5 modellerC30 (2007–2013), C30 Electric (2011–2013), C70 (2006–2013), S40 (2004–2013), V50 (2004–2013)
Hva betyr feilkoden?
The CEM cannot communicate with the passenger door module (PDM), so the passenger door cannot be operated from the central locking switch and the switch panel in the door does not work. The most common cause is a damaged fuse, supply, earth or a connector at the PDM, but the LS-CAN wiring can also be the fault.
Mulige årsaker
- Damaged fuse
- No supply to the PDM
- Open circuit in the earth wire to the PDM
- Contact resistance in the connections
- Open circuit in the LS-CAN wires to the PDM
- The PDM does not suit the car, for example a used module with other software or hardware
Hva du kan gjøre
- 1With the ignition on, try the window buttons in the passenger door. If the window moves, the PDM has power and the fault is likely in the communication
- 2Check the passenger door fuses in the engine bay fuse box and in the CEM. If one has blown, check its circuit for a short to earth
- 3Use a multimeter to check that the earth wire from the PDM has no break
- 4Check the connector at the PDM for loose connections, corrosion and damage
- 5With a diagnostic tool, read the PDM ID. If it reads, the CAN communication is probably fine and the fault may be intermittent
- 6The CEM normally does not need replacing for this code, because the fault lies in the communication with the door module
Symptomer du kan merke2
- The passenger door cannot be operated from the central locking switch
- The switch panel in the passenger door does not work
Hva feilen kan påvirke1
- The PDM goes into limp-home mode, so the door functions are only partly available
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
