Hva betyr feilkoden?
The door module on the driver or passenger side feeds the central lock motor and the deadlock motor through a shared output. The control module has registered that one of the motors draws no current at all, or too high a current, when the central locking or the deadlock position is activated. Folding and electric adjustment of the mirrors may then be blocked as well.
Mulige årsaker
- Contact resistance, oxidation or poor contact in the connections
- Break in the wire running from the module to the central locking motor or the deadlock motor
- The shared wire from the module to both motors is short-circuited to supply voltage
- Wire from the module to the central locking motor short-circuited to supply voltage or ground
- Open circuit or short to supply voltage on the cable to the deadlock motor
- Power supply cable short-circuited to supply voltage, or with an open circuit
Hva du kan gjøre
- 1Check that the relevant fuses are intact
- 2With a diagnostic tool, read the fault codes in the door module; if there are codes for the central locking or deadlock motor, remedy them first
- 3Try the central locking and the deadlock position to see which functions do not work
- 4Use a multimeter to check that the wires to the central locking motor and the deadlock motor have no break and no contact with supply voltage or ground
- 5Look for moisture, oxidation and loose contacts in the connections to the motors and remedy them
Symptomer du kan merke3
- Locking, unlocking and central locking do not work
- Mirror electric adjustment does not work
- Mirror folding does not work
Hva feilen kan påvirke2
- While the fault is active, folding and electric adjustment of the mirrors are blocked to prevent the car being locked by accident
- All outputs that supply power to the lock motors are activated
