Hva betyr feilkoden?
The door module supplies the central locking motor and the motor for the locked-locking function through a common output. The fault is stored when the motors either draw no current at all or draw too much, for example if a wire is broken or has contact with supply voltage. It is also stored if a motor draws current although no lock command has been given.
Mulige årsaker
- Contact resistance, oxidation or a loose connection in the connectors
- Break in the wire running from the module to the central locking motor or to the blocked-lock motor
- The wire to one of the motors is short-circuited to supply voltage or ground
- The common wire is short-circuited to supply voltage
- Open circuit in the supply wire
- A fault in one of the motors that stores its own code and should be diagnosed first
Hva du kan gjøre
- 1Read the fault codes in the door module: if there are codes for the central locking motor or the locked-locking motor, diagnose them first and then check whether this code returns
- 2Check that the fuses are intact
- 3Test the central locking with the key and the button and see whether any motor moves
- 4Inspect the wiring to the door and the connectors to the door module for chafing, pinching and moisture
- 5Use a multimeter to check that the wires have no break and no contact with supply voltage or ground
- 6If the fault remains, have a workshop with diagnostic equipment check the door module and the motors
Symptomer du kan merke3
- Central locking does not work, the doors cannot be locked or unlocked
- The mirrors cannot be adjusted electrically
- The mirrors cannot be folded in
Hva feilen kan påvirke1
