Hva betyr feilkoden?
The child lock on the driver side rear door sends no message to the CEM, so the control module receives no information from the function. The child lock then does not work, and a yellow warning symbol with a text message may appear in the display.
Mulige årsaker
- Damaged switch that shows the lock motor position
- The lock motor is stuck
Hva du kan gjøre
- 1If you have a diagnostic tool: read the fault codes in the driver and passenger door modules (DDM and PDM)
- 2Turn on the child lock with the switch on the driver's door control panel and check that the rear door then cannot be opened from inside
- 3Check that the fuse for the left rear door module is intact. Use a multimeter to check that the wire is not shorted to ground before replacing the fuse
- 4Look for chafing and pinch damage in the wiring to the rear door and check that the connectors are secure
- 5If the fault returns, have a workshop with diagnostic equipment check the bus and the control modules
