Hva betyr feilkoden?
The Central Electronic Module (CEM) controls the global opening and closing function for the windows and sunroof. The request for the sunroof is sent over a dedicated signal wire to the sunroof module (SRM). The fault is stored when the signal from the output is too high, which is caused by the wire being short-circuited to voltage.
Mulige årsaker
- The wire to the sunroof module is short-circuited to voltage
Hva du kan gjøre
- 1Check that the fuses are intact
- 2Test the sunroof with the switch and note whether it moves, then clear the code and road test
- 3Check the cable between the control module and the sunroof module for chafing and pinch damage
- 4Use a multimeter to check that the signal wire is not short-circuited to voltage
- 5If the fault returns, have a workshop with diagnostic equipment check the sunroof module
Symptomer du kan merke1
- Power sunroof does not work
Hva feilen kan påvirke3
- The function switches off during the driving cycle in which the fault is detected
- If the fault remains, the function is switched off permanently after 100 driving cycles where the fault was detected
- Erasing the fault codes or starting a new driving cycle resets the output
