7 ModelleS60 (2011–), S80 (2007–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Was bedeutet der Fehlercode?
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.
Mögliche Ursachen
- The wire to the sunroof module is short-circuited to voltage
Was Sie tun können
- 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
Symptome, die Sie bemerken können1
- Power sunroof does not work
Was der Fehler beeinflussen kann3
- 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
