Volvo-Modelle, für die dieser Fehlercode gilt
Gilt für folgende Modelle:
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) monitors the voltage supply to the reversing lights. The code is set when the signal from the output is too low, which can be caused by poor contact in the connections or a signal wire shorted to ground.
Mögliche Ursachen
- Poor contact, oxidation or play in the connections
- The signal wire is shorted to ground
Was Sie tun können
- 1Clear the code and check the reversing lights by engaging reverse gear
- 2Check that the reversing light bulbs are intact
- 3Check the reversing light fuse
- 4Check the connections to the reversing lights for oxidation and play
- 5Use a multimeter to check that the signal wire has no contact with ground (the bodywork); otherwise have a workshop check the module output
Symptome, die Sie bemerken können1
- The reversing lights do not work
Was der Fehler beeinflussen kann3
- The function switches off during the driving cycle in which the fault is detected
- After repeated driving cycles with the fault, the function is switched off permanently
- Clearing the fault codes and starting a new driving cycle resets the output
