Volvo-modeller feilkoden gjelder for
Gjelder følgende modeller:
9 modellerS60 (2011–), S80 (2007–), V40 (2013–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Hva betyr feilkoden?
The central electronic module (CEM) feeds the left brake light directly from an output. On V70 and XC70 one output feeds both brake lights, so both can be affected. The code is set when the signal is too low, which can be caused by poor contact or a short to ground.
Mulige årsaker
- Contact resistance, oxidation or play in the connections
- The signal wire is shorted to ground
Hva du kan gjøre
- 1Read and clear the code, then press the brake pedal and see whether the left brake light comes on
- 2Check that the bulb in the left brake light is intact
- 3Check the brake light fuse; on the V70 and XC70 the right brake light can also be affected, so check it too
- 4Check the connections to the left brake light 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
Symptomer du kan merke3
- The left brake light does not work
- Yellow warning symbol and text message in the display
- The bulb failure warning in the instruments comes on or behaves abnormally
Hva feilen kan påvirke3
- 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
