Volvo-modeller feilkoden gjelder for
Gjelder følgende modeller:
5 modellerC30 (2007–2013), C30 Electric (2011–2013), C70 (2006–2013), S40 (2004–2013), V50 (2004–2013)
Hva betyr feilkoden?
The central electronic module (CEM) has registered that the circuit to the second sun sensor is short-circuited to ground. The sun sensor is used so the climate system can match the cabin temperature to the sunlight, so a fault means the temperature and air conditioning do not work as they should.
Mulige årsaker
- Defective sun sensor 2
- Short to ground in the wiring to sun sensor 2
Hva du kan gjøre
- 1Read and clear the code, then check whether the climate system reacts when the second sun sensor is covered by hand and lit with a flashlight
- 2Check the sun sensor connector for loose connections and corrosion
- 3Use a multimeter to check that the wire to sun sensor 2 has no contact with ground (the body)
- 4If the wiring is intact and the fault remains, a workshop should replace the sun sensor
- 5Check that the air conditioning works after the repair
Symptomer du kan merke3
- Passenger compartment temperature is not reduced in strong sunlight
- Passenger compartment temperature does not match the set position
- Temperature control and air conditioning do not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
