Was bedeutet der Fehlercode?
The central electronic module (CEM) has registered a fault in the circuit to the second sun sensor, either a short to battery voltage or an open circuit. The second sun sensor also measures sunlight, so a fault affects the cabin temperature and the air conditioning.
Mögliche Ursachen
- Defective sun sensor 2
- Open circuit or short to battery voltage in the wiring to sun sensor 2
Was Sie tun können
- 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 connector to the sun sensor for loose connections and corrosion
- 3Use a multimeter to check that the wire to sun sensor 2 is not broken and has no contact with battery voltage
- 4If the wiring is intact and the fault remains, a workshop should replace the sun sensor
- 5Check that the air conditioning works properly after the repair
Symptome, die Sie bemerken können3
- 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 properly
