Hva betyr feilkoden?
The CEM checks the signal from the right solar sensor. The fault is stored when the signal from the sensor is too low, which is caused by the signal being short-circuited to earth.
Mulige årsaker
- The signal from the right solar sensor is short-circuited to earth
Hva du kan gjøre
- 1Check that the fuses for the climate control are intact
- 2If you have a diagnostic tool, check in live data that the solar sensor value changes when you cover and uncover it
- 3Check the connector at the solar sensor and the wire for chafing and pinch damage
- 4With the connectors disconnected, use a multimeter to check that the signal wire has no contact with earth
- 5If the fault returns, have a workshop check the solar sensor and the control module
Symptomer du kan merke2
- The air conditioning does not cool enough in the front part of the cabin
- The climate control does not work as it should
