Hva betyr feilkoden?
The climate control module (CCM) has received a checksum in a message on LIN bus 1 that does not match. This means the signal from a component on the bus is not correct. The fault may be caused by interference or by two components on the bus having the same ID.
Mulige årsaker
- Communication interference
- Two LIN nodes with the same ID are installed in the car
- A damper motor may be installed in the wrong position, for example one for recirculation in place of one for air distribution
Hva du kan gjøre
- 1Check that the damper motors sit in the correct positions for their specific IDs
- 2Check that the seat heating module (SHM) sits in the correct position
- 3Has a damper motor recently been replaced? If so, check that it is fitted in the right place
- 4Clear the code and road test the car to see whether it returns
- 5Have a workshop read and check the ID of the connected control modules
Symptomer du kan merke5
- Airflow does not work as it should
- No recirculation of the air
- Temperature control is uneven
- Poor heating in the cabin
- Temperature control or air conditioning does not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
