What does this fault code mean?
The climate control module (CCM) loses contact with the recirculation damper motor on LIN bus 1. Without a reply, it cannot switch between outside air and recirculation. The fault code may appear together with fault codes for other components on the bus.
Possible causes
- Break in LIN bus 1 wiring between the module and the recirculation damper motor
- Poor contact, corrosion or loose connections at the connectors
What you can do
- 1Check that the fuses are intact
- 2Check that the connectors to the damper motor and the climate control module are secure and clean
- 3Check with a multimeter that the LIN bus 1 wires are not open when the connectors are disconnected
- 4Try the recirculation mode and see whether the airflow changes
- 5If the fault remains and the wiring is intact, have a workshop replace the recirculation damper motor
Symptoms you may notice1
- No recirculation of the air
