What does this fault code mean?
The control module has registered that the identity of one of the lower switches in the climate panel is missing, compared with the identities that should be in the car's configuration. The fault is probably a defective or missing switch, or a configuration fault. The control module then uses different values depending on which switch is missing.
Possible causes
- Defective switch
- Switch missing
- Fault in the car's configuration
What you can do

- 3If a switch is missing or damaged, have a workshop read off the switch identities and replace the switch if needed
