Hva betyr feilkoden?
The rear electronic module (REM) controls the relay for the rear A/C and checks the signal to its coil. If that signal is too high, which may be due to a short to supply voltage in the relay circuit or a defective relay, the code is set. The rear A/C then does not work.
Mulige årsaker
- Short circuit to supply voltage in the relay circuit
- Defective relay
Hva du kan gjøre
- 1If you have a diagnostic tool, activate the rear A/C relay and listen for a click
- 2Check that the rear A/C relay is in place and does not appear damaged
- 3If the relay is defective or the fault remains, have a workshop replace the rear A/C relay
Symptomer du kan merke1
- The rear A/C system does not work
