Co oznacza ten kod błędu?
The climate control module (CCM) compares its supply voltage with the voltage in the central electronic module (CEM). The fault only needs fixing if it has been active for a long time and you notice that a function does not work; otherwise it can be cleared. The cause may be contact resistance or a damaged supply wire.
Możliwe przyczyny
- Contact resistance
- Damaged supply voltage wire
Co możesz zrobić
- 1Check that the battery is charged and that the battery terminals are clean and tight
- 2Check that the fuses are intact
- 3Check with a multimeter that the voltage at the climate control module connector is steady when the ignition is on
- 4Look for chafed or corroded wires in the supply
- 5Clear the code and road test the car to see whether it returns
Objawy, które możesz zauważyć2
- Climate control does not work at all
- Temperature control or air conditioning does not work
