Co oznacza ten kod błędu?
The climate control module has received a signal that is too high from the outside temperature sensor on cars with electronic climate control (ECC). The fault is intermittent and has occurred earlier without being present now. Because the signal is wrong, the cabin temperature may end up differing from the selected setting.
Możliwe przyczyny
- Contact resistance or oxidation in the connections
- Open circuit in the signal or ground cable
- The signal or ground cable is short-circuited to supply voltage
- Defective outside temperature sensor
Co możesz zrobić
- 1Check that the connector to the outside temperature sensor is firmly seated and that the contacts are not corroded
- 2Use a multimeter to check that the signal and ground cables have no open circuit
- 3Use a multimeter to check that the cables are not live when the ignition is off
- 4If you have a diagnostic tool: read the outside temperature in live data and check whether the value changes after the car has been driven for a while
- 5If the fault returns even though the wiring is intact, have a workshop replace the outside temperature sensor
Objawy, które możesz zauważyć1
- The cabin temperature does not match the selected setting
Na co może wpływać usterka1
- The system uses the outside temperature that was last stored
