Was bedeutet der Fehlercode?
The CCM relies on the evaporator sensor reading to regulate the A/C compressor. The code is set when the signal is too high, for example after an open signal or ground wire, or a short circuit to voltage.
Mögliche Ursachen
- Open circuit or short to voltage in the signal wire
- Poor contact, corrosion or a loose plug in the connectors
- Open circuit or short to voltage in the ground wire
- The evaporator temperature sensor is defective
Was Sie tun können
- 1Read and note the fault code, clear it and road test to check whether it returns
- 2Check that the evaporator temperature is reasonable. If the car has cooled down with the climate off, it should roughly match the outside air
- 3If you have a diagnostic tool: follow the evaporator temperature in live data and check that the value is reasonable
- 4Check that the connectors to the sensor are free from oxidation and sit firmly
- 5Disconnect the connector and use a multimeter to check that the signal and ground wires have no contact with voltage
Symptome, die Sie bemerken können3
- No cooling from the A/C system
- The A/C compressor will not start, or only starts now and then
- Irregular cooling from the A/C system
