Was bedeutet der Fehlercode?

The A/C relay control signal reads too high. The ECM watches that signal and also monitors the A/C system and its parts. The code is set when the module finds a signal that is too high, or when the A/C coupling relay is shorted to ground.

Mögliche Ursachen

Signal wire shorted to supply voltage
Faulty A/C relay
Open circuit in the power supply
Connections to the A/C coupling relay shorted to ground

Was Sie tun können

1Check that the relevant fuses are intact
2With the ignition off, use a multimeter to check that the signal wire to the A/C relay is not shorted to supply voltage
3Look for chafed wires near the A/C relay that could be shorting to ground
4If you have diagnostic equipment, read the A/C relay control signal in live data with the A/C switched on and see whether it is too high
5If the wiring is intact but the fault remains, have a workshop check the A/C relay

Symptome, die Sie bemerken können2

The A/C system does not work
Temperature control or air conditioning does not work
