Hva betyr feilkoden?

The engine control module drives the A/C compressor solenoid with a PWM signal through an internal power stage and compares the signal at its output. The code is stored when the signal is too low. Causes can be short circuits in the signal or ground wire, open circuits in the wiring or a damaged solenoid.

Mulige årsaker

Signal cable short-circuited to ground
Signal wire shorted to supply voltage
Ground wire shorted to supply voltage
Open circuit in the signal wire, ground wire or voltage supply
Damaged solenoid

Hva du kan gjøre

1If you have a diagnostic tool, activate the A/C compressor and read the solenoid control signal in live data
2Check that the relevant fuses are intact
3Check the connector at the A/C compressor for contact resistance and oxidation
4Use a multimeter to check that the signal and ground wires to the A/C compressor have no open circuit and are not shorted to each other, to ground or to plus
5If the fault remains, have a workshop with diagnostic equipment check the solenoid in the A/C compressor
