Co oznacza ten kod błędu?
Although the code is named for software or calibration that is not approved, it concerns the signal to the A/C compressor's control valve. The ECM monitors the signal that operates the valve (solenoid), and an incorrect signal sets the code.
Możliwe przyczyny
- Signal wire shorted to supply voltage
- Signal wire shorted to ground
- Open circuit in the voltage supply
- Damaged control valve (solenoid)
Co możesz zrobić
- 1Check that the fuses are intact
- 2With the ignition on, use a multimeter to check the signal wires to the control valve for shorts to supply voltage, shorts to ground and open circuits
- 3Check the connector to the control valve on the A/C compressor for loose contact
- 4If you have diagnostic equipment, read the A/C control status in live data while the A/C is switched on and the compressor is working
- 5Tell the workshop if the car has received new software or calibration, and have it check the control module and the control valve
Objawy, które możesz zauważyć1
- The A/C system does not work
