Co oznacza ten kod błędu?
The fault is intermittent, meaning it comes and goes, and it concerns the signal wire from the A/C relay to the engine control module. The code is set when the wire is shorted to voltage, broken or shorted to ground, or if the relay is defective. The A/C system is then switched off.
Możliwe przyczyny
- Signal wire short-circuited to voltage
- Open circuit in the signal wire

- Signal wire short-circuited to ground
Co możesz zrobić
- 1Inspect the wire from the A/C relay for breaks, chafing and shorts to ground
- 2Check that the fuse for the A/C circuit is intact
- 3Use a multimeter to check that the wire is not shorted to voltage or ground and is not broken
- 4Have a diagnostic tool? Activate the A/C system and listen for the relay to click in
- 5If the wire is sound but the fault returns, have a workshop check the A/C relay
