Hva betyr feilkoden?
The fault is present now: the engine control module (ECM) has registered too high a signal from the signal cable to the A/C relay. The fault remains, and the A/C system does not work, until the cause has been put right.
Mulige årsaker
- Signal cable is in contact with voltage
- Break in the supply to the relay
- Damaged A/C relay
Hva du kan gjøre
- 1Use a multimeter to check whether the signal cable is in contact with voltage when the ignition is on
- 2Look for chafed cables at the relay
- 3Check that the supply to the relay has no break
- 4With a diagnostic tool: read the A/C relay signal in live data when the A/C is switched on
- 5If you find no fault, have a workshop replace the A/C relay
Symptomer du kan merke1
- The A/C system does not work
