Mulige årsaker
- Short circuit from the control valve to supply voltage
Hva du kan gjøre

- 2Read off and clear the fault code, then test drive to see whether it returns
- 3Check that the connector at the control valve and at the control module are firmly seated and free from corrosion
- 4Use a multimeter to check that the cable to the control valve has no voltage to ground when it should not
- 5If the cable is intact: have a workshop with diagnostic equipment check the control valve
