Hva betyr feilkoden?
The CEM controls the output signal to the relay for the 15 feed. The code is stored when the output to the relay coil has an open circuit or is short-circuited to ground. The fault can cause the battery to discharge and the engine not to start.
Mulige årsaker
- The cable is short-circuited to ground
- Open circuit in the cable
Hva du kan gjøre
- 1Check that the relevant fuses are intact. Their locations are in the owner's manual or on the fuse box cover
- 2Check the battery's charge level and that the terminal connections are tight
- 3Look for chafing and pinch damage on the cable to the 15 feed relay
- 4Use a multimeter to check that the cable to the relay coil has no contact with ground (the body)
- 5Use a multimeter to check that the cable to the relay coil has no break in it
- 6If the fault returns, have a workshop with diagnostic equipment check the relay and the wiring
Symptomer du kan merke4
