Hva betyr feilkoden?
The 15 feed is the supply that follows the ignition, and the CEM controls the output signal to its relay. The code is stored when the output to the relay coil has contact with supply voltage. The engine may then have difficulty starting or not start at all, and the fault shows up sometimes or always.
Mulige årsaker
- The cable has contact with supply voltage
- The relay for the 15 feed in the engine compartment relay and fuse box is damaged
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 that the relay for the 15 feed is seated firmly in the relay and fuse box and is not corroded
- 3Look for chafing on the cable to the relay
- 4Use a multimeter to check whether the cable to the relay coil has voltage when the ignition is off
- 5If the fault remains after these checks, have a workshop with diagnostic equipment check the relay and the wiring
Symptomer du kan merke2
- Engine fails to start
- Engine does not start, either sometimes or always
Hva feilen kan påvirke3
- The output switches off in the driving cycle in which the fault is detected
- If the fault remains, the output switches off permanently after 100 driving cycles
- Clearing the fault codes resets the output
