Hva betyr feilkoden?
The CPM has registered that the signal wire to the glow plug is broken, so the signal is missing entirely. The cause may be a break in the wire or a damaged glow plug. The heater cannot be activated until the code has been cleared.
Mulige årsaker
- Open circuit in the cable between the CPM and the glow plug
- Damaged glow plug
Hva du kan gjøre
- 1Clear the code and try starting the heater again; if the code returns, the fault is still present
- 2If you have a diagnostic tool, activate the glow plug and see whether the heat rises; if it does not, the fault is probably permanent
- 3Disconnect the connector at the heater and check that the contacts are tight and free from oxidation
- 4Use a multimeter to check that the signal wire from the heater connector to the glow plug is intact; a break means the wire must be replaced
- 5If the fault returns, have a workshop check the glow plug and the wiring to the preheater module
