Hva betyr feilkoden?
The CPM has logged a glow plug signal that reads too high. The cause may be the cable between the CPM and the glow plug being shorted to supply voltage, or a damaged glow plug. The heater cannot be activated until the fault code has been cleared.
Mulige årsaker
- The cable between the CPM and the glow plug is shorted to supply voltage
- Damaged glow plug
Hva du kan gjøre
- 1Clear the code and start the heater again; if the code returns, the fault is still present
- 2With a diagnostic tool, activate the glow plug: no rise in temperature points to a permanent fault, a rise to an intermittent one
- 3Disconnect the connector in the heater and check that the contacts are secure and free from oxidation
- 4Use a multimeter to check that the cable to the glow plug carries no voltage when the heater is off; if it does, the cable is shorted to positive
- 5If the fault returns, have a workshop check the glow plug and the wiring
