Hva betyr feilkoden?
The CPM has registered a signal that is too high on the cable to the combustion fan. The fault may be caused by a short circuit to supply voltage in the cable. The heater cannot be activated until the code has been cleared.
Mulige årsaker
- The cable between the CPM and the combustion fan is shorted to supply voltage
Hva du kan gjøre
- 1Clear the code and start the heater again; if the code returns, the fault is still present
- 2If you have a diagnostic tool, activate the combustion fan and listen for a buzzing sound; if there is none, the fault is probably permanent
- 3Disconnect the connector at the heater and check that it is secure and free from oxidation
- 4Use a multimeter to check that the cable to the combustion fan 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 cable and the combustion fan
Symptomer du kan merke2

Hva feilen kan påvirke1
