Hva betyr feilkoden?
The combustion preheater module (CPM) has registered a signal from the overheat protection thermostat that is too high. The cause may be a short to supply voltage in the cable, a break, a damaged thermostat or poor contact. The heater cannot be activated until the fault code has been cleared.
Mulige årsaker
- The cable between the CPM and the overheat protection thermostat is shorted to supply voltage
- Break in the cable between the CPM and the overheat protection thermostat
- Damaged overheat protection thermostat
- Contact resistance, oxidation or loose connections
Hva du kan gjøre
- 1Clear the code and check whether it returns when the ignition is switched on
- 2Disconnect the connector at the overheat protection thermostat and check that the contacts are secure and free from oxidation
- 3Use a multimeter to check that the cable carries no voltage when the heater is off; if it does, the cable is shorted to positive
- 4Use a multimeter to check the cable is intact between the heater connector and the thermostat connector; a break means the cable must be replaced
- 5If the fault returns, have a workshop measure the thermostat resistance
Symptomer du kan merke1
