Hva betyr feilkoden?
The CPM keeps an eye on the heater's coolant temperature through the overheat sensor. To protect the heater, the fuel pump stops when the sensor trips. The fault is set by an open circuit in the wiring to the overheat sensor, and the heater's function is blocked.
Mulige årsaker
- Coolant level too low
- Electrical fault
- Damaged coolant pump
- Damaged cooling circuit
- Damaged overheat sensor
Hva du kan gjøre
- 1Check the coolant level and mixture, and top up with the correct mixture if needed
- 2Check all wiring to the overheat sensor visually for damage and make sure the insulation is intact
- 3Use a multimeter to check that the cable to the sensor is continuous along its length; a break means the cable must be repaired or replaced
- 4Check that the coolant hoses are not deformed
- 5If the fault remains, have a workshop check the coolant pump, the cooling circuit and the sensor
