Hva betyr feilkoden?
The CPM has logged too wide a gap in temperature between the overheat thermostat and the temperature sensor. The heater is then deactivated and the code is set. The cause may be a damaged thermostat, sensor or water pump, or air or a leak in the cooling system.
Mulige årsaker
- Damaged overheat protection thermostat
- Damaged engine coolant temperature (ECT) sensor
- Air or leakage in the cooling system
- Damaged water pump
Hva du kan gjøre
- 1If any of CPM-5001, CPM-5101, CPM-3202 or CPM-3002 is also set, fix those first and then see whether this code returns
- 2Check the coolant hoses for damage and leaks
- 3If you have a diagnostic tool, activate the water pump and listen for a buzzing sound; if there is none, the pump is suspect
- 4Clear the code and start the heater again to see whether it comes back
- 5If the fault returns, have a workshop measure the resistance of the thermostat and the sensor
Symptomer du kan merke2
- Poor heating in the passenger compartment
- The parking heater does not work
Hva feilen kan påvirke2
- The heater is deactivated when the code is set
- If the heater is activated again, it makes a new start attempt
