Hva betyr feilkoden?
The CPM has logged that the reading at the overheat thermostat or the coolant sensor has gone above the allowed level. The heater is deactivated and the code is set. The cause may be air or a leak in the cooling system, a damaged water pump, a damaged coolant temperature sensor or a damaged overheat protection thermostat.
Mulige årsaker
- Air or leakage in the cooling system
- Damaged water pump
- Damaged coolant temperature sensor
- Damaged overheat protection thermostat
Hva du kan gjøre
- 1Check the coolant hoses for damage and leaks, and look for air in the system
- 2If you have a diagnostic tool, activate the water pump and listen for a buzzing sound; if there is none, the fault is probably permanent
- 3If you have a diagnostic tool, read the temperatures at the overheat protection thermostat and the coolant temperature sensor and note the values for the workshop
- 4Have a workshop measure the resistance of the overheat protection thermostat and replace it if the values do not match
Symptomer du kan merke1

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
