Was bedeutet der Fehlercode?
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.

Was Sie tun können

- 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
