Hva betyr feilkoden?
The heater control module has registered too high a signal on the cable to the coolant pump. This points to a short to battery voltage or to a damaged pump. The heater cannot be started until the fault code has been erased.
Mulige årsaker
- The cable between the heater control module and the coolant pump is short-circuited to battery voltage
- Damaged coolant pump
Hva du kan gjøre
- 1With the ignition off, check the cable and connectors to the coolant pump for chafing, damage and corrosion.
- 2With the ignition off, use a multimeter: voltage on the pump cable means a short to positive.
- 3If you have a diagnostic tool: activate the water pump and listen for a buzzing sound. If it does not start, the fault is still present.
- 4Replace the coolant pump if it is damaged, or have a workshop do it.
- 5If the wiring is in good condition, have a workshop check the pump and the heater control module.
