Co oznacza ten kod błędu?
The code is set when the link from the engine control module to the coolant pump relay has a break. The module then cannot drive the coolant pump properly, and the pump may be switched off, which can affect temperature control and the parking heater.
Możliwe przyczyny
- Loose connection or oxidation in the connector
- Open circuit in the signal ground wire
- Damaged coolant pump relay
- Damaged pump
- Short circuit or open circuit in the wiring to the pump
Co możesz zrobić
- 1Check that the relevant fuses are intact and that the connectors at the coolant pump relay are fully seated and free from oxidation
- 2With a multimeter, check that the wire between the engine control module and the relay has no break
- 3Also check that the electric water pump and its wiring are intact
- 4If the connectors and wiring are sound, the relay or pump is probably damaged; have a workshop replace the faulty part
Objawy, które możesz zauważyć4
- Uneven temperature in the cabin
- HYBRID drive mode is used all the time or too often, with the combustion engine running
- The parking heater does not work
- Text window with a warning symbol and text message
Na co może wpływać usterka3
- The coolant pump is switched off
- The coolant valves are kept open
- In cold outdoor weather the coolant pump keeps running
