Hva betyr feilkoden?
The code is named low fluid level, but the condition concerns the signal wire to the coolant pump, which is shorted or has a break, or another fault in the pump that prevents cooling.
Mulige årsaker
- Damaged pump
- Short circuit or break in the wiring to the pump
Hva du kan gjøre
- 1Check the coolant level when the engine is cold, as the code is named for a low fluid level
- 2Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 3Read off the fault code with the ignition on and check whether it is still active
- 4Have a workshop check the pump and its wiring, as cooling of the hybrid system is a workshop task
- 5Do not work on the hybrid system's wiring yourself
Symptomer du kan merke2
- The combustion engine is active in HYBRID mode more often than normal, or all the time
- A message and a warning symbol are shown in the display
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
