Hva betyr feilkoden?
The code is named high voltage, but the condition is that the signal wire to the coolant pump is shorted or has a break, or that the pump has another fault that prevents cooling. If the pump does not work, the high-voltage battery is not cooled.
Mulige årsaker
- Damaged pump
- Short circuit or break in the wiring to the pump
Hva du kan gjøre
- 1Read off the fault code with the ignition on and check whether it is still active
- 2Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 3Where possible, check on a test drive that HYBRID mode works normally, to establish the status of the fault
- 4Have a workshop check the pump and its wiring. Cooling of the hybrid system is a workshop task
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.
