Hva betyr feilkoden?
Once the contactors close, voltage in the HV system should climb. The code is set when that climb in circuit A is too slow, which may be caused by an open circuit in the high voltage cable in the circuit.
Mulige årsaker
- The high voltage cable in the circuit has an open circuit
Hva du kan gjøre
- 1Read and note the fault code, clear it and road test to check whether it returns
- 2Have a workshop check visible damage to the high voltage cable sheathing, such as chafing or pinch marks
- 3Have a workshop check the high voltage cable in the circuit for an open circuit
- 4The high voltage system should only be handled by qualified personnel, so have a workshop carry out all work on the battery and other high voltage parts
Symptomer du kan merke4
- Yellow warning symbol and message in the display
- Charging of the high voltage battery stops or works poorly, especially while driving
- Drive modes PURE, SAVE and AWD disengage automatically or cannot be selected
- Low voltage in the battery or a dead battery
Hva feilen kan påvirke3
- Charging with the combustion engine is not possible
- Charging through brake energy recovery is not possible
- Electric propulsion is not possible
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
