Hva betyr feilkoden?
The high voltage generator control module (IGM) monitors the high voltage system and its related functions. The code concerns a voltage that is too high in the high voltage system. The fault is only checked once the vehicle is in driving position with the combustion engine switched off.
Mulige årsaker
- The high voltage battery has overcharged
- Oxidation, contact resistance or loose contacts at the connections between the high voltage battery and the ISC or the electric compressor control module (ACCM)
- Damaged wiring between the high voltage battery and the ISC or the ACCM
- Internal fault inside the electric compressor control module (ACCM)
- Internal fault inside the ISC voltage converter
- Internal fault in the high voltage battery
Hva du kan gjøre
- 1Read out, clear the code, start the car and see whether it returns
- 2Have a workshop check the high voltage battery, since it may be overcharged or have an internal fault
- 3Have a workshop check the connections and cables between the high voltage battery, the ISC and the ACCM
- 4The high voltage system may only be handled by a workshop; do not work on it yourself
Symptomer du kan merke5
- Warning symbol and text message in the display
- Warning about power supply problems from the alternator and charge regulator
- Charging of the high voltage battery while driving is absent, reduced or not working correctly
- High voltage battery is discharged or charges poorly
- HYBRID drive mode: the combustion engine is active all the time or too often
Hva feilen kan påvirke1
- The high voltage battery cannot be charged by the combustion engine
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
