Hva betyr feilkoden?

The high voltage generator control module (IGM) compares the calculated torque with the requested torque. If the difference becomes too large, the code is stored. The fault is only checked once the combustion engine is running.

Mulige årsaker

Software fault in the IGM
Internal fault inside the ISC voltage converter

Hva du kan gjøre

1Read out and clear the code, road test with the engine running and see whether it returns
2If you have diagnostic equipment: compare the calculated and requested torque in live data with the engine running; they should follow each other
3Have a workshop check whether new software is available for the IGM and install it if needed
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.
