Hva betyr feilkoden?
The high voltage generator control module (IGM) monitors its internal components and functions. The code is stored when the torque calculated in the control module's two processors does not agree in timing or precision. The fault is only checked while 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, clear the code and start the car to see whether it returns
- 2If the fault returns after a software update, have a workshop check the ISC voltage converter
- 3The 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.
