Hva betyr feilkoden?
The high voltage generator control module (IGM) monitors its internal components and related functions. The code is stored when the calculated torque does not agree with the output and the speed. The fault is only checked once the combustion engine is running.
Mulige årsaker
- Lost calibration
- The control module is not calibrated
- Software fault in the IGM
- Internal fault inside the ISC voltage converter
Hva du kan gjøre
- 1Read out and clear the code, run the car with the engine on and see whether it returns
- 2Have a workshop check whether the IGM needs recalibrating, since the calibration may have been lost
- 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.
