Hva betyr feilkoden?
The high voltage generator control module (IGM) measures the temperature of its high voltage transistors with three sensors built into the control module. The code indicates that the control module is too hot, because one or more of the sensors show a high temperature. The fault is only checked once the test has started at ignition on.
Mulige årsaker
- Too high internal temperature in the control module
- Internal fault inside the ISC voltage converter
Hva du kan gjøre
- 1Read out and note the code, clear it and start the car
- 2If you have diagnostic equipment: look at the IGM temperature values in live data and see whether any of them is clearly higher than the others
- 3Have a workshop check the control module's internal temperature and the ISC voltage converter
- 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.
