Hva betyr feilkoden?
The high voltage generator control module (IGM) measures the temperature of its high voltage transistors using three temperature sensors built into the control module. The code is stored when any of the sensors reports a signal that is too low. The fault is only checked once the test has started at ignition on.
Mulige årsaker
- One of the three temperature sensors inside the IGM is damaged
- 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 you have diagnostic equipment: follow the IGM temperature values in live data and see whether any sensor reads clearly lower than the others
- 3Have a workshop check the voltage conversion unit ISC, as it may also have an internal fault
- 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.
