Was bedeutet der Fehlercode?

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.

Mögliche Ursachen

One of the three temperature sensors inside the IGM is damaged
Internal fault inside the ISC voltage converter

Was Sie tun können

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

Symptome, die Sie bemerken können5

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

Was der Fehler beeinflussen kann1

The high voltage battery cannot be charged by the combustion engine
