Was bedeutet der Fehlercode?

The high voltage generator control module (IGM) monitors its internal components and related functions. The code is stored when the current sensors fail to calibrate automatically. The fault is only checked once the combustion engine is running.

Mögliche Ursachen

The control module was restarted while ERAD was not stationary
Software fault in the IGM
Internal fault inside the ISC voltage converter

Was Sie tun können

1Read out, clear the code and road test with the engine running to see whether it returns
2Have a workshop check whether the IGM needs recalibrating and whether new software is available for the control module
3If the fault returns, have a workshop check the ISC voltage converter
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
