What does this fault code mean?
The high voltage generator control module (IGM) monitors the starter generator ISG. The code is stored when the speed of the ISG exceeds a limit after the combustion engine has been over-revved. The fault is only checked once the combustion engine is running.
Possible causes
- The combustion engine's rpm is too high
- The starter generator ISG is damaged
What you can do
- 1Read out and note the code, clear it and run the engine to see whether it returns
- 2Avoid running the engine at too high an rpm, since this is one of the causes listed
- 3Have a workshop check the starter generator ISG, since it may be damaged
- 4Do not work on the starter generator ISG or the high voltage system yourself; have a workshop carry out those checks
Symptoms you may notice5
- 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
What the fault can affect1
