Co oznacza ten kod błędu?
The high voltage generator control module (IGM) compares the calculated speed of the starter generator ISG with the measured speed. If the difference becomes too large, the code is stored. The fault is only checked while the combustion engine is running.
Możliwe przyczyny
- Software fault in the IGM
- Internal fault inside the ISC voltage converter
Co możesz zrobić
- 1Read out, clear the code and road test with the engine running to see whether it returns
- 2Have a workshop check whether new software is available for the IGM and install it if needed
- 3If the fault remains, 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
Objawy, które możesz zauważyć5
- 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
Na co może wpływać usterka1
- The high voltage battery cannot be charged by the combustion engine
