Co oznacza ten kod błędu?
The code is stored when an internal fault has occurred in the microprocessor of the high voltage generator control module (IGM). Although the code is named blocked, it therefore applies to the microprocessor. The fault is only checked once the test has started at ignition on.
Możliwe przyczyny
- Software fault in the IGM
- Internal fault inside the ISC voltage converter
Co możesz zrobić
- 1Read out, clear the code and start the car to see whether it returns
- 2Have a workshop install new software for the control module if one is available
- 3If the fault remains, have a workshop check the IGM and 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
