Co oznacza ten kod błędu?
Although the name points to the supervision software, the code applies when the phase current sensor readings disagree too much with one another. The high voltage generator control module (IGM) keeps an eye on the voltage and current feed to the starter generator ISG. The fault is only checked once the combustion engine is running.
Możliwe przyczyny
- Oxidation, contact resistance or loose contacts at the connections between the ISG and the ISC
- A short circuit from the high voltage cable to ground
- Break in the high voltage cable
- Wiring between the ISG and the ISC is damaged
- Internal fault inside the ISG starter generator
- 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 the cabling and connections between the ISG and the ISC
- 3If the cabling is in good condition, have a workshop check the starter generator ISG 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
