Co oznacza ten kod błędu?
The high voltage generator control module (IGM) monitors the internal components of the starter generator ISG, including its temperature sensor and position sensor. The code is stored when the signal from the temperature sensor is missing or too low, or when the signal from the position sensor is incorrect. The fault is only checked once the test has started at ignition on.
Możliwe przyczyny
- Loose connections, contact resistance or oxidation in the terminals between the ISG and the voltage conversion unit ISC
- Open circuit in the signal cable
- The signal cable is short-circuited to ground
- The wiring between ISG and ISC is damaged
- Internal fault in the starter generator ISG
- Internal fault inside the ISC voltage converter
Co możesz zrobić
- 1Read out, clear the code, start the car and see whether it returns
- 2Have a workshop check the signal cables between the ISG and the ISC and their connectors
- 3Do not work on the wiring to the ISG or the ISC yourself; have a workshop carry out those checks
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
