Hva betyr feilkoden?
The high voltage generator control module (IGM) measures the temperature in the starter generator ISG using a temperature sensor. The code is stored when the signal from the sensor is missing or too low. The fault is only checked once the test has started at ignition on.
Mulige årsaker
- Loose connections, contact resistance or oxidation in the terminals between the ISG and the voltage conversion unit ISC
- Short-circuit to ground in the signal cable
- Open-circuit in the signal cable
- The wiring between ISG and ISC is damaged
- The temperature sensor on the ISG is damaged
- Internal fault inside the ISC voltage converter
Hva du kan gjøre
- 1Read out, clear the code and road test to see whether it returns
- 2Have a workshop check the signal cable from the temperature sensor in the ISG to the ISC and its connections
- 3Have a workshop check the temperature sensor in the ISG, as it may be damaged
- 4Do not work on the wiring in the high voltage system yourself; have a workshop carry out those checks
Symptomer du kan merke5
- 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
Hva feilen kan påvirke2
- The starter generator ISG has reduced function
- Charging of the high voltage battery is reduced
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
