Was bedeutet der Fehlercode?

The high voltage generator control module (IGM) measures the temperature of its high voltage transistors with three temperature sensors built into the control module. The code is stored when the signals from these sensors fall outside the permitted range given how the starter generator ISG has been used. The fault is only checked once the test has started at ignition on.

Mögliche Ursachen

Air or leakage in the cooling system, or a low coolant level
Damaged cable or connection to the coolant pump
Damaged coolant pump
Software fault in the IGM
Software fault in the engine control module (ECM)
Internal fault inside the ISC voltage converter

Was Sie tun können

1Read out, clear the code, start the car and road test to see whether it returns
2Check the coolant level and look for leaks in the cooling system
3Have a workshop look over the cable and connector to the coolant pump for damage and make sure they are fully seated
4Have a workshop check the coolant pump and whether new software is available for the IGM and the engine control module
5The high voltage system may only be handled by a workshop; do not work on it yourself

Symptome, die Sie bemerken können5

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

Was der Fehler beeinflussen kann1

The high voltage battery cannot be charged by the combustion engine
