IGM-B20101E - Electric Machine. General Electrical Failures. Circuit resistance out of range
System
Unbekanntes System / Herstellerspezifisch
Volvo-Modelle, für die dieser Fehlercode gilt
Gilt für folgende Modelle:
1 ModellV60 (2011–)
Modelle nach Baujahr und Motor anzeigen (2)
Was bedeutet der Fehlercode?
Although the code is named incorrect resistance, it concerns the difference in inductance between the electromagnetic coils in the starter generator ISG. The high voltage generator control module (IGM) monitors the internal components of the ISG. The fault is only checked while the combustion engine is running.
Mögliche Ursachen
- The starter generator ISG is damaged
- Internal fault inside the ISG starter generator
Was Sie tun können
- 1Read out, note and clear the code, then road test to see whether it returns
- 2Have a workshop with diagnostic equipment check the starter generator ISG, since it may be damaged
- 3Do not work on the starter generator ISG or the high voltage system yourself; have a workshop carry out those checks
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
