Was bedeutet der Fehlercode?

The high voltage generator control module (IGM) lacks at least one signal from the battery energy control module (BECM), and the fault concerns communication on sensor CAN. Although the code is named invalid data, the signals are therefore missing. The fault is only checked once the test has started at ignition on.

Mögliche Ursachen

Oxidation, contact resistance or loose contacts at the connections to sensor CAN
Damaged cables on sensor CAN
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 and road test to see whether it returns
2Have a workshop check that the connectors to sensor CAN are fully engaged and free from corrosion
3Any codes stored in the control module that sends the signal should be dealt with first; have a workshop help with this
4If a control module has recently been replaced, check that it has the correct software; a replacement without new software can cause this code
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
