Hva betyr feilkoden?

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

Mulige årsaker

Oxidation, contact resistance or loose contacts at the terminals to HS CAN or sensor CAN
Damaged cables on HS 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

Hva du kan gjøre

1Read out, clear the code and road test to see whether it returns
2Have a workshop check that the connectors on HS CAN and sensor CAN are fully engaged and free from corrosion
3Have a workshop check the cables on HS CAN and sensor CAN
4If a control module has been replaced without new software being loaded, that may be the cause; have a workshop check this
5Do not replace the central electronic module (CEM) for a CAN fault unless a workshop has found an internal fault in it
6The high voltage system may only be handled by a workshop; do not work on it yourself

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 påvirke1

The high voltage battery cannot be charged by the combustion engine
