Was bedeutet der Fehlercode?

The high voltage generator control module (IGM) communicates with the other control modules over the CAN bus. The code means that the signal configuration for the sensor CAN does not match, for example because the module is not intended for this particular car. The fault is only checked once the test has started at ignition on.

Mögliche Ursachen

Faulty configuration
Incorrect configuration ID; the module is meant for another car, for example a used module with different software or hardware
Software fault in the IGM
Software fault in the restraint system control module (SRS)

Was Sie tun können

1Read out and note the code, clear it and start the car to see whether it comes back
2If the control module has been replaced, check that it is intended for this particular car
3Have a workshop program the control module and download the latest software, since the module reports an internal fault that may have a software cause
4The 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 kann3

The control module switches itself off on the sensor CAN (bus-off) and stays off until the power supply has been disconnected
The high voltage battery cannot be charged by the combustion engine
When the power supply is reconnected, the control module tries to communicate again
