Was bedeutet der Fehlercode?

The electric rear axle drive control module (IEM) monitors the high voltage system. The code indicates that the voltage in the high voltage system is below what the control module expects. Electric propulsion is then not possible.

Mögliche Ursachen

The high voltage battery is discharged
Loose contacts, contact resistance or oxidation where the high voltage battery meets the voltage converter (ISC)
The high voltage cable has a short to ground or a break
Damaged wiring between the high voltage battery and the ISC, or between the battery and the electric compressor control module (ACCM)
Internal fault in the electric compressor control module (ACCM)
Internal fault in the voltage converter (ISC) or in the high voltage battery

Was Sie tun können

1Have a workshop check the voltage of the high voltage battery and its connections to the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
2If you have a diagnostic tool: read the high voltage system voltage in live data and see whether it is lower than expected in gear P or N
3Do not carry out any work or measurements on the high voltage system yourself
4After the repair, check that the code is not stored again and that electric propulsion works

Symptome, die Sie bemerken können4

Text window and warning symbol with a text message
Drive mode PURE disengages automatically or is unavailable
Drive mode AWD disengages automatically or is unavailable
Drive mode HYBRID: the combustion engine runs all the time or too often

Was der Fehler beeinflussen kann2

Electric propulsion is not possible
Brake energy regeneration from the electric rear axle is not possible
