Was bedeutet der Fehlercode?

The electric rear axle drive control module (IEM) calculates the torque in two processors and compares the results. If they do not agree in range and precision, the code is set while driving in gear D or R. The fault sits in the control module, and it concerns a safety function of the rear axle drive. Electric propulsion is then not possible.

Mögliche Ursachen

Software fault in the electric rear axle drive control module (IEM)
Internal fault in the voltage converter (ISC)

Was Sie tun können

1Have a workshop read the fault codes in the IEM and download new software if needed. High voltage systems may only be handled by qualified personnel
2Have a workshop check the voltage converter (ISC) if the fault remains after the software download
3Do not carry out any work on the high voltage system yourself
4After the repair, check that the code is not stored again while driving in gear D or R
