Hva betyr feilkoden?
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.
Mulige årsaker
- Software fault in the electric rear axle drive control module (IEM)
- Internal fault in the voltage converter (ISC)
Hva du kan gjøre
- 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
Symptomer du kan merke4

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
