Hva betyr feilkoden?
The code indicates a short to ground in one of the transistors inside the electric rear axle drive control module (IEM). The control module monitors its internal components, and The cause lies in the voltage converter (ISC). Electric propulsion is then not possible.
Mulige årsaker
- Internal fault in the voltage converter (ISC)
Hva du kan gjøre
- 1If you have a diagnostic tool: read the IEM fault codes after a drive and check whether the code is set again
- 2Have a workshop check the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 3Do not carry out any work on the high voltage system yourself
- 4After the repair, check that the code is not stored again after a few drives
Symptomer du kan merke4
- 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
Hva feilen kan påvirke2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
