Hva betyr feilkoden?
Although the code is named circuit resistance out of range, it concerns the inductance difference between the electromagnetic coils in the electric rear axle (ERAD). The electric rear axle drive control module (IEM) compares the coils while driving in gear D or R and sets the code when the difference becomes too large. The fault lies in the electric rear axle. Electric propulsion is then not possible.
Mulige årsaker
- The electric rear axle (ERAD) is damaged
- Internal fault in the electric rear axle (ERAD)
Hva du kan gjøre
- 1Have a workshop check the electric rear axle, since the fault lies in it. High voltage systems may only be handled by qualified personnel
- 2Do not carry out any work on the electric rear axle or its wiring yourself
- 3If you have a diagnostic tool: read the IEM fault codes after a drive in gear D or R and see whether the code is set again
- 4After the repair, check that the code is not stored again and that electric propulsion works
Symptomer du kan merke4
- Warning window with a warning symbol and text message
- PURE: the drive mode disengages automatically or is unavailable
- AWD: the drive mode disengages automatically or is unavailable
- HYBRID: the combustion engine is active 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
