Hva betyr feilkoden?
Although the code is named component fault, it applies when the temperature sensors inside the electric rear axle drive control module (IEM) indicate a temperature that is too low. The causes are a too-low reading of the module's own temperature, or an internal fault in the voltage converter (ISC). Electric propulsion is then not possible.
Mulige årsaker
- The module's own internal temperature reads too low
- Internal fault in the voltage converter (ISC)
Hva du kan gjøre
- 1If you have a diagnostic tool: read the temperature values of the IEM in live data and see whether any of them is low compared with the others
- 2Have a workshop check the electric rear axle drive control module and the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 3Do not carry out any work on the control module yourself
- 4After the repair, read out the fault codes and check that the code is not stored again
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.
