Hva betyr feilkoden?
The electric rear axle drive control module (IEM) compares the calculated torque with the power and speed. If they do not agree, the code is set while driving in gear D or R. The causes are lost calibration, a control module that is not calibrated, a software fault, or an internal fault in the voltage converter (ISC). Electric propulsion is then not possible.
Mulige årsaker
- Lost calibration
- The control module is not calibrated
- 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 calibrate the electric rear axle drive control module and check that the calibration passes. High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: compare the calculated torque in live data with speed and power during a drive in gear D or R
- 3Have a workshop download new software to the IEM if the fault remains
- 4After the repair, check that the code is not stored again while driving in gear D or R
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.
