Hva betyr feilkoden?
The angle sensor in the electric rear axle (ERAD) sends a signal that reads too high. The angle sensor gives the electric rear axle drive control module (IEM) information about the rotor position. The control module checks the calibrated limits through the sensor and sets the code while driving in gear D or R. Electric propulsion is then not possible.
Mulige årsaker
- Loose contacts, contact resistance or oxidation at the connections between the ERAD and the voltage converter (ISC)
- Open circuit in the signal cable
- Signal cable short-circuited to supply voltage
- Damaged wiring between the ERAD and the ISC
- Internal fault in the voltage converter (ISC)
Hva du kan gjøre
- 1Have a workshop check the signal wire and connectors between the electric rear axle and the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: read the rotor sensor value in live data during a drive in gear D or R
- 3Do not carry out any work on the wiring to the electric rear axle yourself
- 4After the repair, check that the code is not stored again while driving
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.
