What does this fault code mean?
An internal memory fault has occurred in the electric rear axle drive control module (IEM). The fault is set with the ignition on once the control module's test has started. Although the code is named rotor sensor, it concerns the memory in the IEM. The cause lies in the voltage converter (ISC). Electric propulsion is then not possible.
Possible causes
- Internal fault in the voltage converter (ISC)
What you can do
- 1Have a workshop read the fault codes in the IEM and check the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 2Do not carry out any work on the high voltage system yourself
- 3If you have a diagnostic tool: read the fault codes with the ignition on and see whether the code is still there
- 4After the repair, check that the code is not stored again
Symptoms you may notice4
- 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
What the fault can affect2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
