What does this fault code mean?
The code concerns internal electrical faults in the electric rear axle drive control module (IEM). It is set when one or more of the control module's internal components do not work, and According to the cause, the fault 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 electric rear axle drive control module and check the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 2Do not carry out any work inside the electric rear axle drive control module yourself
- 3If you have a diagnostic tool: note whether the code is set again after the car has been driven
- 4After the repair, check that electric propulsion works as normal
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
General guidance for car owners. Diagnosis on the car can point to a different cause.
