Hva betyr feilkoden?
Although the code is named incorrect response from the immobilizer control module, it applies when the IEM's electronic start interlock (immobilizer) code does not match the code in the central electronic module (CEM). The causes are software faults in the CEM or in the IEM. Electric propulsion is then not possible.
Mulige årsaker
- The CEM has a software fault
- Software fault in the electric rear axle drive control module (IEM)
Hva du kan gjøre
- 1Have a workshop download the latest software to the electric rear axle drive control module and check the software in the CEM. High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: read the fault codes in the CEM with the ignition on and see whether any other code is also set
- 3Do not carry out any work on the high voltage system yourself
- 4After the repair, check that the code is not stored again
Symptomer du kan merke4

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
