Kia Sorento: Diagnosis Of Immobilizer Faults
| - |
Communication between the ECM and the SMARTRA.
|
| - |
Function of the SMARTRA and the transponder.
|
| - |
Data (stored in the ECM related to the immobilizer function.
|
The following table shows the assignment of immobilizer related faults
to each type:
