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:
Immobilizer Related Faults | Fault types | Diagnostic codes
