Module Replacement Guide (RF-Hub, Pcm, BCM, ESL)

The Immobilizer Component Replacement guide has been modified to list all of the Immobilizer related procedures, found in wiTECH, listed by priority. Starting with the most important procedure first, along with an "X" to indicate when it is necessary to run this procedure.

BCM replacement Flash the ECM/PCM if the Spare Part is supplied without software Transfer secret key to ESL / ECM RFH replacement BCM replacement (first phase, at a certain point will be asked to configure the RFH, at that point run the RFH replacement, after the RFH replacement and the Disable Fobiks procedures run again the BCM replacement procedure in order to complete the BCM configuration) RFH replacement RFH replacement BCM replacement BCM replacement Flash the ECM/PCM if the Spare Part is supplied without software RFH replacement
2 Disable KEYs/FOBIKs (Only if the procedure did not run automatically after the RFH replacement procedure. All FOBIKs should be present, but the FOBIKs not present at this time will be temporarily disabled.
