If the body control module (BCM) is replaced, the following procedures must be performed in the following order:

1. BCM reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
2. Theft learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlock™ information automatically but the powertrain control module (PCM) must still learn the theft information from the BCM.

If the BCM is reprogrammed, the following procedures must be performed:

1. BCM reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
2. Theft learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

If the sensing and diagnostic module (SDM) is replaced, the following procedures must be performed in the following order:

1. BCM reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
2. Theft learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

If the Passlock™ sensor is replaced, perform the theft learn procedure. Refer to Programming Theft Deterrent System Components in Theft Deterrent.
