Programming Theft Deterrent System Components: Notes

NOTE: The Body Control Module (BCM) must be programmed with the proper RPO configurations before performing learn procedures. See PROGRAMMING in appropriate BODY CONTROL MODULES article in ACCESSORIES & EQUIPMENT.
NOTE: If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the BCM must be programmed with proper RPO configurations before performing learn procedures. If replacing BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn Passlock® sensor data code immediately. The existing PCM however, must learn the new fuel continue password when BCM is replaced.
NOTE: If replacing a PCM with a replacement part, after programming, these modules will learn incoming fuel continue password immediately upon receipt of a password message. Once a password message is received and a password is learned, a learn procedure must be performed to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password and will require a learn procedure after programming to learn current vehicle's password.

There are two available methods to perform the programming procedure: A 10 minutes procedure which requires a Tech 2® and a techline terminal and a 30 minutes procedure which does not require the use of any tools. Use these procedures after replacing:
