Programming Theft Deterrent System Components

Important: 

• The body control module (BCM) must be programmed with the proper RPO configurations before performing learn procedures. Refer to BODY CONTROL MODULE (BCM) PROGRAMMING/RPO CONFIGURATION
• If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn the passkey data code immediately. The existing PCM however, must learn the new fuel continue password when the BCM is replaced.
• If replacing a PCM with a GM Service Parts Operations (SPO) replacement part, after programming, these modules will learn the 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 the current vehicle's password.

Conditions 

Use these procedures after replacing:

• BCM
• PCM
