Programming Theft Deterrent System Components: Notes

WARNING: This page is about a different car, the 2003 Pontiac Grand Am, 2003 Oldsmobile Alero, 2003 Chevrolet Monte Carlo, and 2003 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.

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:

The Passlock® Sensor.
The BCM.
The PCM.
