WARNING: This page is about a different car, the 2005 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
- The body control module (BCM) must be programmed with the proper regular production operation (RPO) configurations before performing learn procedures. SeeBody Control Module Programming and Setup in Programming and Setup.
- If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn Passlock(tm) sensor data code immediately. The existing powertrain control module (PCM) however, must learn the new fuel continue password when the BCM is replaced.
- If replacing a PCM with a GM 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.
