Programming Replacement Passlock™ Sensor, BCM, or PCM
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2007 GMC Savana Special, 2007 GMC Savana Camper Special, 2007 GMC Savana, 2007 Chevrolet RV Cutaway, and 2007 Chevrolet Cutaway. 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 option (RPO) configurations before performing learn procedures. Refer to Body Control Module Programming and Setup .
- If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn Passlock™ 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 vehicles fuel continue password and will require a learn procedure after programming to learn the current vehicle password.
