Programming Replacement Passlock™ Sensor, BCM, or PCM

WARNING: This page is about a different car, the 2002 GMC Safari, 2002 Chevrolet Astro, 2001 GMC Safari, and 2001 Chevrolet Astro. 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 For 2001, see BODY CONTROL MODULE PROGRAMMING - REGULAR PRODUCTION OPTION CONFIGURATION . For 2002, see BODY CONTROL MODULES .
  • If replacing the 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 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.
