Programming Immobilizer System Components: Notes

IMPORTANT:
  • The body control module (BCM) must be programmed with the proper regular production option (RPO) configurations before performing learn procedures. See 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 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.
