Programming Replacement Passlock™ Sensor, BCM, or PCM

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 (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
  • 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 vehicle's fuel continue password and will require a learn procedure after programming to learn the current vehicle password.
