Important:
• | The body control module (BCM) must be programmed with the proper RPO configurations before performing learn procedures. See Body Control Module (BCM) Programming/RPO Configuration . |
• | 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/VCM however, must learn the new fuel continue password when the BCM is replaced. |
• | If replacing a PCM/VCM 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/VCM 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. |
Use this procedure after replacing:
• | Passlock™ Sensor |
• | BCM |
• | PCM |
• | VCM |
Important: The vehicle learns the Passlockâ„¢ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
