Programming Replacement Passlock™ Sensor, BCM, or PCM
2004 Oldsmobile Bravada AWDSECTION Programming Replacement Passlock™ Sensor, BCM, or PCM
WARNING: This page is about a different car, the 2003 Saturn Vue. 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 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 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.
