Programming Replacement Passlock TM Sensor, BCM, or PCM
IMPORTANT:
Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.
Important:
- The body control module (BCM) must be programmed with the proper RPO configurations before performing learn procedures. Refer to BODY CONTROL MODULE (BCM) PROGRAMMING/RPO CONFIGURATION in Body Control System.
- If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn passlockTM 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.
