Passlock Learn Procedure




NOTE
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.


NOTE
All codes in the theft deterrent module must be cleared for a relearn.


NOTE
The Body Control Module (BCM) must be programmed with the proper RPO configurations before performing learn procedures. Refer to BCM Programming/RPO Configuration in Body Control System.


NOTE
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.


NOTE
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. Use these procedures after replacing:

    NOTE
    Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
