Linking the BCM to the PIM

With the Tech 2, perform the following procedures:

1. Replace the key fob transmitter for each of the vehicle's keys.
2. Connect the Tech 2 to the data link connector (DLC) and select: Diagnostic / Pontiac GTO/ Body / Body Control Module / Special Functions / Program Key Fobs, and follow the screen instructions to program the key fob transmitters. Refer to Transmitter Programming Transmitter Programming for further information.
3. When prompted, enter the security code located on the new BCM and follow the Tech 2 instructions. If a valid code is entered, the new BCM and key fobs will now be linked to each other. The key fobs will be write protected by the BCM and can never be link to another BCM.
4. After successfully programming the new key fobs, backup to Special Functions and select Link BCM to PIM and enter the new BCM security number. This will link the new BCM to the PIM and the security information in the PIM will change.

   Therefore, the PIM and the ECM will have to be linked. Perform a Vehicle Theft Deterrent relearn through SPS Programming. This will link the PIM to the ECM.
