1. The body control module (BCM) must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. Ensure that the following conditions exist in order to prepare for BCM programming:

•	The battery is fully charged.

•	The ignition switch is in the ON position.

•	The data link connector (DLC) is accessible.

•	All disconnected modules and devices are reconnected before programming.

Important: When programming the BCM, be sure to select "Replace" not "Replace and Reprogram" when starting the programming event.

2. To setup a new BCM, use the Tech 2 in conjunction with the Saturn Service Stall System . Refer to Service Programming System (SPS) .
3. If the BCM fails to accept the program, perform the following steps:

•	Inspect all BCM connections.

•	Verify that the scan tool has the latest software version.

Important:  If any module or device listed is replaced, programming of the module must be done prior to performing the Passlock Learn procedure.

Perform the Learn Procedure if any of the following components have been replaced:

Refer to Immobilizer System Component Programming for the proper procedure.

Important: After programming, perform the following to avoid future misdiagnosis:

1. Turn the ignition OFF for 10 seconds.
2. Connect the scan tool to the data link connector.
3. Turn the ignition ON with the engine OFF.
4. Use the scan tool in order to retrieve history DTCs from all modules.
5. Clear all history DTCs.
