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 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 RUN position.

•	The data link connector (DLC) is accessible.

2. Follow the instructions on the Techline Terminal and scan tool to program the BCM.
3. If the BCM fails to accept the program, perform the following steps:

•	Inspect all BCM connections.

•	Verify that the Techline Terminal and scan tool have the latest software version.

Requirements for Using Any Learn Procedure

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

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

Passlock Learn Procedure -- Using the Techline Terminal and the Scan Tool

Follow the instructions displayed on the Techline Terminal in Service Programming System (SPS) and the scan tool for this reprogramming procedure.

Auto Learn Passlock Procedure

1. Turn the ignition switch to the RUN position (NOT the CRANK position).
2. Turn the ignition switch to the CRANK position, then release to the RUN position (Do NOT start the vehicle).
3. Observe the security telltale for approximately 10 minutes.
4. After the ignition switch has been in the RUN position for approximately 10 minutes, the security telltale will transition from ON, then to OFF.
5. Repeat Steps #1 through #4 two more times.
6. After three consecutive cycles of the ignition switch are successfully completed, the vehicle will learn the new component on the next ignition cycle from the OFF position to the CRANK position, then to the RUN position. The vehicle will then start.
7. Clear the DTCs using a scan tool.

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.
