Reprogram Existing BCM

WARNING: This page is about a different car, the 2010 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

To program and setup an existing BCM, perform the following procedure:

With a scan tool, access the Service Programming System (SPS) and follow the on-screen instructions. Refer to Service Programming System (SPS) .
On the SPS Supported Controllers screen, select BCM Body Control Module - Programming and follow the on-screen instructions.

NOTE: When performing the Tire Pressure Monitor Sensor Learn during BCM setup, the J-46079 Tire Pressure Monitor Diagnostic Tool must be used to activate each tire pressure sensor.

On the SPS Supported Controllers screen, select BCM Body Control Module - Setup and follow the on-screen instructions.
Check the driver information center display for additional messages regarding further calibration instructions. If there are no addition driver information center instructions present, programming is complete.

If the BCM fails to accept the program, verify all scan tool and BCM connections are secure.

NOTE: After programming is completed, perform the following to avoid future misdiagnosis:

Turn the ignition OFF for 10 seconds.
Open and close the door.
Connect the scan tool to the data link connector.
Ignition ON, engine OFF.
With a scan tool, clear all DTCs from all control modules.
