Computer problem
2007 Hummer H3 6 cyl All Wheel Drive Manual

When replacing you BCM and Cluster, the cluster locks out and the car will not start.
Since the BCM network is GM Class 2 (J1850) does anyone know the un lock code to send?
Thanks - Mike

Here is the information for programming and setup of the BCM. To my knowledge it requires a gm techline terminal for programming, but I am a dealer technician.
Body Control Module Programming and Setup
The procedures below are designed to set-up the body control module (BCM) correctly during BCM related service. Before you start, read these procedures carefully and completely.

Important: The following procedures must be followed: Programming the BCM
Learning the restraints ID
Programming Theft Deterrent System Components
Program Key Fobs
Program Tire Pressure Monitoring (TPM) System
Programming the BCM
Important: After the procedure is completed, the personalization settings of the BCM are set to a default setting. Inform the customer that the personalization must be set again.

Perform BCM special function " Request BCM Info. For SPS", then follow the instructions on the screen. Refer to Service Programming System (SPS) for more information.

Learning the Restraints ID
Perform BCM special function " Setup SDM Serial Number in BCM", then follow the instructions on the screen.

Programming Theft Deterrent System Components
Perform BCM special function " Request VTD Info. For SPS", then follow the instructions on the screen. Refer to Programming Theft Deterrent System Components.

Program Key Fobs
Refer to Transmitter Programming for the proper procedure.

Program Tire Pressure (TPM) System
Refer to Tire Pressure Monitor System Configuration for the proper procedure.

Important: After programming, perform the following to avoid future misdiagnosis: Turn the ignition OFF for 10 seconds.
Connect the scan tool to the data link connector.
Turn the ignition ON, with the engine OFF.
Use the scan tool in order to retrieve history DTCs from all modules.
Clear all history DTCs.
