BCM

2007 Hummer H3

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.
