Hi, i need help with body control modulo of my 2007 H3.The turning lights no longer work. The car still goes but the turning light microchip and his basement Is fused.I'm looking for someone who can repair my bcm but it's very difficult in Italy to do that. I found a used bcm from another H3. Replacing my bcm with the other one the turning lights works again but the engine does not start. The key fob does not work too. I guess this Is due to a different code in someone microchip. Is It possibile to know the precise position of the microchips and their function on the bcm? Is there a diagram?Thanks

 

When you replace the BCM, you need to program it using a GM Tech II scanner.

 

And don't they have to be paired with the VIN number?

That is what the Tech II is for.
