When you follow the instructions that are included in the box,you will most likely find the reason your computer burned up in the first place.
Thoroughly check the sensors and systems that the computer is controlling.
Alternator,cam sensor,
crank sensor etc.
When I removed my alternator on my dodge van to have it tested as per the instructions included in the computer box,
I found my coil right behind the alternator.
It was completely rusted out.
I replaced it with a high end replacement.
Checked all of my circuits with the help of my dodge service manual,which I bought from ebay and installed the rebuilt computer.van started right up no check engine lights.
Runs perfect, no bus gone.
Thanks
