This is my personal vehicle I have tune several times. Recently my wife was driving in the vehicle shut off with the messages service to stabilitrack ,ABS and traction control light on. Vehicle and will not restart after attempting to wrap my stop turn back to vehicle it says unkown vehicle. When you read the vehicle it says unlicensed and offers to let you use credits to license it.
I almost did this but I noticed when you click the engine tap after read it is totally blank there's nothing in there. Transmation has data in it but diagnostic and engine are completely blank there's no fields know anything.
I fear the ECM is dead but since this happened 2 weeks after my last rat I can't really see how this would be up tied to that.
I am using the in PVI to with 4.0 to software on windows 7 and also tried a windows 10 laptop with the same result. I'm not sure where to turn.
I can purchase a used DCM that is matches exactly what I have but I'm being told that it can't be flashed in my car without having GM do it. It is a readable computer with a Vin number and everything but I'm being told there is no way to transfer it to my car.
If someone has any idea or any way to help me please I'll open all suggestions.
When I use my Alltel scanner I get the same error message u 1000 perminent connection with ECM lost.
Also if anyone knows a way toTransfer this EC into my car I'm willing to follow those instructions as well have just need to get my car backup running as it is my daily driver.
