When i try to read my 05 duramax i have a tcm read fail. I took screen shot of the read fail loc numbers. I have unpluged my brake controller and also took the onstar fuse out. what do i need to do so i can read my vcm.
Thanks,
Chase

do you have a piggyback tuner of any sort? That seems to be an issue when reading...might wanna unplug it.
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
No i do not.
You don't want to be posting your serial and appkey's here.
What are your laptop specs?
We got this guy Not Sure, ...
Thanks for the info on serial and appkey's.
I just tried my buddy's brand new hw lab top and the samething happened. It read the first time, but then i tried to read the vcm again and it loc b/c of the tcm.
Pull the radio fuse.
Thanks, I will try that when I get home

I tried pulling the radio fuse. So far i have pulled the onstar, radio, radio amp, and brake controller. It will let me read the vcm the first time i try, but when i try to read it again it will not let me read it. I get the tcm loc codes. I have tried after i read the vcm cranking the truck up and letting it run then reading the vcm. It still will not read it and loc on tcm error codes.
thanks for your help,

You have to turn the key off for 30 seconds and let everything reset between read/writes on these things.
