Erros when writing to one particular 06 Truck

I keep having trouble when trying to write to one particular truck. It's an 06 chevy and I have tuned other 06 chevys and gmc's and never had problems.
I get errors even with a non active test write in low speed mode. The Vcm voltage on the bottom of the screen reads 0.1V but the gauge reads 12+. I took the lap top out of his truck and put it in my 04 and loaded a file fine.

I have seen post that ask for the vcm info log is this it?

if the volatge reads 0.1V it means the write/testwrite did not complete correctly. You will have to disconnect the battery if you cannot complete the write.

Do NOT try a write entire.

It is most likely the Onstar or radio causing the problems (try pulling the fuses). It seems GM introduced another breed of even more stubborn accessories in 06 :mad:

Chris...

We disconnected the battery and it started. I'll try pulling the fuse.
