Hey guys, just picked up a U7192 9r11 for my 2006 Sierra VortecMax (1500 6.0L Auto).

I hooked it up and backed up my current setup perfectly but it would not load a new program. It would go 5% into it and stop with Unknown Error().

I have an ECM interface module for my alarm system, which I removed but it made no difference. The only other thing I can think of may be that I do not have the factory stereo system. I have an aftermarket CD player but do not have any ECM interface modules as I really dont like the chimes anyway.

Any information would be greatly appreciated.

Many times the harnesses used to connect aftermarket stereos will cause these types of issues.

i have no fancy harness to connect to my stereo. I use a simple harness that allows me to use power and ground out of the factory harness. I use RCA's for running my amps and thats it. The only thing that I could see causing an issue would be the fact that I do not have the original stereo hooked up.

Nay changes to the factory harness can be a problem, Id look into disconnecting the stereo.

Can i just pull the fuse for it? Or should i put the original one back in?

Id rather you try disconnecting it.
It is the wiring on the bus that I am worried about.

this may be a dumb question...but under tool info my version is 9r11 but my hardware is unknown...is this normal?

Took another try at it this evening....I did not pull the stereo as I didn't have time. I pulled the Radio, Radio Amp and Info fuses as well as hooked up a battery charger and tried agian. This time it went through and said "Unable to read vehicle type(1)" when it was trying to put new program onto truck.

okay....unhooked aftermarket CD player...no change. Any ideas?

tried it again over the weekend with the deck out and it worked perfectly....not sure what I did the first time. Thanks a million for the info.

Awesome.
Glad to hear it.

did you ever figure out what the problem was cause i have the same problem and pulling my radio completely out doesnt help
