I've been putting it off for too long. I actually bought everything I needed to start flashing about 3 years ago. I started tinkering around, and had all the programs loaded in my laptop , but nothing came into the door needing flashed for a while. I then dropped my brandy newish shop laptop, and keeled it. That pissed me off, so I threw everything in my tool box and never looked at it again.
The main reason was it was just such a time suck to set everything up. I easily had an 8 hour day on tech lines, loading all the crap back into my new laptop this week.
I had a 2004 trailblazer come in with no 4wd. I traced it down to the control module, and decided to have a go at it. The reflash was easy peasy, it was all the setup that was the killer. I was thrilled to see the switch light up, and all functions normal again. Gm uses windows 7 and you have to use an outdated versions of Java to make the programs load. I am no techie, and would have never figured this out without tech help .
I have replaced these before, and always had a workaround for having to reflash them, and have found a workaround for nearly other electronic problem I have encountered here for the last 5 years, but finally said it was time to ramp up my diagnostic chops to the next level.
I'm done updating my snap on scanner, I am going to move more towards manufacture specific scan tools from now on out. Gonna be expensive, but that's the auto biz...
