Help Needed - B1000 Symptom 35 Trouble Code - SOLVED

Great responses and recommendations, folks. Very much appreciated, and I'm learning a lot from all of you.

Since I am going to do the programming using TDS online option, versus installing software from the CD directly onto my computer, does it matter what the computer's operating system is, or if it is 64 bit versus 32 bit? My thought is that it no longer matters. Can you confirm my thought?

It will run on most operating systems, there’s a link to system requirements. The ones that say “unsupported” will still work but if you need technical help you’re out of luck.

Here’s the link to supported computers and systems. I was running it on Win7 32bit and when I ran into trouble because I had an aftermarket stereo which made the programming hang, I called support. They asked me what operating system I was running and then said I needed to upgrade to Win10 so they could log on remotely and see what was going on. So I did, and that’s when she could see I had a stereo that was causing the issue. It’s rare that you would run into an issue though. I believe others are running something other than Win10, guys?

Late to the party, funny I never was notified tho... hmm

probably better off without any wiseguy input from me anyhow Joseph... that and the fact that I don’t have a tech2.

I think the boys have you covered. Good luck.

I will say tho, before you go buying a new bcm, check those grounds and that fuse box as we all know these damn trucks hate to keep their grounds on and their fuse box’s from corroding.....

and the ecm connections/harness those have historically been a problem
other than that I have ran tds web with windows 7 32 & 64 bit, you just have to run all the java plug-in's it want's you to install.
might be advisable to buy the subscription and hook everything up and do some trial runs, you can run it all you want and back out anytime you want just to get the hang of it.
Tip: don't be moving wires/cables around, especially when doing calibrations, just put it all down and run it from the pc

TDS has some requirements on their website, still a Java based application so they'll prompt if there's an update needed there. My machine is 64 bit with Windows 10. 32 bit machines should be fine if memory serves.

Any updates @Joseph Garcia ?

Not yet. I've been working on some 'Honey do' list items. Hopefully, I'll be checking electrical connections out within the next few days.

Oh yeah, gotta take care of the important stuff first!

I was able to cut out some time from the honey-do list items late yesterday afternoon, and I checked the two connections to the ECM, as suggested. Once I figured out how to disconnect the connectors, I saw that all of the pins were clean and straight. So, I reconnected the two connectors, and I cleared the ECM trouble code using the Tech 2. I will be driving around a bit today running errands, and upon completion, I will see if the ECM trouble code re-appears. (I expect that it will re-appear.)

I also tried to find the BCM, as that was suggested as the next item to check out the connectors, but I could not find the BCM. Granted, I did not take a lot of time trying to find the BCM, but any recommendations on where the BCM is specifically located on my 07 Yukon XL Denali would be very much appreciated.

The BCM is on the left side above the parking brake area. You might have to remove the knee bolster or parking brake release. There was a plastic vent for the hvac in the way on my Silverado but it just pulled down. The BCM has 6 connectors iirc.
