I guessing you don't have JD9 rpo code. this is what I get for a. 2014 slt with a 5.3. let me know if it's to blurry to read. it looks kinda blah on my phone zoomed in.
Awesome, thanks.

I do have the JD9 RPO code.

interesting, I quickly Googled and looked like something about 17in brakes over some weight, I'll look and see what's different about the diagram with jd9

Without truly knowing for sure, my guess is that it has to do with my Yukon having the HD trailer package: KC4, K5L, GU6, G80, etc.. (basically all the external coolers, LSD, 3.42 gears). I don't really know.

man I see so many posts of automatic trannys going bad left and right. I thought the 4l60 had a bad rep when used hard, all these newer 6 and 10 speeds seem to lunch themselves at $8-10k a pop every 150k miles less. at least the poor. 4l60 lasted forever if just daily driven.

what happened to drivetrain reliability the last few generations across all these automakers.
this generation of trucks are getting older, your going to see more problems pop up especially from people that do not maintain things or are just learning that 160k is the point at which you either fix it or sell it.

maybe what I feel is old is just off by alot. 100k still feels like a new car to me.

Now that I have my shop vac again, I vacuumed the inside of the Yukon.
I hate having a dirty car.

I been itching to get a cordless vac. Every time I want to use it I dread the cord crap.

Pandora?

Is that something middle aged people do?

:hmmm2:
lol, it's free or paid, the free version plays a short add every 4-5 songs and you get like 4-5 free skips every hour or so I don't remember, I buy the pandora plus gift card and apply it to my account, so it's $58 for a year and there not tagging my bank every month, plus it's $5 cheaper than month to month anyway. then I have unlimited skips & replays, no ad's
that station has not failed to surprise me yet.

Per your diagram Fuse 61 (ABS 1 (40A)) is getting 12v, but fuse 9 (ABS 2 (25A)) is not getting any power.

The 25A fuse is good, and I swapped it with other good fuses, to rule it out. Neither side of the fuse gets power.

I don't think I have a fuse box diagram of what's going on inside. but I believe the top.part comes off and you can check inside?

Hahaha, so I'm an idiot to the Nth degree. For some reason there should be a 2nd 25A fuse right above the ABS fuse, but..... there wasn't. I have no idea when/how/why I pulled it, but I just swapped in the wiper 25A fuse and all the dash lights went away. And, now my Tech2 talks to all Chassis modules.
