What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[gooffeyguy]

have you tired asking the dealer if they would be kind enough to assist with tpms? using there tool, or maybe be slick and go in for a oil change and tire rotation and let them deal with it, lol
mine would probably at least give it a shot in the service drive with there tool real quick without charging me for it.

does the wireless key fob work to lock and unlock? I think the tpms and key fob function run thru the same module

He stated it has no key fob, it's manual locks

The most obvious solution?! No lol. I just don’t have the time to take it anywhere. That’s why I spend so much time tinkering on my own. And no the van is manual windows/locks. So no fob to test

The transmission shop I used, really more of a custom tuning place, uses HPTuners. He said he couldn't retune it if an AutoCal had already done it. He was afraid it would brick the ECM. He said he would re-do the tune (disable AFM, rear O2s) after the dealer is done re-flashing. It'll cost me about the same as BB would charge to do it (again).

It doesn’t matter if it was tuned with the Autocal. Once the tune is installed in an ECM or TCM, any tuning software can pull a copy of that tune which is then saved as, say, an HPT file if that’s what is being used , then modified by HPT and then flashed. I did this with my BBP tune on my 02. I pulled a copy, modified my trans tune to not report codes related to a 2-3 solenoid issue I was having because my trans builder said their builds don’t even use that solenoid. Then I flashed the modified tune and voila no more problem. I think that guy just wants money imo. He should know that.

I don't think that's always the case. Sometimes, hpt can't read or compute a tune that was done with efi live. I say this based off years ago information so things could've changed. The way the programs work or values they see, aren't always the same. I could definitely be wrong, but it was a problem back when I first got hpt

have you tried disconnecting the battery ground for about 10 minutes? then try again

That’s not what I’ve learned. As soon as the tune is flashed into the ECM/ TCM it’s in its native format or else the vehicle can’t read it. Then you just download the files from your vehicle into your tuning software at which time it’s converted into a HPT file or whatever you’re using. As long as you don’t try to download the file from one tuning suite to another directly, you’re fine. It’s the same as downloading your stock tune and then modifying it. I did it- my BBP tune (EFI Live) is now modified by my HPT suite.

Good to know

So the A/C compressor from Rock Auto has an extra connector on the rear cap that I presume is for a high pressure cutoff switch. But my original doesn’t have that extra connector and instead has the high pressure cutoff on the line a few inches from the compressor itself. Apart from that, the compressor is a perfect fit.

I’m guessing that I can still use this compressor and simply not connect anything to the rear connector and instead plug the compressor switch in like normal (has the same connector there as the original), and plug the 2nd connect into the connector on the line as it was with the original compressor. Anyone see any problem with this plan?

I don't know I always thought they had to be the same and this is the problem with buying compressors

replaced the passenger side mirror, mirror works fine but in the process the triangular trim piece broke a clip off and almost all the door panel clips broke off
so if you plan on pulling door panels off of a 10+ year old vehicle invest in some of these, gm wants about $8 each

Beat me to it. I was about to suggest adding up the ampacity of all the breakers in their home panel and seeing if that number exceeded their main breaker rating.

*EDIT* Aaaaand now I see @gooffeyguy beat me to that.


I should read the following posts before replying

I was going to say the same thing and realized I’m 25 pages behind. I never get email alerts anymore so I never really catch up. Sigh.

Aha! One I can answer before somebody else does! I just did the AC system in my 02 and the compressor was like that- but there were instructions included that said exactly that. If your truck has the connector, plug it in. If it doesn’t, don’t worry about it. I guess some do, some don’t so they quit making 2 separate parts.

I haven’t done this specifically to test the TPMS. But I did have the battery disconnected last year for about a week when I was rebuilding the top end. So I guess that counts?

I can try that again tonight maybe

Woohoo! Thanks Mark!

Thanks, I needed that!

 

[Doubeleive]

Thanks, I needed that!

ya none of the ones at the auto parts store fit at all, they are all too small. I went to 3 stores and couldn't find anything that would work. bought 2 from the dealer and then ordered 12 more and searched the part number online, so the ones I ordered from the dealer are going get returned that was $140 including the $36 triangle trim piece.

and after all that I discover the freaking mirror cap is a slightly different shade of silver, but oh'well f-ik

 

[gooffeyguy]

So the door panel needs to be removed to replace the mirror on the GMT900's?

My gmt800 only needed the triangle piece removed. Mounting nuts and wire plugs all right there

 

[Charlie207]

it should go into learn mode and then eventually time out if nothing is synced, I think times out in like 2 minutes if no activity. same nbs, nnbs, k2

My Nissan winter wheels/TPMS don't sync with my Yukon, and just display the dash light after a few minutes, but nothing else.

There should have been an option to disable the TPMS alerts.

How did the world survive before Bluetooth and electromagnetic nannies?

Yes, the harness is clipped to the metal door skin inside in 3 locations and the harness plugs into the passenger door switch
you can disassemble it from the outside if you really wanted to if the mounting base was re used I previously took it apart twice repairing the broken folding gear.

I need the triangle too for the driver side.
