    TPMS and Torque app

    Current Gear is: PID 22199A Name Current Gear Gauge Gear Equation A Units Min Max Header Auto This works on both my Tahoe and my Escalade, so I would expect it will work for you. I have also worked out Selected Gear (PRND321) on the Tahoe. I haven't tested it on anything else, so...

    Do you mean current gear or selected gear?

    Fuel efficiency drop in newer models ?

    My Escalade with the 6.2L also can routinely get 20-22 mpg on the highway, and the BEST MPG which has never been reset since new currently shows 28.0 mpg (50 mile window). Seems like the OPs results should be better, I would not expect the heavier LWB to be that much less.

    Tinted front windows - Can it get removed?

    The windshield has been replaced, but that is a Pilkington. They are an OEM supplier to GM, so I wouldn't be concerned about the quality. Not sure what to make of the frosted appearance, but it looks to me like it is an intentional pattern, like someone had it done for appearances.

    TPMS and Torque app

    Still here, but I don't play around with PIDs so much these days. I have figured out most of the ones I wanted for the Tahoe. I drive a 2021 Escalade most of the time now and most of those PIDs don't work on it. GM has changed them in the newer CANBUS and Global-B protocols. I figured out...

    2023 suburban RST aux battery tray GM # 84817040

    I suspect the interior trim with the access panel is a police package specific part.

    2023 suburban RST aux battery tray GM # 84817040

    Found the PPV documentation, here's a link to it: https://capfleet.com/wp-content/uploads/2021/06/2021-Police-Tahoe-9C1-Municipal-Specification-Guidev3.pdf Aux battery is on page 25. On closer inspection it does appear to be a conventional lead-acid battery, but seems to me that it would have...

    2023 suburban RST aux battery tray GM # 84817040

    I have looked into the aux battery placement on the current generation, and from what I can tell, it is mounted behind the driver's side panel in the rear cargo area where the subwoofer would normally be. I found some information showing this in the PPV documentation. It appears that the aux...

    LED dome lights not working properly...

    They are only needed for the lights that can be turned on individually, like the reading lights. When all of the interior lights turn on, such as when opening the doors or using the switch on the dash, even the LEDs draw enough current to activate the circuit. But you will need a capacitor for...

    LED dome lights not working properly...

    Was able to get a picture today. The capacitor is soldered to one bulb tab and the resistor to the other, then they are connected together. Make sure that the positive side for the capacitor is connected to the 12V side and the negative side is connected to ground. It doesn't really matter...

    LED dome lights not working properly...

    Well, my phone decided it's not taking pictures today, but here is a schematic of what I did to mine. It includes the capacitor and resistor values. The 15kΩ resistor across the capacitor sets the fade out time. The larger it is, the slower it fades out. Without it the LED has to drain the...

    SD Card Removed - and I did it! (Yikes)

    Yes, I believe so. There are instructions for installation there as well. I think it explains why mine was corrupted when I removed it. The instructions say to turn everything off and wait ten minutes before removing the card. I know everything was turned off when I removed mine, but I don't...

    SD Card Removed - and I did it! (Yikes)

    This is the website I was on, https://gmnavdisc.navigation.com/models/Catalog/Catalog_Cadillac_Escalade/en_US/GMNA/USD If you click on 2021 you get the pricing. This is for the Escalade, but if you select GMC and Yukon using the menu at the upper right, the price is the same for a 2021 Yukon...

    SD Card Removed - and I did it! (Yikes)

    Just looked up the cost of a map update SD card on GM's website. It looks like they are $150.

    SD Card Removed - and I did it! (Yikes)

    I think you may need to get a new Navigation SD card. I popped it out and put it back in shortly after getting my Escalade, and everything was turned off at the time. Nav would not work after that. I don't remember exactly what the message was, but the dealer had to get a new card for it to...

    New Escalade IQ EV

    I figure this will keep the value of my 2021 up, being the last generation of gas Escalades, given that I think a lot of people won't want an electric model. That is, unless Cadillac continues the gas model along side the electric. As an aside, personally I think the current Escalade is much...

    Cabin air filter

    Both filter types are correct (I have used both). Because of the firewall sloping toward the rear as it meets the floor pan, there isn't enough room to slide the filter straight in. GM deals with this by cutting notches in the sides so the filter can fold and then straighten out once it is...

    How do thieves circumvent the passlock theft deterrent?

    This is FAR from the first time it was posted on the internet how this is done, it's been well known, especially by thieves for nearly two decades. That's why they target them. Quite a few other vehicles of that era had the same vulnerability. Of course you shouldn't post it if it was some...

    Consumer reports rates 2022 Yukon 2/100 in Reliability

    But the point that I was trying to make is that I see more GMT800s than Expeditions or Sequoias regardless of the year. What I was attempting to say is how reliable the GM SUVs are by pointing out how many are still in service.

    Yes, but their report was claiming that fenders rusted through.

    Consumer reports rates 2022 Yukon 2/100 in Reliability

    My 2021 has been very reliable with 34k miles so far. My only complaints have been with a couple of software updates. As for the full-size GM SUVs in general, I see many more GMT800s still on the road than any other brand/year SUV, and they're 20 years old now. Mine has 220k miles with no...

    ELM327 OBD Bluetooth Diagnostic Module That Can Scan Other Modules Such As ABS, BCM, TCM?

    You could try BlueDriver, their dongle is ~$120 and the software is a free download. I have one in addition to my other scanners, and it seems to be able to scan the other modules in the car. I have used it on GM, Lexus and Acura.

    So now GM is going to start charging us for software updates??

    I agree, the first thing I have always done with a new install of Windows is to turn off automatic updates. GM's poor documentation of changes that an update addresses got me into this mess to begin with. I thought that it might fix an intermittent, but rare, problem that I had since the...

    New OTA update

    You can go into the system menu and check for updates, but in my experience it won't find it. However, a few days after I received that message the update popped up again and I was able to install it then. I am getting pretty leary of updates though since the latest one broke my back up camera...
