I have a 2021 Yukon xl and was wondering if anyone has tried swapping out the switches to a 2022 for the hard button for the camera. I know it’s a long shot, but any chance it’s doable?

asked a dealer and they had no idea.

Man, this forum doesn't get as much help as the truck side of things.

Anyways, update on my question.  IT IS PLUG AND PLAY for my 2021 Yukon XL Denali (build date May 2021).

 
Several people were saying it was not possible and just to trade up to a 2022 model, but I didn't want to lose any features I currently have. This was by far the best $70 I have spent on this vehicle.
 
There are 25 part numbers for the switch with camera, so you will need to figure out which is correct for your vehicle based on RPO's. Parts guy at the second dealership I went to (first was not interested in helping me) was willing to print out the list for me to figure out which it was as he could not find it based on a VIN I gave (I have attached the part numbers pages so hopefully others can find their's easier). 
Mine was an ultimate:
UHX: Lane departure
JHD: Hill Descent
UD5: parking sensor
KL9: Auto start/stop
UV2: 360 camera.
Z88: GMC
 
Other RPO's listed:
NSS: no start / stop
X88: Chevy
 
You can find your RPO code on the driver's side door jamb and scan it with your phone camera to read it.
 
Once you get the part, it literally took less than 10 minutes. 
  1. Popped off the 2 panels: Do the bottom left of the kick panel first, then do the side piece. 
  2. remove 7 mm screw that holds the trim piece with the switch.
  3. pull straight out on the trim piece with the switch (4 retainer clips, see picture).
  4. remove clip but first using small flat head to slide red locking piece out (to the right in the picture) and then flip green piece down and it will release the harness.
  5. Remove switch from trim piece with small flathead to release clip at each corner.
  6. Install new switch and then put everything back!

Very informative posts. I have a 2021 high country suburban with the same switch setup as you. Ordered part # 84786497, I will report back with another data point after install. I also plan on installing an auto stop eliminator at the same time. 
 

FYI, for anyone with a non Denali Yukon or Tahoe/Suburban the switch panel disassembly/assembly is covered in a video on the auto stop eliminator web site.

Installed my switch panel today, everything works as advertised. It’s nice not having to navigate the touch screen to get the 360 cameras up. Thanks peterlawl84 for sharing the information to make the swap possible.

Thank you for all your help on this! We have an 2wd Duramax Yukon SLT that does not have Hill Descent Control. I ended up ordering the part number 84786496, and I also paired it with the auto stop eliminator and everything works great.

My 2021 Suburban controls do not have the hill descent button.

It looks like b0hr found the right part to substitute to get the camera function.

 

But, if I add the button assembly that peterlawl84 used, will I also get a working descent button?

Is that plug and play also?

b0hr, what is the auto stop eliminator and where do you get it?

I can guess what it does but what does it look like and how is it installed?

You will not gain descent control. thats a separate module.  This has been confirmed by others that tried to use the same button I did on their vehicle without it.

Another successful installation. 

As noted by b0hr above I used part number 84786496 for my 2021 4WD Suburban LT.

I also installed the TRL Autostop Eliminator at the same time.

Everything works great!

OMG this has been driving me crazy ('21 Yukon Denali). Stumbled upon this thread and just ordered the upgraded part (84786497). Can't wait to have a hard cam button - thank you, all!

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
