As mentioned before, both of our cameras are misaligned. They still work, but the surround view is rather skewed on the sides. TNAT4 went to his dealer to get reprogramming done, and they were unable to do it without a code from GM. From what I understand, he would have had to buy another set of GM mirrors that come with a code, and there would still be no guarantee that they would be able to reprogram the mirrors I traded him. 

 

Maybe he can chime in at some point, but he was looking into having a custom shop fab up a mirror housing that would relocate his cameras to his previously calibrated locations. 

Yep, so I swapped pins 13 and 5 and I have full function of the DEZ smaller mirrors on my truck which came with the DRS mirrors factory.  The only difference side cameras are slightly skewed and now the puddle lights stay on at night because they’re connected to the pin for the parking lamps, which kinda looks cool.  I still haven’t decided if I’ll pay the custom shop the $700 they want to move the camera.

So I wanted to update my original post, but I couldn't figure out how to do it.   Anyway, after much research and with help and collaboration from TNT799 - We have figured out how to get the

Yes, if you get tow mirrors with that feature they will continue to work, plug and play.

Correct. You would have to buy tow mirrors from a 2020 HC 1500 (order them from the parts department.) Higher end tow mirrors with cams & blindspot warnings are not available on the accessory site

If you have time could you post a pic of the screen & the skewed view?

 

I'll try to go talk to a dealer next week & get a price for the tow mirrors & see what they say about correcting the surround view

This is what they look like in surround view. Notice how the yellow parking lines are not correct, and also my front cameras point a bit low, while the rears point high. That said, if I switch to the front/side view to view the front wheels, I still have a fairly good line of sight.

One other potential issue, we both lost our front and rear parking lines. You can see in my picture how there is an hourglass in the top left of the screen. However, they eventually came back for TNAT4, but mine have yet to reappear.

Okay so your truck came with power folding mirrors regular mirrors, and you swapped to power folding tow mirrors?  I'm looking to do the same thing, can you tell me everything that you did to get them to work? I see you swapped pins 5 and 13, did you also have to do the ones sam posted?  What worked immediately, did power fold and blind spot work plug and play?  

Thanks

Things that worked plug and play (I have a 2019, your 2020 may be different): power fold, heat, blind spot, cameras

Things that didn't work: rear facing light (no wire for it), turn signal/parking lamp (no wires for it), task lights (wire in wrong spot). 

 

Pins 5 and 13 are the task lights and puddle lamps on my 2019. On the 2020 mirrors those pins are parking lamps and task lights (tow mirrors don't have puddle lamps). By swapping those pins in my wiring harness, my task lights work normally, and the parking lamps turn on when my puddle lamps used to (when unlocking the truck in the dark, for example). 

 

At some point I'm going to create my own wiring harness (or maybe Boost will come out with one before then), and hopefully gain all the functions of the mirror. The lights really aren't a big deal to me at this point. The only reason I even swapped the pins was because I have the Boost harness that turns the task lights on with my high beams.

Okay awesome, the things you listed as plug and play are my main concerns, everything else I can work out later. 
 

I didn’t realize the 1500 tow mirrors didn’t have puddle lamps, the HD fully loaded tow mirrors do have them though.  It would be nice to be able to swap to them, and gain power extend too

Have you tried talking to WAMS, they do a lot of BCM reprogramming, maybe they could reprogram something to fix your cameras?  A lot of people use them for adding higher end model parts to their trucks

I've already reached out to WAMS, at least regarding my side of things. He said he is going to look into it.

How did yall swap the pins 13 and 5?  I tried to figure it out by lifting the while locking tab up and pulling on the wire, but it would not release.  I assume I'm doing something wrong.

They're fragile, but if you pull firmly with needle nosed pliers wrapped in electrical tape they'll come loose as long as the white locking tab is lifted.  I frayed one wire but wrapped it up and it works great.  I think I used a pointed tool to seat the pin back in once I swapped them, they're long and skinny

Dang, I pulled as hard as I was willing to try.  Guess I’ll try again next time I have the doors off

Use a pointed tool to pry up the lever, just insert and press down on the tab.

      I love my truck but

      Those  headrest speakers look fun! Standard panoramic roof on the AT4X might be a deal breaker for me unless I can delete it. Maybe I should just supercharge my truck and call it a day. We'll see what I think of all the new trucks when I see them in person.

      "Increase"?   You want to "increase" your turning radius?     What is your truck?  What kind of cab and bed do you have currently?  Is it stock?  Modified?  Lifted?

      Transmission Woes :-(

      By newdude · Posted

      OP's quote is parts and labor.  Not just parts.     The # you found isn't the right one.  But besides that, the right # is the same price within a couple bucks.  $5802.01.    Now, factor in labor and fluids.  Book time is 17.1 hours for a Colorado 8 speed.  At $200/hr for a dealer average rate, its $3420 just in labor.  We are already at $9222.  Fluid and other necessary items, there's your $400-500 more.      Also.  Your "discounted" transmission.  Which is 99% likely quoted off of GM Parts Direct as that's the MSRP I found on their site.    You failed to note the $597 in shipping charges.  So we are right back almost to MSRP.  $5794.  Oh.  AND, you better have the $4000 for the core charge which you'd have to pay and get refunded, AND you gotta pay to SHIP THE CORE BACK.    So now you'd have paid MORE to buy that one online yourself, even after you get your core refunded.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.
