Yep! This should be a pin somewhere as @pgamboa really dives into all of this. Thanks for reposting the link!

Interesting information, thanks! I bought the ADC camera and it helped a bit but not dramatically so,

Sounds to me like normal fuel injectors firing off. Mine has been the same for over 5 years.

For the transmission I just went with the TSB. Chevrolet TSB 21-NA-199.pdf

Have you tried this option? ADC rear camera upgrade

I went with Borla Touring cat back exhaust. I thought about the ATAK but figured my neighbors might prefer a bit more quiet.

The Amp power steps are great! I've had them installed for quite some time. I do, however, have to replace the cushioned bump stops so I don't get a metal clunk when they deploy.

My truck didn't have a brake controller from factory so I had the dealer install this: Curt Spectrum trailer brake controller

Awesome you got it sorted! That's a new potential issue I'll have to mark in my book of issues. Thanks for the feedback.

Therefore, I presented the caveat about erasing codes and then check if the issue returns. I'm still leaning toward a BCM issue.

I've referred to this many times over the years and I've had zero issues after the installation. Also, it helped a friend of mine resolve transmission issues he was having with his 2018 GMC Sierra. Chevrolet TSB 21-NA-199.pdf

Yep, refer to Chevrolet TSB 21-NA-199.pdf

Seems to be a BCM issue. Have it scanned and checked for codes. Erase all faults and see if the issues return. If so, you might want to reach out to White Automotive for a BCM replacement.

I had tow mirrors installed by the dealer. They replaced the door harness (still have the original if anyone needs it). Later, I bought power fold tow mirrors from boost auto, no need for a harness but I did have to buy the folding switch setup for the door panel.

For what it's worth, Ive never experienced a bad HMI module. I've installed many of these as I upgraded to a navigation HMI. I still have two sitting on the shelf but they would have to programmed to your VIN which is what WAMS does. If you find that to be the issue, I can send you one but, again, @GTPprix would need to program it.

Cool! Pics?

I installed the Pedal Commander - no subscription required - and it worked great for a while, adjustable performance on throttle response from less to more. Also, I can control it via Bluetooth with my phone with the free app. One day, however, I got an error code thrown and went in to limp mode. I disconnected it, cleared the code and all was well. I left it in the truck and I'll try it out again soon to see if the issue repeats. Otherwise it did work well and it might have been my fault as some adjustments should be done with the caveat "DO NOT change modes while your foot is on the gas pedal" and I think I did one, or a few, adjustments on the fly. O_o *I do see they now have a subscription based ant-theft option*

OK, I did a bit of research, LKA came out in highly optioned trucks like an LTZ or a High Country in 2016. "It was introduced as part of the Enhanced Driver Alert Package, which was offered on high-trim models (such as the LTZ and High Country) starting in late 2015 for the 2016 model year production." Owning an LT1, I was never aware of this. One never knows what new things we can discover about these K2s.

Quite frankly, I had no idea a 2017 Silverado 1500 had lane keep assist. The first time I saw it it was when I rented a 2020 Silverado (before I bought mine) to pick up BMW parts.

I used the Holley F5 Flashpaq to tune mine out of AFM without an OBD dongle since I usually use it for the Autosync from BTDiesel which also allows AFM disable without being plugged in but does much more. The F5 Flashpaq let me tune for 91+ octane for a bit of a horsepower boost, though. it also has transmission shift point options but I'm not versed enough to make advantage of that option. Anyway, an OBD dongle isn't necessary with these options to retain AFM disable.

Is your battery good and pushing out proper voltage? Other than that, I hope you can get a reasonable solution.

I believe I bought them from Ready Lift but it's been awhile . For more information about a knuckle lift, here is an earlier post from here:

I went with MotoFab Ucas: Motofab 3" front and 2" rear lift with 35x12.5x18 BFG KO2s but still had to put on 1/2 inch spacers. I doubt you can get around this without a knuckle extension.

The alternator is checked by the BCM (maybe ECM?) and will change depending on the battery level. It's not unusual to see a variation from 12 volts to 14 volts. If you had a battery change, assure the charging ring is still in place.

When I start my truck on a warm day, the FANS turn on at high speed - I'm guessing you're meaning the radiator FANS? After a bit of driving, they turn off until they're needed. Generally, the FANS are there to cool the radiator until the coolant flow gets going. Just give the FANS a bit of time and let the ECM or BCM learn the process. Disconnecting the battery just resets the learning process.
