2020 Silverado 1500 brake flush confusion.

[Dborch41]

I have the above truck (since new) and live in a humid environment, because of this I like to do a brake fluid flush on all my vehicles every few years. I've done this plenty of times before but this will be a first on my Silverado. I've done all the internet research but the info is quite inconsistent, some say it's just a simple bleed like any other brake system (as long as no air gets introduced), while others claim the the ABS has to be cycled with a diagnostic scanner among several other additional steps. I understand this is necessary if a component is replaced and air gets in the system upstream of the ABS module, but is all that required for a simple fluid exchange?

I have both a Motive pressure bleeder and a basic vacuum type, I'll likely use the Motive if I can get a proper adapter. I also have an XTOOL Anyscan A30D Bidirectional Scan Tool that I'm pretty sure will activate the ABS module (it did on my Nissan Frontier), but I'd like to avoid that if necessary.

Thanks as always for any input.

Use the motive bleeder and do as usual. Sure, there will probably be some in the ABS module that doesn’t get replaced. After the process go to a gravel parking lot and activate abs a couple of times. Thats how I’ve always handled this “activate ABS module stuff”

There's a small gravel parking lot just down the block from me that I've used just for that purpose. My wife's daily is a 2014 Nissan Frontier, a truck with a reputation for softish brakes. It's also fussy about consumer-grade code scanners and their ability to communicate with the ABS. I finally found one that did, but I still had to take a few trips to that little parking lot for an "ops check".
