Thanks for all the good info & detail.so pretty much there's no good info out to be found on these trucks. and definitely not in one place.
scanners that go deep enough to show data and reset useful stuff aren't cheap or easy to find. the free auto parts store scan is mostly useless besides just giving you a code.
as for the codes...
P0BBD = "Hybrid Battery Pack Voltage Variation Exceeded" (usually one or more dead cells) P0AC4 is just a generic code for the Hybrid module telling the Engine module to turn on the yellow check engine light
pretty much anyone over 100k will see this at some point. seems shops don't get it, or people don't want to believe it's time for an expensive battery replacement. hopefully this helps.
the general thinking seems to be these trucks are much harder on the battery than the prius, which they are also used in. that or gm programming just doesn't take care of them well. I'll attach a screen cap from a diagnostic file posted on a different site, I'm sorry I forgot his screen name to credit him but I will try to go back and find it. but it basically shows if the cells are more than 1.5v difference between them for a certain amount of time it throws the code.
I've read that any more than 0.2v isn't great. 1v is hurt and by 1.5v or more the pack is trashed and your truck is probably driving like crap with the ac on and it feels like the tranny is bad or something related to it. I could be, but it's probably not. mpg are probably not great either.
so that lead me to make this post to try and get some of the pids needed to cheaply and simply see how your battery is doing easy to find, because shops seem to be all very bad with this stuff.
you need the app torque pro, it's 5$ android only I believe. 20$ obd2 Bluetooth adapter off Amazon. lots are bad ones but 2 seem to always be good. I'll try and link the ones I tried, both work. I used the Dr prius app website list to pick the known good ones. if it reads the hybrid stuff on a prius it will on ours too but it's the app that interprets all the data for you and none of it come pre loaded.
this is what most people buy..
Wireless Bluetooth Diagnostic OBD2 Scanner Car Code Reader and Scan Tool for All 1996 & Newer Vehicles ELM327 Compatible OBDII for Android Devices ONLY https://a.co/d/gKiDOaq
but this one worked for me too..
NEXAS Nexlink Car Motorcycles... https://www.amazon.com/dp/B08BPC179W?ref=ppx_pop_mob_ap_share
so that brings us to pids. mostly all the apps don't have much defined secondary stuff, so you gotta input it yourself. there's tons of YouTube videos of how to do that using this data. much easier to watch how then me trying to type. just search adding custom Pid to torque pro.
all this I have found in 20 different places around the net, some even here but mostly abandoned boards not used anymore. Facebook really killed message boards. I haven't got to the point I can sort thru a data stream and figure out the pids on my own. I'd love to learn of anyone wants to show how it's done.
for a short quick look, I've found the pids for max voltage cell and min voltage cell. that's pretty much all you'll need, it will show you best and worst pack no matter what order it's in but over all pack voltage is nice to know. current coming and going from the battery. the state of charge. I'll list those first. basically load those up, drive till the state of charge gets high enough to go into auto stop,(they say 70% but I can't get much past 60%) have the ac and stuff on to get around a 10amp draw from the battery and watch the min and max. if there's more than say 1v it's hurt. some wouldn't find 0.5 acceptable, but mine still ran OK around there. by 1.5v it's going to set the code on yours soon enough. mine will show as much as 2v on a hot day. it's bad enough even driving in M4 mode I can tell it's not happy. cool day no ac it still feels fine to me.
this is what you'll put into torque pro under settings, add pid
Max Battery Pack Voltage (Volts)
2240EB
A/10
Min Battery Pack Voltage (Volts)
2240EC
A/10
where the top line is for pid, use the 2240eb number. under equation use the A/10. everything else can stay blank.
do the same for these.

you only really need the pid number and the equation the rest are just more for the graphing and naming.
so for example this is the format you'll see, I'll use Hybrid Battery Current from above and plug it in like this.
Name.. Hybrid Battery Current.

Equation.. ((A*(100/20)+0)/100)

that should be enough to see what kinda shape your battery is in, or even one your thinking about buying on a dealer lot. it's common for prius guys use the Dr prius app to run battery test before they by one and negotiating price based on battery life left. sadly Dr prius app doesn't work on ours.
here's some other pids I've found for those with more patience and interest.

I don't think I can link to another board but it has probably come up in your search already where you can log you data, post it up and they will graph it out for you. but quick and dirty the min and max is nice.
I'll attach some screen caps of mine, I wish I could imbed them in order, but basically start of auto start, the amp load while cranking in neutral and ending. notice the voltage difference.
just stuff I have searched around for and helped me understand these trucks. my new battery is here, just waiting for time to install it.
I have a 2008 Tahoe Hybrid with 140,000 miles that thru a check engine light today and has some hesitation going out of EV and does not always drops to Auto-Stop, Checked codes with basic Harbor Freight OBD2 device and got P0BBD & P0AC4 dtcs.
Fear I am facing battery replacement or repair. Any suggestions on sources for replacements or repair shops? I am located in Tulsa, OK.
I will investigate the app you suggest. Any other suggestions or advice is appreciated.
