Took the truck out just now. The streets are wet from an all night rain. As soon as I got a little tire spin, the truck started saying Traction Control Off and Stabilitrak Off. It then went into Limp mode. I first disconnected the battery to reset, and took it out again. Same thing happened. As soon as I spun the tires, I got the same messages and it went into Limp Mode. This time I hooked up my Scangauge II and got a code of B2AAA. I was able to clear the code but I cannot find any info on what this code stands for. A lot of other people have gotten the code but nobody that posts knows exactly what it is. Any ideas?

If you google it, it seems a bunch of people have got this code using a scangage. It is not an OBD11 code, No one has figured it out. But you already know that.

Not to dig up an old post, but does anybody have any more info on this code. My dad's CEL came on today in his 2008 GMC Sierra and it had this B2AAA code, I pulled it using my scangauge II. I cleared it and drove around the block and it didn't come back on, so we'll see what happens. If it comes back on I'm going to try a different code reader and see what happens.

 

Note, he never had any prior issue like the original poster, just the code

I just returned my new ScanGauge II to AutoZone. They didn't 'like it' but they DID refund my $'s. Didn't like it.

 

I got that same code (B2AAA) which, of course, made no sense to me. She tried to tell me that the ScanGauge sufisticated (wow, spellchecker doesn't catch that one) that it reads the 'GM specific' code... but nowhere can I find what it IS! Seems to mean different things to different folks. (vehicles)

Two orher code readers (cheapone's too) read it as P0672... bad #2 glow Plug. I replaced it, reset the code and it disappeared for good. Prior to replacing the GP, and a reset and it would come right back on.

 

My truck is an '07 (late model) with the LMM diesel.

I am looking into the same issue and so far I have come up with is that it is a sensor issue with the engine reading that cold air is getting inside, ie the engine isnt warm enough. still doing some more digging as it has been doing this and tried some other things first, battery and plugs, now it may be the ECM or the throttle control sensor. I will check these out and post what changes occur.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
