yes, make sure the service writer states that on the work order. "all available bcm/pcm" updates, otherwise the tech won't know and it won't get done. The service writers are lackey and usually are too lazy to write details into the service order.
Do I need to do anything with this battery current sensor?

And then some. You cannot tell them too much to update for the money.

They should have like whole flash with latest updates . After digging thru the website there is a bunch to update calibrations since 2006. Witch causes false codes to come up that need updates . Makes me realize it should be first plan always make sure PCM updated would save alot of headaches .
Point being first code year ago was p 2135
But my grounds were bad that never came up again now p2108,p1516,u0107 came up twice. But before I seen the TSB I could of bought the throttle body$150 then the TAC $100 then I still got codes so I have pay another $100 for PCM update .. $350 it could of spin out control pretty easy .. Just because I never updated PCM . So PCM update is like the first thing to look at when dealing with crazy mystery codes popping up .[emoji15][emoji849] ( Good ground is still number one and a good battery )
That is my thought after looking at all them strange updates that say calibration updated . There is a bunch of them . I'm sure there the ones that pull mystery codes came up and it was really just software tuning errors. ( After you buy like couple sensors and a module and quart of dielectric grease checking connections )
Then we're at the mercy of the GMC Gods.lol

Yes, the General likes to keep us guessing.
When you get them done would you let us know what kind of pricing they get for full update programming? Ballpark? Just curious.

$79 looks like they just flashed.
PCM/VCM can anyone tell me details of these numbers ? It shifts better and smoother and for some reason a miss I had under load is now gone .[emoji849][emoji15] Worth the $79 do far .

looks like they are just calibration numbers, the part number may reference a tsb or something, who knows but looks like they did as requested.$79 looks like they just flashed.
