This is a little video I made this morning while programming a replacement PCM (used) into a 2013 Grand Caravan. Sorry I wasn't too chatty first thing this morning.
I did this using the Maxisys Mini. It showed a failure during the programming cycle, and for some reason it does that frequently since I last updated (it used to do it flawlessly). I find that when it says it failed, all you need to do is hit the "Reset ECU" function and you're good to go. After you finish the programming cycle, make use you run a scan and clear DTC (diagnostic trouble codes).
Now if the customer supplied a brand spanking new PCM, this will NOT work. You need to flash with via J2534.

Just did 2003 Impala using TIS . In Body under Radio ,Relearn.No need for Vin from donor car.Have done a few Cadillac.They removed the feature on some newer but if you go back a few years on veh selection it sometimes works.
Customer said old radio was draining battery so they disconnected it 10 years ago. Someone wrote no sound on old radio .Now selling car .buys radio from junkyard pays me to unlock it . Guess what radio on ,no sound.Look under rear deck at amplifier . All unplugged ! Plug in Radio works .Old guy happy can sell car now Can’t drive anymore !
GM's a bunch of douchenozzles too. I got a GM parts buddy I've known for 20 years. He couldn't sell me a Tech2. Not wouldn't, couldn't. He did manage to sneak me the latest linear flash card though.

My post was not directed at you Ben. You would most likely be the recipient of such calls. It was more directed at the folks who bitch about the cost of something because they've seen the Chinese knockoff price on eBay but want the safety of buying it stateside.
Personally, I can't stand the tech calls about why something is not programming and find out they are using a $300 offshore programmer.
