Before you can go to your web browser
you’re gonna run it as administrator acdelco website

log in
all right i came in earlier and purchased my one vin
so here’s where it changes completely um
go to view and add
well now before you can do this
there’s a new software Techline Connect
First time you’ll have to download it
takes quite a while
you’ll actually have to open the program
three different times for it to be
installed all the way
that’ll install
everything that you need to proceed it’s
kind of an all-in-one thing now
so once you’re here you’ll have this
launch as an admin
so you’ll launch it
the same way make sure you have internet connection wherever you’re at this will automatically connect to the internet
This is showing because i came up i came in here earlier and connected it with my vehicle
i’m gonna hook up the MDI
all right same deal you got the green light here

i’m choosing the MDI2 and see what happens
i think what i have is an mdi1 though

so we are at this part here we’re gonna click up at the top SPS2 which is the menu section we’re already in
select programming reprogram and then there’s a little green next
