Question: I have onstar on my 02 dmax(inactive) do i still need to pull the onstar fuse to program my computer? thanks

Pull that fuse PEVOMAN, thats so onstar can't interupt you during installation.

Hey guys you have to pull the on-star fuse when I install my hypertech I just bought it and I haven't put it in yet !!!

The only problem is when I bought the truck no owners manual and I don't really fell like pulling fuses till I find it could you guys help ?

2002 d-max cc, s/b, lt 3" lift 285 mud tires

read the manual that came with the hypertech and it shows which fuse to pull and it's location.

My question was...why would i need to pull the fuse if i have no on current subscription to Onstar, even though i do have a Onstar in this truck? It's a pain in the butt to have to get under the hood & pull the correct fuse everytime i want to change tuner settings

For what it's worth, I tried loading the Hypertech WITH the onstar fuses pulled and it wouldn't load. Went to about 55%, quite programming and told me to call Hypertech. Tried it a few more times like this, same thing. Put the fuses back in and tried it, it worked like a charm. I, too, have not activated my Onstar yet.
