Computer reset

Everybody,
I wanted to reset my computer the other day in my truck because emissions are due. I disconnected the negative cable for about an hour & reconnected it. What do I need to do to get it to start receiving all the inputs again? I came across these posts while using Google to find some info. The truck is a '99 NBS 4x4 1/2 ton Silverado with 4.3/5 speed. I took it to AutoZone to hook up their scanner, but it was reading the inputs yet.

Thanks,
Chris

Re: Computer reset

I just drove it about 40-50 miles and it was ready, but on my way to emissions, it then threw a couple of codes. I'm trying to figure those out. The codes are P0171 & P0172. I'll start a new thread shortly for any suggestions.
