Chevrolet: car not starting., chevy venture, optima battery

Question
I have a 2001 chevy venture WB edition and I put a new black top optima battery in it a few months ago and when i drove it, it was fine. A few weeks later it started shutting off while driving. The car would turn on when it wants to and after shutting it off, it won't turn back on. My brother tried jump starting it and all it did was say error on the radio. I Spoke to a dealer about it and he said that I need to bring it in for him to put a code in it. I have no way of bringing it in because It will not start. I here that i might need a code to reset the battery and i don't know what the code is. From Jordan Rubinstein

HI; well it is a bummer but it will have to be put on a meter to see what code pops up , as it could be any of a few 100s of things , it must be a small thing but it must be set in the computer with the meter or computer to find the trouble  ok
