Disregard Dzug 2's ignorant answer. I presume that you are talking about the warning index scanner used by immigration to find out if there is a 'hit' on your passport. If so, then it doesnt matter whether there is a chip or not on your passport as information is checked using your name, date of birth, passport number and country code.
Anyway, only major offences would appear under WI. In addition, if this was just a caution then as it was not a conviction and therefore does not need to be declared (I am not sure if any kind of offence at all should be declared to the U.S. authorities when applying for a visa). In any event, if there HAD been a conviction, it would be spent after 5 years. I think the fountain of all knowledge, Buenchico, will be able to assist you better. Im not usually the one answering the questions, I ask them!
But as I work with visas all the time...
