'96 models of all brands went to a standardized system of fault codes and that is what the equipment used at auto parts stores read. For '95 and older, Chrysler made reading codes REAL easy, GM is almost as easy, and Fords are very difficult. They are easier to get the codes with a scanner, and those cost $2,000.00 - $6,000.00. That's why shops have to charge to read them. It's to help cover the cost of the equipment and the cost of updating them every year.
If you want to try to get the codes out yourself, try this:

It's a Mickey Mouse system, but if it works, it's free. You might also try asking at a community college that has an Automotive program. They won't do engine diagnostics if they are currently teaching Brakes or Air Conditioning, but if they're studying Engine Performance they may read the codes if they have time.
