IMO I only take CK engine light to trusted dealer. (yes some dealers are wacked also) You may pay little more but they usually do it right??? Any tire and lub. place not the place to go for computer problems on car IMO. Especially if you know nothing about how it functions and they probably don't either??).
They could of made OBDU 2 or what ever system there up to now and what the call it with troubleshoot program that would tell you what's wrong, but the dealer or who ever wouldn't get couple hundred bucks connecting fees pulling the code malfunction and reset.
