OBD II, didnt come out till late 96 ..so if your vehicle is a 97 or better then, you have this system, but since you have a 93, you shuld have a OBD I... But some repair shops still have that availiable, and they can reset it for you..Or you can try unhooking the battery for a few minutes and then go test drive it.. If the light comes back on, then you may have a problem somewhere...But if it doesnt, then it was just a glitch within the electrical system, an you'll be fine..Goodluck...
