Thanks for your reply, Patrick. Briefly, I read that Auto-Zone performs this service for free. Upon taking the car to them. They said they could only read OBD II. Then I tried to order an OBD I reader and was told it only worked up to 1995, but not on 1995. The Toyota dealer did tell me to bring it in and they would read it, but they charge $85 and I was being frugal.
