I'm trying to help a friend out that is a little technologically impared. He doesn't have a computer, but he does have a 88 celica turbo all-trac thats throwing codes. I told him I'd be nice and look at some Toyota forums and find out what a code 54 is (the local dealerships tell him it doesn't exist but I saw it blink the code). After checking out Toyota forums, I realized what a great place HT is. Those people don't know sh*#! I figured I'd give a try here just in case there is some one who might know or could me a good link.
