Hey guys. I did this a while back.
I have to read the service engine soon code on a 1993 Toyota Corolla.
I know they have the diagnostic port under the hood- by the firewall.
In the past I used the jumper method.
I cant recall the exact ports to jump.
I think it was Tc and E1.... would this be correct?
I did a quick search online and im not getting any hits...
