Just do the self test count the flashing CEL light make sure you know which pin is TE2 at the correct diagnostic port. If you really want to get into checking the computer buy yourself an old Toyota BOB (break out box).

@ Auto_Centric...Uhhh, I am NOT old! @ Stuck4747.....I would refrain from jumpering any wiring unless you know what you are doing. Jumper the wrong thing an POOF, you will let all the blue electrical smoke out and that is a bad thing. Check the fuse to see if it is blown preventing communication between a scanner and your vehicle.

first thing I'd do is replace the battery, then the cables..assuring solid power to things...both engine and chassis connections~ be sure the computer has solid ground too...we can take it from there...
