OBD2 Doenst Connect

[Bluefire16]

I attempted to fix my OBD2 in the past, and nothing. All fuses are good...all my wires seemed good. Any ideas as to why it cannot connect? Or what to check?

I need to get this sorted out soon. Thanks!

What do you mean by obd2, you have to be specific. You mean the dlc? (data link connector) or the scan tool?

^^ Yes my dlc. I have tried to plug it in to read my codes and it doesnt. I have tried it several times, and with different readers so i think that my connection is somehow bad however.

Someone mentioned looking at a power wire? But i have no clue which one it would be.

Someone chime in please?

Pin 16 is your power supply, found a diagram from talk. Check the back of the interior driver side fuse box for corrosion, I had this problem when I first picked up my dsm.

Pin 16 power supply, pin 5 ground, and pin 7 to the ecu.

+1 on the rusted/corroded fusebox. Once that was replaced, it worked everytime.

I have checked several times my fuse box, simply for this and another time for actual blown fuses and again for my tranny. (its in limp mode...but i think i got that fixed) But thanks man, that pic helps!
