Did you try accessing codes the old fashion way? Turn the key just till the dash lites come on, no further. Cycle the key on--off, on--off, on, then the check engine light starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

Also, check for voltage at pin 16 of datalink connector. Hot all the time.
