Yes.

However, I made my diagnosis with the fact that the PCM isn't communicating with your scan-tool at all.

Not usually. Most PCM'* are in the engine bay.

Hang on a sec though, are you SURE you have an OBD2 system? Your car is a 95. OBD2 wasn't standard until 1996.

Your scanner may be OBD2, but the computer in your car is OBD1.5. Only a couple of scanners out there can read the 1.5 systems. Probably your only option is to find someone that can read them, or take it to the dealer.
