2002 Mazda Protege5 - OBDII communication failure

[r82148v]

Hey all..
I have a 2002 Mazda Protege 5.
I failed NJ state inspection for OBDII communication failure.

I checked the power pin (16). It was good with 12+
I checked pin (4) being the main ground and pin (5) being the signal ground.They are good too.

I tried disconnecting the battery for a while. That didn't help.
I checked every fuse I could find in the engine compartment and under the driver side dash with a volt meter. All is good.

The car runs perfect with no engine light on.

I have a simple OBD II scanner that keeps coming up ERR with KOEoff and with KOEon..
I tried using the scanner on a toyota and the scanner worked fine..

Would anyone have a solution as to what I can troubleshoot?
I read somewhere on the internet that a 2002 Mazda can either be OBDII or CAN....

Just for reference, the pins on the connector have wires in 4,5,7, 13 & 16

Thanks
Rick
