When I scan through the OBD2 port it shows error. What would prevent the scan tool from communicating with my ECM/PCM?

Some years had ODB2 connectors with ODB1 programming. What year is your car?

96 is obd2. so check the wires on the rear of the DLC to make sure they all look right and ya dont have one pulled out. is the reader you are using getting power and just not reading or no power at all?

from what i've heard... the very first few of the 1996 models may have obd I.... not sure if i should believe that though

I'll check the wiring...the scanner has power it just reads connection error when scanned.

I thought all 96 and up were obd2, but what do I know. I'll check the wiring...the scanner has power it just reads connection error when scanned.

All the wiring is intact. There are six wires running to the port, is that correct? If it were an obd1 computer how would I go about identification? Also, my cigarette lighter wasn't hooked up for a few months, so I hooked it back up and unbolted my battery for a few min before scanning. Would that have anything to do with my issue?

I know for a fact it's obd2...
