95 firebird obd2???????????????????

never had to pull codes from my car befor but ive been playing with some stuf like win aldl anyway made the cable and to my suprise it dose not work becuse my diag port is obd2 not obd1 what the hell is this all about the manu date is 03 \ 95 making it a 95 it should be obd1 right?

any one have any ideas or info or anything on this plez let me know :banghead:

did a little reserch on this and found that it is obd1 but it has a obd2 connector so what is the deal with this

My grand am is the same way, obd2 connector but obd1 system. GM got sick of people being able to pull codes with a paperclip so they changed the system, also added more diagnostic tools to it as well. To pull codes you either need a scanner or have a shop or parts store scan it.

Yes this is true. The government decided to step in and create OBDII, but it wasn't until 1996 it was required on all makes and models sold in the US. I own a scanner and tried to check a 95 chevrolet caprice and the scanner had an error. I researched it and found out that the connector's comm is UART, which is now stoneage speed connection rate. That is why even with the same connector, nothing seems to work. You can try the OBD1 scanners to see if that works. You can buy a cheap scanner that reads OBD1 AND OBD2 for $279.00 at AutoZone. hope you find what you are looking for :)

I work at an auto parts store, and I've seen this a lot. You have what some people call a "dummy plug", seems GM did this to several cars in the two years before they actually made the whole system OBDII. Ford did it too; I've got a co-worker with a '98 Cobra that has a dummy plug. Go to Advance Auto and tell them about it, they'll read your codes for free.
