no i think that is the difference between OBD 1 or OBD 1.5 but not too sure OBD 2 did not start til 1996

OBD1.5 is the OBD 1 system with an OBD 2 plug.

thanks NIGHTHWK wasn't sure

OK. Can you point me to a pic describe what this plug would look like so I could figure out which I have? I am also searching this site for OBD-I error code listings in case that is what I have. I haven't found it yet, but I see Danthurs did an awesome job compiling OBD-IIs.

If you give me the numbers you get I can look them up. Look at the plug under your dash. Sorry not much info on OBD I most of us are II. Count the holes. If you have 12 holes you have OBD I if you have 16 holes you have ODB 1.5 or two. From the year of your car you will have obd I. Now what you have to do it take a paper clip or small jumper wire. Put the jumper in the top most right hole and the hole just to the left of it. (here if you have no metal connector in the next the first hole then you are obd 1.5 then you need to get the codes read somewhere) After you jump the connectors turn the key into the one position DO NOT start the car. When you do this the engine light will flash. With a pen and paper you will need to count. Count the first set of flashes then there will be a pause then count these flashes. This will be your first code. If more codes follow you will need to count those in the same manner. All the codes will be double digit no zeros or the first set being over 9 flashes. Once you count these flashes give us your numbers and I will be able to tell you what is up.

I must correct myself. OBD 1.5 is an OBD 2 system with an OBD 1 plug.

OK, the rain let up a little so I went to check.

I found the term block, pretty much dead center aligned w the steering wheel under the dash.

I have a 16-hole connection, the pins visible are represented with a solid dot, O'* are blank slots:

OOO••OO•
•OOOO•O•

According to the link, positions 4 & 5 on top row are grounds, 8 is 'Keyless Entry'.
Position 9 on second row is 'Serial Data (UART)', 14 is unknown and 16 is 'B+' whatever that is?

Not sure where to go from here-- will an OBD II sensor hook up -- or can I still do the terminal jumper thing another way (i.e. connecting 4 with 9 for the test)??

You need to get a scanner hooked up. I know pep boys, advanced, and auto zone do this for free. when you go in tell them you do have an obd II set up because they will just ask year the people there a trained to not care about years under 97.

I stopped at Autozone today, and the manager came out to my car in the parking lot and connected an electronic diagnostic tester for error codes from my 04 LeSaber. I am not sure if it is corporate policy to offer this, or if it is store manager discretion. Good luck.

If this is a '94, and it has the 16 pin connector, you CAN'T do flash codes....and I don't think this is OBD II...'94 might be a transistion year, and most scanners/code readers can't read those transition years....
