I bought a obd2 scanner that gives an error when trying to access codes and have taken it to autozone and they put the odb1 on it and it gives the same message.I have a check engine light on and it dies for no reason now and then so i thought the light may tell me why.It says under the hood OBD1 but it will not read it.I have read 95 is a could be either one.Does anyone know what it should be?Thanks for any help that you can give.

Re: 1995 900s OBD1 OBD2 ?
1995 is OBD 1. Saab became OBD 2 compliant in 1996. The error message may represent a communication problem between the device and the on board electonics, although this most often is manifested by failure of the reader to provide any message. Check your diagnostic port on the back side where the wires enter it. You will need to remove the two screws that secure it to the underside of the lower dash panel beneath the steering wheel to do this. Make sure that none of the pins have been pushed through the back side or have been loosened within the port. If it looks suspicious, try holding the wires securely into the port when connecting to the scanner. It may help to have an assistant who can experiment with various positions pushing against the backs of the pins while you try to get a secure connection. If this is not the problem, the scanner you purchased my employ the wrong communication standard for Saab cars, which is ISO 9141. There are three others out there in common use.

You can access them by going to the link, some late 1995 vehicles were OBD2, then you would have a diagnostic connector under the dash below the steering wheel, otherwise you do it under the hood (OBD1). FORD 1983 1995 OBD1 Decoder
The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
Okay, what you may have on your hands here is what has become known as an obd1.5 computer setup. Some of the 94's and 95's were made in anticipation of the switch to the obd2 set up. To determine if you fall in to this category locate your vehicle's computer. If it is under your hood in the engine compartment and you have two oxygen sensors and the port for your scanner fits an obd2 scanner then you have an obd2 system and your inability to link is either an electrical issue or something wrong with the computer itself.
If the computer is not in the engine compartment, you have one oxygen sensor, and the port for your scanner is rectangular you have an obd1 system.
If your computer is not in the engine compartment, you have one oxygen sensor and you have an obd2 scanner port you have an obd1.5.
Obd1 systems can be checked with an obd1 reader or much more easily with a paper clip or jumper wire. Just google something to effect of obd1 paper clip method. If there is still no communication once again you more than likely have an issue with your computer or electrical system.
If you have a true obd1.5 system do not fret there is still hope :) Yes there are some obd2 scanners that will work on these and there are some reportedly fancy obd1.5 code readers, however the easiest (and least expensive) way to pull the codes from this system is to use a modified version of the paper clip method. Instead of using your paper clip or jumper wires on terminals A&B, jump terminals 5&6.
Look at your scanner port. Count the terminals on the top row starting from the left. There should be connections in terminals 4, 5, and 6. Connect the jumper to terminals 5 and 6 and turn the key to the 'on' position (without turning the engine over). Your check engine light will flash. Each code will be two digits long and will flash three times (sort of like morse code). The first one will be a 1 and a 2, thus code 12. This code can be overlooked as it is just stating that the computer is being jumped. The codes that follow are the ones you should take note of.
These two digit codes correspond to the two digit obd1 codes. You can find their definitions on any number of websites. I personally prefer the haynes troublecode book though as it includes some make specific information.
Depending on what connector is in this vehicle being that some 1995 where OBD2 and some OBD1 it would be better to take it to your local Autozone or Advanceauto they pull codes for free and can give you a print out.
Your car is a 93 so its OBD1, 96 and newer are OBD2 so you can call your local autozone and see if they can read obd1 because most of them just read obd2 . If they do then they can hook a code reader to your car and retrieve all the codes for free! it beats any shops price for diagnostics.Thats a good place to start hope this helps and god bless.
the only way i know of getting the codes from your car is to find someone with a MAC or SNAPON scanner or buy a scanner from autozone and get the adapter for the obd1 to obd2 port. hope this helps you !!
you have a obd2 it has 16 data link connector you have to use scanner to get codes.now the obd1 system have 12 data link connectors..the top two at far right is where you put jumper wire to retrieve code.
