I have a 1995 buick regal i bought a obd1 and obd2 scanner and it will not read codes is there a way of retreaving codes without taking it to a dealship

An OBD2 scanner can sometimes read an odd OBD1 code but there is no consistency. The OBD2 system is designed to be universal but only as far as faults that can affect exhaust emissions - other faults on the OBD2 system and the OBD1 system are manufacturer/model specific and require either dedicated diagnostic equipment or some very comprehensive software.

No the two system operating protocols are different.

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

If it has OBD1 for a diagnostic system you can get the trouble codes by making the check engine light flash.
If it has OBD2 you'll need a scanner or code reader. Most auto parts stores will check OBD2 for free in hopes of selling you some parts.
You can do an internet search for OBD1 codes and see if the connector plug looks like yours. If it does you can use a paper clip to jumper two connectors and make the warning light flash.
1994 and 1995 were cross-over years when the car companies switched from OBD1 to OBD2 so each model switched at a different time.

A 1995 model Buick should be OBD2 which would require a scanner or code reader. If it is an OBD1 system you can jumper two terminals on the test plug to make the warning light flash.

I suggest you use an OBDI code reader.

Underneath the steering wheel.

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.

Good Luck!

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.

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.
