OBD 2 (96-2008) does not have that capability, older systems did up to the 1995 model year. You can buy a tester that does just codes on ebay for less than $40.00, live data stream testers are about double that.

Can a diagnostic connector on 1995 Toyota 4 runner be jumped over with jumper wire to get check engine codes?


There is probably a way to access codes by using a jumper and causing the engine checklight or an integral led to flash in groups. I can't say which pin or pins need jumping.

I suggest you ask the question of google and click on the youtube video.

How to repair if engine cannot race up when vehicle is running in Toyota Model KDN190R-CRPSYT vehicle?


If it is a Tercel or MR2, it is T and E1 terminals. Code 21 is main oxygen sensor signal fault. Code 51 is A/C signal on; DL contact off (in transmission shifter with diagnostic connector jumped). I have no idea what that 51 means.

How to check engine light codes on 1993 geo?


You will still have an OBD I system and will be able to retrieve codes by jumping the "A" and "B" terminals in the data connector. Turn the key to the "on" position and you should be able to count the flashed on the engine light itself.

1994 cutlass ciera s stops running after 20 minutes of driving.


The jumper goes into A & B, usually the top right two terminals. But check, in those years, GM was transitioning over to OBD-II, and they had some hybrid connectors that didn't match OBD-1 connectors. Leave it to GM for oddballing.

Can any tester be used to get data from a 1994 toyota camry other then an OBD1


In that year you should just be able to use a wire to connect terminal TE1 to E1, and count the blink pattern on the Check Engine light. See here p297

Do i need a scanner to get codes out of 1995 monte carlo or can i do it with a code key or paper clip it has ob 1


1995 was a change over year some of the cars had obd I connectors and some had the obd II as far as i know you will need some type of code reader if you have the new style connector even though the system is still obd I commiucation . If it is the old style connnector you can jump it with a paper clip and read the codes from the flashing engine light , Just so you know you can have your car scaned for codes from most local parts stores for free.. but do not think this is a diagnose of the problem and let them just sell you a part .

On some 1995 OBD 1 models with a 12-pin Data Link Connector, trouble codes can be accessed by connecting terminal B to terminal A with a jumper wire. With the key in on position, the codes can be read by watching the "service engine soon" light. HOWEVER, some models have a 16-pin DLC and you have to jump terminals 5 and 6 to get the trouble codes to flash.
