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.

Where is the diagnostic port located on an isuzu trooper 1995 V6 model


You can get the check engine light codes yourself on 1985-94 Isuzu vehicles by using a jumper wire between terminal pins 1 and 3 or A and B in the diagnostic connector. This diagnostic connector can be located anywhere from the driver side kick panel, passenger kick panel and sometimes at the center console. When using A and B terminal pins, getting the codes is similar to GM vehicles. Once the jumper wire is connected, turn your key on and read the codes being flashed in the dash panel.

See Figures 1 and 2
Listings of the trouble for the various engine control system covered in this manual are located in this section. Remember that a code only points to the faulty circuit, NOT necessarily to a faulty component. Loose, damaged or corroded connections may contribute to a fault code on a circuit when the sensor or component is operating properly. Be sure that the components are faulty before replacing them, especially the expensive ones.

The Assembly Line Diagnostic Link (ALDL) or Data Link Connector (DLC) may be located under the dashboard, and is sometimes covered with a plastic cover labeled DIAGNOSTIC CONNECTOR.

  1. The diagnostic trouble codes can be read by grounding test terminal B . The terminal is most easily grounded by connecting it to terminal A (internal ECM ground). This is the terminal to the right of terminal B on the top row of the ALDL connector.
  2. Once the terminals have been connected, the ignition switch must be moved to the ON position with the engine not running.
  3. The Service Engine Soon or Check Engine light should be flashing. If it isn't, turn the ignition switch OFF and remove the jumper wire. Turn the ignition ON and confirm that the light is now on. If it is not, replace the bulb and try again. If the bulb still will not light, or if it does not flash with the test terminal grounded, the system should be diagnosed by an experienced driveability technician. If the light is OK, proceed as follows.
  4. The code(s) stored in memory may be read through counting the flashes of the dashboard warning lamp. The dash warning lamp should begin to flash Code 12. The code will display as one flash, a pause and two flashes. Code 12 is not a fault code. It is used as a system acknowledgment or handshake code; its presence indicates that the ECM can communicate as requested. Code 12 is used to begin every diagnostic sequence. Some vehicles also use Code 12 after all diagnostic codes have been sent.
  5. After Code 12 has been transmitted 3 times, the fault codes, if any, will each be transmitted 3 times. The codes are stored and transmitted in numeric order from lowest to highest.

The order of codes in the memory does not indicate the order of occurrence.
  1. If there are no codes stored, but a driveability or emissions problem is evident, the system should be diagnosed by an experienced driveability technician.
  2. If one or more codes are stored, record them. Refer to the applicable Diagnostic Code chart in this section.
  3. Switch the ignition OFF when finished with code retrieval or scan tool readings.

After making repairs, clear the trouble codes and operate the vehicle to see if it will reset, indicating further problems.

My 1995 elcipse gsx turbo awd transaxel will not engage when driving and switches gears alone what could be the problem it also sometines will not start right away. can any one help me


Hi there,

You (or someone technically inclined) can extract your diagnostic codes from your vehicle's transmission computer by jumping pin no's 1 & 4 on your diagnostic connector (located above your knee, under the dash). Note: this connector may be mounted upside down (but the long edge has pins 1-8).


wolfman304_6.jpg

The transmission codes are read by way of observing the flashing "N" light (i.e. the gear selector light on your instrument panel).

* Long flash = 1st digit of code
* Short flash = 2nd digit of code

Note: continuous flashing (i.e. no sequence) means NO fault codes present.

If codes are present, they will repeat over, giving you time to record the codes.

Also, if any of your other warning lights (e.g. Engine or ABS) appear to flash a code, note these also.

Write down your codes and report back here - I will advise what the codes mean.


Await your response....

Cheers,

On a 1995 honda odyssey there 's a green connector on pass side kick panel that is obd 1 now witch wires do i jump for codes ?


On 95–98 models, to access DTC memory using the MIL, the SCS 2 pin connector is located under the righthand side of the instrument panel. Place ignition switch in the On position to begin MIL flash code diagnosis.
Simply connect the two pins (a paper clip is most often used to do this) before you turn the switch on, then turn the switch to the ON position and your MIL will flash the codes.

This URL lists the codes for OBD I:
http://www.troublecodes.net/honda/hondadtc.shtml

SOME 95 vehicles had the SCS on the left hand side of the Glove compartment, under the dash. Usually the connector was blue. See pic, although I don't think this applies to your vehicle.

I have a 95 gmc 350 half ton and my check engine light comes on when I am on the highway and goes off when I drive at lower speeds. I am also getting poor gas mileage.


Most likely a bad egr valve. Take a paper clip. Jump pins A to B at the 12 pin diagnostic connector. (Top right pair wires in the connector - or - Lower left pair of wires depending on orientation) Turn key on. Count the "blinks" of the check engine light. All codes are 2-digit. Short blinks are the ones digit and long blinks are the tens digit. EACH CODE REPEATS 3 TIMES AND THE GOES TO THE NEXT CODE SET. You will get code "12" first..."b l i n k- blink-blink" It will repeat 3 times. I bet the next code will be "32" EGR system malfunction

I have a 1995 olds 88 that is pre OBD2 but it has the OBD2 connector. It will not allow me to retrive codes???


The 1995 Olds 88 has an obd 2 plug, but is an obd 1 system. Some people call it obd 1.5
There is no option to jump 2 contacts to flash the codes on the check engine light in these cars.
You will either need a compatible scan tool, or a cable to hook to a laptop and the software to pull the codes. (check out www.aldlcable.com)
One such scan tool is the Actron CP9185. It has the extra data pin for the 8192 baud communication with the computer in these cars. (pin 9 on the OBD 2 connector)

Cannot find the code connector 1995 Ram 1500


The data link connector is a dedicated diagnostic scan tool connector. It is located in the engine compartment against the fire wall. It links the engine controller to the Diagnostic Readout Box (DRBII) scan tool or the Mopar Diagnostic System (MDS), or any other Chrysler-compatible diagnostic scan tool.

What pins on the diagnostic connector do i bridge?


your owners manual usually tells you which pins to jump to get the code. you could also just take your car to checker or auto zone (or any of those places for that matter.) they usually offer free engine scans.and some even tell you what the possible problem is.

Check engine light on 2003 tacoma


The diagnostic terminal is under the dash, on the driver side. It is white, and sort of oblong, with 2 rows of femal pins. It is NOT recommended to start probing in this connector to "get a code". You may damage the ECU by probing the pins. There is no proceedure to extract DTC by using probes. You need a scan tool.
