unfortunately being a 95 that was the cross over year to obd2 todays scanners may plug or not and may read computer info or not another way to check codes on the older chryslers is to turn the ignition on and off three times third time leaving ignition forward watch the check engine light and it should start flashing count the flashes example three flashes and a pause then four more flashes would be code 34 each code should repeat it's self twice then moving to next code when codes are finished engine light will go out if any codes were missed you will have to repeat the three times on and off also recommend doing it a few times to make sure you have gotten the codes correct

Clearing the codes is simple that is done by removing the fuse of the EFI from junction box 2 for 10 seconds. Make sure to remove the jumper wire and switch the key off before clearing the codes.

Code 12 and Code 13 Rpm signal circuit fault
Code 14 Igniter signal circuit fault
Code 16 ECT control signal fault
Code 21 and Code 28 Main oxygen sensor fault (for ES300; SC300 & GS300 models)

Code 24 Intake temperature sensor circuit fault
Code 25 and Code 26 Air fuel ratio fault (for ES300 & SC300 models)

Major transmission problem. That's what the flashing Check Engine light means.

If the Check Engine light is on all the time, it means there is a "fault code" stored in the computer. Take it to an auto parts store (like Auto Zone) and ask them to read the codes to see what it says. They should do it for free. If they won't, go to another auto parts store.

1987-97 VEHICLES EXCEPT 1997 MODELS WITH 16-PIN DLC

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.

Fig. Fig. 1: ALDL/DLC terminal identification for 1987-97 vehicles, except 1997 models with a 16-pin DLC
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.

Trying to find out which pins to cross for engine codes and the location on 1995 isuzu pickup


Hello ipontrees40: My name is Roger and I will help with your answer. Locate the ECM on the left kick panel. There will be a lead of wires that has 3 leads hanging. Connect the white and black wires together. Turn the key on and observe the check engine light. Should flash i sequeince of 12, will flash once pause followed by two quick flashes. This is code 12. Any codes after the 12 will be stored codes. Be sure not to start the engine when checking the codes. Should you start the engine you may not receive the correct information. The codes will be read as slow flash followed by a long pause followed by quick flashes. For examle a code 42 would be 4 slow flashes followed by 2 quick flashes. After the computer has read all storer codes it will go back to code 12. After you repair the problem you can clear the codes by either removing the negative battery cable or #3 fuse for ten seconds. Remember just because there is a code does not mean that part is bad. You need to follow basic trouble shooting to make a propper repair. Just replacing parts becomes expensive. I attatched a picture of the jumper wires to the computer to help in identifying them .
Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Rogerrogerf1_52.jpg

Where do I find the wires that I apprently need to cross to get the check engine light to flash in order to get the codes?


Remove the kick panel just beside the left foot rest on the driver's side.
2) Locate blue wires.
3) Locate black connector. Hold it notch up.
4) With ignition off, insert one of the wires into top row, 2nd pin from left.
5) Turn key to on position, but do not start the car.
6) Watch blinky check engine light on dashboard. Count blinks. Long blinks = 10, Short blinks = 1.
7) Keep watching blinky light until you get mesmorized.


To clear codes (after problem has been resolved):
1) With engine off, stick the blue wires to 1st and 2nd pin in the top row counting from left on the

black connector, with notch facing up.
2) Start car. Shut off car. Remove pins.
3) Read codes to make sure they are clear. No codes = steady blinks at 1/4 second intervals. yhis is for the 94, 92 should be the same. have a good day !!

What is the diagnostic code?


96 and newer is the OBD-2 scanner to use, for 95 and older gm vehicles go to this site for the codes--- www.gmtuners.com/0BD1_DTC.htm----- heres how to read codes on 95 and older, The ALDL connector is on the driver side of the car by the steering column. Short the A and B pins together, which is the two pins in the upper right hand section of the plug. Make sure the key is on, but the engine is off. That will make the check engine light flash whatever codes are stored in the computer. You can use a paper clip to short the pins together. Hope this helps. to read codes, 3 flashes of check engine light, then pause then 2 more flashes indicates problem code 32. thats how you read the codes. so have something to write them down so you can keep track of the codes.

How to check abs codes on 97 lexus es300


Locate the DLC1 connector under the hood. Open the cover, if equipped, and remove the short pin, if equipped.
After removing the short pin of the DLC1, connect terminals Tc and E1 of the DLC1 to make the ABS Warning Light blink and output the DTC after you turn the ignition on.

A flash, long pause, two flashes, long pause would indicate a "code 12" and so on.
