Dodge, Chrysler, and Jeep OBD1 Connector Location

Unlike the GM and Ford vehicles, Dodge, Chrysler, and Jeep OBD1 models don’t include a data retrieval connector to check the error codes in the system. The system is forced into self-diagnosis through a series of ignition cycles. Without cranking up the engine, you should turn the ignition on and off twice, and on the third time leave it on the on position.

How to Read Dodge, Chrysler, and Jeep OBD1 Codes

Reading trouble codes is for a Dodge, Chrysler, and Jeep is quite a simple task. To start with, you’ll require a pen, paper, a faithfully competent partner, and some elaborate counting techniques. Next, follow through with these steps for a desirable outcome. 

  1. Firstly, you need to initiate the on board diagnosis system. 
  2. At this time, the check engine light should come up then go off before iterating through the codes. 
  3. The codes are two digit codes. Code 12 is the first to display. The check engine light will flash once, a significant pause, then flashing twice to represent the code 12. 
  4. Next, you will start receiving error codes to your vehicle. For instance, if you’re trouble code is 47, you will count 4 flashes, a significant pause, then 7 flashes.  

You could either have no error codes, have single error codes, or multiple error codes. When the onboard computer has no stored trouble codes, the computer will only flash a code 12. A single trouble code is indicated by a code 12 followed by the two-digit code representing your error. Similarly, multiple error codes have the same sequence except that there is a much longer pause between the trouble codes.

  1. Note that it would help to have a partner write down the codes for you since the codes are iterated against once. Missing a flash during the test could lead to an inaccurate diagnostic. 
  2. Finally, code 55 is iterated through to indicate the end of sequence.
  3. On completion of the above 6 steps, look up the error codes to your Dodge on the section down below. 

How to clear a Dodge, Chrysler, and Jeep OBD1 Codes

After fixing the faulty component or sensor, you might want to get rid of the distractive check engine light. This is the section in which you erase the trouble codes stored in your onboard computer system. 

Follow through these simple steps:

  1. Locate the battery under the hood to your vehicle. 
  2. Look for the negative terminal. There should be a minus sign next to it and a black cable plugged to it. 
  3. You’ll need a wrench for this step. Loosen the bolt to the negative terminal and disconnect it from the battery. 
  4.  Next, leave it in the disconnected state for about 15 minutes. The power reserve should expire in this time.  
  5. Reconnect the negative terminal and tighten the bolt reinforcing it. 

If the check engine light still illuminates after the series of 5 steps, then you might need to go through the steps once more. However, you may choose to drive for about 50 miles to reset the onboard computer. If the problem persists, then a more serious underline issue is the cause. It would be best if you paid your mechanic a visit for a more elaborate diagnosis.

Final thoughts

A flashing check engine light doesn’t have to ruin your driving experience. You can read Dodge, Chrysler, and Jeep OBD1 error codes and get a fix for the defective system. You simply need to leave the key on the on position after a quick succession of on and off series for 5 times without cranking the engine to initiate the self-diagnostic system.

Next, count the number of check engine light flashes to identify the error codes. Disconnect the negative battery terminal and reconnect it after 15 minutes for an ECU reset to eliminate the error codes after your car has been repaired.
