How To Read Dodge Check Engine Light Without a Code Reader
Having an OBD2 scan tool is useful in many situations when an engine light comes on.

But what if you dont have a scan tool and need to know the code?

Many vehicles has a built-in diagnostic that will give the code as I recently found out with Dodge cars and trucks.

I haven’t tried this on all Dodge cars and trucks but it certainly worked for me on a 2001 Dakota, and many others have stated this method has worked for them.

The steps are easy with the key simply needing to be cycled on and off three times.

  1. Cycle the Key from OFF to ON three times.

  3. The last cycle the key should be in the ON position.
  4.  

  5. It will give the code in the odometer LCD window on the dashboard.

  7. The code will show for only a moment and flash P-done before going back to normal.

    Simply Google the code number along with the Dodge make/model and the problem with your car or truck can be found.

    If you miss the code since it does flash quickly simply repeat the steps.

    Hopefully this helps if you have a Dodge and don’t have a OBD2 scan tool to see what the code is.

    If this works with your Dodge let us know in the comments below.

    Does not work on 2014 Ram 1500. It turns on the engine symbol but does not give the codes.

    Doesn’t do anything. Tried over a dozen times. I can pull C codes by holding the trip button in and turning on the key & releasing the button, but the 3 times off – on does nothing.

    I have a 1996 Dodge Grand caravan it did not have that little reader you reporting to but if you do the off and on three times on the four time the check engine light will flash the code that will help

    Worked perfect on my 2014 Dodge Grand Caravan. Just needed to ensure the display was on odometer and turn the vehicle completely off. Next, flip three times between position 1 and 2 with the key (maintaing that the positions are 0 – at key insert, 1 – at first click, 2 – at second click, and 3 – at starter). Ended o 2 like the instructions. The error codes just popped up right after that (I had 2 codes appear).

        Works on my 2006 Ram 2500 5.9 Cummins just fine. QUICKLY off to run 3 times and you’re good to go. I’ve never had a Dodge this didn’t work on when done correctly.
