Having an OBDII scan tool is useful in many situations when an engine light comes on.
But what if you don’t have an OBDII scan tool and need to know the code?
Many vehicles have a built-in diagnostic that will give the code, as I recently found out with Dodge cars and trucks.
I have not 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.
How To Read Dodge Check Engine Light Without a Code Reader
- Cycle the Key from OFF to ON three times.
- The last cycle, the key should be in the ON position.
- It will give the code in the odometer LCD window on the dashboard.
- The code will show for only a moment and flash P-done before going back to normal.
- If you miss the code since it does flash quickly simply repeat the steps.
Summary
If you do not have an OBDII scan tool and want to know the error code number, the above method works on many Dodges.
Once you have the code, use Google to look up the code number along with the year of the Dodge, and the problem with your car or truck can be found.
The code will point to a specific problem the vehicle is having and show what needs to be fixed.
Reading through forums on the vehicle year and the code can be very beneficial and help fix the issue.
Another free method to get an OBDII scan is to take it to an auto parts store since many will do a scan for free.
Hopefully, this helps if you have a Dodge and don’t have an OBDII scan tool to see what the code is.
If this works with your Dodge, let us know in the comments below.
This worked for 2013 Grand Caravan when I put the trip meter on the display. Didn’t work when odometer reading was on the display.
Worked on my 09 Dodge Avenger but only said done so hope it’s not something horrible
Worked like a champ on our 2017 Grand Caravan.
Yes
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
Yes, this did work for me on my 2006 Dodge Grand Caravan.
Doesn’t work on all dodges. Doesn’t work on my 06 2500 5.9.
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.
Yes this worked on my 04 dodge Durango
I have a 2015 grancaravan crew. It has the big black fob that goes in ignition. There is no key.
How do you do the 3 turns on off to work.
Thanks Gary
Works perfectly on a 2005 Grand caravan SXT with a 3.8 V6
What was the problem
Didn’t work on 08 Ram 2500 diesel.
Didn’t work on my 2005 Dodge Dakota – no Code – but the engine light symbol started flashing
The flashing is the numerical code so every pause is a different number
Doesn’t work on a 2004 dodge ram 1500
I’ve got a 2005 Dodge Ram 1500 and it worked for me
Doesn’t work on our 2004 Dodge ram 1500 hemi
Didn’t work on my 1999 dodge ram.
Just being sarcastic. Nothing works on 99s I owned one of those ××&%@/>%×$>÷+>[%! Things lol
If the code doesnt show digitally check engine light flashes pauses flashes 4 times cthe number of flashes lije 2 1 4 3 thats the odb code you need to look up
Worked on my 2003 Dodge Caravan. Thanks!
It worked once and I wasn’t prepared for several codes and now I can’t get it to work again?!?! It just does ———— and –done–
Works on my 2013 dodge grand caravan
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.
Worked on my 2011 Dodge Grand Caravan. Thank you, sincerely!
Likewise with my 93 caravan.
Didn’t work on my 2015 Dodge Dart
Worked on my 05 Dodge Ram 1500 5.7 Hemi
I have a 08 dodge ram that wont start shows dash lights but wont turn over . I hope this works on mine.
What do you do if it’s a push button start?
Worked without a problem in a 03 Dodge Ram 2500 van
Works on 2008 Grand Caravan 3.8. Thank you!
Didn’t work on my 98 Dodge Durango.
2008 Dodge 5500 67 diesel I had to put it on the trip turn the key on and off three times the trip went to straight lines said flash the code then the word done check engine light blinks 10 times stopped started the truck check engine light went off cleared the codes I did figure out if you don’t get it to show the code on your first attempt you must start the vehicle shut it off in order for the trip meter to show the code
Work on 2010 3.8 (HERO). Put it Trip A. cycle if fast.
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).
Hello , are you able please to explain more , because I have the same vehicle but it didn’t work
Thank you for these great instructions. I found that putting it at the odometer setting didn’t work but putting it on Trip A setting did with the key turn 3 times from 1 – 2. Mine is just the EVAP leak so have re-closed my gas cap and will see if that fixes it. Dodge Grand Caravan 2012.
This post describes the process best. Worked on my 2011 Grand Caravan.
Didn’t work on my 2011 Dodge Nitro…😔
