I don't know if pre '03s do this, or not, but if you have a check engine light on, you can turn the key on and off three times and the error code will display right on the digital odometer. Pretty cool...

I had a check engine light come on in my truck. The code was for insufficent slip in the torque converter. I called Clint @ ATS about it, and he said this is a normal error/code with the CA Dodge trucks running the triple lok TC. He said the only work around is to set the trans commander to allow a higher slip.

Yup it is pretty cool! I have had to use it to find a code already when I had a ETC- ie drive by wire light come on. It was just like you said three clicks of the key , and up came my code. I was able to then go fishing the net for TSB's , and right away I was able to find a TSB concerning a reflash. (this is for a Hemi 2500)

There is another self check , and it involves holding the trip/odo button down turning the key to "on" for a couple of seconds. This will run the guages through a complete self diagnostic. You have to try this because it is a trip. I only found this because that is what someone told me was how you recover the total hours the truck is on.

I can do something similiar on my '86CJ7 with the MPI kit.
I turn the key on-off rapidly 3 times and the check engine light
blinks the fault codes. Sure is a help in troubleshooting.

Fuel injected Chrysler products are all like this. I wasn't aware that they still could do it after OBD-II though.

It worked on my 2001 CTD . Here is a link to help with the codes.

Works on my 94 OBD I Ram. Funny I was just talking about this a little while ago

That worked on a buddy's '01 1500, but it never would work on my '99 1500.

My TJ does this. Of course, I get the code that's not on the list. :shaking:
