sorry i cant help with ur problem but how exactly do u do the key trick? i read something about turning the key on and off like 3 times or something like that and i couldnt get it to work. sorry its kinda OT

 

If you have a dig truck. Hold down that little thing that sticks out turn the key to the on position and it will do a test/scan.

 

heres a vid i took, do exactly as in the vid, and youll see a code.
basically you cycle the key off and on 3 times, and the 3rd time youll see Pxxx on the digital odo.

so u didnt even do anything with the button that resets the trip like max said? cause i did exactly wat u did and i didnt get anything unless u have to be showing ur trip odometer

 

you have to do just that fast, also make sure its off for atleast a few mins befroe trying again, as it wouldnt work for me after doing it the first time.

nope, i did exactly what you see in the video i took/posted. nothing more, nothing less.

 

Well that is what I do with mine. I'll have to try the key thing and see what happens.

 

Its pretty simple, really. Turn the key from the off position to the on position (just before starting) 3 times, and on the 3rd time leave it in the on position. The code(s) will pop up where the digital odometer is. If the check engine light is not on, no codes will show (P-done).

 

i tried the turning the key on and off 3 times and it didnt work. i did wat max said and just held the reset button for the trip down then turned the key on. it said check then did this little speel and then just went to my odometer and didnt display any codes. but i know i have a code my CEL is on. i think it is a P0720 for my output speed sensor but it didnt show up
