checking for codes

From : dirtclod

Q: i had a 2000 ram 2500 ctd and to check the pcm for codes i could cycle the key 3 times and any codes would appear in the odometer. this doesnt work on my 2004 durango hemi or my 2007 2500 4x4 ctd. is there another trick to retrieve any codes for the vehicles .
