My 2001 Ram would allow me to turn the key of and on quickly a couple of times and it would go into self-test and display all stored codes in the odometer.

My 2007 CTD won't seem to do that. Is that feature still available and just hidden or did they do away with it so they could charge for the codes?

Had all six injectors replaced and almost made it around the block before the MIL came on. Would like to know the code(s) before going back to the dealership. Interesting, two were bad but all six were badly carboned according to the tech report. 41000 miles and 2 1/2 years...

Any ideas?
