I just bought my wife a 99 ctd about 3 weeks ago, and was just wandering what year they started puting the code read-out in the dash. I cycled the key three times and did not see anything. So maybe it doesnt have this option.The truck does not have any problems yet, and we are puting all of the guages in this weekend.

 

No key trick for the 99's...

 

Thank's for the info. I was hoping that it did have the read-out.
