A buddy of mine has a ’06 3500 CTD Megacab. The truck threw a CEL the other day. The CEL cleared after 4 or 5 restarts. I was going to help him retrieve the code and get a little insight before it went to the dealer. I had him do the three key deal and the truck would not display any codes or the done message. After sitting for a few seconds the CEL flashed 10 times and stayed on solid. When the truck was started the CEL went out. Is there a new trick for code viewing on the 2006 models? Any insight would be helpful. The truck is heading to the dealer today for a few minor things and a look into this.

Thanks in advance,

Mine works (thankfully it only shows "P-Done")

Are you sure you are not going backwards into Accessory? Just go from OFF to on 3 times, staying on "on".

 

I couldn't get mine to work either. I found that on my 06 you have to cycle the key three times FAST to get it to work.

 

My Father-in-law's 06 doesn't work either????

 

When my truck was at the shop i asked the techs, and was told you could no longer pull codes by the key cycle drill.

 

They are mistaken.

 

Key cycle code reading works fine on my 06.

 

Just as Scottrod said; the key has to be cycled "fast". cdru

 

Thanks all. I will tell the guy he is just to stinkin' slow.
