I had this happen back in 08 and if I remember I replaced the APPS with one from Timbo. Does this ring a bell with anyone. I have an 04 2500 HO CTD. I need to fix this code so I can sell this truck. Thanks for the help, Fred

Just called the dealer and the APPS price is $629.00
 
If you want to do UDC and eventually on-the-fly tune changes then you will need to upgrade to a Smarty Touch and the ComMod when it comes out.

The S-06 with UDC is worth it to start custom tuning.
