The DPFs didn't go into use until 2008... if you have one with a DPF, you can't do a forced regen on your own - you can only do a parked regen when the system calls for it. Once you see the dash light, you hold the regen button for four seconds, and it should kick on automatically (so long as you don't have any active fault codes). To do a forced regen, you'd need the Cummins Insite software.
