Frist off, I have a 2008 Pete with a factory 600 C-15. While traveling at any speed with or without cruise control, I hear an audible pulsing of the engine. If I just tickle the accelerator, it disappears. It does not seem to affect rpm levels nor does it feel odd.... It is just a rythmic sound and keeps a steady rythmic beat. What is this?
Secondly, the switch on the dash for the DPF. How do i use it? It appears to be a three position switch.
Third, the jake brakes activate only after applying the service brakes. I'm assuming this be a setting within the ECM correct?
Any advice much appreciated. Thanks much!

Regarding the first, that's part of the newly integrated Concert Class audio system.
...jk. I know nothing of the new Cats.
Concerning the second, look to your manuals for guidance. If you don't have them, go to Pete's website and look under their 'resources' to download a copy of the guide supplement to the owner's manual. Do some digging, I know it's there. I would say they have covered most of the bases, but I find that the best thing to do is leave the switch in the middle position and let the ECM control the dpf process automatically.
Lastly, yes the engine brake's service brake activation is an ECM parameter that can be easily changed to suite your personal preference. -

SHWEEEEEET, I just need to keep pace with the concert class beat eh? LOL.
Searched hi and low for manuals, no can find via www. I['ll search again.
I'm truly concerned with the rythmic idle.... bugs the heck out of me! Anyone else, please chime in.
Thanks for the reply. -
