my display came on and says service required contact dealer now. i changed the ccv filter and tried reseting it the way the dealer told me. i have the H&S mini max dpf delete down pipe delete and the egr delete. please help its anoying to drive with that thing going off all the time.

 

Do you have your owner's manual? If you do than read the pages on the OHD messages and resetting the OHD follow the instructions provided. It may take more than two times to get the display to clear also.

ok i read the owners manual about the the overhead which i found out is called the EVIC . But it doesnt say how to clear it. can someone help me with how to clear it,

 

Hi...my display says see dealer now quite often.....I have a smarty jr..I clear codes with the smarty even if there are none...and that will fix that..if I put it back to stock it will show about three codes..I clear it then program again...all good. It seems like my overhead display shows it every 2,000mi. or so....

 

back again....also there is a thread on this procedure...good luck!

 

First what year truck and how thick is the O&M guide?
I have two manuals for my 2008; one is a diesel supplement for the 2008 O&M guide. The other manual provide detailed information on how to reset the display for various issues like oil changes and the crank case ventilation filter.

My truck is a 2008 . I found in the owners manual where it talks about the evic. but doesnt tell you how to clear it. It says "service required see dealer now" but i have everthing deleted on my truck except the egr cooler.

 

Per the supplemental booklet for the 08 trucks; this message is posted when the Regeneration has been disabled. See page 81 in the diesel supplemental book. The ECM thinks there is an issue with the DPF and the truck has not regened and has malfunctioned.
I think to eliminate this issues you will need to go over the instructions that the H&S min-max provided to do the deletes and you may need to reload the software from the H & S program to eliminate this issue.
You may want to contact H & S for additional help.

The H&S has 2 different download options, DPF present and DPF removed. Reload the program to your truck being sure to select the DPF removed setting. This will prevent the ECM from looking for sensor input from the DPF and associated regen cycles.
