Also already replaced ecm, vecu and lcm.. i was able to idle the truck but still dont have communication at diagnostic plug with ptt vcads, and still no pedal responce.. if only i could get signal at the diag. Port i can start proorammin vecu and lcm but im thinking that i might need to replace abs and srs computers too.. since i keep getting a "Check Data Link Broken" message.Last edited: May 22, 2016

Unplug those ABS and SRS computers. How did you check J1939? Remove one resistor and check with ohmmeter resistance of the line and resistor on other end of the link, right? Check both lines to the ground and +12 v with batteries disconnected.
This bad idea to high jack someone also old thread
Hopefully admins can move it05VNLDC Thanks this. -
Thats correct! How i checked the data link.I will try the check to ground with all computers disconnected. Thanks for your help! -
Would I need to program the vecu after replacing it.

My truck doesn't turn on engine brake or cruise control. Today it stopped showing mph. So I'm thinking replacing the vecu would fix my problem. What do you guys think?
