Cow farmer Posted November 16, 2021 Share Posted November 16, 2021 I have a 2004 cx613 with AC460p engine. Went to start and cranks with no fire. Had a 6-4 code for me. I checked all data lines and everything tested as it was suppose to. Found replacement eecu and vecu from running truck. Swapped and still no fire. Took to dealer. They worked on it and now it has a 6-3 rather than 6-4 code. They could not figure out any issues. Took to independent shop that works on these regularly and they are struggling as well. Is there anything we should be looking at? Thanks Quote Link to comment Share on other sites More sharing options...
Vmac3 Posted November 17, 2021 Share Posted November 17, 2021 You have a fault for the J1587/1708 data lines. Disconnect power from all non Mack Modules (ABS, Satellite) first. See what happens. V 1 Quote Link to comment Share on other sites More sharing options...
