CM 871 Fault code 285

[2dlb]

Hi Guys. I need some help on another problem. I have a 2009 Pete 386 CM871 2733 cpl we purchased knowing that it was likely demandated and it was. Because of where we are to properly operate we need to make this emission compliant. So new doc, dpf, found the block plates, did rawzes tune up, turbo was leaking oil had it overhauled (thank god we hadn't put on a new one), found cracks in the ATA,replaced. front cover leaking so we resealed that and while we had it off we put on a new harmonic balancer. Had the ecm recaled and after noticed the check engine light on. Insite shows a fault code 285 a J1939 multiplexing PGN Time out error. In insite it comes back to Cruise control,Service brake switch,Cruise Control Set switch , Resume switch, Idle increment and deincrement switch. I have checked wiring and fuses, cycled each switch while watching in parameters and they are functioning. I read in the forums where the paccar ecu was finiky and disconnected the battery's for 1hr and have not found the problem. Any thoughts Thanks
