cummins n14 celect plus checking fault codes

anyone know if theres anyway to check fault codes on an n14 through the dash without having to go through cummins insite to check for codes, I know the isx15 can but Ive been used to working on mechanical n14's, started working for a new company and some of the older trucks have the celect plus with electronic injection and it comes up on the dash with the number of fault codes but waiting on laptops to come in from cummins, not for about 2 weeks and I have about 12 trucks and 24 trailers I need to fully inspect, service and repair by next Friday and I gotta get rid of those fault codes before dot comes to do annual inspection on the trucks
