School Bus Diagnostic Tools

TPX Power Source is your leading source for School Bus Diagnostic Tools. We have 44 years of School Bus Fleet experience and this strong relationship has led to the development of the School Bus Tool SB-II. This tool is being developed by School Bus Fleets and the Service Managers who have dedicated their lives to the safe transportation of children. Our goal is to provide an affordable diagnostic tool for the School Bus vocation. Together we will develop a great Diagnostic Tool that will communicate with International IC, Thomas, Freightliner, Bluebird, CAT, Cummins, Detroit Diesel/Mercedes, Meritor Wabco, Bendix, ZF TRans, and Allison Transmissions. Don't forget the White Fleet! We will help with those vehicles.
