This Recommended Practice provides transit bus maintenance training and departments with typical information to evaluate, develop or enhance current training programs for the diagnosis, repair and maintenance of transit bus doors and interlocks. Individual operating agencies should modify these guidelines
to specifically teach the coach and OEM manufacturers and modes of operation on their local equipment. The training assumes prerequisite knowledge in basic electrical, air operational controls, basic mechanical aptitude, and schematics reading electrical/electronics, including PLC where applicable. The depth of module development should be consistent with the operating agency’s level of repair requirements as defined by the agency’s Vehicle Engineering and Maintenance Department.
