Summary

This Recommended Practice provides transit bus maintenance training and transit bus maintenance departments with typical information to evaluate, develop or enhance current training programs for the diagnosis, repair and maintenance of transit bus fan drives. 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 electrical and electronics concepts, including the basics of bus multiplex operations. 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.
