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 emissions control systems. Individual operating agencies should modify these guidelines to specifically teach the coach and engine manufacturers and modes of operation on their local equipment. Instructors should be familiar with local and state emission requirements for transit busses. Note that California has multiple emissions regulations in various jurisdictions within the state, plus statewide requirements.
