Medium Heavy Truck Diagnostic Technician

The Medium Heavy Truck Diagnostic Technician Certificate offers both theoretical and hands-on training, including electrical systems, hybrid & electric vehicle systems, hydraulic and autonomous vehicle controls. Course work prepares students to take the Automotive Service Excellence (ASE) exams. Students enrolling in the program should have the desire and ability to work with their hands, demonstrate critical thinking, possess a high degree of mechanical aptitude, and enjoy working in a shop environment. Program completers should be able to find employment as advanced entry-level apprentice Medium Heavy Truck technicians.

The former 7-unit certificate had an average of 10-15 completers per year; we anticipate the new certificate will have 10 completers.
