Diesel Technician

The Associate of Applied Science, Transportation Technologies, Diesel Technician Program trains individuals for apprentice-level positions servicing, repairing, and maintaining heavy equipment and over the road long-haul vehicles. The program emphasizes principles of operation, diagnosis and service procedures. Using the latest technology in diagnosis and repair equipment, this comprehensive training prepares graduates with skills that are in high demand in the diesel repair industry.


Students completing the emphasis will:

  • Identify and implement safety procedures involved in diagnosis, service, and repair of all major medium/heavy duty truck and heavy equipment components and systems.
  • Analyze and interpret diagnostic and test information to formulate correct repair procedures.
  • Demonstrate correct repair strategies and techniques by applying knowledge of system operation and demonstrating mechanical skills to accomplish repair tasks.
