Course Description: This course develops the skills needed to safely diagnose, repair and maintain the systems and sub-systems specific to heavy duty and over-the-road diesel powered vehicles. Topics will include: Diagnosing problems in mechanical, electrical, pneumatic, and electronic systems with industry standard test equipment; Troubleshooting the sophisticated electronic controls that govern engine performance and horsepower as well as transmission and braking systems; Troubleshooting steering, hydraulic, pneumatic systems, brakes, axles, differentials, electric motors, and compressors. Students will learn heavy-duty industry standardized safety inspection procedures.

Upon successful completion of this course, the student should be able to:

1. Troubleshoot and perform repairs on heavy-duty mechanical, electrical, pneumatic, hydraulic and electronic systems.
2. Use computers and industry scan tools to diagnose heavy-duty equipment and research information.
3. Perform preventative maintenance such as safety inspection, engine tune-ups, front-end alignments, and air brake adjustments on heavy-duty equipment.
4. Operate common heavy-duty shop machinery and equipment.
5. Select and use precision tools such as torque wrenches, micrometers, dial indicators, tap and dies, bore gauges, and other industry specialty tools.
6. Analyze unique faults and situations, create a diagnostic plan, and make informed professional decisions.
