HET 3020 - Electronic Diesel Engine Control

Electronic Diesel Engine Control is designed to provide students with the foundational knowledge and skills to perform maintenance on diesel electronic control systems. Safety and proper tool use are emphasized throughout this course. Specific topics include diagnostic and maintenance procedures. As part of this course, students apply knowledge and skills by participating in diagnostic and repair activities associated with diesel electronic components. This course must follow the guidelines and standards set forth by Automotive Service Excellence (ASE) and National Automotive Technicians Education Foundation (NATEF) minimum standards. Workplace Employability Skills Task lists should be incorporated into the Diesel Program.
