This course will update the Technician's knowledge and understanding of modern-day diesel vehicles. It covers the theory, operation, and diagnostic processes of diesel engines. Additionally, the course provides an in-depth knowledge of new technologies that lower emissions through a new generation of aftertreatment emission control systems.The course discusses fundamental diesel topics such as diesel engine operation, compression fuel ignition, air intake systems, and turbocharging. It also covers diesel aftertreatment OBD II monitors.

The course commences with a chapter on fundamental computer operations, offering a refresher on how computers function and make decisions. Subsequently, it delves into the purpose and functionality of the OBD II system before progressing to various diagnostic approaches, such as the 8-step method, Symptom-based diagnostics, Mode 6, and Fuel trim diagnosis. 

Hybrids have become mainstream in the USA, and as the EPA mandates stricter gas mileage and emissions requirements, manufacturers are set to meet these demands. This course introduces students to a basic understanding of all the systems on hybrid vehicles and the fundamentals of the different types of hybrid designs such as Series, Parallel, and Series-Parallel. The course will strengthen students’ knowledge of generators, inverters, and converters and will provide a thorough understanding of the difference between high-voltage and low-voltage systems. Additionally, the course will cover regenerative braking systems and safety techniques that must be followed by all technicians working on or around hybrid electric vehicles.

The world of automotive diagnosis has evolved significantly with the introduction of complex systems like CAN Networks, Variable Cam Timing, Throttle Control Systems, Direct Injection, and Air Fuel Ratio Sensors. This course is designed to equip students with the knowledge and diagnostic skills required to effectively diagnose and repair vehicles utilizing such intricate systems. Each chapter will delve into the theory and operation of these systems, offering practical diagnostic strategies based on real-world scenarios. By the end of the course, students should have a solid understanding of five critical systems that are often challenging to repair.
