- Interface with vehicle’s on-board computer; perform diagnostic procedures using recommended electronic diagnostic equipment and tools; determine course of action.
- Locate and use relevant service information for diagnostic procedures, flow charts and wiring diagrams.
- Inspect and test sensors, controls, actuator components and circuits; service as needed.
- Retrieve DTCs using scan tools and identify the relationships between DTCs and failures that cause them.
- Navigate between multiple electronic service publications, Wiring Diagrams and Workshop Manuals while following diagnostic subroutines.
- Disassemble and reassemble select fuel system components using the correct tools and service procedure.
- Visually inspect components such as cylinders, fuel injectors and turbochargers for failures.
- Identify components, describe their function, identify and perform diagnostics, service and maintenance for this Diesel sub-system.
Assessment and Requirements
Homework, quizzes and a written final examination. Measurable objectives will be evaluated by the instructor based on the accuracy and proficiency of objective completion.
Students must take notes on demonstrations, carefully read and analyze assigned course materials and perform exercises to determine their competence in diagnosing servicing modern electronically controlled diesel engine systems.
