AUT 152 - Automotive Computer and Emission Systems
This course is designed to provide the student with theory and skill in the design repair, service, and testing procedures of emission systems, and derivability problems. Electronic service precautions, computer outputs, primary sensors, monitoring capabilities, OBD (On-Board Diagnostics) systems and terms will be covered thoroughly. The use of various types of computers in diagnostic systems, such as retrieving trouble codes, diagnosing computer voltage supply, and ground wires will be presented. The student will also be prepared to test input sensors, actuator sensors, variable resistor type sensors, generate sensors, and test various computer circuits in the modern day automobile. The legislative history of emission controls, pollutants, evaporative emission control systems, PVC emission control system, exhaust emission control system, EGR (Exhaust, Gas, and Recirculation) systems, catalytic converter systems, troubleshooting and diagnosing emission systems, and engine management by computer systems will be thoroughly covered.
Upon successful completion of this course, the student should be able to:
- Explain computer operation, circuits, and design. Define OBD (On-Board Diagnostics) terms.
- Utilize testing tools to retrieve malfunction codes from the computer.
- Identify the importance of emission controls and emission control procedures.
- Interpret electronic service precautions.
- Perform basic diagnosis.
- Explain computer outputs and actuators.
- Retrieve trouble codes from various types of computers.
- Test input sensors and actuator sensors.
