BAR Specified Diagnostic and Repair Training is intended to provide students a high level of competency in the diagnosis and repair of Smog Check failures. This training focuses on the areas of electrical/electronic systems and engine and emission control performance. Students with at least two years of engine performance repair experience and who successfully complete this training may qualify for the state licensing examination for the Smog Check Repair Technician License.
Course Objectives: By completion student should have strong knowledge of
1. Describe and demonstrate personal, shop, equipment, and vehicle safety practices.
2. Explain the causes and effects of air pollution as it relates to the automotive industry.
3. Explain the standards of practice pertaining to Smog Check licensure.
4. Locate, assess and apply vehicle service / repair information, in the process of Smog Check diagnosis and repair.
5. Employ appropriate diagnostic and repair processes based on the customer’s complaint, the cause of inspection failure, or vehicle data / information.
6. Establish a level of priority with respect to the repair of a Smog Check failure using inspection and vehicle data / information.
7. Describe principles of electricity and electronics.
8. Define electrical terms of watts, voltage, current and resistance.
9. Describe and identify the types of automotive electrical circuits (series, parallel, and series/parallel).
10. Describe and identify the types of electrical and electronic components used in computer controlled automotive systems.
11. Describe theory, design and operation of automotive electrical and electronic systems.
