  1. BAR 2009 Technician Update Training Course Smog Check Failure Diagnostics

  2. Smog Check Failure Diagnostic Module Training Objectives Relevance & Importance of Smog Check Failure Diagnostics Diagnostic Skills Critical Thinking Skills

  3. Relevance & Importance of Smog Check Failure Diagnostics

  4. BAR Field Studies Quality Assurance Gold Shield Clean Car

  5. Smog Check Program Evaluation Program Evaluation The ability of a vehicle to pass a smog inspection after certification BAR Roadside Smog Check Failure Rate is 40+% 6 months after “successful” smog check repairs Based on Roadside Data

  6. BAR Technician Training Surveys Technicians “What additional training do you feel would have benefited you in your job performance? “ #1 Response Additional Training in Step-by-Step Smog Check Failure Diagnostics

  7. BAR Technician Training Surveys Clean Air Car Course Instructors 57.1% responded that the time spent on emission-related diagnostic procedures should be significantly increased

  8. Laws & Regulations Health & Safety Code (H&S) 44016 California Code of Regulations (CC&R) 3340.41(d) – The specifications and procedures required by Section 44016 of the Health and Safety Code shall be the vehicle manufacturers recommended procedures for emission problem diagnosis and repair or the emission diagnosis and repair procedures found in industry-standard reference manuals and periodicals published by nationally recognized repair information providers. Smog check stations and smog check technicians shall, at a minimum, follow the applicable specifications and procedures when diagnosing defects or performing repairs for vehicles that fail a smog check test.

  9. Fuel Costs Most Smog Check failure repairs will positively influence a vehicle’s fuel economy, performance and durability

  10. Did You Know? California’s current vehicle-dependent lifestyle has led to a dramatic increase in health risks California has more registered cars than any other state 95 percent of all Californians breathe in dangerous levels of smog on a regular basis Every year, more people die from air quality-related health issues than car accidents

  11. Did You Know? California’s current vehicle-dependent lifestyle has led to a dramatic increase in health risks 50 percent of all California’s motor vehicle pollution is produced by only 10 - 15 percent of the state’s total number of cars driven A poorly maintained or malfunctioning vehicle can release as much as 10 times the emissions of a well maintained vehicle

  12. Summary BAR Field Studies + Smog Check Program Evaluations + Training Survey Responses + Laws & Regulations + Fuel Costs + Public Health = Opportunities to Improve Smog Check Repair Effectiveness
