Advanced Emissions & Drivability Diagnostics


ATG has partnered with the California Institute of Automotive Technology (CIAT) to provide turn-key curriculum for the 2013-2014 16-hour Smog Technician update requirement. This package is available to all public and private schools and trainers certified to provide Smog Technician training, and includes:

  • A 170-page manual
  • All tests and answer keys
  • A PPT file covering 16 hours of lecture and lab, with detailed slide notes
  • Forms for Lab Exercises

Manuals can be purchased though CIAT by email at , or call (760) 471-9848. When multiple manuals are purchased for a class, the PPT file and Lab sheets are included at no extra charge.


Course Description:


Section 1 lays out a field-tested disciplined diagnostic approach that works for code, no code, drivability, electrical, intermittent, and other fault categories. Case studies are used to show how complex problems are conquered, and how easy problems are diagnosed much quicker than using traditional methods.


Section 2 covers 5-gas emissions diagnostics from a perspective not seen in other curriculum – from the ‘trenches’. This section outlines real-world diagnostic techniques with case studies, and covers new testing procedures devolved and proven in shops. The material and case studies are weighted towards finding root causes for common emission failures that are often blamed on the wrong systems and/or components, so attendees will see better and faster emissions repairs.


Section 3 explains Advanced Drivability strategies we call ‘Top-Down Diagnostics’. The premise is to stop testing everything in detail and start testing categories of faults. This method allows you to drill into a root cause without wasting time on tests that could easily have been ruled out. Broad categories are used at first, including Volumetric Efficiency, Fuel Trim, and Cylinder Contribution, but in ways not commonly taught in the industry. There are plenty of compelling case studies to make sure the message is clear. ATG has developed and implemented these strategies in seminars throughout the country, so we’ve seen the results:  Technicians make more money while simultaneously benefitting both the environment and the customer through better running vehicles.
