This manual can only be purchased with the Catalytic Converter Diagnostics webinar. This manual will be removed from our website once the webinar starts on June 22, 2022.
This manual is an optional 134-page manual developed by ATG in cooperation with Walker Emissions Control. The manual covers all of the tools, tests, and case studies in the presentation, so it’s a great resource for reproducing the tests back in the shop. The manual also keeps you on a disciplined path so you will verify that each vehicle is operating well enough for converter operation before testing actual converter efficiency.
