This manual can only be purchased with the Catalytic Converter Diagnostics webinar. This manual will not be sold once the webinar starts on August 25, 2021.
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.
