Item is A Guide to Understanding IM240 Manual. Published in 1994, this book discusses the implementation of the Federal Environmental Protection Agency’s (EPA) new vehicle inspection maintenance program. Called IM240, its short for “Inspection/Maintenance 240 Seconds”.
IM240 establishes the most stringent emission standards that have ever been required (up to that time). It involves some of the most sophisticated and complex testing methods ever developed. Surrounded by controversy, and driven by legislation that is set forth in the Clean Air Act of 1990, IM240 is a reality.
This 100 page book has been written to answer many of the questions that you may have about IM240. This book is NOT intended to teach you how emission devices operate, how they should be repaired how to read a schematic, use a DMM, or interpret the pattern on a dual trace oscilloscope.
This book WILL teach you what IM240 is, how I/M tests are run, and what may cause a failure. It will target the knowledge that you must have to diagnose and repair I?M failures. Areas such as equipment, certification and upgrade training are also covered.
The overall condition of the manual is good.
