Guide to Modern OEM Diagnostics Systems

OBD, ECU, diagnostics, emissions - Explained by Greg Banish

Welcome to the world of onboard diagnostics (OBD) systems, where vehicle diagnostics and emissions control are made easy! OBD has been an integral part of vehicle design for decades, and since 1996, OBD-II has been mandatory for all cars manufactured in the United States. These systems have evolved to meet emissions requirements placed on the automotive industry, resulting in increased complexity in electronic controls and error reporting.

Luckily, there has been some commonization in the industry, making it slightly easier for repair technicians and do-it-yourself enthusiasts to work on these challenging systems. In fact, many states now require vehicles to pass an OBD check during registration renewal, emphasizing the importance of proper operation to consumers.

If you want to dive deeper into the world of modern original equipment manufacturer (OEM) diagnostics systems, you've come to the right place! Greg Banish, a former diagnostics and performance calibration engineer, serves as your expert guide in this insider's guidebook. He takes you through the critical functions of the electronic control unit (ECU), shedding light on why the dreaded "check engine" light on your dashboard is illuminated. When problems arise, Greg provides strategies for troubleshooting and finding solutions.

While it's impossible to list every imaginable repair, this book establishes a solid foundation by explaining ECU logic in plain English. In addition to repair tips, you'll find valuable advice for those interested in modifying their vehicles while still maintaining the full functionality of the emissions and diagnostics systems.

Harness the power of the ECU diagnostics to improve your ability to find and execute the right repair on your vehicle. Whether you're a DIY enthusiast or simply want to understand how these systems work when dealing with service professionals, this guide is an essential resource.
