More than 4,000 OBDII fault codes are compiled and qualitatively described in this compendium of generic and manufacturer-specific proprietary fault codes for common vehicles. The diagnostic connectors, protocols and their classifications, breakdown of fault codes, and vocabulary used to describe components are detailed in the discussion of the anatomy of the OBDII scan tool. This comprehensive reference to fault codes aids in diagnostic assessment by making clear the nature of an automotive problem so that beginner and advanced technicians can make effective repairs.

The principles of tuning OBDII vehicles are outlined for do-it-yourself novices and repair professional alike in this introduction to automotive electronic diagnostics. Beginning with basic automotive concepts of engine operation and the powertrain control module, topics span the history of OBDII, anatomy of the scan tool and its components, and the language and protocols that the OBDII uses to communicate faults. Diagnostic tips and detailed fault code descriptions for major domestic automobile manufacturers including General Motors, Ford, and Daimler-Chrysler accompany tips for Asian and European vehicles. The straightforward prose and cooking recipes listed at the end contribute to this comprehensive primer to electronic diagnostics.

The definitive DIY manual on automotive diagnostic fault codes. Covers code retrieval with and without a fault code reader. Includes fault code tables (including EOBD systems), sensor and actuator tests, maker-specific chapters and code clearing procedures. Unique colour section shows location of EOBD diagnostic plugs.

In the early part of the 21st century, we find our lives intertwined with a maze of technological wonders. From cell-phones to personal computers, no human being today can escape it. Automobiles are no exception to this rule. With the ever changing emission laws of today, the one constant in the automotive industry is that things always change and will continue to do so. OBD II was designed from the beginning to do so as well. Late model vehicle systems are much more demanding, in both the amount of technology they posses and in the knowledge necessary to repair them. This work was designed to just that, a step-by step diagnostic approach to OBD II systems. It is also written with the State Inspections in mind. This is in direct response to the increasing adoption of OBD II inspections by most States throughout the country. OBD II repair don’t have to be difficult or cumbersome and knowledge is the key to successful OBD II diagnostics and repair.

"OBD expert, tuner, and author Keith McCord explains system architecture, function, and operation. He shows you how to use a hand-held scanner, connect it to the port connector in the car, and interpret the data. But most importantly, he shows you a practical, analytical, and methodical process for tackling a problem, so you can quickly trace its actual source and fix the root cause and not just the symptom..." -- from page 4 of cover.
