    The Electronic Control Unit and other electronic controls are connected to every major system of a car built within the past 15 years, yet when there is a problem or an error code, many do not know how to go about fixing the problem. With this book, an affordable hand held scanner and other common tools, the average enthusiast can diagnose and fix most common problems, rather than bringing the vehicle to a dealership for repair at shop rates of $100 per hour or more. Keith McCord recounts the history of automotive onboard diagnostic systems and the creation of the rudimentary OBD I system and the development as well as the evolution of OBD II. Currently, OBD-II (OnBoard Diagnostic II) is the standard of the industry, and this book provides a thorough explanation of this system. It details its main features, capabilities, and characteristics. It shows how to access the port connector on the car, the serial data protocols, and what the serial data means. To understand the diagnostic codes, the numbering system is defined and a table of common DTCs is shown. But most importantly, McCord provides a thorough process for troubleshooting problems, tracing a problem to its root, explaining why DTCs may not lead to the source of the underlying problem, and ultimately resolving the problem. Almost anyone can hook a scan tool up to the serial port and read the error, but the key to fixing the problems is using an effective troubleshooting process that resolves all the issues that may be contributing or creating the problem. McCord provides sound procedures, insight, and information for resolving most ECU and computer control problems at home with affordable consumer-grade scanners.

  • Explains operation and function of on board diagnostic systems, and thoroughly covers the scanners, tools, and error codes.
  • Provides a methodical step-by-step approach to troubleshooting and resolving computer control system problems.
  • Detailed, analytical process helps identify underlying problems so the entire problem can be fixed.
