Description
For more than 30 years, cars and trucks have carried onboard diagnostics (OBD), which monitor and adjust major systems, including engine, drivetrain, fuel, and more. Many think that repairing or tuning the current system (OBDII) is a black art or a computer science, and that there is no way to diagnose and fix computer control-system problems at home with affordable tools. But, that is simply not true.
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.
Automotive Diagnostic Systems includes definitions of diagnostic trouble codes and a table of common DTCs. McCord reveals the intricacies of diagnosing the system, the importance of fixing component DTCs first, one- and two-trip codes, how the PCM erases DTCs, and how you can have DTCs stored in memory with no MIL on, among many other common issues.. As a result, you learn how to resolve a range of common OBD-II problems, such as engine misfires, shorts and opens, out-of-tune fuel trims, dead catalysts, emissions leaks, low voltages, failed oxygen sensors, and much more. But it also covers fuel injectors, ignition systems, chassis sensors, and various other sensors and actuators.
