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
Detailed, analytical process helps identify underlying
problems so the entire problem can be fixed.
