In Introduction to On-Board Diagnostics (OBD II) readers will learn how this complex system functions and be provided with valuable reference material for diagnosing and troubleshooting its many components and circuits. This book provides a simple, logical approach to explain the operation of the OBD II system and will teach the reader how to quickly spot problems and identify components that are not functioning correctly. In addition, the interrelationships between the fuel delivery, emission control, ignition, and accessory systems are clearly addressed and explained. CAM data is also included.
