Automotive Computer Controlled Systems By: Allan Bonnick ISBN-10: 0750650893 ISBN-13: 9780750650892 Publisher: Butterworth-Heinemann - 2001-04-10 Paperback | 272 Pages Annotation: 'Automotive Computer Controlled Systems' explains the fundamental principles of engineering that lie behind the operation of vehicle electronic systems. Having obtained this knowledge, the reader will be able to make full use of the diagnostic equipment which is currently available. The book builds on the concepts contained in Vehicle Electronic Systems and Fault Diagnosis and gives clear steps to fault diagnosis and subsequent repair of the vehicle's electronic systems. The author discusses electronics only within the context of the vehicle systems under consideration, and thus keeps theory to a minimum. Allan Bonnick has written articles for several transport/vehicle journals and carries out consultancy work for the Institute of Road Transport Engineers. In addition, he has had many years teaching experience and is ideally placed to write this informative guide.

Discusses electronics and computer technology of vehicle systems from a practical rather than theoretical standpoint, and gives step-by-step instructions on fault diagnosis and repair of computer controlled systems. Principles are discussed through examples, avoiding unnecessary theory and mathematics. Bonnick is a vehicle engineering education and training consultant. Annotation c.
