Haynes Automotive Diagnostic Fault Codes

Engine management and fuel injection system fault codes for all popular petrol cars and light commercial vehicles. This book Is devoted to the gathering on fault codes, and to the understanding and testing at the sell-diagnosis element of the modern engine management system. This Automotive Diagnostic Fault Code Techbook is a companion volume to the Haynes Engine Management and Fuel Injection Systems Manual, and for a complete understanding of the modern engine management system, the content of both books should be examined.

The book first gives a technical overview of self-diagnosis.O there Chapters describe test equipment and general test routines for individual components which may be indicated to tx? detective by the presence of a stored fault code. Finally, each vehicle manufacturer is given a specific Chapter with a comprehensive list of fault codes, details of how to obtain codes, and other relevant information. Even If the reader has no intention of actually attempting to investigate faults on his or her own vehicle, the look still provides valuable insight iito self-diagnosis.

On the other hand, if you relish the task of electronic fault diagnosis, this book will provide you with in the background knowledge necessary to test the components and circuits on your engine. Generally, we describe how lo dangle faults using simple tools and equipment, which will be available from most good automotive parts retailers.

We also mention where the use more specialized equipment is necessary, and describe some of the common routines used by the professional garage trade.

The vehicle manufacturers may not in fact a number of our tests and routines. In the main, this will be because the manufacturer’s test routines are becoming more focused on their own dedicated test equipment which is not generally available outside of a main dealer network In almost all instances, our own tests follow well-defirled testing methods taught in independent training schools, and used by many modern technical specallsts. We mainly describe simple testing methods that are possible of the ubiquitous digital muhi-meter (DMM).

Refer to the companion volume (Haynes Engine Management Techbook) for a description of the operation and test procedures of the modern engine managment system. Our test procedures ore necessarily generic. However, in many cases, following our procedures in conlunction with a good wiring diagram will reveal the reason lor most faults.

The routine and test methods which we describe are perfectly safe to carry out on electronic systems, so long as certain simple rules are observed. These r u l e are actually no more than the observation of good electrical practice. 8e aware that damage to highly-expensive electronic control modes can result from rules.

Refer to the Warnings sector in the Reference section at the back of this book + these warnings will be repeats/referred to where necessary in various procedures. Throughout Furow, the USA and the Far East, the various manufacturan tend to use their own particular terms to describe a particular component. Of course, all these terms tend to be different, and the problem is exacerbated by translation into different languages. This often leads to confusion when several terms are used to describe essentially the same component. There been severs! One such does exist (J1930), but it seems unlikely that manufacturers will adopt this part standard, and we are not sure that the used are that meaningful anyway. Thus, Lk t m s u sad in this book will follow those w t k are commonly used in the UK. To redux confusion, we will apply these t e r n for !be wide range of manufacturers covered in book, and any commonly-used alternate will be listed in the Reference section at the end.
