PREFACE:

In this third edition some of the older technology has been removed and modern technology to include Level 3 topics has been included. Much emphasis has been placed on fault diagnosis because it is such an important part of a modern automotive technician’s work.


 The careful consideration of fault diagnosis that is undertaken in a range of examples in this edition shows how a methodical approach to fault diagnosis, based on good knowledge of automotive systems, can lead to success. As an example, the ECU may report the fault code P0301 that tells us that there is a misfire in number 1 cylinder. The misfire may be caused by one or more factors, including : 

- Ignition problem, defective spark plug, defective HT cables, defective direct ignition coil, etc.

 - Poor compression, badly seating valve, leaking gasket, worn or broken piston rings.

- Incorrect mixture in that cylinder, air leak, defective petrol injector.


It is clear that good ignition in a single cylinder is dependent on many factors, which must be taken into account when considering what action to take. Faults in some of these other areas may also be recorded in fault codes, but others will not. 


To locate causes of faults in these other areas may require use of specialist equipment, and reference to manuals and circuit diagramsethese factors are covered in detail in several of the examples in this book. The methodical six-step approach is highlighted as a sound basis for successful fault diagnosis.


It is the responsibility of every person involved in work to protect their own safety and that of any other persons who may be affected by their activities. At the basic level this means that everyone must work in a safe manner and know how to react in an emergency. 


Personal cleanliness issues such as regular washing, removal of substances from skin, use of barrier creams, use of protective clothing and goggles and gloves, etc. are factors that contribute to one’s well being. 


Behaving in an orderly way, not indulging in horseplay, learning how to employ safe working practices, and helping to keep the workplace clean and tidy are all ways in which an individual can contribute to their own and others’ health and safety at work.


The information contained in this book does not attempt to provide full coverage of all safety and health issues. The information provided merely draws attention to some safety issues, and is not intended to cover all areas of safety. 

Readers should ensure that any education course, training scheme, apprenticeship or other training arrangement does contain all necessary safety training
