This is a two day course for vehicle mechanics, technicians and apprentices who want to improve their electrical fault finding skills.

The course follows on from Vehicle Electrical Principles and explains how to make more effective use of diagnostic tools, oscilloscope and multi meter in conjunction with wiring diagrams and technical information when fault finding vehicle electrical systems.

Fault finding 1

During the course you will learn how to read and analyse wiring diagrams using Autodata, to understand how vehicle electrical systems work, and make more informed decisions when taking test measurements.

You will learn how to use the diagnostic scan tool’s functions more effectively to investigate system functions and fault symptoms.

You will learn how to combine your knowledge with use of test equipment and wiring diagrams to formulate logical fault finding test routines.

The course comprises a range of workshop based practical sessions using live vehicles & diagnostic tools supported by classroom based presentations and technical discussions. At the start of the course, you will receive a fully illustrated set of course notes.

Fault Finding 2

The course explains the operation and layouts of electrical systems and includes an overview of bus networked systems.

By the end of the course, you will have gained a detailed knowledge and understanding of modern vehicle electrical systems that will be useful to you in carrying out cost effective diagnostic repairs.

Assessment and accreditation

Assessment is on going throughout the course and the course has certified recognition from the IMI as a Quality Assured Programme – QAP at Level 3. You will also receive a Certificate of Professional Development from AK Automotive in recognition of your attendance.

Vehicle Electrical Fault Finding Techniques

Introduction (extract from course notes)

The complexities of modern vehicle electronic systems present challenges for even the most experienced workshop technicians.

Vehicle electrical systems now often comprise several multi-function control modules located around the vehicle. Systems have become decentralised with functions distributed between individual modules. Some modules also control the vehicle’s voltage distribution and power management systems.

Bus network technologies such as CAN, LIN and FlexRay have revolutionised electrical systems layouts. They have brought about increased levels of functionality, programming and configuration capabilities. Even base level equipment such as lights, horns, wipers, instrumentation and convenience systems are controlled in this way. Bus networks are yet another factor to be considered when evaluating vehicle system faults.

Such factors place further demands upon the knowledge and expertise of vehicle technicians, who must now be familiar with a wider range of diagnostic tools, systems knowledge and fault finding techniques. The diagnostic scan tool is an essential item for carrying out fault finding, to be used in conjunction with wiring diagrams and other test instruments such as a multi meter and oscilloscope.

With this in mind, the most important things a technician really needs to successfully diagnose modern vehicles are a good working knowledge of how electrical systems work, competency with use of diagnostic equipment, wiring diagrams and technical information, and to adopt logical and methodical test routines.

The aim of this course is to present a practical approach to vehicle electrical fault finding and diagnostic techniques. During the course, you will gain knowledge and skills that will enable you to carry out more cost effective fault finding and diagnosis.

By the end of the course you will have gained a more in-depth knowledge of vehicle electrical systems and be more confident when diagnosing electrical faults.
