This two day course follows on from Vehicle Electrical Principles.

The course is aimed at vehicle mechanics, technicians and apprentices who want to develop their knowledge of vehicle electrical systems and improve their electrical fault finding skills.

Course content covers the following main subjects:

Fault finding 1

Day 1

  • Pre assessment – review electrical knowledge
  • Overview vehicle electrical system developments
  • The approach to diagnostics
  • Tools and equipment requirements
  • Digital multi meters
  • Oscilloscopes
  • Scan tools
  • Relays
  • Workshop practical tasks
  • Review and summary day 1

Day 2

  • Review day one
  • Electrical system functions
  • Bus networking principles
  • Wiring diagrams and technical information
  • Fault finding routines
  • Workshop practical tasks – fault diagnosis
  • End of course assessment

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 for a Professional Development Certificate – PDC. You will also receive a Certificate of Professional Development from AK Automotive in recognition of your attendance.

Pre requisites

Candidates must have a motor industry or other relevant technical background (eg, ex R.E.M.E.).

Those with little or no prior electrical knowledge would benefit from first attending the Vehicle Electrics Module 1 – Electrical Principles course.

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.
