Vehicle Electrical Fault Finding Techniques is a two day course.

This course follows on from Vehicle Electrical Principles. It 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.

The course covers the following main subjects:

Fault finding 1Day 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.

Further development

After successfully completing this course, you may like to progress to the following courses:


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.
