Do you want to learn more about Diagnostics?


New Technology

Even “basic” new vehicles are much more complex than their equivalent model from 10+ years ago

Fix the problem

Diagnostic Trouble Codes (DTC’s) are just what the car thinks is happening, maybe not what is actually happening

Component Testing

Understanding how to use multimeters and oscilloscopes for component testing is vital

Our training courses are designed to help you to:


Gain knowledge and confidence


Gain transferable skills


Learn how to use scantools, multimeters and ‘scopes


Learn to interpret live data and waveforms

Basic Auto Electrics & Electronics

  • All technicians would benefit from attending this course, particularly people who would normally avoid working with electrics.
  • Some older technicians may have just attended mechanical training when young and not had formal electrical training.
  • How electricity is produced for vehicles
  • Wiring types for various circuits
  • A/C & D/C differences
  • Measurements, Volts, Amps & Ohms
  • Ohms Law
  • Electrical units and multipliers
  • Circuits, series and parallel
  • Switches and Rheostats
  • Measuring devices
  • Practical Exercises
  • Grounds, and Earth testing
  • Introduction to Sensors and Actuators
  • Fault finding techniques, including short and open circuit testing and measuring high resistances

Scantool Diagnostics & CAN Bus

  • All technicians would benefit from this course, basic trained mechanics will gain the knowledge and insight required to work on modern cars, understanding limitations of equipment types will build confidence to correctly diagnose complex problems on today’s cars.
  • Technicians who wish to be brought up to date on how to diagnose faults on modern vehicles.
  • People who need to know how the system works, to facilitate other areas of work they may need the knowledge.
  • Timeline on introduction of computerisation and vehicle networks
  • Electric fundamentals
  • Understanding Fault Codes and how they are generated
  • Why you do not always get Fault Codes but have problems on the vehicle
  • Sensors and Actuators, what role they play.
  • How data is passed around a vehicle.
  • Understand the difference between Live Data and Graphing
  • CAN BUS explained
  • Why we need and use CAN BUS systems

Engine Component Diagnostics

  • This course is orientated to use oscilloscope with other test equipment. In particular the oscilloscope helps give a good understanding of sensors, actuators and how they operate.
  • Fundamentals of electronic ignition, electronic control systems, electronic fuel injection and idle speed control; with oscilloscope use as a diagnostic aid. With waveform interpretation and understanding made easy.
  • All technicians would benefit from attending this course but it is specifically aimed at technicians who understand the basic principles of electricity and want to improve their diagnostic skills.
  • Anyone who has finally realised that owning a Scan-tool is only halfway there. For people who want to fix the car rather than just find out what is wrong with it.
  • Fundamentals on electronic controls used, focusing on electronic architecture and interaction between sensors and actuators.
  • Background to purpose of Euro 3, Euro 4, Euro 5 and what to expect with Euro 6. Block exemption rulings and roll-out of standardised parts.
  • Detailed coverage of Electronic Fuel Injection both Petrol and Diesel.
  • Air metering devices including vacuum sensors (MAP), hot wire (air mass meter),
  • Karmen Vortex type air flow and vane type air flow meters.
  • Temperature sensors
  • Oxygen sensors (Lambda/O2)
  • Knock sensors16
  • Throttle position sensors (Potentiometers)
  • Engine speed sensors (Crankshaft)
  • Crank/Cam position sensor (Cam sensor)
  • Basic operation and operational decision making priorities.
  • Fuel injectors
  • Idle Speed Control Valves (Rotary and Electromagnetic)
  • Exhaust Gas Recirculation Valves (EGR)
  • PRACTICAL – Implementation of the theory using either delegates own vehicles and test equipment, if required equipment shall be provided for this practical work. Readings can be compared with Scan-tool data
