Whether you're a new Service Advisor or aspiring Technician, this glossary is your guide to understanding the language of the automotive industry.



When you embark on a journey in the automotive industry, it can sometimes feel like you've entered a world with its own language. From engine components to diagnostic tools, there are a plethora of terms and concepts that every automotive Service Advisor should be familiar with. In this automotive training glossary, we will demystify some of the most important terms and concepts you'll encounter during your training and future career. Whether you're a new Service Advisor or aspiring Technician, this glossary is your guide to understanding the language of the automotive industry.

  1. Internal Combustion Engine (ICE): The most common type of engine found in vehicles, where fuel (usually gasoline or diesel) is burned within the engine to create power.
  2. Transmission: The system that transfers power from the engine to the wheels, allowing the vehicle to change speed and direction.
  3. Differential: A device that splits the power from the engine between the two wheels on an axle, enabling them to rotate at different speeds when turning.
  4. Spark Plug: An electrical component that ignites the air-fuel mixture in the engine's cylinders.
  5. Carburetor: An older engine component that mixes air and fuel for the engine to use. Most modern vehicles now use fuel injection systems.
  6. Fuel Injection: A system that sprays fuel directly into the engine cylinders, providing better fuel efficiency and performance compared to carburetors.
  7. Chassis: The framework of a vehicle, to which all major components like the engine, transmission, and suspension are attached.
  8. Suspension System: The system of springs, shock absorbers, and linkages that connects the vehicle's wheels to its chassis, providing a comfortable ride and control over the vehicle.
  9. OBD (On-Board Diagnostics): A system that monitors and reports the health and status of a vehicle's various systems, helping technicians diagnose problems.
  10. Horsepower (HP): A unit of measurement for engine power, indicating the engine's ability to perform work.
  11. Torque: The rotational force produced by the engine, which is essential for acceleration and towing capacity.
  12. ABS (Anti-lock Braking System): A safety system that prevents the wheels from locking up during hard braking, maintaining steering control.
  13. Catalytic Converter: A device that reduces harmful emissions in the exhaust gases by converting them into less harmful compounds.
  14. HVAC (Heating, Ventilation, and Air Conditioning): The system that controls a vehicle's climate, providing heating, cooling, and ventilation.
  15. ASE (Automotive Service Excellence) Certification: A standard certification for automotive technicians, demonstrating their competence in various areas of automotive repair and maintenance.
  16. Diagnostic Trouble Code (DTC): A code generated by the vehicle's computer to indicate a problem or malfunction in one of its systems.
  17. SAE (Society of Automotive Engineers): A professional organization that sets standards for automotive engineering and technology.
  18. Oversteer and Understeer: Handling characteristics of a vehicle; oversteer occurs when the rear tires lose traction, causing the vehicle to turn more sharply, while understeer is when the front tires lose traction, causing the vehicle to plow straight ahead during a turn.
  19. Hybrid Vehicle: A vehicle that combines an internal combustion engine with an electric motor to improve fuel efficiency and reduce emissions.
  20. EV (Electric Vehicle): A vehicle powered entirely by electricity, with no internal combustion engine.

This glossary is just the beginning of your journey into the world of Service Advising. As you delve deeper into your work and gain practical experience, these terms and concepts will become second nature, helping you excel in your automotive career. Understanding this terminology is a vital first step in becoming a skilled and knowledgeable automotive professional.
