Automotive Systems Fundamentals
From Shop Safety to EVs — Every System, In Depth
A complete ground-up automotive education covering every system on modern vehicles. 28 modules of real teaching for technicians who want to understand how things actually work — not just how to swap parts. Every system, in depth, zero fluff.
Course Modules
Shop Safety & Professional Standards
Before you touch a car, you need to come home in one piece. This module covers everything that keeps you alive and employed.
Hand Tools, Power Tools & Equipment
Your tools are your livelihood. Know what each one does, when to use it, and how not to break it — or yourself.
Fasteners, Torque Specifications & Thread Repair
A bolt is not just a bolt. Thread pitch, grade, torque sequence, and stretch all matter. Get this wrong and things fall off or break.
How Engines Work — The Four-Stroke Cycle
Everything starts here. If you understand the four strokes, you can diagnose any engine problem. This module builds the foundation.
Engine Mechanical — Block, Head & Valvetrain
The physical components inside the engine. What they do, how they fail, and what the symptoms tell you.
Cooling Systems — How They Work & Why They Fail
An engine produces enough heat to destroy itself in minutes. The cooling system is the only thing standing between normal operation and a melted engine.
Lubrication Systems — Oil Flow & Engine Protection
Oil is the lifeblood of the engine. Understand how it flows, what it does, and what happens when it fails.
Fuel Systems — Fuel Delivery & Injection
From the tank to the injector tip. How fuel gets where it needs to go, at the right pressure, at the right time.
Ignition Systems — From Spark to Combustion
Coils, plugs, timing, and what happens when 40,000 volts meet a compressed air-fuel mixture.
Emission Control Systems — Catalytic Converters, EGR & EVAP
The systems that clean up after the engine. How they work, why they fail, and the codes they set.
Electrical Fundamentals — Voltage, Current & Resistance
The foundation of every electrical diagnosis. If you understand these three concepts, you can diagnose any circuit.
Automotive Circuits — Series, Parallel & Circuit Protection
How circuits are built, how fuses and relays protect them, and what happens when they fail.
Reading Wiring Diagrams & Schematics
The language of electrical diagnosis. Learn to read a schematic like a master tech reads a roadmap.
Starting Systems — Starters, Circuits & Diagnosis
The vehicle will not crank. Is it the starter? The battery? The circuit? Walk the path and find out.
Charging Systems — Alternators, Regulation & Testing
How the alternator keeps the battery charged and the electrical system alive. Testing and diagnosis.
Battery Technology — Conventional, AGM & Lithium
How batteries store energy, how they fail, and how to test them accurately.
Lighting, Accessories & Body Electrical
Headlamps, power windows, door locks, BCM controls — the systems techs troubleshoot every single day.
Manual Transmissions & Clutch Systems
Gear ratios, synchronizers, clutch hydraulics, and why they still matter in modern vehicles.
Automatic Transmissions — Theory & Operation
Torque converters, planetary gearsets, solenoids, and adaptive learning. How the transmission decides what gear to be in.
Drivetrain — Driveshafts, Differentials & CV Joints
Transferring power from the transmission to the wheels. U-joints, CV joints, ring and pinion, limited-slip.
Brake Systems — Hydraulic Fundamentals & Friction
Master cylinders, calipers, pads, rotors, and the physics of stopping a 4,000-pound vehicle.
Electronic Brake Systems — ABS, Traction Control & Stability Control
How the computer prevents wheel lockup, wheelspin, and loss of control. Sensors, modulators, and diagnosis.
Steering Systems — Rack & Pinion, Power Steering & EPS
How the steering system converts driver input to wheel direction. Hydraulic vs electric power assist.
Suspension & Wheel Alignment
Springs, struts, control arms, and the geometry that keeps the vehicle pointing straight and riding smooth.
HVAC — Heating, Ventilation & Air Conditioning
Refrigerant cycle, blend doors, compressor operation, and the electrical controls that tie it all together.
Hybrid & Electric Vehicle Fundamentals
High-voltage batteries, inverters, electric motors, regenerative braking, and safety procedures.
Diesel Engine Systems
Compression ignition, HPCR fuel systems, turbocharging, DPF, DEF, and diesel-specific diagnostics.
ADAS — Advanced Driver Assistance Systems
Cameras, radar, lidar, lane keep, adaptive cruise, automatic emergency braking, and calibration requirements.
CAN Bus & Vehicle Communication Networks
How modules talk to each other. CAN high, CAN low, terminating resistors, gateways, and U-code diagnosis.
