Auto Technician Course

Lesson 1 • Professional and Environmental Standards

Covers workplace conduct, waste disposal, and environmental compliance expectations. Prepares students to meet shop standards from day one.

Lesson 2 • Automotive Terminology and Systems Overview

Defines key vocabulary and introduces the major vehicle systems. Shared language enables accurate diagnosis and clear communication throughout the course.

Lesson 3 • Tools and Equipment Identification

Introduces hand tools, power tools, and shop equipment by name and function. Correct tool selection is prerequisite to every repair procedure in this course.

Lesson 4 • Career Paths in Auto Service

Covers technician roles, certification levels, and shop hierarchy. Establishes industry context before hands-on work begins.

Lesson 1 • Routine Engine Inspection Procedures

Applies lubrication, cooling, and intake knowledge to a structured multi-point inspection. Students complete a full underhood inspection checklist.

Lesson 2 • Four-Stroke Engine Operation

Explains intake, compression, power, and exhaust cycles with supporting components. Provides the mechanical foundation required for all engine diagnosis chapters.

Lesson 3 • Cooling System Operation and Service

Teaches coolant flow, thermostat function, and radiator operation. Cooling system health directly affects engine longevity covered in later chapters.

Lesson 4 • Air Intake and Exhaust Systems

Describes airflow from filter to exhaust outlet and the role of each component. Connects to fuel and emissions topics introduced in the next chapter.

Lesson 1 • Ignition System Fundamentals

Explains primary and secondary ignition circuits, coils, and spark plugs. Ignition knowledge is essential for diagnosing misfires addressed later in this chapter.

Lesson 2 • Fuel System Components and Operation

Covers fuel tank, pump, injectors, and pressure regulation. Understanding fuel delivery is prerequisite to diagnosing no-start and performance faults.

Lesson 3 • Electronic Fuel Injection Systems

Introduces throttle body and port injection operation controlled by the engine control module. Builds the sensor-and-actuator framework used in the diagnostics chapter.

Lesson 1 • Battery, Starting, and Charging Systems

Covers battery testing, starter circuit diagnosis, and alternator output verification. These high-current systems are among the most frequent electrical complaints.

Lesson 2 • Wiring Repair and Circuit Protection

Teaches splice repair, connector replacement, and fuse/relay diagnosis. Students perform hands-on wiring repairs to restore circuit function.

Lesson 3 • Electrical Theory for Technicians

Covers voltage, current, resistance, and Ohm's Law in automotive context. This theoretical base is required before any circuit testing in subsequent sections.

Lesson 4 • Reading Automotive Wiring Diagrams

Explains schematic symbols, circuit numbering, and connector identification. Diagram literacy is required for efficient fault isolation in all electrical repairs.

Lesson 1 • Drum Brake Inspection and Service

Teaches shoe adjustment, wheel cylinder inspection, and drum measurement. Drum brakes remain common on rear axles and parking brake systems.

Lesson 2 • Hydraulic Brake System Principles

Explains Pascal's Law, master cylinder operation, and brake fluid properties. Hydraulic theory underpins every brake service procedure in this chapter.

Lesson 3 • Disc Brake Inspection and Service

Covers caliper operation, pad measurement, and rotor resurfacing or replacement. Disc brakes are the primary stopping system on most modern vehicles.

Lesson 4 • Parking Brake and Brake Pedal Adjustment

Covers cable adjustment, electronic parking brake operation, and pedal height/free-play settings. Proper adjustment ensures legal and functional parking brake performance.

Lesson 1 • Performing a Four-Wheel Alignment

Applies alignment theory using computerized alignment equipment to meet manufacturer specifications. Students complete a full alignment and document results.

Lesson 2 • Steering System Operation and Service

Covers rack-and-pinion and recirculating-ball steering, plus power assist systems. Steering service directly affects vehicle control and customer safety.

Lesson 3 • Suspension System Types and Components

Identifies independent and solid-axle suspension designs and their components. Component recognition is prerequisite to inspection and replacement procedures.

Lesson 4 • Ball Joints, Bushings, and Wheel Bearings

Teaches wear measurement and replacement of load-bearing suspension joints. These components directly affect alignment angles and tire wear patterns.

Lesson 1 • Automatic Transmission Fundamentals

Explains torque converter operation, planetary gearsets, and hydraulic control circuits. Foundational knowledge required before fluid service and fault diagnosis.

Lesson 2 • Differential and Transfer Case Service

Covers open and limited-slip differential operation, fluid service, and transfer case basics. Rear and four-wheel-drive systems require these service skills.

Lesson 3 • Diagnosing Drivetrain Noise and Vibration

Applies component knowledge to systematic noise and vibration diagnosis using road test and inspection techniques. Students isolate faults to specific drivetrain components.

Lesson 4 • Driveshaft and CV Axle Service

Teaches U-joint inspection, driveshaft balance, and CV axle boot and joint replacement. Drivetrain vibration diagnosis depends on these inspection skills.

Lesson 1 • Sensor Diagnosis and Testing

Teaches testing of oxygen sensors, MAP sensors, coolant sensors, and crankshaft position sensors. Accurate sensor diagnosis prevents unnecessary component replacement.

Lesson 2 • Fuel Trim and Mixture Diagnosis

Applies scan data to diagnose rich and lean conditions using short-term and long-term fuel trim values. Fuel trim analysis is a core driveability diagnostic skill.

Lesson 3 • Driveability Complaint Diagnosis Strategy

Integrates all prior diagnostic skills into a structured complaint-to-repair workflow. Students complete end-to-end diagnosis on complex multi-system faults.

Lesson 4 • Exhaust Emissions and Evaporative Systems

Covers emissions monitor readiness, evaporative system operation, and leak detection. Emissions compliance is required for vehicle registration in most markets.
