Automotive Electronics Course

Lesson 1 • Reading and Interpreting Wiring Diagrams

Teaches symbol conventions, ground references, splice locations, and current-flow tracing on OEM diagrams. Students can navigate multi-page schematics to isolate a target circuit.

Lesson 2 • Core Electrical Concepts for Vehicles

Covers Ohm's Law, power calculations, and series/parallel circuits as applied to automotive loads. Establishes the quantitative foundation for all subsequent diagnostic work.

Lesson 3 • Test Equipment and Measurement Techniques

Introduces the digital multimeter, test light, and logic probe for safe, accurate measurements. Correct probe placement and meter settings prevent component damage and false readings.

Lesson 4 • Automotive Wiring and Connector Systems

Examines wire gauges, insulation ratings, terminal types, and connector locking mechanisms. Proper connector knowledge prevents misdiagnosis caused by poor contact resistance.

Lesson 1 • Alternator Operation and Output Testing

Explains rotor, stator, rectifier, and voltage regulator functions within the alternator assembly. Output testing confirms whether charging voltage and current meet vehicle specifications.

Lesson 2 • Charging System Fault Diagnosis

Uses voltage drop testing and oscilloscope waveforms to pinpoint charging faults beyond simple output checks. Systematic diagnosis distinguishes alternator, wiring, and regulator failures.

Lesson 3 • Lead-Acid and AGM Battery Technology

Compares flooded, AGM, and EFB battery chemistries, covering plate construction and electrolyte behaviour. Chemistry knowledge guides correct charging rates and replacement specifications.

Lesson 1 • Starter Motor Design and Operation

Covers armature, field windings, brushes, and overrunning clutch function in conventional and gear-reduction starters. Component knowledge supports accurate failure-mode identification.

Lesson 2 • Cranking Circuit Wiring and Switches

Maps the ignition switch, neutral safety switch, clutch switch, and relay paths that enable starter engagement. Understanding inhibitor logic prevents misdiagnosis of no-crank conditions.

Lesson 3 • No-Crank Fault Diagnosis Procedure

Applies a structured voltage drop and signal-tracing method to distinguish battery, wiring, switch, and starter faults. Systematic steps reduce diagnostic time and misdiagnosis.

Lesson 1 • Oxygen and Exhaust Gas Sensors

Explains zirconia and wideband lambda sensor operation, heater circuits, and closed-loop fuel control interaction. Correct waveform interpretation distinguishes sensor faults from fuel system issues.

Lesson 2 • Actuator Types and Control Methods

Covers solenoids, stepper motors, DC motors, and PWM-controlled actuators used for fuel, air, and emission management. Actuator testing confirms coil resistance, duty cycle, and mechanical response.

Lesson 3 • Temperature and Pressure Sensors

Covers NTC thermistors, MAP sensors, and piezoelectric pressure transducers used throughout the powertrain. Resistance-temperature curves and pressure-voltage relationships guide accurate diagnosis.

Lesson 4 • Position and Speed Sensors

Examines Hall-effect, variable reluctance, and potentiometer-based sensors for crankshaft, camshaft, and throttle position. Waveform shape and frequency confirm correct sensor operation.

Lesson 1 • OBD-II System Architecture and Protocols

Explains the data link connector, communication protocols, and monitor structure of the OBD-II standard. Protocol knowledge enables correct scan tool selection and data interpretation.

Lesson 2 • Live Data Streaming and PID Analysis

Teaches PID selection, graphing, and snapshot capture to correlate sensor behaviour with fault symptoms. Efficient PID grouping reduces diagnostic time on intermittent faults.

Lesson 3 • Advanced OBD Modes and Network Scanning

Explores OBD modes 6 through 9 for component monitoring data and VIN verification. Network scanning identifies modules with faults beyond the powertrain control system.

Lesson 4 • Diagnostic Trouble Code Interpretation

Decodes P, B, C, and U code structures and distinguishes confirmed, pending, and permanent codes. Correct code classification prevents unnecessary repairs and guides root-cause analysis.

Lesson 1 • Ignition System Types and Diagnosis

Compares distributor, coil-on-plug, and coil-near-plug ignition architectures and their primary/secondary circuits. Waveform analysis identifies misfires, weak coils, and secondary insulation breakdown.

Lesson 2 • Fuel Delivery and Pressure Regulation

Covers fuel pump circuits, pressure regulators, and returnless fuel system designs for port and direct injection. Correct pressure testing procedures prevent misdiagnosis of injector vs. pump faults.

Lesson 3 • ECM Architecture and Input Processing

Explains ECM power supplies, keep-alive memory, and how sensor inputs are processed into control decisions. Understanding ECM architecture prevents misdiagnosis of sensor vs. controller faults.

Lesson 4 • Fuel Trim and Driveability Diagnosis

Uses short-term and long-term fuel trim data alongside oxygen sensor waveforms to identify rich/lean root causes. Systematic data analysis reduces unnecessary parts replacement.

Lesson 1 • LIN Bus and Local Interconnect Networks

Explains LIN master-slave architecture, break field synchronisation, and typical body subsystem applications. LIN diagnosis requires understanding single-wire signal characteristics and checksum errors.

Lesson 2 • Body Control Module Functions and Faults

Maps BCM control of lighting, wipers, windows, locks, and accessory power circuits. BCM fault diagnosis combines scan data, wiring checks, and module programming verification.

Lesson 3 • CAN Bus Operation and Diagnosis

Covers CAN-H and CAN-L differential signalling, dominant/recessive states, and oscilloscope waveform analysis. Resistance and waveform tests isolate open, short, and termination faults on the bus.

Lesson 4 • Multiplex Network Fundamentals

Explains why multiplexing replaced point-to-point wiring and how nodes share data on a common bus. Network topology knowledge is prerequisite for all communication fault diagnosis.

Lesson 1 • Traction Control and Stability Control Systems

Explains how yaw rate, lateral acceleration, and steering angle sensors enable ESC intervention. Understanding sensor fusion logic prevents misdiagnosis of stability system faults.

Lesson 2 • ABS and Wheel Speed Sensor Systems

Covers ABS modulator hydraulics, wheel speed sensor signal processing, and reluctor ring inspection. Accurate wheel speed data is the foundation for all vehicle dynamics control systems.

Lesson 3 • Supplemental Restraint System Diagnosis

Covers airbag module, clock spring, impact sensor, and squib circuit testing with safety precautions. SRS diagnosis requires strict disarming procedures to prevent accidental deployment.

Lesson 4 • ADAS Sensor Technologies and Calibration

Examines radar, camera, ultrasonic, and lidar sensor technologies used in collision avoidance and lane-keeping systems. Post-repair calibration procedures ensure sensor alignment meets system accuracy requirements.
