Reading and Analyzing Live Data System Scanning and Testing Procedures Advanced Troubleshooting and Fault Diagnosis

Learners will understand how to perform full system scans and run functional tests across different vehicle systems such as engine, transmission, and ABS. The lesson includes step-by-step procedures for accurate system evaluation and verification.

This lesson covers how to access and interpret live data from vehicle sensors in real time. Learners will develop the ability to identify normal and abnormal readings, use data streams effectively, and make informed diagnostic decisions.

This lesson covers how to access and interpret live data from vehicle sensors in real time. Learners will develop the ability to identify normal and abnormal readings, use data streams effectively, and make informed diagnostic decisions.

This lesson focuses on using SCN diagnostic tools to perform active (bi-directional) tests. Learners will understand how to command and control vehicle components such as actuators, sensors, and systems in real time. The lesson explains how to verify component functionality, isolate faults, and confirm repairs by directly interacting with vehicle systems through the scan tool.

TPMS Sensor Programming and Calibration

This lesson focuses on Tire Pressure Monitoring System (TPMS) sensors and how to program, relearn, and calibrate them using SCN diagnostic tools. Learners will understand how TPMS works, how to register new sensors, reset warning lights, and ensure accurate tire pressure readings. The lesson also covers common TPMS faults and how to diagnose and resolve sensor-related issues effectively.

This lesson introduces the fundamentals of testing and diagnosing electric vehicle (EV) systems using SCN diagnostic tools. Learners will understand how to safely work with high-voltage components, monitor battery performance, and analyze key EV parameters such as state of charge, voltage levels, and system health. The lesson also covers identifying faults in electric drivetrains, charging systems, and battery management systems, ensuring accurate and safe diagnostics for modern electric vehicles.

This lesson focuses on professional diagnostic strategies for identifying root causes of complex vehicle issues. Learners will apply structured troubleshooting methods, analyze electrical and electronic faults, and work through real-world diagnostic scenarios.
