Key Features + Benefits

Built for Modern Automotive Electrical Education

Teaches fundamentals of electrical circuits, automotive systems, starting/charging systems, multiplexing (J1939 + OBD-II), DTCs, sensor outputs, LED vs. incandescent lighting, and more.

Interactive Fault Generation for Real-World Diagnostics

Instructors can create electrical faults manually or via the onboard touchscreen computer, allowing students to diagnose true-to-life failures on a complete automotive network.

Learn Multiplexing + CAN-BUS Communication

Students understand how modules communicate, how messages travel across a network, and how failures occur in J1939/OBD-II systems, including viewing messages in real time.

Full Starting + Charging System Simulation

Includes starter motor, alternator charging system, battery current sensors, cold/hot start modes, and testing of battery, crank, and load current.

Automotive Sensors Built Into the Panel

TPS, coolant temperature, oil pressure, hall-effect speed sensors, magnetic sensors, and more are mounted and ready for testing and signal analysis.

Banana-Plug Test Points Throughout the System

Students gain safe, repeatable access to circuits for voltage, resistance, current, and signal testing, reinforcing best diagnostic practices.

Teaches Students to Avoid Unnecessary Module Replacement

Learners build real troubleshooting skills, not “parts changing” habits, saving employers time and cost.

Colleges Benefit From Industry-Aligned, Safe Training Tools

Attract students, reduce accidents, and deliver job-ready graduates while using systems purpose-built for safety and instructional clarity.
