From Hardware Setup to Measurement Mastery
KG ProTech’s Fault Simulator delivers an integrated platform that enables instructors to replicate electrical and electronic faults safely, helping learners understand system responses and diagnostic logic.
The KG Hardware ecosystem — including the KG Box, KG Auto Cables, and KG Terminals — operates as a unified simulation and testing system.
At its center, the KG Box functions as a universal fault simulator, allowing controlled creation of open circuits, short circuits, and voltage variations within a vehicle’s network. Connected via KG Auto Cables, it bridges the ECU and engine circuits, enabling safe, live interactions.
Its modular design supports quick setup and adaptation to multiple training modules. The built-in battery provides up to four hours of operation, ensuring reliability throughout practical sessions.
This configuration allows instructors to replicate real diagnostic conditions, giving students hands-on experience identifying and analyzing simulated faults.
KG Terminals: Precision Measurement and Signal Analysis
Once the simulation is active, KG Terminals provide access points for accurate electrical measurements on both ECU and engine sides. Using a multimeter, learners can observe voltage drops and signal variations as faults are introduced.
The process reinforces proper measurement techniques and interpretation skills. Open-circuit simulations demonstrate clear voltage differences at the ECU side while healthy signals remain stable on the engine side — illustrating how faults propagate through circuits.
A Complete Diagnostic Training Platform
Together, KG Hardware and KG Terminals form a comprehensive, hands-on solution for automotive diagnostics training. The system bridges theory and practice, helping learners develop core skills in sensor testing, fault tracing, and signal analysis.
By offering repeatable, realistic fault behavior, KG ProTech’s Fault Simulator enhances instructional quality and standardization in automotive education.
