- Designed for testing wiring circuits and enabling quick setup to support technicians in accurate vehicle problem diagnosis. - Its variable resistors simulate coolant temperature sensor signals and throttle position sensor signals to the vehicle ECU, helping verify ECU behavior and avoid unnecessary part replacements. - Equipped with two sets of LED lights to monitor the reverb effect, photoelectric signals, nozzles, transmission gear electromagnetic valves, and control signals. - The included SRS connector can simulate airbag deployment and seat belt pretensioner operation to avoid accidental deployment or misdiagnosis. - Use scenario: In a workshop, diagnose ECU wiring and sensor faults by adjusting the variable resistors to reproduce real sensor conditions and observe ECU responses without swapping parts. - Use scenario: Test transmission related signals by monitoring LED indicators while simulating gear-related sensor and valve activity. - Use scenario: Safely verify safety system procedures by using the SRS connector to emulate airbag and seat belt pretensioner events during diagnostic tests.
