Launch's three modular interfaces for the GDS, the Sensorbox Simulator, Batterybox Tester and Scopebox 4-channel Oscilloscope greatly expand the diagnostic capabiltiy for the GDS scan tool. The SensorBox module also allows users to create/modify all kinds of signal parameters such as coolant temperature, mass air flow, throttle position and more. The Batterybox module utilizes the latest in battery testing technologies. With the GDS ScopeBox, users can quickly capture suspect/intermittent signals for waveform analysis.
