It can turn off the MIL light, clear diagnostic trouble codes (DTCs), and reset monitors. The device supports the new extended sensor list (SAE J1979 2007) and provides access to live data streams from engine and transmission modules, including O2 sensor data. It also stores freeze-frame data for later evaluation and includes I/M Readiness functionality with color-coded LEDs to assist with emissions testing preparation.
