- DataStream: Displays live data parameters from the vehicle's sensors in real-time. This can be viewed graphically for better analysis.
- Freeze Frame: When an emission-related fault occurs, certain vehicle conditions are recorded by the on-board computer. This information is referred to as freeze frame data.
- O2 Sensor Test: Retrieves and views O2 sensor test results for most recently performed tests from the vehicle's on-board computer.
- On-Board Monitoring: This function can be utilized to read the results of on-board diagnostic monitoring tests for specific components/systems.
- Evap System Test: Initiates a leak test for the vehicle's EVAP system.
- Vehicle Information: Displays the Vehicle Identification Number (VIN), Calibration Verification Number (CVN), and other information.
- Retrieve Generic (P0, P2, P3, and U0), manufacturer specific (P1, P3, and U1) codes and pending codes.
