• Live Data: Displays graphical live data from vehicle computer modules and allows viewing of vehicle operating parameters at the moment a DTC is detected.
• DTC Lookup: Provides a built-in DTC lookup library with code definitions and detailed explanations to simplify the analysis and repair process.
• Record Data & Playback: Records vehicle module Parameter Identification (PID) data to help diagnose intermittent vehicle problems, saves data files to the Micro SD card, and supports playback of recorded data.
• Freeze Frame: Displays vehicle operating parameters at the moment a DTC is detected, including parameters such as engine speed (RPM), engine coolant temperature (ECT), and vehicle speed sensor (VSS).
• I/M Readiness: Checks the operation of the Emission System on OBD II-compliant vehicles and reads I/M readiness status for state emissions compliance.
• O2 Monitor Test: Displays the latest O2 sensor test results in graphical form for troubleshooting fuel-efficiency and vehicle-emission-related problems.
• On-Board Monitor Test: Retrieves and displays test results for emission-related powertrain components and systems, including continuously and non-continuously monitored systems.
• Component Test: Allows initiating a leak test for the vehicle's EVAP system by commanding the vehicle's on-board computer to start the test.
• Vehicle Information: Retrieves Vehicle Identification Number (VIN), Calibration ID Nos. (CINs), Calibration Verification Nos. (CVNs), and In-use Performance Tracking on 2000 and newer vehicles that support Mode 9.
• Modules Present: Displays module IDs and communication protocols for OBD II modules in the vehicle.
• Oil Reset: Resets the Engine Oil Life System after an oil change so it can calculate when the next oil change is required.
• BMS: Supports battery registration and reset, evaluates battery charge state, monitors close-circuit current, registers battery replacement, activates the rest state of the vehicle, and charges the battery via the diagnostic socket.
• EPB: Supports electric parking brake functions and parking brake pad relearn after replacement.
• SAS: Supports steering angle sensor calibration, permanently stores the current steering wheel position as the straight-ahead position in the steering angle sensor EEPROM, and automatically clears the steering angle sensor fault memory after successful calibration.
• DPF: Supports diesel particulate service, including forced regeneration, DPF component replacement teach-in, and DPF teach-in after replacing the engine control unit.
• Throttle: Supports throttle-related service functions.
• Adjust A/F: Supports Adjust A/F functions.
• Service Mileage & Intervals: Resets service mileage and service intervals.
• Brake Warning Light: Supports turning off the ECU brake warning light.
• OBD II Diagnostics: Provides quick access to the drive train systems of OBD II vehicles and supports the Power-train Control Module (PCM) and Transmission Control Module (TCM) when detected.
• OBD II Functions: Supports all OBD II protocols, all 10 test modes, and enhanced OBD II Mode 6.
• Print Diagnostic Reports: Supports printing diagnostic reports via PC connection.
• Multi-Language: Supports English, Traditional Chinese, French, German, Spanish, Portuguese, Dutch, Polish, Swedish, Korean, Japanese, Russian, Italian, Greek, and Simplified Chinese. A serial number is required to change the language.

4. Please note the following limitations:
Monitor Status: “N/A” indicates that the monitor being checked is not supported on that vehicle.
Component Test: The scan tool itself does not perform the EVAP leak test; it commands the vehicle’s on-board computer to start the test.
EPB Safety Requirements: The EPB control system may need to be deactivated before maintenance or diagnostic work and reactivated after the work is completed. Maintenance work should only be carried out when the vehicle is stationary and on level ground.
SAS Calibration Requirements: The front wheels and steering wheel must be set exactly to the straight-ahead position before calibration.
