- Erasing Codes: Clears DTCs from the vehicle's ECU, turning off the Malfunction Indicator Lamp (MIL).
- Live Data Stream: Shows real-time data parameters from the vehicle's sensors and components in text or graphical format. You can select up to two parameters for a merged graph display for intuitive analysis.
- I/M Readiness: Indicates whether the various emissions-related systems are operating correctly and are ready for inspection and maintenance testing.
- Freeze Frame: Captures a snapshot of critical vehicle operating conditions at the moment an emission-related fault occurs.
- On-Board Monitor Test: Accesses the results of on-board diagnostic monitoring tests for specific components/systems.
- O2 Sensor Test: Retrieves and displays O2 sensor monitor test results for the most recently performed tests.
- EVAP Monitor Test: Retrieves and displays test results for emission-related powertrain components and systems, specifically for the Evaporative Emission Control System.
- Read Vehicle Information: Displays vehicle identification information such as VIN (Vehicle Identification Number), CID (Calibration ID), and CVN (Calibration Verification Number).
- Component Test: Allows certain vehicle components to be actuated by commands sent from the scanner to test their operability.

4.2 25+ Maintenance Services
The NT650 Pro offers a wide array of maintenance and reset functions. Please note that service functions are primarily designed for imported vehicles, and compatibility with domestic vehicles may be limited. Always consult the manufacturer for specific vehicle compatibility before performing these services.
Figure 6: 25+ Maintenance Functions
- Oil Service Reset: Resets the service lamps on the instrument cluster after an oil change.
- EPB (Electronic Parking Brake): Performs service and maintenance of brake systems, including deactivation/activation of the brake control system, bleeding brake fluid, opening/closing brake pads, and setting brakes after disc or pad replacement.
- BRT (Battery Replacement): Validates new battery, clears faults from the dashboard, and displays battery information.
- DPF (Diesel Particulate Filter Regeneration): Initiates DPF cleaning to clear blockages by burning particulates. The DPF light goes off automatically upon completion.
- TBA/TPS (Throttle Body Alignment): Learns the full open and full closed positions of the throttle body through various states.
- SAS (Steering Angle Sensor Calibration): Calibrates the Steering Angle Sensor.
- TPMS (Tire Pressure Monitoring System Programming): Checks tire sensor IDs from the vehicle ECU and performs TPMS programming and reset after tire/sensor replacement or rotation.
- Gear Learning: Performs crankshaft position sensor adaptive learning.
- CVT: Resets compensation code and initializes the ECT after solenoid valve or valve body assembly replacement.
- Injector Coding: Resets and matches data after injector replacement.
- A/F Adjust: Adjusts fuel supply to maintain energy balance in the combustion process.
- ABS Bleeding: Performs ABS brake bleeding to achieve a firm brake pad after air exhaustion.

4.3 ABS/SRS Code Reader & Bidirectional Control Test
The NT650 Pro is capable of diagnosing and performing bidirectional control tests on ABS (Anti-lock Braking System) and SRS (Supplemental Restraint System) systems.
- For ABS System: Diagnoses ABS problems by reading ECU information, live data, and fault codes. It can clear ABS system fault codes and turn off the trouble indicator after repairs.
- For SRS System: Detects electronic parameters of the SRS system (impact sensors, control module, airbags) to check its health status. It can read ECU information, live data, and fault codes, and turn off the trouble indicator after repairs.
- Bi-directional Active Test: This advanced feature allows you to command components to pinpoint faults. For example, you can perform an ABS manual control test, ABS motor test, or other actuator tests. This helps to temporarily activate or control components, enabling more accurate problem identification.
