- F1 Button: Context-sensitive function button (refer to on-screen prompts).
4.2 Full OBD2 Functions
The AD710 supports all 10 modes of OBDII diagnostics:
- Read Codes: Retrieves generic (P0, P2, P3, and U0) and manufacturer specific (P1, P3, and U1) codes.
- Erase Codes: Clears Diagnostic Trouble Codes (DTCs) and resets the Check Engine Light (MIL).
- I/M Readiness: Checks the readiness of the emission monitoring systems.
- Data Stream: Displays live data stream in text or graph format.
- O2 Sensor Test: Retrieves O2 sensor monitor test results.
- On-Board Monitoring: Retrieves test results for emission-related powertrain components and systems.
- EVAP System Test: Initiates a leak test for the vehicle's EVAP system.
- Vehicle Information: Retrieves the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN).
- Freeze Frame: Displays a snapshot of operating conditions at the time of an emission-related fault.

4.3 System Diagnostics (ENGINE/ABS/SRS)
The AD710 provides in-depth diagnostics for critical vehicle systems:
- ENGINE Diagnosis: Offers advanced diagnostics, including testing of O2 sensors and EVAP systems. Perform a leak test on your vehicle's EVAP system and monitor the fuel tank's integrity. The O2 sensor test helps fine-tune the air/fuel mixture, improving fuel efficiency and reducing emissions.
- ABS Diagnosis: Quickly identify and resolve ABS-related issues, including sensor faults (such as wheel speed sensors), wiring problems (faulty circuits or connectors within the ABS system), or ABS pump failures (malfunctions in the ECU controlling the ABS). Ensure proper system operation, restore optimal braking performance, and clear any warning lights.
- SRS Diagnosis: Quickly detect issues within the Supplemental Restraint System, such as airbag ECU faults, airbag sensor failures, airbag system plug disconnections or poor contacts, and seat belt sensor failures or system errors. This ensures the SRS is working properly. After repair, reset the system to clear the warning light and restore full safety performance. Note: It cannot reset Airbag crash or transmission codes.

4.4 12V Complete Battery Test
The AD710 supports testing of 6V and 12V lead-acid batteries with Cold Cranking Amps (CCA) ranging from 100 to 2000. This function provides accurate battery health analysis.
- Battery Test: Checks the overall health and charge level of the battery.
- Cranking Test: Analyzes the starting system, including starter motor and ignition switch.
- Charging Test: Evaluates the vehicle's charging system, including the alternator and regulator.
- Review Data: Allows you to view previously recorded test results.

4.5 Reset Services (Lifetime Free)
The AD710 offers two crucial reset functions:
4.5.1 ABS Bleeding
This function exhausts air from the ABS pump to ensure the normal operation of the ABS system.
Notes:
- The vehicle's electronic parking brake (or hand brake) must be released.
- For some specific models (e.g., 2020 Audi Q3), the vehicle hood must be opened.
Procedure:
- Step 1: First Flush Cycle.
- Step 2: Front Bleeding.
- Step 3: Second Flush Cycle.
- Step 4: Rear Bleeding.
4.5.2 EPB (Electronic Parking Brake) Replace Brake Pads
After replacing the brake pads, the service life of the new brake pads needs to be reset.
Notes:
- The vehicle must have an electronic handbrake to enable the EPB function.
- The vehicle must be parked in a stable area, and the battery must be sufficiently charged.
- For some specific models (e.g., 2020 Audi Q3), the vehicle hood must be opened.

4.6 DTC Lookup
The DTC Lookup function allows you to view the definition of a fault code directly on the device screen, eliminating the need to search online. It shows the code and its meaning.

4.7 DLC PIN Test
This feature detects the voltage of the 16-pin DLC (Data Link Connector) diagnosis, helping to identify potential wiring or power issues with the OBDII port.
The test displays voltage readings for various pins, including:
- Chassis ground
- Signal ground
- SAEJ1850 bus+
- SAEJ1850 bus-
- ISO 15765-4 (CAN high)
- ISO9141 (K-line)
- ISO9141 (L-line)
- Battery Power (+12V)
- ISO 15765-4 (CAN LOW)
