2. Getting Started: Setup
Before using your ANCEL AD410 or AD310 scanner, ensure your vehicle's ignition is in the ON position (engine off or running, depending on the test).
- Locate the OBDII Port: The 16-pin Data Link Connector (DLC) is usually located under the dashboard on the driver's side. Refer to your vehicle's service manual if you cannot locate it.
- Connect the Scanner: Plug the scanner's OBDII cable into the vehicle's DLC. The scanner will power on automatically as it draws power directly from the vehicle's OBDII port.
- Initial Boot-up: The scanner will display the main menu or a boot-up screen.

3. Operating Instructions
3.1. Basic Navigation
Both the AD410 and AD310 feature intuitive button layouts:
- ENTER/OK Button: Confirms selections or enters menus.
- EXIT/Back Button: Returns to the previous screen or cancels an operation.
- Up/Down Arrows: Navigate through menu options.
- I/M Button (AD410) / I/M Readiness (AD310 menu): Directly accesses the I/M Readiness function.
3.2. Reading and Clearing Diagnostic Trouble Codes (DTCs)
This function allows you to retrieve and clear engine fault codes that trigger the Check Engine Light (MIL).
- Read Codes:
- From the main menu, select "Read Codes" (AD310) or "OBDII" then "Read Codes" (AD410).
- The scanner will display any stored, pending, or permanent DTCs along with their definitions.
- Clear Codes:
- After reading codes, select "Erase Codes" from the menu.
- Confirm the action when prompted. This will turn off the Check Engine Light (MIL) and clear all diagnostic data.
- Note: Clearing codes does not fix the underlying problem. The MIL will illuminate again if the fault persists.

3.3. I/M Readiness Test
The I/M Readiness function checks if the various emissions-related systems on the vehicle are operating correctly and are ready for inspection and maintenance testing (smog check).
- Press the dedicated I/M button (AD410) or select "I/M Readiness" from the menu (AD310).
- The scanner will display the status of various monitors (e.g., O2 Sensor, EVAP, Catalyst). A "Ready" or "OK" status indicates the monitor has completed its self-test.
- Note: Some monitors may require specific driving conditions to complete their tests.

3.4. Enhanced Diagnostic Functions (AD410)
The AD410 offers advanced diagnostic capabilities beyond basic code reading:
- O2 Sensor Test: Monitors and adjusts the air/fuel mixture. This test helps identify issues related to fuel efficiency and vehicle emissions.
- EVAP (Evaporative Control System) Test: Initiates a leak test of the vehicle's EVAP system to monitor the integrity of the fuel tank system and prevent gasoline vapor escape.
- Live Data Stream: Displays real-time sensor data from the vehicle's ECU, such as engine RPM, vehicle speed, oxygen sensor readings, and more. This is useful for diagnosing intermittent problems.
- View Freeze Frame: Captures a snapshot of critical vehicle operating conditions at the moment a DTC was set. This data can help determine the cause of the fault.
- DTC Lookup: Allows you to manually enter a DTC and view its definition without connecting to a vehicle.
- Vehicle Information: Retrieves the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN) of the vehicle.

4. Maintenance
To ensure the longevity and proper functioning of your ANCEL AD410 and AD310 scanners, follow these maintenance guidelines:
- Cleaning: Use a soft, damp cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
- Storage: Store the scanner in a clean, dry environment, away from extreme temperatures, direct sunlight, and excessive dust.
- Cable Care: Avoid bending or twisting the OBDII cable excessively. Always grasp the connector when plugging or unplugging it from the vehicle's DLC.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | Loose connection; Vehicle's OBDII port not supplying power; Vehicle battery low. | Ensure the OBDII cable is securely connected. Check vehicle's ignition is ON. Verify vehicle battery voltage. Try on another vehicle if possible. |
| "Link Error" or "Communication Error" message. | Incorrect protocol; Faulty connection; Vehicle's ECU not responding. | Verify vehicle is OBDII compliant (1996 or newer in U.S.). Check cable connection. Turn ignition OFF, wait 10 seconds, then ON again. Try on another vehicle. |
| Cannot clear codes. | Ignition not ON; Underlying fault still present. | Ensure ignition is ON (engine off). Address the root cause of the DTC before attempting to clear. |
