Operating Procedures

Navigating the Menu

Use the directional arrow buttons (Up, Down, Left, Right) on the scanner to navigate through menu options. Press the 'OK' button to confirm a selection or enter a submenu. The 'EXIT' button returns to the previous screen or menu.

Reading Fault Codes (DTC)

1. From the main menu, select 'Read Codes' or press the dedicated 'DTC' button.
2. The scanner will establish communication with the vehicle's Engine Control Unit (ECU) and display any stored Diagnostic Trouble Codes (DTCs).
3. Use the arrow buttons to scroll through the codes and their corresponding descriptions.

Clearing Fault Codes

1. After identifying and resolving the underlying issue that caused the fault code, select 'Clear Codes' from the menu.
2. Confirm the action when prompted. Clearing codes will turn off the Malfunction Indicator Lamp (MIL) on your dashboard.

Note: Clearing codes without addressing the root cause of the problem will likely result in the codes reappearing shortly.

I/M Readiness Status

1. Select 'I/M Readiness' from the main menu or press the dedicated 'I/M' button.
2. The scanner will display the status of various emission-related monitors (e.g., O2 Sensor, EVAP System). 'OK' indicates the monitor has completed its self-test, while 'INC' (Incomplete) means it has not yet run or completed.

This function is crucial for checking if your vehicle is ready for an emissions inspection.

Live Data Stream

1. Select 'Data Stream' from the main menu.
2. The scanner will display real-time sensor data from the vehicle's engine, such as engine RPM, vehicle speed, coolant temperature, and oxygen sensor readings.

Monitoring live data can help in diagnosing intermittent problems or verifying the correct operation of various sensors.

Viewing Vehicle Information

1. Select 'Vehicle Info' from the main menu.
2. The scanner will display information such as the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN).

Troubleshooting

• Scanner does not power on:
  • Ensure the OBD-II connector is securely plugged into the vehicle's port.
  • Verify the vehicle's ignition is in the ON position.
  • Check the vehicle's battery voltage. The scanner requires 9-16V to operate.
• Communication error with vehicle:
  • Ensure the vehicle is OBD-II compliant (most vehicles from 1996 onwards in the US, 2001 in Europe for petrol, 2004 for diesel).
  • Check for loose connections at the OBD-II port.
  • Try the scanner on another compatible vehicle to rule out scanner malfunction.
  • Ensure the vehicle's ECU is functioning correctly.
• Codes cannot be cleared:
  • The underlying fault that triggered the code must be repaired first. Codes will reappear if the issue persists.
  • Ensure the ignition is ON and the engine is OFF when attempting to clear codes.
• Screen is blank or frozen:
  • Disconnect the scanner from the vehicle and reconnect it.
  • If the issue persists, contact customer support.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the scanner's screen and body. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the device.
• Storage: Store the scanner in a cool, dry place, away from direct sunlight, extreme temperatures, and excessive humidity.
• Cable Care: Avoid bending or twisting the OBD-II cable excessively to prevent internal wire damage. Always grasp the connector when plugging or unplugging, not the cable itself.
