4. Operating Instructions

Navigate the scanner using the directional buttons (UP, DOWN, LEFT, RIGHT) and the ENTER/EXIT buttons. The main menu provides access to various diagnostic functions.

4.1 Main Menu Functions

• Dianossis (Diagnosis): Accesses the primary diagnostic functions.
• Battery: Displays real-time battery voltage.
• DTC Lib (DTC Library): Allows lookup of Diagnostic Trouble Codes.
• Setting: Configures device settings, including language.

4.2 Diagnostic Functions

From the "Dianossis" menu, you can perform the following operations:

1. Read Codes:

   Select "Read Codes" to retrieve current, pending, and permanent Diagnostic Trouble Codes (DTCs) from the vehicle's engine control unit (ECU). The codes will be displayed on the screen along with a brief description if available in the internal database.

2. Erase Codes:

   After addressing the underlying issue that triggered the DTCs, select "Erase Codes" to clear the codes from the vehicle's ECU and turn off the Check Engine Light (MIL). Confirm the action when prompted. Note: Clearing codes without fixing the underlying problem will likely result in the codes reappearing.
3. View Freeze Frame:

   When an emission-related fault occurs, the vehicle's computer records certain vehicle operating conditions at the time of the fault. This data is called Freeze Frame Data. Select "View Freeze Frame" to review this snapshot of data, which can help in diagnosing the cause of the fault.

4. I/M Readiness:

   I/M Readiness (Inspection/Maintenance Readiness) indicates whether the various emission-related systems on the vehicle are operating correctly and have completed their self-tests. This function is useful for checking if a vehicle is ready for an emissions test. A dedicated "I/M" button is available for quick access.

5. Retrieve Vehicle Info:

   This function allows you to retrieve the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN) from the vehicle's ECU.

6. Live Data:

   View real-time operational data from the vehicle's sensors and components. This includes engine RPM, vehicle speed, coolant temperature, oxygen sensor readings, and more. This data can be viewed as a list or as a real-time curve (graph).

7. Voltage Test:

   Perform a real-time voltage test of the vehicle's battery. This helps in assessing the battery's health.

8. O2 Sensor Test:

   Retrieves O2 sensor monitoring test results for the most recently completed tests from the vehicle's on-board computer.

9. EVAP Test:

   Initiates a test of the Evaporative Emission Control System (EVAP) for leaks.
