3. Operating Instructions
3.1 General Navigation
The scanner features four main navigation buttons:
- OK Button: Confirms a selection or enters a menu.
- Return Button: Returns to the previous screen or cancels an operation.
- Up/Down Arrow Buttons: Navigates through menu options or data lists.
3.2 Diagnostic Functions
From the Main Menu, select 'Diagnostic' and press 'OK'. The scanner will automatically detect the vehicle's protocol. Once connected, you will see the Diagnostic Menu with various functions:
- Read Codes: Displays Diagnostic Trouble Codes (DTCs) stored in the vehicle's computer. This includes Stored Codes (current issues), Pending Codes (intermittent issues), and Permanent Codes.
- Erase Codes: Clears all stored DTCs and turns off the Check Engine Light (MIL). Ensure the underlying issue is resolved before erasing codes.
- Live Data: Displays real-time data parameters from the vehicle's sensors, such as engine RPM, vehicle speed, O2 sensor readings, and more. This is crucial for monitoring vehicle performance and diagnosing intermittent problems.
- Freeze Frame: Captures a snapshot of vehicle operating conditions at the moment a DTC was set. This data helps identify the conditions under which the fault occurred.
- Vehicle Info: Retrieves vehicle identification information, such as VIN (Vehicle Identification Number), CALID, and CVN.
- I/M Readiness: Checks the status of the vehicle's emission-related monitoring systems to determine if they have completed their diagnostic tests. This is essential for smog checks.
- Mode 6 (On-Board Monitor Test): Accesses the results of on-board diagnostic monitoring tests for specific monitored systems that are not continuously monitored. This can help identify misfires or other component issues.
- O2 Sensor Test: Retrieves O2 sensor monitoring test results from the vehicle's computer.
- Component Test (Mode 8): Allows initiation of a leak test for the vehicle's EVAP system.
