Quick diagnosis screen with various menu options and data streams — Figure 7.2: Quick Diagnosis with Rich Information.

7.2. Read Codes

This function allows you to retrieve Diagnostic Trouble Codes (DTCs) from the vehicle's computer. These codes indicate specific issues detected by the vehicle's self-diagnostic system.

From the Diagnostic Menu, select "1) Read Codes".
The scanner will display any stored DTCs.

7.3. Erase Codes

After addressing the underlying issue, you can use this function to clear the DTCs and turn off the Check Engine Light (MIL).

From the Diagnostic Menu, select "2) Erase Codes".
Confirm your choice when prompted.
The codes will be cleared, and the MIL should turn off.

7.4. View Freeze Frame

When an emission-related fault occurs, the vehicle's computer stores certain vehicle operating conditions (Freeze Frame Data). This data helps you understand the conditions at the time of the fault.

From the Diagnostic Menu, select "3) View Freeze Frame".
The scanner will display the stored freeze frame data.

7.5. I/M Readiness Test

I/M Readiness checks if your car's emission control systems are ready for inspection. This is crucial for annual smog tests.

From the Diagnostic Menu, select "4) I/M Readiness".
The scanner will display the status of various emission monitors (e.g., MIL Status, Misfire Monitor, Fuel System Mon, Comp. Component).

I/M Readiness Test screen showing monitor status — Figure 7.3: I/M Readiness Test results.

7.6. Live Data Stream

View real-time data from the vehicle's sensors and components with the engine on. This helps in diagnosing intermittent problems and monitoring vehicle performance.

From the Diagnostic Menu, select "6) Data Stream".
The scanner will display various parameters like FUELSYS2, LOAD_PCT(%), ETC(°F), Fuel System Mon, Comp. Component, etc.

Live Data Display screen showing real-time engine parameters — Figure 7.4: Live Data Display.

7.7. Real-time Chart

Visualize live data parameters in a graphical format for easier analysis of trends and fluctuations.

From the Diagnostic Menu, select "7) RealTime Curve".
Choose the parameters you wish to graph (e.g., Car Speed, Calculate Load Value, Engine Coolant Temp, Engine RPM).

7.8. DTC Lookup

This feature provides definitions for Diagnostic Trouble Codes, helping you understand what's wrong with your car in plain language.

Press the dedicated "DTC" button or select "DTC Lookup" from the menu.
Enter the DTC code using the arrow buttons.
The scanner will display the definition of the code.

Select "Unit of Measure" to switch between English (Imperial) and Metric units.
Select "Contrast" to adjust the screen brightness.

8. Maintenance and Care

Cleaning: Use a soft, damp cloth with mild detergent to clean the scanner's exterior. Do not use abrasive cleaners or solvents.
Storage: Store the device in a dry, clean environment away from extreme temperatures, humidity, and direct sunlight.
Cable Care: Avoid bending or twisting the OBDII cable excessively. Store it neatly to prevent damage.
No User-Serviceable Parts: Do not attempt to open or repair the scanner yourself. This will void the warranty.

9. Troubleshooting

Problem	Possible Cause	Solution
Scanner does not power on	Loose connection, vehicle ignition off, blown fuse in vehicle's OBDII circuit.	Check OBDII cable connection. Ensure ignition is ON. Check vehicle's fuse box for a blown fuse related to the OBDII port.
"LINK ERROR" message	Vehicle not OBDII compliant, faulty connection, communication protocol issue.	Verify vehicle is OBDII compliant (1996 US, 2001 EU, 2008 Asian). Re-connect the scanner. Try on another compliant vehicle if possible.
Screen is dim or unreadable	Contrast setting is too low.	Adjust the display contrast in the System Setup menu.
Cannot clear codes	Underlying fault still present, ignition not in ON position.	Ensure the vehicle's ignition is ON (engine off). The fault must be repaired before codes can be permanently cleared.

10. User Tips

Always turn off the ignition before connecting or disconnecting the scanner to prevent potential damage to the vehicle's ECU or the scanner.
Record DTCs before clearing them. This provides a reference if the issue recurs.
Use the I/M Readiness function before an emissions test to ensure all monitors are complete and avoid failing the test.
Monitor Live Data while driving (if safe and with a passenger assisting) to observe sensor readings under various operating conditions, which can help pinpoint intermittent issues.
Keep the software updated if updates become available (check manufacturer's website).

11. Warranty and Support

For warranty information, technical support, or service inquiries, please refer to the contact information provided by your retailer or the manufacturer's official website. Keep your purchase receipt as proof of purchase.
