4.2 Diagnostic Menu Functions

After connecting the device and it links to the vehicle, the main menu will appear. Use the arrow keys to navigate and OK to select.

1. Read Codes: Displays current, pending, and permanent Diagnostic Trouble Codes (DTCs).
2. Erase Codes: Clears all stored DTCs from the vehicle's computer. This will also turn off the Check Engine Light (MIL).
3. View Freeze Frame: Shows a snapshot of sensor data at the moment a fault code was triggered.
4. I/M Readiness: Checks the status of the vehicle's emission-related monitoring systems to determine if the vehicle is ready for an emission test.
5. Vehicle Information: Retrieves vehicle identification number (VIN), calibration ID (CALID), and calibration verification number (CVN).
6. Live PCM Data: Displays real-time sensor data from the vehicle's Powertrain Control Module (PCM).
7. Realtime Curve: Presents live sensor data in a graphical format for easier analysis.
8. O2 Sensor Test: Retrieves O2 sensor monitoring test results.
9. On-Board Mon. Test: Accesses results for on-board diagnostic monitoring tests of specific components/systems.
10. Component Test: Allows for testing of specific vehicle components.

4.3 Battery Test Functions

Press the BAT hot-key to directly access battery functions:

1. Battery Measurement: Displays the current battery voltage.
2. Battery Monitoring: Shows a real-time curve of the car battery voltage change.
3. Battery Life: Assesses the battery's overall health and life status. Follow on-screen prompts, which may include turning the engine off and on.

4.4 DTC Lookup

Use the DTC Lib (DTC Lookup) function to search for fault code definitions directly on the device. Enter the fault code to query its definition.

4.5 System Setup

Access the 'Setting' menu to configure device preferences:

• Language: Select from 13 built-in languages (German, Dutch, English, Spanish, French, Italian, Finnish, Portuguese, Polish, Chinese, Korean, Russian, Japanese).

5. Maintenance

• Keep the device clean and dry. Use a soft, damp cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
• Store the device in a safe place, away from extreme temperatures, direct sunlight, and excessive moisture.
• Avoid dropping the device or subjecting it to strong impacts.
• Regularly check the OBDII cable for any signs of damage.

6. Troubleshooting

6.1 Device Does Not Power On

• Ensure the OBDII connector is securely plugged into the vehicle's DLC.
• Verify the vehicle's ignition is in the ON position.
• Check the vehicle's battery for sufficient charge.

6.2 Communication Error

• Confirm the vehicle supports OBDII/EOBD protocols.
• Check for any loose connections between the scanner and the vehicle.
• Turn off the ignition, wait a few seconds, and then turn it back on before attempting to connect again.
• If the issue persists, try the scanner on a different compatible vehicle to rule out a vehicle-specific problem.

6.3 Cannot Clear Codes

• Ensure the ignition is in the ON position (engine off).
• Some fault codes may be 'hard codes' that reappear immediately if the underlying issue is not resolved. Clearing codes only turns off the warning light; it does not fix the problem.
• If codes cannot be cleared, there might be a persistent fault that requires professional attention.

6.4 Incorrect Language Display

• Navigate to the 'Setting' menu and select 'Language' to choose your preferred language.

8. User Tips

• Always ensure your vehicle's ignition is in the ON position when performing diagnostic tests.
• For battery life assessment, follow the on-screen prompts carefully, which may require turning the engine off and on.
• When clearing codes, remember that this only resets the warning light. The underlying issue causing the code must be addressed to prevent it from reappearing.
• Utilize the 'Live PCM Data' and 'Realtime Curve' functions to observe sensor readings in real-time, which can help pinpoint intermittent issues.
