4. Operating Instructions

4.1 Connecting to a Vehicle

1. Locate the vehicle's OBDII port (usually under the dashboard).
2. Connect the main diagnostic cable to the XTOOL D5S tablet's DB15 port.

4.2 Vehicle Identification (Auto VIN Scan)

The D5S supports quick vehicle identification through several methods:

• Auto VIN Scan: The device attempts to automatically read the Vehicle Identification Number (VIN) from the vehicle's ECU. This shortens the navigation process by identifying the make, model, and year.
• Manual VIN Input: If Auto VIN fails, you can manually enter the 17-digit VIN.
• Automatic Selection: After selecting the vehicle manufacturer, the system may offer automatic model selection.
• Manual Selection: If VIN retrieval is not possible, you can manually select the vehicle details (make, model, year).

4.3 5 System Diagnostics

The D5S can diagnose the following main systems:

• Engine System (ECM): Read and clear engine fault codes, view live data.
• Transmission System (TCM): Diagnose transmission issues, view live data.
• Anti-lock Braking System (ABS): Read and clear ABS DTCs, turn off ABS warning lights, check wheel speed data.
• Supplemental Restraint System (SRS/Airbag): Diagnose airbag system faults, read and clear codes.
• Electronic Parking Brake (EPB): Diagnose EPB system, perform brake pad reset.

To perform a system diagnostic:

1. From the main menu, select "Diagnosis".
2. Choose the vehicle manufacturer and model (or use Auto VIN).
3. Select the desired system (e.g., "Engine System").
4. You can then choose to "Read Fault Codes", "Clear Fault Codes", "Read Live Data", or "Read ECU Information".

5.2 General Care

• Keep the device clean and free from dust and moisture.
• Avoid dropping the device or exposing it to extreme temperatures.
• Use only the provided charging cable and accessories.
• Store the device in a safe place when not in use.

6. Troubleshooting

6.1 Common Issues & Solutions

• Device not powering on: Ensure the battery is charged. If not, connect the charging cable and allow it to charge for a period before attempting to power on again.
• Connection issues with vehicle: Verify the diagnostic cable is securely connected to both the D5S and the vehicle's OBDII port. Ensure the vehicle's ignition is in the 'ON' position.
• Auto VIN Scan fails: If the device cannot automatically retrieve the VIN, it might be due to the car being too new/old for the VIN database, or the VIN is not a standard 17-digit format. In such cases, manually input the VIN or select the vehicle details. Contact XTOOL support with your car's VIN and device S/N for potential database updates.
• Software update failures: Check your Wi-Fi connection stability. Ensure there is sufficient storage space on the device.
• Specific function not working for a vehicle: Not all functions are universally compatible with all vehicle models. Always check the detailed car list on the XTOOL website (https://www.xtooltech.com/english/FunctionQuery.html) for compatibility before attempting advanced functions.

9. User Tips

• Check Vehicle Compatibility: Before purchasing or attempting specific functions, always verify your vehicle's compatibility with the XTOOL D5S on the official XTOOL website (https://www.xtooltech.com/english/FunctionQuery.html). This helps ensure the tool supports your car's make, model, and year for the desired diagnostic or service function.
• Keep Software Updated: Regularly update your D5S software via Wi-Fi. This ensures you have the latest vehicle coverage, bug fixes, and access to newly added features, maximizing the tool's effectiveness.
• Understand Auto VIN Limitations: While Auto VIN is convenient, be aware that it might not work for all vehicles, especially very new or very old models, or if the VIN is non-standard. In such cases, manual input or selection is necessary.
• Utilize Live Data Graphing: For complex diagnostics, use the 4-in-1 live data graphing feature. Visualizing multiple parameters simultaneously can help identify intermittent issues or correlations between different sensor readings more effectively than just viewing numerical data.
