Vehicle Connection

The scan tool must be connected to the vehicle's OBD-II port for proper communication. Follow these steps:

1. Turn on the tablet.
2. Connect the VCI with the vehicle via the main test cable and OBD adapter. Ensure the Wi-Fi connection is working correctly.
3. Switch on the vehicle ignition and tap on the Diagnostic application to start your diagnosis.

Important Notes for Vehicle Connection:

• The vehicle's DLC (Diagnostic Link Connector) is not always located under the dash; refer to the vehicle owner's manual for its exact location.
• Some older vehicles may not be compatible with the OBD II -16 adapter; ensure you are using the correct adapter for your vehicle.
• For models with DoIP protocol communication, ensure the device is connected to the vehicle by wire using the USB 3.0 to TYPE-B main cable to prevent data transmission issues during functions like ECU programming & coding.

3. Operation Instructions

Beginning Diagnostic Testing

Once the tablet is properly connected to the vehicle, you can start the diagnosis. The scan tool offers three methods for vehicle selection:

• AUTO SCAN: Automatically reads the vehicle's VIN code. Ensure the car and device are well connected.
• MANUAL INPUT: Allows manual entry of the car's VIN code. Ensure the 17 characters are correct for accurate results.
• SELECT VEHICLE BY AREA: Choose a car brand by selecting the appropriate region (e.g., Europe, America, Asia, China, Australia).

If your model is not recognized by AUTO SCAN:

1. Update all software and check if the APP is updated in [Settings].
2. Manually select the engine system in the Diagnosis menu to read ECU information and confirm if the VIN can be read.
3. Contact the XTOOL technical team with the VIN code to confirm model support.

Diagnosis Functions

The diagnostic application allows you to read ECU information, read and clear DTCs (Diagnostic Trouble Codes), check live data, and perform actuation tests across various vehicle control systems (Engine, Transmission, ABS, SRS, EPB, etc.).

Read ECU Information

This function retrieves ECU version information, including software and hardware versions, models, and production dates. This data is useful for maintenance records and ordering parts.

Read/Clear Trouble Code

This function allows you to read and clear current and historical trouble codes stored in the ECU memory. Ensure all issues are resolved before clearing codes to prevent them from reappearing.

Read Live Data

Real-time information from various sensors (PIDs) is displayed, such as oil pressure, temperature, and engine speed. This helps in identifying problems and narrowing down maintenance scope.

• Customization: Select and show multiple PIDs. Click "Display All" to view all PIDs and understand relationships between data parameters.
• Graphing: Combine different graphs into one chart for up to 8 real-time data PIDs.
• Data Recording: Record current data values as text. View recorded files in Reports > Data Replay.
• Pause: Pause the recording timeline for closer examination.

Actuation Test (Bi-Directional Control)

This function allows the device to send commands to vehicle control modules and receive information, enabling functional tests, actuator tests, and inspection tests. This helps in determining if actuating components are working correctly.

Special Functions (45+ Services)

The Scan Tool supports numerous special reset functions for scheduled services and maintenance. These functions often eliminate the need to reset codes after resolving common problems.

ABS Bleeding

Performs ABS bleeding to restore brake sensitivity when air is present in the ABS system. This is necessary after replacing the rear/front brake distributor pump, severe brake fluid shortage, or changing the brake fluid.

Oil Reset

Resets the engine oil life system after an oil change or when the service lamp is on. This ensures the system accurately calculates the next oil change interval.

EPB (Electronic Parking Brake) Reset

Resets the electronic parking brake system and brake pads. Required after brake pad replacement, when the brake pad indicator lamp is on, or if the servo motor is replaced.

SAS (Steering Angle Sensors) Reset

• Keep the unit away from strong magnetic fields.

Precautions for Diagnosis

• Ensure the voltage range on the car is +9V~+36V DC.
• When testing special functions, follow prompts and meet test conditions (e.g., engine water temperature, accelerator pedal position).
• For complex electronic control systems, if testing is impossible or data is abnormal, search for the vehicle's ECU and select the menu for the model on the ECU nameplate.
• If the vehicle type or electronic control system is not found, upgrade the diagnostic software or consult XTOOL technical service.
• Only use wiring harnesses provided by XTOOL to prevent damage to the vehicle or scan tool.
• Do not shut down the scan tool directly during a Diagnostics function; cancel the task before returning to the main interface.

Common Issues and Tips
