To perform a full system diagnosis:

1. Connect the Bluetooth dongle to the vehicle's OBD2 port.
2. On the tablet, select "Diagnose" from the main menu.
3. Choose "Auto VIN" for automatic vehicle identification or manually select the vehicle type.
4. Select "Health Report" or "System Scan" to initiate a comprehensive scan of all available systems.
5. Review the displayed fault codes (DTCs) and system statuses.

3.2 Live Data Stream

Monitor real-time data from various sensors and components in graphical or text format. This feature is crucial for identifying intermittent issues and verifying component operation.

To view live data:

1. After a system scan, select the desired module (e.g., Engine Control Module).
2. Choose "Live Data" or "Data Stream."
3. Select the parameters you wish to monitor. The device can display up to 4 data streams simultaneously.

3.3 Bi-directional Control (Active Testing)

This function allows the diagnostic tool to send commands directly to vehicle components to test their functionality. This helps in quickly pinpointing faulty parts without disassembling the vehicle.

Figure 3.3: Examples of bi-directional control, such as activating lights or fuel pump.

Common active tests include:

• Coolant pump activation
• Window up/down control
• Lighting control
• Fuel pump on/off
• Injector tests

To perform active tests, navigate to Diagnosis > Vehicle Models > System > Active Test. Note that available functions vary by vehicle model and year.

3.4 ECU Coding

ECU coding allows for customization of vehicle settings, activation of hidden features, or deactivation of unwanted functions. It is also used to program adaptive data for specific components after repairs or replacements.

Examples of ECU coding applications:

• Changing interior lighting color
• Activating/deactivating auto-hold function
• Customizing dashboard display
• Disabling automatic start/stop

Note: ECU coding functions vary significantly by vehicle make, model, and year. Always ensure you understand the implications before making changes.
