6.2. Initial Setup
- Before First Use: Remove all protective films from the device.
- App Installation: Download a compatible OBD II app (e.g., Torque for Android, Car Scanner for iOS). You can scan the QR code provided in the manual or product packaging to find the official app.
- Device Connection: The Vgate iCar Pro connects to your vehicle's OBDII port, typically located under the dashboard.
6.3. Operation Method (for Current Tester)
- Turn off the ignition switch of the vehicle.
- Remove the blade fuse attached to the tester from the jack, and then remove the vehicle's fuse from the circuit to be tested. Insert the tester's safety fuse into the wire socket. This ensures the correct level of circuit protection. (Fuses with the tester blade rating 20A/48V, standard type).
- Select the appropriate plug (medium or small) according to the size of the blade fuse. If small, the small tail can be connected to the medium plug, then plug into the vehicle fuse socket.
- Turn on the ignition switch of the vehicle if necessary to energize the circuit. Then turn on the tester (press the power button) and measure the current data.
- The display will show the measured current data of the circuit.
- When the display shows "DC", the circuit under test is a positive current. When "-DC" is displayed, the circuit under test is a negative current.
- After measurement, turn off the tester (press the power button again).
6.4. Connecting to the App (Bluetooth/WIFI)
- Plug the Vgate iCar Pro into your vehicle's OBDII port.
- Turn on your vehicle's ignition (do not start the engine).
- Enable Bluetooth or WIFI on your smartphone/tablet.
- Open your chosen OBD II app.
- In the app's settings, select the appropriate connection type (Bluetooth or WIFI) and pair with the Vgate iCar Pro device. Look for device names like "Android-Vlink" or similar.
- Once connected, the app will display real-time data from your vehicle.
