- Wi-Fi: Compatible with both Android and iOS devices.
Important Note for iOS Bluetooth 4.0 Users:
When using an iOS device with the Bluetooth 4.0 version, do NOT connect the device directly through your phone's Bluetooth settings. Instead, open the diagnostic application and connect to the iCar Pro's Bluetooth from within the app itself.
2.3 Installation Steps
- Download the App: Download a compatible OBD2 application such as "Auto Doctor" from your device's App Store (iOS) or Google Play Store (Android). The iCar Pro works with most popular OBD2 apps.
- Locate OBD-II Port: Turn on your car's ignition (engine can be off or running). Locate your vehicle's OBD-II diagnostic port, usually found under the dashboard on the driver's side.
- Plug in the Adapter: Firmly plug the Vgate iCar Pro adapter into the OBD-II port. The device's indicator lights should illuminate.
- Connect via App:
- For Bluetooth (Android): Go to your phone's Bluetooth settings, pair with "Vgate" or "iCar Pro". Then open the app and select the device.
- For Bluetooth (iOS): Open the diagnostic app directly. Do NOT pair via phone settings. Within the app, navigate to connectivity settings and select the iCar Pro Bluetooth device.
- For Wi-Fi: Go to your phone's Wi-Fi settings, connect to the "Vgate" or "iCar Pro" Wi-Fi network. Then open the app and select the device.
- Refresh and Connect: Within the app, refresh the connection or initiate a scan to establish communication with your vehicle.

3.2 Automatic Wake-up and Sleep
The Vgate iCar Pro features an intelligent automatic wake-up and sleep function to conserve power and enhance convenience. This feature is not supported for electric vehicles.
- When the car's ignition is turned on, the iCar Pro will automatically start.
- Approximately 30 minutes after the car stalls (engine is turned off), the iCar Pro will automatically enter sleep mode.
4. Maintenance
To ensure the longevity and optimal performance of your Vgate iCar Pro, follow these maintenance guidelines:
- Keep the device clean and free from dust and moisture. Use a soft, dry cloth for cleaning.
- Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods.
- Store the device in a cool, dry place when not in use.
- Do not attempt to disassemble or repair the device yourself, as this will void the warranty.
5. Troubleshooting
If you encounter issues with your Vgate iCar Pro, consider the following troubleshooting steps:
- Device Not Powering On: Ensure the device is firmly plugged into the OBD-II port and the vehicle's ignition is on. Check for any blown fuses in your vehicle's fuse box related to the OBD-II port.
- Connection Issues (Bluetooth/Wi-Fi):
- For Android Bluetooth: Ensure Bluetooth is enabled on your phone and the iCar Pro is paired. If already paired, try unpairing and re-pairing.
- For iOS Bluetooth: Remember to connect within the app and not directly through your iPhone's Bluetooth settings. If you previously paired it via phone settings, forget the device and try connecting via the app again.
- For Wi-Fi: Ensure your phone is connected to the iCar Pro's Wi-Fi network. Check that no other Wi-Fi networks are interfering.
- Restart both your phone and the vehicle.
- App Not Displaying Data:
- Ensure the app is up-to-date.
- Verify that the app's settings correctly identify and connect to the iCar Pro device.
- Try a different compatible OBD2 app to rule out app-specific issues.
- "Check Engine" Light Not Clearing: Some fault codes require specific driving cycles or multiple clear attempts. Ensure the underlying issue causing the code has been resolved before attempting to clear it.
