Many users encounter frustrating issues when trying to connect their Chinese OBD2 scanners to their Android phones or car radios. If you’re facing a similar problem where your OBD2 dongle refuses to pair, you’re not alone. This article explores common reasons why your “chinese obd2 scanner won’t connect to phone” and offers potential solutions to get you back on track.
One common scenario involves users attempting to pair Bluetooth OBD2 dongles with Android car radios, only to find the connection failing repeatedly. Take the example of a user with an Android 10 car radio struggling to connect KONNWEI KW902 and vgate iCar Pro OBD2 Bluetooth 4.0 (BLE) dongles. Despite these dongles working perfectly with phones, tablets, and laptops, the car radio stubbornly refuses to pair.
The user meticulously navigated the hidden Bluetooth settings on their Android car radio, even attempting to manually set pairing codes and disable auto-connect features. However, the system consistently rejects the pairing code, displaying “code is not correct” messages, even when entering the correct code or trying default codes like “0000” or “1234”. Attempts to use a USB keyboard to bypass potential onscreen keyboard issues also proved futile.
This situation raises questions about the compatibility or configuration of these Android car radios with certain OBD2 scanners. It’s possible that specific Bluetooth protocols or security settings on these devices are causing interference. While the user’s experience is with a car radio, similar connection problems can occur when trying to pair these scanners directly with Android phones.
If you are experiencing “chinese obd2 scanner won’t connect to phone” issues, consider these troubleshooting steps:
- Verify Bluetooth Compatibility: Ensure your OBD2 scanner and Android device both support compatible Bluetooth versions. Some older scanners might use older Bluetooth protocols that are not fully compatible with newer Android versions.
- Check OBD2 Scanner Bluetooth Functionality: Test your OBD2 scanner with a different phone or device to confirm the scanner itself is broadcasting a Bluetooth signal and is pairable.
- Android Bluetooth Settings: Double-check your Android device’s Bluetooth settings. Ensure Bluetooth is enabled, and try forgetting any previously paired Bluetooth devices that might be causing conflicts.
- OBD2 App Compatibility: Confirm that the OBD2 app you are using is compatible with your specific OBD2 scanner model and Android version. Some apps may have limitations or require specific scanner types.
- Scanner Reset: Some OBD2 scanners have a reset button or procedure. Consult your scanner’s manual to see if a reset can resolve pairing issues.
- Firmware Updates: Check if firmware updates are available for your OBD2 scanner or Android car radio. Manufacturers sometimes release updates to address compatibility issues.
While the exact cause of connection failures can vary, systematically checking these points can help you pinpoint the problem and potentially find a solution to get your “chinese obd2 scanner won’t connect to phone”. If the problem persists, consulting online forums specific to your car radio or OBD2 scanner model might provide further insights and user-specific solutions.
