How to Activate ETC for the Second Time?

ETC second activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth is on". If it shows "Tag invalid" when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth function. Turn on your phone's Bluetooth, open the corresponding mobile APP (usually there is a download QR code on the electronic tag), and enter the device activation interface. Click on device connection and wait patiently for the "Connection successful" prompt. After successful connection, upload a photo of the vehicle's front to complete activation. ETC installation positions: For small vehicles like cars and minivans, the ETC card and OBU device should be installed on the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is on the lower middle part.

When I reinstalled the ETC for my new car, I figured out the process and found the key lies in the Bluetooth pairing step. First, park the car in an open area and turn on the OBU device (activation methods vary by device—some require double-tapping the card, others need a long press on the side button). A flashing green light indicates pairing mode. Then, open the official ETC app for your province on your phone, log in, and click 'Reactivate' in the device management section. The system will automatically search for the device. After Bluetooth pairing, you’ll need to take a clear photo of the entire front windshield, showing both the license plate and the installed ETC device. Upload it and wait about two minutes for system approval. A tip: avoid blocking the internal solar panel with the device placement, or activation will repeatedly fail—I learned this the hard way and had to reinstall mine.

Both of our family cars have experienced ETC deactivation requiring secondary activation, and the simplest solution we've found is to operate via the mobile app. First, ensure you can still log into the account of the app used during device installation. While interfaces vary slightly across provinces, most apps have options like 'Device Activation' or 'Tag Reactivation'. The key is to enable both OBU Bluetooth and phone Bluetooth simultaneously: long-press the device button until the green light flashes, then immediately tap 'Search for Device' in the app. After successful connection, don't rush to exit—follow the prompts to take three photos: a full windshield view, a close-up of the ETC device, and a front view of the vehicle. You'll receive an activation success SMS within ten minutes after uploading. A handy tip: high summer temperatures in the car can affect Bluetooth connectivity, so it's best to perform this operation in the early morning or evening.

Last month, I just completed the secondary activation of my ETC, and found that the core process boils down to three steps. First, turn on the device's Bluetooth (usually by pressing the side button until the light changes from red to green). Second, enable Bluetooth on your phone and run the ETC app to pair with the device. Third, follow the prompts to take and upload photos of your vehicle. The most common issue encountered during actual operation is Bluetooth connection failure. If your phone can't detect the device, try turning off and disconnecting the car's power for five minutes before restarting. Special note: some car models have windshields with metal coatings that may interfere with signals, requiring professional activation at service points. During my activation, I noticed the app requires location permissions, so I recommend operating outdoors for more stable performance.
