What to do with ETC when replacing the front windshield?
2 Answers
After replacing the front windshield, the ETC needs to be reactivated at the ETC service office. ETC activation method: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth is on". If "Tag invalid" is displayed when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. You can also directly press the button on the top of the electronic tag to enable Bluetooth. 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 front of the vehicle to complete activation. How ETC works: Through dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, using computer networking technology for back-end settlement processing with the bank, the vehicle can pass through highway or bridge toll stations without stopping to pay the highway or bridge toll.
That time I just had my windshield replaced, I was also worried about what to do with the ETC. I remember before replacing the glass, I used a small card to gently pry open the ETC device, being careful not to tear the adhesive pad. After moving the device, I quickly opened the ETC service app to schedule a reinstallation—they came the next day to stick it back in place and had it activated in no time. Don’t forget to take photos of the original position during the process to avoid issues on the highway. It’s also a good idea to regularly check the ETC status, like whether it’s loose, to prevent future hassles. The whole process turned out surprisingly simple—windshield replacement plus ETC reinstallation was done in half a day. Just test the signal while driving to make sure it works fine.
