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 " 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.

As someone who frequently repairs cars, replacing the windshield requires careful handling of the ETC device. First, gently remove the device before taking out the old glass to prevent loss. After installing the new windshield, contact the ETC service center for reinstallation to ensure proper positioning and activation. Avoid DIY placement—even a slight misalignment can affect recognition or cause signal failure. It's recommended to use original adhesive or professional tools. Following these steps can save hassle; after replacement, test it on a short highway trip to confirm everything works. Regular , like cleaning the ETC interface to prevent dust buildup, helps avoid future issues.

Decades of driving experience have taught me to be cautious when replacing the windshield with an ETC device. Before removing the glass, detach the device and contact the ETC service point for reinstallation to avoid damaging it by forcing it off. Safety is the top priority throughout the process, and it's crucial not to delay to prevent disruptions to highway travel. After reinstallation, test it promptly to ensure proper functionality, and regularly clean the device to prevent dust buildup from affecting signal reception.

As a DIY enthusiast, I've tried replacing the windshield and reinstalling the ETC myself: When removing the device, gently scrape off the adhesive layer with a plastic card, then clean the residue with alcohol; After changing the windshield, reattach it to the original position, but ensure the surface is flat and use strong adhesive for fixation, finally reactivate via the App. Beginners should avoid attempting this casually, as significant position deviation may cause recognition failure; It's recommended to study ETC installation videos beforehand to improve skills—quick and cost-free.

For efficiency-driven individuals like me, handling windshield ETC replacement is all about speed. Book the service in advance and have the repair shop assist with device removal; reattach and activate it on the spot after the windshield is replaced—done seamlessly in under 30 minutes. Download the ETC app or note the customer service number beforehand to save time on reconnection. The entire process flows smoothly, ensuring zero delays in daily commutes.
