What to do if the ETC falls off after activation?

If the ETC falls off after activation, it needs to be reactivated. The steps are: 1. Insert and remove the card twice in succession until the electronic tag displays that Bluetooth is on; 2. Insert and remove the card twice without attaching the electronic tag. If it shows that the tag is invalid, this is normal; 3. Open the corresponding ETC card app on your phone, enter the device activation interface, select the device model that needs to be connected, and wait for the connection to succeed; 4. Follow the prompts to verify and upload a photo of the vehicle's front. ETC is a solution for busy highway toll collection, enabling automatic tolling on highways or bridges. It uses dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station.
I helped my cousin deal with this situation a couple of days ago. If your ETC device falls off, don't just press it back on directly. First, check if the anti-tamper switch on the back of the device has popped out. If that small button is raised, it means the device has automatically locked and needs to be reactivated. Use a clean towel to wipe the original position on the windshield clean. If there's residual adhesive, use an alcohol wipe to remove it. If the device itself isn't damaged, replace it with a new piece of 3M adhesive (you can buy a roll for ten dollars at an auto parts store). Align it to the right side of the rearview mirror, press firmly for one minute, and hold it in place. Finally, open the ETC app and click 'Reactivate Device.' Just keep your phone's Bluetooth within 10 centimeters of the windshield during the process. Last time, it only took me fifteen minutes from when the device fell off to getting it working again.
