Why does ETC fail after replacing the windshield?

[MacMiles]

After replacing the windshield, the ETC becomes invalid because there is a small button on the back of the ETC device. Once the ETC is removed, this button will automatically pop out. When the button pops out, all the information will be reset to zero. This is why the ETC stops working after being removed. You can go to the bank where you originally applied for the ETC to request a new one. The bank will take back the old device and you can reapply for a new one. ETC 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 attaching the electronic tag, this is normal and does not affect activation. Alternatively, you can 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 "Device Connection" and wait patiently for the "Connection successful" prompt. Once connected successfully, upload a photo of the front of your vehicle to complete activation.
