How to Reactivate a Fallen ETC Device?
2 Answers
Methods to reactivate a fallen ETC device: Insert and remove the ETC card twice consecutively until the electronic tag screen displays 'Bluetooth On'. If 'Tag Invalid' appears when inserting/removing twice without the electronic tag attached, this is normal and won't affect reactivation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile APP (usually with a download QR code on the electronic tag), and enter the device activation interface. Click 'Device Connection' and patiently wait 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 section of the front windshield. For large vehicles like trucks and buses, the installation position is on the lower middle section.
Last time my ETC fell off, I managed to reactivate it myself, and it was quite simple. First, clean the windshield area thoroughly—alcohol wipes work best for removing grease film, then let it dry. Next, peel off the double-sided tape on the back of the device and reattach it, making sure to press firmly for about ten seconds to ensure the adhesive sticks. The best position is behind the rearview mirror on that black dotted area—it won’t obstruct your view and holds securely. Then, open the official ETC app, find the device activation option, and pair your phone’s Bluetooth with the ETC device’s Bluetooth. Just follow the on-screen instructions—the whole process takes about five or six minutes. If you’re doing it yourself, make sure your car is parked in an area with good network coverage, and avoid moving the device during activation. If it doesn’t work after a few tries or if the device is damaged, it’s easier to just head to a highway service point and let the staff handle it.
