How to Reactivate a Loose ETC?
2 Answers
ETC reactivation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays 'Bluetooth On'. If it shows 'Tag Invalid' when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, you can directly press the button on top of the electronic tag to turn on the Bluetooth function. 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 vehicle's front to complete activation. ETC installation positions: For small vehicles such as cars and minivans, the ETC card and OBU device are installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the middle lower part.
I've experienced my ETC device coming loose several times, usually due to aging adhesive on the windshield. Reactivation steps: First, park the car in a safe place, turn off the engine, carefully remove the loose device, and clean the glass and the bottom of the device with alcohol wipes to remove grease and dust. Then, replace it with a new piece of strong double-sided tape, such as 3M brand, and slowly press the device firmly against the glass for more than 15 seconds without leaving any bubbles. After installation, drive to the nearest highway ETC lane to test if the barrier lifts normally; if it fails, the device may have shifted and damaged the signal, requiring contact with ETC customer service via the app or phone to request reactivation. Preventive measures: Regularly check the adhesive tape, especially on hot days; choose an installation point not too close to the edge of the glass to reduce vibration risks. It's recommended to check during annual maintenance to avoid temporary parking hassles, as ETC failure can affect highway traffic efficiency and safety.
