How to Reactivate ETC After It Becomes Loose?
2 Answers
Methods to reactivate ETC: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth is on". If "Tag Invalid" appears when inserting and removing twice without the electronic tag attached, this is a normal phenomenon and does not affect reactivation. Alternatively, you can directly press the button on the top of the electronic tag to turn on the Bluetooth function. Turn on the mobile 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 should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part.
Last time my ETC card came loose, I didn’t even realize what was wrong when it caused issues at the toll booth—what a hassle. First, check if it has fallen off or is misaligned. If it’s still in place but just loose, clean the windshield area with alcohol, let it dry, and then press it firmly back into position. If it’s fallen off, be careful—there’s a small anti-tamper switch inside the device; once loosened, it self-locks and deactivates. I tried fixing it myself with double-sided tape, but you’ll need to contact ETC customer service or visit an installation point to reactivate it. Usually, you can also initiate the reactivation process via the mobile app. To avoid trouble, I recommend glancing at the ETC device before driving to ensure it’s secure, and regularly cleaning the windshield to reduce the risk of loosening—saving you the hassle of traffic jams and unnecessary repair costs.
