What Does ETC Displaying 'Label Detached' Mean?
2 Answers
ETC displaying 'Label Detached' means the device is currently unusable and needs to be reinstalled and reactivated at the original bank processing point, designated agent offices of the traffic management bureau, or any expressway ETC service center. The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. A red light will briefly illuminate, and the OLED screen will display 'Tag Invalid' or 'Please Insert Card,' indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. ETC Activation Method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays 'Bluetooth On.' If 'Tag Invalid' appears when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on top of the electronic tag to enable Bluetooth directly. Turn on your phone's Bluetooth and open the corresponding mobile app (usually with a download QR code on the electronic tag) to access the device activation interface. Click 'Connect Device' and wait patiently for the 'Connection Successful' prompt. Once connected, upload a photo of the vehicle's front to complete activation.
I once heard about this issue, the ETC tag showing 'removed' means that the small device installed on the car's windshield has been taken off or loosened. You might have encountered this prompt when entering the highway, indicating that the system cannot detect the device functioning properly, making automatic toll collection impossible. There are quite a few reasons for this, such as the device getting loose from bumps while driving, accidentally knocked off during car washing, or some car owners trying to remove it for adjustments and ending up damaging it. If the tag is removed, your ETC lane passage will fail, forcing you to use the manual lane to pay, wasting time and even risking fines or penalty points. I think this situation is the most annoying, especially if you end up stuck in a long queue at the toll booth. It's best to regularly check if the tag is securely installed and avoid tampering with it. If there's an issue, visit an ETC service center—they can replace the tag for free. My friend solved it this way, hassle-free and safe.
