How to Restore a Removed ETC Tag?
2 Answers
The anti-removal guide rod on the back of the ETC electronic tag is essentially a reset button switch. Once the button pops out, the information inside the ETC device is lost, and it needs to be reactivated by re-entering the information. You can try the ETC self-activation method. If that doesn't work, you will have to take it to an ETC service point or ETC service center to reactivate or cancel the ETC and replace it with a new ETC electronic tag. ETC Installation Process: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-removal button on the back of the OBU. The red light will briefly turn on, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield, ensuring the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation location. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is inserted into the OBU device. Benefits of Installing ETC: Saves time by eliminating the hassle of waiting in queues. Environmentally friendly—vehicles can pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution. Reduces wear and saves costs by decreasing the frequency of vehicle starts and stops, lowering wear and fuel consumption. Users also enjoy a 5% discount on toll fees. Improves efficiency—ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
Having driven for many years, I've accidentally removed and reattached my ETC tag several times. Experience tells me to first locate the original position on the windshield, thoroughly clean it with a wet cloth and alcohol to ensure no grease or dust remains. Then carefully reattach the tag, pressing firmly with the built-in adhesive tape, and wait a few minutes for the glue to set. Choose a position directly in front of the driver's seat, avoiding edges to prevent weak signals. After starting the car, check if the tag light turns on; if there's no response, it likely needs reactivation—I usually drive to the nearest highway service point for staff to handle it quickly, which solves the problem. Removing the tag might damage internal components, such as breaking from a fall, in which case you'd need to contact the ETC company for a replacement. For maintenance, regularly wipe the tag to preserve adhesion and avoid high-pressure car washes that could dislodge it. Following these steps ensures smooth passage through toll stations—safe and convenient.
