What to Do When the ETC Device Falls Off?
2 Answers
If the ETC device falls off, it cannot be used anymore. You need to bring the original vehicle, the ETC device, and the bound bank card to the installation location of the ETC device to reactivate it. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. The red light will briefly turn on, and the OLED screen will display "Label Invalid" or "Please Insert Card," indicating that the device is functioning properly. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the protective film on the back of the OBU and stick it to the installation position. Press firmly with your hand 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. The chip should be inserted into the OBU device.
When the ETC device fell off the windshield, I first found a safe place to park, avoiding changing lanes on the highway to prevent traffic disruption. After getting out of the car, I picked up the device to check for any cracks. If the exterior was intact, I tried reinstalling it: I wiped the dust and grease off the glass with a damp cloth, then dried it with a paper towel. I applied some spare adhesive (available online) to the ETC base and pressed it firmly against the original spot for a minute or two. After reattaching it, I didn’t rush back on the road—I went to a nearby ETC testing point to check if the indicator light turned green, confirming normal card reading. If it malfunctioned, I immediately contacted the bank’s customer service or visited an ETC service center for repairs, avoiding delays to prevent extra charges. Last time it fell off, it was due to summer heat softening the adhesive, and replacing the glue fixed the issue. Usually, parking in shaded areas helps extend the adhesive’s lifespan and prevents this problem.
