ETC Tag Reactivation Method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays " On." If it shows "Tag Invalid" when inserting and removing twice without the electronic tag attached, this is normal and does not affect reactivation. Alternatively, you can directly press the button on the top of the electronic tag to enable Bluetooth. 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. Once connected, upload a photo of the vehicle's front to complete the activation. ETC Installation Process: 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 turn on, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then, peel off the adhesive backing of the OBU and stick it to the installation position, pressing 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.

Last time my ETC tag suddenly stopped working too, and it took me a while to figure out it was due to a loose device causing poor signal contact. You'd better first check if the tag's adhesive position has loosened or shifted. You can try using a hairdryer to slightly heat the tag's adhesive backing and reattach it firmly. If it still can't be recognized after passing the toll station, quickly check if the device has expired or if there are unpaid fees—some provinces require reactivation of the service every three years. I directly contacted the bank customer service where I applied for it and scheduled an appointment at the nearest service point. Just bring your ID card and vehicle registration for a free reactivation. By the way, a reminder: now most highway toll stations have ETC service centers that can help with these issues, and you won’t even need to queue if you go on weekends.

From my experience, ETC failure is mostly due to the device running out of , especially in summer when high temperatures can damage the backup battery. First, clean the solar panel with a cotton swab and place it in a sunny spot on the windshield for half a day to see if it charges. If the solar panel still doesn't charge, visit an ETC service center to replace the device. Remember to bring your vehicle license and original ID card. Nowadays, you can also use Alipay to book a self-service machine for the replacement, which takes only ten minutes. After activation, it's advisable to test the device's sensitivity by entering and exiting a toll station before taking a long highway trip to avoid long queues later.

Don't panic if your ETC fails. First, check the status in your ETC mobile app. If there's a balance due, top up and it should recover within half an hour. For expired devices, visit a service point for reactivation—remember to clean the black dot area on your windshield before reattaching to avoid signal interference. If the device is swollen from sun exposure, you'll need to pay for a replacement; it costs 120 yuan at the service center and is ready immediately. After reactivation, ensure the staff tests it with a card to confirm proper signal reception—otherwise, highway trips could be troublesome.

Last time my ETC failed was due to speeding through the barrier, which caused the tag to be locked. Handling this is a bit more troublesome: first, go to the bank to remove the blacklist status, then visit the highway office to unlock it. Now, you can check the locking reason via WeChat mini-programs—just enter your license plate number to see the service outlet addresses. Reactivation requires visiting two places, so it's best to bring your bank card and vehicle documents. The whole process takes about half a day. Later, I found out it was a film installation issue affecting signal reception. Now, I always ask the film installer to leave a transparent square window in the ETC area.

New drivers should be aware that ETC tags must not be removed arbitrarily, as the rear button will pop up and lock the device if detached. If this happens, do not force it back in. Instead, take the device to the bank for resolution. A colleague of mine once peeled it off and reattached it himself, resulting in the ETC lane being inaccessible on the highway. It is recommended to directly visit the issuing bank to unlock and reactivate the device. The new models now use pairing mode—simply turn on your phone's Bluetooth and bring it close to the tag to complete activation, which is much more convenient than the older versions. After activation, remember not to exceed 20 km/h when passing through the toll gate, as speeding may trigger another lock.
