How to Reactivate ETC After Removal and Reinstallation?
3 Answers
Method for reactivating ETC after removal and reinstallation: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth On". If "Tag Invalid" appears when inserting/removing twice without the electronic tag attached, this is normal and doesn't affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth and open the corresponding mobile APP (usually with a download QR code on the electronic tag), then enter the device activation interface. Click "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 like cars and minivans, the ETC card and OBU device should be installed on the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is on the lower middle part.
I reinstalled my ETC by myself not long ago and finally figured it out after some effort. You know that little white box has an anti-tamper button on the back - it pops up and automatically locks when removed. To reattach it to the windshield, you need to press and hold that button until the green light starts flashing for activation. The key is to align it properly and apply firm pressure, ideally letting the adhesive dry completely to prevent loosening from road vibrations. I recommend doing this at midday when the sun's strong - the warmer glass helps the adhesive bond better. If the light doesn't come on, don't panic - just connect to the ETC via your phone's Bluetooth and hit 'reactivate' in the app (assuming your device has Bluetooth capability). If all else fails, just visit the bank counter - their specialized equipment can reset it with one swipe.
Reattaching the ETC requires attention to the operation sequence. My habit is to first clean the installation area on the windshield, thoroughly wiping off any old adhesive residue. When taking out the device, don't rush to attach it—remember to insert and remove the traffic card from the slot two or three times to reset the chip connection. Then, press the anti-tamper button firmly with one hand while attaching the device with the other, maintaining pressure for 30 seconds. Last time, I didn't hold the button and just stuck it on directly, resulting in a wasted trip to the highway toll gate. After activation, pay attention to the indicator light—it should flash green continuously to indicate success. If you attach it too close to the black grid area, signal interference might occur. The best spot on the front windshield is the area to the right of the rearview mirror.
