ETC Electronic Tag Failure?
2 Answers
ETC displaying 'tag failure' indicates that the ETC electronic tag is not activated. You need to bring the ETC device to an ETC service center or ETC service outlet for inspection. If the failure is not caused by human factors, a simple secondary activation of the ETC will restore its functionality. How ETC Works: Through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, ETC utilizes computer networking technology to process background settlements with banks. This enables vehicles to pass through highway or bridge toll stations without stopping to pay fees. Where to Install ETC: For small vehicles such as cars and minivans, the ETC card and OBU device should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part.
I've experienced ETC electronic tag failures several times and summarized several common causes. First, the battery is depleted. There's a non-replaceable battery inside the tag, typically lasting three to five years. If you drive the car for a long time without replacing it, problems are likely to occur. Second, device malfunctions, such as aging circuit boards or damaged sensors. Third, incorrect installation position. If the tag is attached to the windshield and exposed to prolonged sunlight or becomes loose, it can affect signal reception. Fourth, significant interference during use, such as when entering or exiting tunnels or in areas with many electromagnetic devices nearby. It's recommended to regularly check the status of the indicator light. If the tag fails, first ensure the card is securely inserted. If that doesn't work, go to a service center for testing and updates. Don't delay repairs to avoid inconvenience on the highway.
