Is it normal for ETC not to light up?

ETC installation does not require external power connection as it uses its own built-in power source. The ETC electronic tag consumes power, but during normal use, there is no need to charge the battery because there is a solar panel on the back of the battery that can charge itself. During installation, it is necessary to avoid the black areas on the windshield. The built-in power source of ETC typically has a battery life cycle of 3-5 years. ETC stands for Electronic-Toll-Collection, which means electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is handled by a non-owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed, and the applicant must be between 18 and 60 years old and own the vehicle. How ETC works: The vehicle-mounted electronic tag installed on the windshield communicates with the microwave antenna in the ETC lane at toll stations. Through computer networking technology, the system settles transactions with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay the toll. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions as vehicles pass through toll stations without stopping; Cost-saving: Reduces vehicle start-up and braking frequency, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
I've also encountered the issue of the ETC light not turning on while driving, and at first, I was quite worried it might be a serious problem. Actually, in many cases, this is quite normal. For example, when the car is parked, the ETC system isn't activated, so the light automatically turns off to avoid wasting electricity—similar to a phone screen going to sleep, it's just a power-saving mode. However, if the light not turning on is accompanied by failed toll charges or no response at toll stations, then there's definitely a problem. Possible issues could include a blown fuse, unstable battery voltage, or the ETC device itself aging or malfunctioning. I recommend first checking your car's fuse box and trying to replace the fuse. If that doesn't work, it's best to visit a 4S shop as soon as possible for a check-up, since ETC problems can easily lead to incorrect charges or getting stuck in the toll system. During regular maintenance, remember to ask the technician to pay extra attention to these small details—it can save you a lot of hassle.
