Why is the ETC light not on?
2 Answers
The reasons why the ETC light is not on are: 1. The ETC device is damaged; 2. The ETC device is out of power. The method to install ETC is: 1. Peel off the double-sided adhesive plastic film on the back of the ETC device and stick it to the position behind the rearview mirror at the top of the windshield; 2. Press firmly for about 10 seconds after sticking; 3. Insert the card into the ETC device repeatedly several times. Precautions for using ETC include: 1. The ETC transaction sensing area is 8 meters. To prevent the ETC device failure of the vehicle in front, keep a distance of more than 10 meters from the vehicle in front; 2. The recognition speed of the ETC lane is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, which will lead to charging failure; 3. When using a debit card to bind ETC, insufficient balance will also lead to charging failure.
I once encountered a situation where the ETC light didn't turn on, and it was particularly embarrassing on the highway because the toll station didn't detect it, resulting in having to pay an additional fee. Later, when I got home and checked, I found that the cigarette lighter adapter was loose, and simply plugging it back in fixed the issue. In fact, the most common reason for an ETC light not turning on is a power disconnection, such as a poorly connected cigarette lighter adapter or aged and broken wiring. Additionally, if the device's internal battery has been used for a long time, it can also drain, especially in older ETC models where the built-in battery might wear out after a few years. If the device is completely broken, you'll need to visit a service center to get a replacement—fortunately, many apps now allow you to schedule a diagnostic check in advance. Personally, I recommend checking whether the ETC light is functioning properly before driving, especially before entering a highway, as a small oversight can cause delays. Regularly cleaning dust off the device's surface can also help prevent malfunctions. If you can't fix it yourself, contacting a professional installation point is the safest option.
