What to Do When ETC Light Doesn't Turn On?
2 Answers
When the ETC light doesn't turn on, you can reactivate it or replace the ETC device. Here are the relevant details: 1. New Device: For newly received ETC electronic tags (OBU devices), if the screen displays "Tag Invalid" or "Please Insert Card," it indicates the device is functioning normally and does not affect activation. 2. Installation Position: When installing ETC, it is necessary to visit a professional service outlet. The ETC should be installed on the front windshield of the car, typically in the middle position, as this placement does not easily obstruct the driver's view.
Seeing the ETC device not lighting up? I've encountered this situation before, and it's quite common. The most likely reason is that the device isn't receiving power. First, check if the device has become loose—unplug it and firmly reconnect it to the cigarette lighter socket. If it still doesn't light up, then you'll need to check the fuse—open the car's fuse box and look for the corresponding cigarette lighter fuse to see if it's blown. If it is, replace it with a new one. If that doesn't work, test whether the cigarette lighter itself is functional by plugging in a phone charger or another small appliance. If the fuse keeps blowing repeatedly, there might be a short circuit in the vehicle's wiring. Sometimes, the device itself may be aging or malfunctioning, such as a dead internal battery or damaged components. An ETC device not working can be troublesome on highways, often causing traffic jams at toll booths. If self-inspection doesn't resolve the issue, it's recommended to visit a 4S shop or a professional repair shop to check the power module. Regular maintenance can prevent such problems—keeping car devices clean and free of dust buildup helps.
