What is the reason for the ETC screen not lighting up in the car?

[LeAubree]

The reasons for the ETC screen not lighting up in the car are: 1. The electronic tag is not inserted correctly; 2. Unauthorized removal of the in-vehicle electronic tag will render it unusable; 3. The vehicle's windshield is covered with a metal explosion-proof film; 4. OBU transfer or replacement requires visiting a service outlet. ETC (Electronic Toll Collection) operates through dedicated short-range communication between the in-vehicle electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations. It utilizes computer networking technology for backend settlement processing with banks, enabling vehicles to pass through highway or bridge toll stations without stopping to pay the fees.
