How to test if ETC works after installation?
2 Answers
After ETC installation, the staff will activate it for the vehicle owner. The activation process itself serves as a signal test - successful activation indicates normal signal reception, meaning the vehicle can properly pass through ETC lanes. The Electronic Toll Collection (ETC) system represents the world's most advanced road/bridge toll collection method. ETC operates via microwave-dedicated short-range communication between the onboard unit (OBU) installed on the vehicle's windshield and the microwave antenna in toll station ETC lanes. This system utilizes computer networking technology for backend settlement processing with banks, achieving non-stop toll payment when vehicles pass through road/bridge toll stations.
Testing ETC after installation is quite simple. I usually drive to a low-speed toll station first, such as the nearest expressway entrance, and observe whether the barrier automatically lifts when passing through the ETC lane. A green indicator light means it's working properly. If the barrier doesn't lift or the light turns red, check if the device is firmly attached without looseness, the card is inserted correctly, and the account has sufficient balance. For safety, choose a less busy time to test to avoid blocking traffic during peak hours. Regularly check transaction records via the official ETC app to confirm normal deductions. If the test fails, reinstall the device or contact after-sales service to avoid damaging it by improper disassembly. Remember to keep your speed moderate during testing, maintaining 20-30 km/h to ensure reliable activation.
