What to do when ETC sometimes doesn't respond?
1 Answers
If your ETC sometimes doesn't respond, you can go to the ETC expressway to check, or pull over after exiting the toll station and ask the toll station staff. There are mainly 4 reasons why ETC may not respond: 1. Driving too fast through the ETC lane: Currently, the recognition speed at ETC toll stations in China is 30km/h. To ensure successful recognition, it is recommended to keep your speed below 20km/h, otherwise the vehicle information may not be recognized. Additionally, if you drive too fast and the distance to the vehicle in front is less than 10 meters, you might end up paying for the vehicle in front. 2. The ETC tag has expired: In this case, the ETC display will usually show messages like "No OBU" or "Electronic tag expired." This happens if the ETC device becomes loose, falls off, or is dismantled, causing the anti-tamper switch to pop out and reset all data. 3. ETC has no power or other malfunctions: There is no exact rule for how often to charge ETC devices. For solar-powered ETC devices, even if not used frequently, it is recommended to charge them every 3 months to avoid affecting their lifespan due to battery self-discharge. 4. Using someone else's ETC card: The ETC card inserted in the OBU will be detected by the RUS in the lane, using the electronic tag to communicate with the lane antenna via microwaves, automatically completing the entry/exit information reading and payment without stopping, recording the vehicle information and deducting the toll. At the same time, the lane barrier will automatically lift, allowing the vehicle to pass. One vehicle can only use one ETC card, but one ETC card can be bound to multiple vehicles for payment.
