How to test if your ETC is working

Methods to test if your ETC is functioning properly: After successful activation of the ETC device, inserting the ETC card should display corresponding vehicle information or ETC card account balance. For some ETC devices, the relevant working indicator light will illuminate, which proves the ETC device is operating normally. If the ETC light doesn't turn on or the screen remains black, and there's no response when pressing the top button or inserting the ETC card, it's possible that the ETC device has no power or is damaged and needs to be tested or replaced at an ETC service outlet. ETC electronic toll collection lanes, also known as electronic toll platforms, refer to China's expressway network toll collection system. Vehicles can automatically pay tolls without passing through toll booths, achieving convenient expressway access.
When testing whether my ETC is functioning properly, I usually follow several steps. First, I check if the green light on the ETC device attached to my windshield is illuminated, as this indicates the device is powered on and operating normally. If there's no light, it might be due to a dead battery or loose power connection, so I inspect the charger connection and fuses inside the car. Second, I drive slowly (around 15-20 km/h) to the entrance of a nearby ETC lane to see if the toll gate lifts automatically; if it does, it confirms smooth signal transmission and usability. Third, I simultaneously open the ETC service app on my phone to check if the account balance is sufficient or if there are any abnormal alerts, as account issues can also cause ETC failure. If all these checks pass, I can generally confirm it's working well. Occasionally, I clean the device's surface to prevent dust from interfering with the signal or visit a highway service point for a free test before long trips to avoid unexpected malfunctions. Safety first—testing during off-peak hours is more reliable.
My method for testing the ETC is quite simple and practical, starting with daily habits. First, take a glance at the indicator light on the device—a flashing green light means it's working normally, while a red light or no light indicates the need to replace the battery or check the wiring. Next, I take advantage of the quieter afternoon hours to drive through the ETC lane at a toll station, observing the response of the barrier; if it lifts quickly with a beep, then it's good to go. For peace of mind, I like using the diagnostic feature in the mobile app, entering the license plate number to check the status feedback and review recharge records to prevent balance shortages or malfunctions. If issues arise, such as weak signals, I directly contact the ETC service hotline or online customer support for quick resolution, avoiding unnecessary trips. Additionally, I recommend performing simple maintenance on the device annually, like cleaning dust from the slot or testing the car's cigarette lighter socket for proper power supply. Developing these habits can prevent awkward situations on the highway.
