How to Check if the ETC Device is Working Properly?
2 Answers
Methods to check the ETC device: 1. First, check if the ETC card and OBU (On-Board Unit) are damaged: Press the anti-tamper button on the back of the OBU. The red light will briefly turn on, and the OLED screen will display "Label Invalid" or "Please Insert Card," indicating the device is functioning normally. 2. Take it to the bank where you applied for the ETC or the highway service center for inspection: The ETC device has an internal battery with a typical lifespan of over 3 years. If the ETC screen is not working or there is no response when pressing the top button, it might be out of power. You can take it to the bank where you applied for the ETC card or the highway service center for inspection. 3. Check if the OBU device or ETC electronic tag is loose or detached: Unauthorized removal or movement of the OBU device, detachment, or looseness of the ETC electronic tag will cause the electronic tag to become invalid, and the screen will display "Label Invalid." In such cases, you need to take it to the ETC bank branch or highway service center for processing. If the damage is not caused by human factors, it only requires reactivation.
I've been driving for over a decade and always make it a habit to check my ETC status before heading out to ensure it's working properly. Here's how: Stand by the car window and check the indicator light above the device—a steady green means everything's good. You can also drive near a highway toll station and try the dedicated test lane; hearing a 'beep' as you pass confirms it's working. Additionally, don't forget to check if the device is securely installed—no looseness or cracks—and wipe it with a damp cloth if it's dirty. Keep an eye on your account balance too; just open your mobile banking app for a quick look to avoid being denied entry due to insufficient funds. If there's no response, I visit the nearest bank branch or service center for help. Maintaining this habit regularly keeps trips worry-free, especially checking before long journeys to avoid delays from unexpected congestion.
