What does OBU anti-tamper failure mean?

[VonEzra]

OBU being disassembled may be due to the user privately removing or moving the OBU device, causing it to fail. It could also be because the ETC electronic tag fell off or became loose, triggering the anti-collision and anti-tamper switch, leading to OBU failure. In such cases, it is necessary to visit the ETC service point at the highway management office to reactivate the OBU. Below are the relevant details: 1. Unauthorized disassembly: Once the electronic tag is installed, it must not be disassembled without permission. If disassembled, the anti-tamper switch on the electronic tag will be triggered, causing the internal push rod to extend, rendering the ETC ineffective. When passing through the ETC lane on the highway, it will display "OBU (electronic tag) tampered" and normal passage will be denied. 2. Reset application: If the ETC tag fails, you can visit the bank branch that handles ETC services or the highway service office to apply for a reset.
