What does it mean when the ETC displays 'Label Disassembled'?
3 Answers
ETC displaying 'Label Disassembled' indicates that the device is currently unavailable and needs to be reinstalled and reactivated at the original processing point or any highway ETC service center. Most ETC label disassembly cases occur when users remove the ETC device to replace the battery, or it may be due to the anti-tamper button on the back of the OBU device popping up and locking, or the OBU device being detached. The ETC system uses automatic vehicle identification technology to establish wireless data communication between vehicles and toll stations, enabling automatic vehicle recognition and exchange of toll-related data. It employs computer networks to process toll data, achieving a fully automatic electronic toll collection system without the need for vehicles to stop or toll booths. The ETC system facilitates wireless communication and information exchange between the onboard unit installed in the vehicle and the antenna installed on the toll station lane.
When the ETC displays 'Tag Detached,' it means the small in-vehicle device may have come loose or been removed. I’ve encountered this several times while driving on the highway—initially, I thought it was broken and got really nervous. Later, when I took it to a repair shop, the technician said the adhesive might have failed or the tag wasn’t properly secured during installation, making it prone to falling off due to vibrations. I had to manually pay at the exit and then get the tag fixed. To avoid this, I now regularly check the tag’s position before car washes and reinforce it with double-sided tape. Friends also shared their experiences: if the tag falls off and isn’t addressed promptly, the ETC function will be suspended, making highway travel even more troublesome. My advice is not to panic—safety first—park properly and fix it slowly or seek help from a service point.
The ETC tag detachment alert usually indicates that the small device attached to the windshield has come loose or isn't secured properly, possibly due to improper installation, long-term vibration loosening, or human factors. I've dealt with this issue myself, and the solution starts with simple checks: first, verify if the tag is still in place and whether the mounting clip is damaged. If it's not a hardware issue, it's best to visit an authorized service point for professional reset or replacement. If you encounter this on the highway, don't panic—simply use manual payment methods. For prevention, regularly clean the adhesive area to avoid dust buildup and minimize sudden braking to reduce vibrations. This is a common but straightforward issue; proper maintenance can save a lot of hassle.
