ETC Activation Method After Removal: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth On". If "Tag Invalid" appears when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, you can directly press the button on the top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually there is a download QR code on the electronic tag), and enter the device activation interface. Click on device connection and patiently wait for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation. ETC Installation Process: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-removal button on the back of the OBU; a red light will briefly turn on, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the protective film on the back of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device.

Hey buddy, if you remove and reinstall the ETC device, it needs reactivation! I went through this when replacing my windshield. The key is to press the anti-tamper switch on the back of the device—that little button under the rubber pad. Nowadays many new devices can be activated via mobile apps: just turn on Bluetooth to connect the device and follow prompts to upload vehicle license photos. However, older models still require a trip to the bank or expressway service point for professional reactivation. Remember to align it properly during reinstallation—misalignment may cause recognition failure. Best to test immediately after installation; if it doesn't beep at toll gates, you'll need to redo it.

What is the reason for the pedal shaking at startup but running smoothly afterwards?

The reasons for the pedal shaking at startup are as follows: 1. Belt: The trembling phenomenon when a motorcycle starts or at low speed is largely due to the long-term dynamic friction between the shoe blocks of the rear clutch plate and the housing in the belt box. 2. Slipping: The surface of the shoe blocks is contaminated by friction powder or dust from the air inlet in front of the belt box, reducing the friction between the shoe blocks and the housing, thus causing slipping. At this time, the vehicle will have a trembling sensation when starting or at low speed. 3. Reason for no shaking at startup: The reason why the vehicle shakes at startup or low speed but not at high speed is that the load at startup is much greater than the load at high speed, and the maximum static friction of the same object is greater than the maximum dynamic friction.

Can a car be licensed anywhere?

Cars can be licensed in different locations, and the car dealership can assist in handling license plates for various cities within the province. License plate registration period and considerations: The state does not have clear regulations on when a car must be registered after leaving the factory. After purchasing a car, based on the validity period of the temporary license plate (generally 15 to 30 days), the vehicle must be registered. Car registration can be processed across regions, but it must comply with local environmental emission standards. The vehicle purchase tax must be paid in the city where the license plate is registered. Different regions may issue different types of license plates. For specific details, consult the local vehicle management office. Documents required for license plate registration: ID card, vehicle qualification certificate, vehicle parameter sheet, car invoice (second and fourth copies), vehicle purchase tax, car insurance policy, purchase invoice, vehicle qualification certificate, ID card or organization code certificate and copies for invoice issuance, compulsory insurance policy, tax payment certificate, and a temporary residence permit for non-locals.
