How to Check if the Transmission Fluid is Sufficient?

[VivienneLynn]

ETC behind is the anti-tamper switch, which will automatically deactivate once released and cannot be reactivated by ordinary users. The ETC system utilizes microwave technology to identify the unique code of the vehicle's ETC device through the signal transceiver of the lane-side control system, determine vehicle type information, calculate toll fees, and automatically deduct the toll from the user's dedicated account. The automatic activation method for ETC is as follows: 1. There is a socket in the ETC where the ETC card can be inserted. Before the electronic tag displays "Bluetooth on," insert and remove the ETC card twice consecutively. If the electronic tag is not attached, displaying "Tag invalid" is not normal; simply press the button on the upper part of the electronic tag. 2. Turn on Bluetooth on your phone and open the corresponding app or mini-program. 3. Click "Device Connection," select the device model to connect, and wait for the "Connection successful" prompt. 4. After successful connection, follow the prompts to complete verification by uploading a front photo of the vehicle. Wait for a review period of 3 to 5 days; once approved, it can be used normally.
