ETC needs to be reinstalled and reactivated after falling off. The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly illuminate. The OLED screen will display "Label Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield, ensuring the surface is smooth, clean, and dry. Then, peel off the adhesive backing of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield. The chip should be inserted into the OBU device. Method to activate the ETC device: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth On." If the screen shows "Label Invalid" when inserting and removing twice without attaching the electronic tag, this is normal and does not affect activation. Alternatively, press the button on the top of the electronic tag to enable Bluetooth. Turn on the phone’s Bluetooth and open the corresponding mobile app (usually a download QR code is provided on the electronic tag). Navigate to the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt. After successful connection, upload a photo of the vehicle’s front to complete activation.

VTEC Oil Pressure Switch Circuit Too High?

VTEC oil pressure switch circuit being too high may be due to the need for an oil change or a faulty VTEC solenoid valve. 1. Reasons for VTEC oil pressure switch circuit being too high: The need for an oil change and a faulty VTEC solenoid valve. If the solenoid valve fails to open, oil cannot enter the rocker arm chamber, keeping the rocker arm oil pressure switch in a closed state, which results in excessively high voltage in the switch circuit. 2. Inspection and repair: (1) Check if the solenoid valve's ground and power supply wires are shorted to the positive terminal. (2) Verify whether the pressure signal feedback from the pressure switch is normal. (3) Check if the solenoid valve is functioning properly. (4) Inspect if the pressure switch is operating correctly. (5) Examine the oil pressure in the VTEC system's oil passages.

How to Switch Between Hybrid Modes?

Hybrid vehicles are automatically controlled by the computer system. The engine will engage when the car reaches a certain speed, and you can also manually switch between hybrid mode and pure electric mode. Advantages of hybrid vehicles: 1. Fuel efficiency—in congested urban areas, the internal combustion engine can be turned off, allowing the battery to power the car, which also reduces pollutant emissions. 2. With a battery, the car can efficiently recover energy during braking, idling, and downhill driving. 3. Being a hybrid, you don’t have to worry about the high energy consumption issues faced by pure electric vehicles, such as air conditioning and heating. 4. Strong starting power—during acceleration, the electric motor in a hybrid car can effectively compensate for the low-torque weakness of the internal combustion engine at low speeds.

What is the front brake type of the Infiniti Q60?

The front brake type of the Infiniti Q60 is ventilated disc. Ventilated disc brakes utilize centrifugal force generated during vehicle motion to create air convection, achieving effective heat dissipation. Externally, they feature numerous holes drilled toward the center around the circumference. These holes are manufactured through a specialized process, providing significantly better cooling performance compared to standard solid disc brakes. The Infiniti Q60 is a sports car under the Infiniti brand, equipped with a 2.0-liter turbocharged engine across all variants. It delivers a maximum power output of 211 horsepower and a peak torque of 350 Newton-meters. The engine reaches its maximum power at 5,500 RPM, while the maximum torque is available between 1,500 to 3,500 RPM. The vehicle is paired with a 7-speed automatic transmission (7AT).
