Why is the ETC display screen not lighting up?

1 Answers

The reasons why the ETC display screen is not lighting up are: 1. It is in standby mode; 2. The ETC device has no power. The methods to determine if the ETC is functioning normally are: 1. Remove the ETC card; 2. Reinsert the ETC card into the electronic tag; 3. After hearing a beep sound, if the electronic tag screen displays "Toll Card" or the balance, it proves that the ETC is in normal working condition. ETC is an automatic toll collection system for highways or bridges. It uses dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station. By leveraging computer networking technology and backend settlement processing with banks, it achieves the purpose of allowing vehicles to pass through highway or bridge toll stations without stopping to pay toll fees.

What are the reasons why a car always runs out of battery?

The reasons why a car always runs out of battery are: 1. The car has been left unused for a long time, during which the battery self-discharges; 2. The electrical appliances inside the car were not turned off during use, resulting in prolonged discharge; 3. The car battery has aged. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine stops running or is at low idle, it powers the car's electrical equipment; 3. When the generator's output is insufficient, it can assist in supplying power to the electrical equipment; 4. It mitigates voltage surges in the electrical system, protecting the car's electronic devices; 5. It can store excess electricity generated by the alternator.

How many kilometers can a car run after the gasoline gauge light comes on?

When the car's gasoline gauge light comes on, it can still run for 40 to 60 kilometers. The function of the fuel gauge is to display the fuel level in the car's fuel tank. The fuel gauge consists of a voltage regulator, a fuel indicator, and a fuel level sensor. The low fuel level warning device is designed to illuminate immediately when the fuel in the tank falls below a specified level, alerting the driver to take notice. Precautions for using the fuel gauge include: 1. Do not wait until the warning light comes on to refuel; too little fuel is detrimental to the normal operation of the fuel pump and can reduce its service life. 2. Indication deviation: When replacing the battery or fuel filter, the fuel gauge pointer may show a lower level than before after restarting the vehicle. This is due to pressure release after opening the fuel tank, causing the fuel level to drop, and such display deviation is a normal phenomenon.
