A wrench symbol appearing on the dashboard is a maintenance reminder light, indicating that the vehicle has reached its scheduled service interval and should be taken to a 4S dealership for maintenance. This warning light will be reset after the service is completed. The maintenance cycle is pre-programmed during vehicle manufacturing, so the wrench symbol will periodically appear at predetermined mileage intervals to remind owners to perform timely maintenance. Automotive maintenance refers to preventive work involving regular inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain components, also known as vehicle servicing. Modern car maintenance primarily covers engine systems, transmission systems, air conditioning systems, cooling systems, fuel systems, power steering systems, and other related components.

Why is there no fee deduction displayed after passing through the highway with ETC?

The reason why there is no fee deduction displayed after passing through the highway with ETC is: the deduction is not in real-time, and most of the time it is delayed for a few days before being processed. ETC works through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station. It uses computer networking technology to perform backend settlement processing with the bank, achieving the purpose of vehicles passing through highway or bridge toll stations without stopping to pay the fees. The reasons why ETC may not be detected include: 1. The electronic tag is not inserted correctly; 2. Unauthorized removal of the onboard electronic tag will render it unusable; 3. The vehicle's windshield has a metal explosion-proof film; 4. OBU transfer or replacement requires visiting a service center.

Why Does the Engine Speed Increase Automatically in Neutral Gear?

There are two main reasons for a sudden increase in engine speed when the vehicle is in neutral: a faulty carbon canister solenoid valve causing the engine speed to rise suddenly in neutral, and a malfunctioning vacuum sensor in the braking system leading to the same issue. Here is a detailed analysis: 1. Cause of carbon canister solenoid valve failure: When the vehicle is shifted into neutral, the engine should return to idle speed, and the carbon canister solenoid valve should close. If the solenoid valve fails to close or does not seal properly, gasoline vapors from the carbon canister will continuously flow into the intake manifold and then enter the combustion chamber, causing a sudden increase in engine speed in neutral. 2. Cause of vacuum sensor failure in the braking system: If the vacuum sensor malfunctions, it cannot detect whether the vacuum level in the power assist system is sufficient. In this case, the engine will increase its speed to enhance the intake vacuum, thereby raising the vacuum level in the intake manifold.
