What to Do When Several Warning Lights Come On After Vehicle Inspection?

Why is the AC still blowing hot air when the cold air is turned on?

Press the blue downward arrow button to lower the temperature. Specific explanations are as follows: 1. AC is the cold air switch: The AC button controls the air conditioning compressor. In summer when using air conditioning, you must press the AC button to activate the cold air. However, the warm air simply utilizes the internal heat circulation of the car and does not require the air conditioning compressor to be turned on. Therefore, to use warm air, you only need to adjust the air conditioning buttons without activating the AC switch. 2. Car air conditioning: The car air conditioning system is used to regulate and control the temperature, humidity, air cleanliness, and airflow within the car cabin to optimal conditions, providing passengers with a comfortable environment and reducing travel fatigue. It also creates good working conditions for the driver and plays an important role in ensuring safe driving. Generally, it includes a cooling device, heating device, and ventilation device. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally.

What is the installation method for a motorcycle throttle cable?

The installation method for a motorcycle throttle cable is as follows: 1. Pass the throttle cable through the carburetor upper cover, place the spring over the throttle cable, then extend the throttle cable through the throttle valve hole, pull it out from the adjacent slot and wind it all the way to the bottom, finally placing the head of the throttle cable into the groove at the bottom of the throttle valve; 2. When installing the throttle valve into the carburetor, ensure that the small beveled side of the throttle valve faces the idle screw, and the long groove aligns with the protruding point inside the carburetor before tightening the cover. Both cables on the motorcycle lead to the throttle grip on the right side of the handlebar. The top one is the throttle cable, responsible for controlling the throttle valve and needle valve, while the adjacent one is the accelerator pump cable, which allows the carburetor to inject a burst of fuel into the venturi during rapid throttle opening to enhance acceleration performance.

Does a 15-year-old vehicle require on-site inspection in 2021?

A 15-year-old vehicle needs to undergo on-site inspection after the annual inspection validity period expires in 2021. For new vehicles within 6 years, they are exempt from inspection twice. At the 6th and 8th years, the vehicle must undergo on-site inspection. For private cars over 10 years old, those between 10 and 15 years require annual inspection once a year, while those over 15 years require inspection every six months. The new regulations include non-operational mini and small passenger vehicles with 7 to 9 seats (excluding vans) within 6 years in the exemption scope. Here is additional information: Article 15 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states that motor vehicle safety technical inspections shall be conducted by motor vehicle safety technical inspection institutions. Motor vehicle safety technical inspection institutions shall inspect motor vehicles in accordance with national motor vehicle safety technical inspection standards and bear legal responsibility for the inspection results.

Is It Dangerous When the Low-Pressure Run-Flat Indicator Stops?

Low-pressure run-flat indicator stopping is dangerous. When the low-pressure run-flat indicator stops, it indicates that the air pressure in at least one tire deviates from the pressure recorded during the last reset. It is necessary to recheck the tire pressure and then reset it, as this serves as a reminder for tire pressure inspection. If the tire pressure is insufficient, the dashboard will reactivate the low-pressure run-flat indicator. First, check the air pressure values of all four tires. If the indicator persists after adjustments, you can locate the maintenance menu via the steering wheel and select the tire pressure recovery reset option. Tire pressure refers to the air pressure inside the tires, and there should be a standard tire pressure label on the rear of the driver's side door. The tire pressure measured approximately three hours after parking is considered relatively standard. Vehicles have relatively high requirements for tire pressure, which also varies with seasonal changes and the weight carried by the vehicle.

Does Driving in S Mode All the Time Damage the Engine?

Driving in S mode all the time can damage the engine. S mode is a sport mode, and when switched to S mode, the car's power increases directly, turning into an aggressive driving mode, which is different from the usual gear settings. Long-term use of S mode can accelerate the wear of high-speed rotating components inside the engine due to the more aggressive driving style in S mode. At the same time, the engine speed is increased in S mode, putting the engine under high load, and fuel consumption will be proportional to the power output. Although S mode has an impact on the engine, it also has positive aspects. For example, S mode makes the engine inject more fuel to maintain power output while driving. This process consumes more fuel, but the fuel acts as a cylinder cleaner. When excessive fuel is injected into the cylinder, it can clean the carbon deposits on the valves and inside the cylinder, making the power output smoother. Occasionally using S mode can still be beneficial to the engine to some extent.

How to Read an Automotive Wiring Diagram?

Being able to understand automotive wiring diagrams is fundamental knowledge for vehicle repair. Only by comprehending the wiring diagram can one grasp the characteristics and principles of automotive circuits, enabling the identification of fault causes in the shortest time when a vehicle malfunctions. The methods for reading are as follows: 1. Carefully read the diagram notes: Thoroughly review the diagram notes to understand the name and technical specifications of the wiring diagram, clarify the meanings of graphical symbols, and establish a one-to-one correspondence between components and graphical symbols. This will facilitate quick and accurate diagram interpretation. 2. Master the principle of circuits: In electrical theory, a circuit is the most basic, important, and simplest concept. Any complete circuit consists of a power source, electrical appliance, switch, wires, etc. For an electrical appliance to function properly, it must receive electrical energy. In a DC circuit, current always flows from the positive terminal of the power source, through wires, fuses, and switches to the electrical appliance, and then returns to the negative terminal of the same power source via wires (or grounding). If any part of this process is incorrect, the circuit will not function properly or effectively.
