What Causes Car Turn Signal Failure?

The reason for a car's turn signal staying on continuously is due to issues with the relay or wiring connections. The solution can be to replace the relay's fuse or check the connecting wires. The turn signal is a very important set of lights in a car, as it alerts surrounding vehicles and pedestrians, thereby enhancing driving safety. Below are the relevant instructions for using turn signals: 1. When driving to a flat intersection, depending on the width of the road, the flow of traffic, and the car's speed, turn on the turn signal at a distance of 15 to 30 meters from the intersection, neither too early nor too late. 2. At a roundabout, switch the direction of the turn signal promptly based on the car's direction of travel. 3. If you want to change lanes, first turn on the turn signal, then check the rearview mirror to see if the adjacent lane meets the conditions for changing lanes, and be mindful of oncoming traffic from behind.

What Causes the Car to Shake After Starting?

There are three main reasons why a car shakes after starting: 1. Low ignition energy: The first issue a car faces during a cold start is low temperature. The engine's internal temperature is insufficient, and both fuel and lubricant temperatures are low. Therefore, more fuel needs to be injected during a cold start to meet power requirements. The larger the spark plug gap, the lower the ignition energy. Poor fuel atomization at low temperatures requires higher ignition energy. Over time, the spark plug's ignition gap tends to widen, reducing ignition energy and affecting performance, causing the car to shake. 2. Carbon buildup on valves and intake passages: If carbon accumulates on the engine's valves and intake passages, it absorbs some fuel, leading to ECU miscalculations. For example, if the ECU controls the injection of 100 units of air-fuel mixture but only 90 units enter the cylinder, even complete combustion of these 90 units won't achieve the required power, resulting in shaking. 3. Incorrect air-fuel ratio: Inaccurate air-fuel mixture ratios can occur in both open-loop and closed-loop control systems. In closed-loop control vehicles, the oxygen sensor's minimum operating temperature is 370°C. If the exhaust pipe temperature doesn't reach 370°C upon starting, the oxygen sensor won't function. This causes the ECU to make errors in controlling the air-fuel mixture and ignition timing, reducing the car's power output and causing shaking.

What are the penalties for using an original driver's license?

After a driver replaces their driver's license, the original license becomes invalid and must not be used further. If a driver continues to use the original license in violation of regulations, the traffic management department of the public security authority will impose a fine and confiscate the original license. In cases where the original license was lost and later found after a replacement was issued, the driver must surrender the original license to the vehicle management office or destroy it themselves, and must not use both licenses simultaneously. Currently, each driver's license has a unique serial number and is managed with computer traceability. After a driver applies for a replacement license, the original license and its serial number will be marked as invalid in the driver's license management system. If the original license is later found and is still within its validity period, it must still be destroyed and cannot be used. If a driver's license is lost, there is no need to report the loss. The driver only needs to bring relevant documents to the vehicle management office to apply for a replacement. During the replacement process, a copy of the ID card will be required, along with a statement on the copy declaring the loss of the original license, to complete the replacement procedure. Additionally, it is important to note that when replacing a driver's license, the accumulated demerit points in the scoring cycle must not reach twelve. This ensures a smooth replacement process. If the replacement is due to damage to the original license, the original will be confiscated on the spot.

Are there any new regulations for driver's licenses in 2020?

There are new regulations for driver's licenses in 2020, specifically: 1. Self-registration is allowed. The nationwide Internet-based comprehensive traffic safety service management platform will be fully launched, enabling drivers to register online, schedule exams online, and make payments online through this platform; 2. Individuals with monocular vision can obtain a driver's license. Eligible individuals with monocular vision impairment can apply for a motor vehicle driver's license for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, and other permitted vehicle types; 3. Relaxation of physical conditions for upper limb disabled individuals to drive. Depending on the degree of finger, palm, or lower limb disability, they can apply for a motor vehicle driver's license for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, or small automatic transmission passenger cars specially designed for the disabled.

How to Extract Fuel from a Car?

To extract fuel from a car, follow these steps: 1. Prepare the necessary tools, including a flat-head or Phillips screwdriver, pliers, a plastic tube approximately 1cm in diameter, a wire, and a container for the gasoline; 2. Open the engine compartment hood and locate the fuel lines connecting the engine and the fuel tank. There are usually three lines: one supply line, one return line, and one carbon canister line. If the owner cannot distinguish between the three lines, all three can be disconnected, and the plastic tube can be connected to the gasoline container; 3. Next, open the vehicle's relay box, locate the fuel pump relay, remove it, and use the wire to short-circuit the 85 and 86 sockets on the relay socket. The relay box cover will have markings, making it easy to identify; 4. Insert the car key and turn it to the "ON" position. For vehicles with a push-button start, press the start button without pressing the brake pedal. Once activated, gasoline will flow out of the fuel line; 5. When the container has collected a sufficient amount of fuel, the owner can turn off the ignition, remove the short-circuit wire, reinsert the fuel pump relay, and finally reinstall the disconnected fuel lines to their original positions.

What are the precursors to a failing fuel pump?

Precursors to a failing fuel pump include: 1. Weak acceleration with jerking sensations when accelerating suddenly; 2. Difficulty starting the vehicle, requiring prolonged key turning; 3. Unusual buzzing noises while driving; 4. Illumination of the engine warning light; 5. Engine vibration or shaking. The primary causes of fuel pump failure are poor fuel quality, delayed refueling, and prolonged neglect of fuel filter replacement. Severe clogging of the fuel filter in the supply system forces the fuel pump to work harder, leading to damage due to prolonged high-load operation. It is recommended that drivers refuel promptly and choose reputable gas stations to ensure fuel quality and prevent damage to the fuel pump.
