When the car malfunction indicator light comes on, it indicates that there may be a mechanical issue with the engine, and you should immediately take the vehicle to a 4S shop for repair. Here are the reasons why the car malfunction indicator light may illuminate: Starting system malfunction preventing the engine from turning or turning too slowly: Insufficient battery charge, loose or severely oxidized battery terminal clamps, blown main circuit fuse, or faulty ignition switch. Ignition system malfunction: Poor performance of the ignition coil, resulting in weak or no high-voltage spark. Fuel injection system malfunction: Empty fuel tank, non-operational fuel pump or low pump pressure, leaking or deformed fuel lines, or disconnected circuit relay. Intake system malfunction: Faulty idle control valve or its control circuit, cracked idle control valve air pipe or leaking connections, or malfunctioning air flow meter.

Last time I was driving, that warning light suddenly came on, and my heart skipped a beat. I quickly pulled over to a safe spot by the roadside. This kind of light usually means the car's computer has detected an issue with some part of the vehicle, possibly the engine emission system or a sensor. At the time, I first checked the status of other indicator lights on the dashboard—the car wasn’t shaking or making strange noises—so I drove slowly to a repair shop near home. The mechanic used a diagnostic tool and found it was just a dirty oxygen sensor; cleaning it fixed the problem. It’s important to develop the habit of scanning the dashboard for any abnormal lights before starting the car. If you notice an issue, don’t push through and drive on the highway—call for a tow truck if needed, and don’t hesitate over the cost.

What is the difference between deposit and earnest money in a car purchase contract?

Below are the differences between deposit and earnest money in a car purchase contract: 1. Different definitions: The earnest money in a car purchase contract is a certain amount of money paid as a guarantee when the car purchase contract is concluded or before performance. There is no clear legal provision for the deposit, which is generally regarded as an advance payment in the car purchase contract. This guarantee is unilateral, and it only binds the payer, that is, the payer's guarantee to the recipient. 2. Different guarantee effects: The biggest difference between earnest money and deposit is that earnest money has a guarantee effect, while deposit does not (even if it does, it is only the payer's unilateral guarantee to the recipient). Therefore, when such a car purchase dispute arises, the 4S store has the right not to return the earnest money previously paid by the consumer; if it was a deposit that was previously paid, except for deducting part of the liquidated damages, the consumer can recover part of the deposit.

Are Pickup Trucks Considered Commercial Vehicles?

Pickup trucks are considered commercial vehicles. Here is an introduction to pickup trucks: 1. Types of pickup trucks: Pickup trucks are a hybrid of passenger cars and commercial vehicles, belonging to the category of dual-purpose vehicles for both passengers and cargo. Pickup trucks feature a car-like front end and cabin, along with an open cargo bed. 2. Characteristics of pickup trucks: Pickup trucks combine the comfort of a passenger car with powerful performance, and they surpass passenger cars in cargo capacity and adaptability to rough road conditions. The most common type of pickup truck is the double-cab model. Pickup trucks can serve as special-purpose vehicles, multi-purpose vehicles, official vehicles, business vehicles, or family cars, used for cargo transport, tourism, rentals, and more.

What to Do When the Tire Pressure Monitoring System Shows Left and Right Reversed?

Tire pressure monitoring shows left and right reversed. The owner can readjust the tire pressure sensors and reinstall them in the correct left and right positions. If reinstallation is not preferred, a rematch can be performed. There are three common types of tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically issue an alert. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a higher rotational speed compared to the other wheels. By comparing the differences in rotational speeds between the tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS): This system combines the advantages of the two aforementioned systems. It is equipped with direct sensors in two diagonally opposite tires and a four-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.

Can 12 points be deducted using two driver's licenses at once?

No, 12 points cannot be deducted using two driver's licenses at once. Here is an introduction about driver's license point deductions: 1. Actions after point deduction: If the accumulated points reach 12 within a scoring cycle, the traffic management department of the public security authority should confiscate the driver's motor vehicle license. The driver must attend a seven-day road traffic safety-related knowledge training session at the traffic management department of the public security authority where the motor vehicle license was issued or where the violation occurred within fifteen days. After completing the training, the vehicle management office should conduct a knowledge test within twenty days. If the test is passed, the points will be cleared, and the motor vehicle license will be returned. Refusal to attend the training or take the test will result in the traffic management department of the public security authority announcing the suspension of the motor vehicle license. 2. Other violation point deductions: If the total of two traffic violations accumulates to 12 points, and the two speeding violations were committed by different drivers, the points can be deducted from the licenses of both drivers. If the two traffic violations accumulate to 12 points but were committed by one driver, the points can only be deducted from one driver's license.

What are the inconveniences of having an out-of-town license plate?

There are inconveniences such as annual inspections for out-of-town license plates. Below is an introduction to the inconveniences of having an out-of-town license plate: 1. Insurance processing: (1) The first drawback is the hassle with claims. Although insurance companies promise nationwide claims, there is a competitive relationship between two branches, which may lead to delays or reluctance in processing claims. (2) The second drawback is the trouble with paying vehicle and vessel tax. Out-of-town insurance companies cannot act as agents for collecting vehicle and vessel tax; it must be paid locally. 2. Replacing annual inspections, etc.: If the vehicle license or plate is lost, it can only be replaced at the vehicle's registration location. A vehicle missing its license plate does not have the legal right to be on the road, and driving without it may result in penalties such as a 12-point deduction. Therefore, it is necessary to promptly go to the out-of-town location to replace it. Regarding annual inspections, they are more troublesome since getting an inspection done out-of-town is not as convenient as doing it locally. For out-of-town license plates, during the annual inspection, one must first go to the vehicle's registration location to handle the power of attorney and other related procedures before conducting the annual inspection locally.

What is the difference between OEM wheels and aftermarket wheels?

The differences between OEM wheels and aftermarket wheels lie in price, craftsmanship, and quality. Below is the relevant introduction: 1. Definition of wheels: The wheel hub (Car-Rim) is the central part of the wheel where the axle is installed, commonly referred to as the "rim" or "steel rim." Wheel hubs are prone to accumulating dirt, and if not cleaned for a long time, they may corrode and deform, posing safety hazards. Therefore, special attention should be paid to the maintenance of wheel hubs. 2. Alloy material wheels: Alloy material wheels are lighter in weight, have smaller inertial resistance, and are made with high precision. They deform less when rotating at high speeds, have smaller inertial resistance, and are beneficial for improving the straight-line driving performance of the car.
