What is the definition of an OBD interface?

Definition of OBD interface: OBD is the abbreviation of On-Board Diagnostic, which translates to "On-Board Diagnostic System". This system continuously monitors the operating conditions of the engine and the working status of the exhaust after-treatment system. Once it detects a situation that may cause excessive emissions, it will immediately issue a warning. The following are four functions of the OBD interface in vehicles: 1. Display of vehicle computer data: The OBD interface can provide various operational data of the vehicle, such as data displayed on the vehicle dashboard, fuel consumption records, battery voltage, air-fuel ratio, throttle opening, knock count, etc.; 2. Reading fault codes: The OBD interface can be used to read fault codes, which helps quickly diagnose vehicle faults and reduces the time required for manual diagnosis; 3. Changing codes to achieve more functions: By connecting the vehicle's CAN bus through the OBD interface data cable and adjusting the codes of various modules, many different "hidden" functions can be enabled, achieving "additional configurations"; 4. Reading and flashing ECU/TCU programs: This allows manufacturers to update the control programs of the ECU at any time, but it is not recommended to modify them yourself.

What are the precautions for novice drivers on the road?

Precautions for novice drivers on the road: 1. Be sure to affix the "Intern" sign at the rear of the car, which is usually obtained from the driving school you attended or the local vehicle management office; 2. Check the vehicle before driving, including whether the tire pressure is sufficient and the onboard tools are complete; 3. Frequently observe the rearview mirrors, as they allow you to monitor the road conditions on the left and right rear sides of the vehicle, especially when changing lanes, reversing, or overtaking, where the role of the rearview mirrors is crucial. Novice drivers should initially stick to familiar routes to develop a sense of the road and direction. Some drivers lose most of their sense of direction as soon as they sit in the cockpit, forgetting the pre-planned route and not knowing where to go. In such cases, pay more attention to distant traffic signs and find ways to return to familiar main roads. Remember, it's better to take a detour than to violate traffic rules.

Can Vehicles with Temporary License Plates Drive on Highways?

Whether vehicles with temporary license plates can drive on highways depends on the type of temporary plate. If it is a temporary license plate with "light blue background, black characters, and black borders," it is only for motor vehicles driving within the city. Temporary license plates with "brown-yellow background, black characters, and black borders" are for motor vehicles driving across cities. Temporary plates with "blue" background can be used on highways, but only within the city. Temporary license plates are paper motor vehicle license plates that allow temporary road use, also known as temporary driving license plates. They are temporary vehicle driving certificates issued by the vehicle management department of the public security bureau for newly purchased vehicles before formal registration.

Why does the dashcam battery not hold a charge?

The reason the dashcam battery does not hold a charge is that the built-in battery of the dashcam is very small, with a capacity of only a few hundred milliamperes. When the vehicle is parked and in detection mode, the built-in battery typically lasts only about 20 hours. Different brands of dashcams have varying battery capacities, and the battery life depends on the dashcam's battery capacity. There are two power supply methods for dashcams: one is powered through the cigarette lighter, where the dashcam uses its own lithium battery to record for a period after the vehicle is turned off before shutting down; the other method involves connecting the dashcam to the car battery and ACC power supply, where the battery provides power, and the ACC is only used for power detection—the dashcam stops working when the ACC is cut off. Some brand dashcams can be manually controlled, allowing the owner to shut off power based on recording time.

Why is the Leiling engine so noisy?

There are many reasons for the loud noise of the Leiling engine, such as engine parts wear, muffler aging, poor lubrication system, excessive carbon deposits, etc., which can all generate noise. By adding shock-absorbing plates and sound-absorbing pads, the road noise and tire noise of the engine can be effectively solved. The Leiling is a model under GAC Toyota Motor Co., Ltd., with body dimensions of 4640mm in length, 1780mm in width, and 1455mm in height, and a wheelbase of 2700mm. In terms of appearance, the Leiling adopts the North American version styling of the car series. The front face design has increased lines compared to the old model, with raised front fenders on both sides, and the headlights have been changed to a hook style. The overall rear styling has been slightly modified, with a black horizontal chrome strip running through the taillights on both sides, and the lower black surround wrapping around the rear, changing the previous purely family-oriented image.

What does the letter V on a tire mean?

Tire letter V indicates the speed rating of the tire, with V representing a maximum speed of 240 kilometers per hour. The alphanumeric characters on the tire represent in order: section width, aspect ratio, tire type code, rim diameter, load index, and speed rating. Taking 205/60R1691V as an example, 205 refers to the section width of the tire, which is the width between the two sidewalls; 60 is the aspect ratio, representing the ratio of the tire's section height to its section width; R stands for radial tire; the number 16 represents the rim diameter in inches; 91 indicates the load rating; and V denotes the maximum speed at which the tire can carry a specified load under defined conditions.
