What does UDS mean in automotive?

UDS protocol is a unified diagnostic service, serving as a standard reference protocol for diagnostic services. For example, it specifies what commands should be sent to the ECU to read fault codes or data streams. It is a set of diagnostic protocols used to analyze current automotive issues, and this protocol is widely used in automotive electronics today. Below is relevant content introduction: Types: UDS is essentially a series of services, comprising 6 major categories with 26 types in total. Each service has its own unique ID, known as SID. SID: Service Identifier, diagnostic service ID. UDS is fundamentally a directed communication, an interactive protocol (Request/Response), meaning the diagnostic tool sends specified request data (Request) to the ECU, which must include the SID in this data.

Does registering with Didi make a vehicle an operational one?

No, it has nothing to do with registering on platforms like Didi. To change the usage nature of a personal vehicle (from non-operational to operational), one must first undergo training and obtain a ride-hailing driver's license, then purchase operational vehicle insurance from an insurance company (which is twice the cost of regular private car insurance), and finally apply for the change at the vehicle management office. After the change, the vehicle must be mandatorily scrapped after 15 years, with an operational period of 8 years. Below are the requirements for registering with Didi: 1. Male drivers must be at least 22 years old and no older than 60, while female drivers must be at least 22 years old and no older than 55. 2. A minimum of a C2 or higher class motor vehicle driver's license is required, with a driving experience of over three years. 3. A locally licensed vehicle that matches the driver's license class is required. It doesn't matter if the vehicle is not registered under the driver's name, but the vehicle must be less than six years old and have not exceeded 100,000 kilometers in mileage. 4. No bad records, no history of hit-and-run traffic incidents, and the registrant must not have been responsible for any major traffic accidents in the past three years or have accumulated 12 penalty points for traffic violations within the past year.

What types of motion does a car have during movement?

The motion of a car includes both rotational motion and translational motion. Here are the relevant explanations: Rotational motion: An object moves in a circular path around a point or an axis, such as the Earth rotating on its axis while also revolving around the Sun. This corresponds to the rotation of a vehicle's wheels. Translational motion: Within the same plane, when all points of a figure move the same distance in a straight-line direction, this type of figure movement is called translational motion, or simply translation. This corresponds to the physical phenomenon of a vehicle's body moving forward.

What are the symptoms of a flooded car engine after repair?

If the vehicle has only been soaked and then towed to a repair shop, this generally does not cause irreversible damage to the engine. The main task is to clean the accumulated water inside the engine, but the extent of cleaning depends on the situation. More often, the intake pipe and intake manifold are removed, and compressed air is used to dry the water inside. In such cases, there are usually no significant aftereffects. Below are other scenarios of engine water ingress: A small amount of water entering the cylinder: In many cases, the owner may not even realize that the engine has taken in water, and the amount of water is minimal. If the owner chooses to continue driving at this point, the ultimate consequence could be the piston seizing in the cylinder, with the connecting rod bending or breaking due to the immense pressure. In more severe cases, the broken connecting rod might even puncture the engine block.

How Many Days Are Three Inspection Cycles?

Vehicle annual inspection cycles are conducted according to regulations, with each annual inspection counting as one cycle. Three annual inspection cycles refer to the period during which three inspections are required. Below are the relevant details about annual inspections: 1. Inspection Cycle: The Road Traffic Safety Law and its implementation regulations set different inspection cycles based on vehicle purpose, type, age, and other characteristics. For small cars and blue-license minivans, within the first six years after registration, inspections are required every two years; after six years, inspections are annual; after fifteen years, inspections are required twice a year. For trucks, inspections are annual after registration, and after ten years, inspections are required twice a year. The documents required for vehicle annual inspections include: the vehicle's registration certificate, valid compulsory insurance policy, and vehicle and vessel tax receipt. 2. Initial Inspection: The inspection conducted to apply for a vehicle license is called the initial inspection. The purpose of the initial inspection is to verify whether the vehicle meets the conditions for license application. The inspection includes: 1. Checking if the vehicle has a user manual, certificate of conformity (for imported vehicles, the commodity inspection certificate), and whether the factory markings on the vehicle body are complete. 2. Measuring the vehicle's external and internal dimensions, wheelbase, and axle track. Specific measurements include vehicle length, width, height, cargo compartment height and area, wheelbase, and axle track. 3. Conducting inspections item by item according to technical standards. Upon passing, the "Initial Vehicle Inspection and Modification Registration Form" is filled out, including the vehicle's curb weight, load capacity, passenger capacity, and driver's compartment seating capacity as per the manufacturer's specifications.

What Could Be the Reason for a Pure Electric Vehicle Failing to Start?

Possible reasons for a pure electric vehicle failing to start include: Carbon buildup: Difficulty in ignition caused by carbon buildup in the car, accompanied by slight shaking at idle. Cleaning the throttle valve, intake tract carbon deposits, and fuel injectors can solve the problem. Weak energy: Weak ignition energy from the spark plugs can lead to decreased spark plug ignition energy, causing misfires in severe cases. Many current vehicle models feature direct-injection engines, which place higher demands on spark plugs. Low pressure: Insufficient low pressure in the fuel system can directly cause the engine to require a second ignition. The specific reason is that the first ignition attempt fails because the low-pressure fuel system is building up fuel pressure, while the second attempt succeeds. Components to check specifically: fuel pressure regulator, fuel pump, fuel filter, and fuel lines. Battery depletion: Battery depletion is a more common issue. When the car fails to start, the first reaction of many owners is that the battery is dead. The solution is also simple: just jump-start the car using another vehicle or battery.
