The OBD interface in a car is similar to a power socket. Its function is to allow technicians to connect a computer to the OBD interface to access vehicle information and status. For example, if a vehicle generates a fault code, the maintenance personnel can simply connect a computer to the OBD interface to diagnose the issue and proceed with repairs. Another example is during the annual vehicle inspection, where the OBD interface is also required. Below is some relevant information: OBD, short for On-Board Diagnostics in English, means onboard self-diagnostic system in Chinese. As the name suggests, this function can diagnose the vehicle's status. By connecting to the OBD interface, real-time vehicle data can be viewed, and faults can be detected, providing convenience for vehicle repair, development of vehicle-related functions, and modification of vehicle equipment.

What Does Car Release of Lien Mean?

Car release of lien refers to the process of canceling the mortgage registration procedures for a mortgaged vehicle at the vehicle management office. After the release of lien, the car can be freely traded because, with a mortgage record, the vehicle cannot be freely traded or transferred. The reason a car is referred to as a mortgaged vehicle is that it has previously undergone mortgage registration at the vehicle management office, and the mortgage record is directly reflected on the motor vehicle registration certificate, which contains detailed mortgage information. Materials required for release of lien: Identity proofs of the vehicle owner and the mortgagee, the motor vehicle registration certificate. If the mortgage is to be released through court mediation, ruling, or judgment, the vehicle owner or mortgagee must fill out an application form and submit the motor vehicle registration certificate, the effective "Mediation Agreement," "Ruling," or "Judgment" issued by the court, along with the corresponding "Notice of Assistance in Execution." Release of lien process: Make an appointment for the service via an official account and receive a successful appointment SMS voucher. The mortgagor and mortgagee must bring all required materials together, show the successful appointment SMS, take a number at the service hall, and take a joint photo. The service is processed in order at the window, where the successful appointment SMS must be shown, and both the mortgagor and mortgagee must take a joint photo. Both parties can then collect the motor vehicle registration certificate at the designated window.

Can You Get License Plates Without Paying Vehicle Purchase Tax?

You cannot get license plates for a vehicle without paying the purchase tax. Article 14 of the Provisional Regulations on Vehicle Purchase Tax of the People's Republic of China stipulates that taxpayers must pay the vehicle purchase tax before registering the vehicle with the vehicle management authority of the public security organ. Taxpayers must present the tax payment certificate or tax exemption certificate issued by the competent tax authority to the vehicle management authority of the public security organ to complete the vehicle registration procedures. Without the tax payment certificate or tax exemption certificate, the vehicle management authority of the public security organ shall not process the vehicle registration. If the tax authority discovers that a taxpayer has failed to pay the vehicle purchase tax as required, it has the right to order the taxpayer to make the payment. If the taxpayer refuses to pay, the tax authority may notify the vehicle management authority of the public security organ to temporarily withhold the vehicle's license plates. The purchase tax is a tax levied by the tax authority on the acquisition of specified properties and assets within the scope of the purchase tax system, such as the vehicle purchase tax. The vehicle purchase tax is a tax imposed on entities and individuals who purchase specified vehicles within China, evolving from the vehicle purchase surcharge. The current basic regulations of the vehicle purchase tax law are the Provisional Regulations on Vehicle Purchase Tax of the People's Republic of China, implemented on January 1, 2001. Taxpayers of the vehicle purchase tax include entities and individuals who acquire taxable vehicles (through purchase, import, self-production, gift, award, or other means for personal use). The taxable scope includes cars, motorcycles, electric vehicles, trailers, and agricultural transport vehicles, with a tax rate of 10%.

What are car error codes?

Car fault codes are error codes reflected by the vehicle's computer ECU after a malfunction occurs. Generally, fault codes are caused by sensor malfunctions or poor sensor performance, but some mechanical faults cannot be read by the ECU. Examples of fault codes: P0107: Intake pressure sensor input voltage too low; P0108: Intake pressure sensor input voltage too high; P0109: Intake temperature sensor circuit malfunction or intermittent intake pressure sensor circuit; P0110: Intake temperature sensor circuit intermittent fault; P0111: Intake temperature sensor wiring malfunction; P0112: Intake temperature sensor circuit voltage too low; P0113: Intake temperature sensor circuit input voltage too high; P0114: Intake temperature sensor circuit intermittent fault; P0115: Engine coolant temperature sensor circuit malfunction; P0116: Engine coolant temperature sensor malfunction; P0117: Engine coolant temperature sensor voltage too low; P0118: Engine coolant temperature sensor voltage too high.

What are the precautions after a car has just been tinted?

Within three days after the car window tinting, do not wash the car as it may cause the film to peel off. After the tinting is completed, avoid rolling down the side windows for 24 hours in summer and 48-72 hours in winter, as doing so may cause the film to shift. If bubbles are found, they should be addressed within 24 hours at a professional car beauty and maintenance shop. Additionally, within one month after applying sunshade and heat insulation film, refrain from using strong adhesive labels directly on the film, as this may cause partial detachment from the glass. Before the tinting process, drivers should first protect the interior facilities by covering the seats and dashboard with plastic covers. During the tinting process, avoid using lubricants that may cause the film to fade, and do not apply the film under direct sunlight, as this may lead to wrinkles and bubbles, significantly affecting the car's appearance. The cleaning of the glass is the foundational work for the quality of the tinting. Generally, cleaning the glass involves three steps: inspecting the glass for damage and removing adhesive particles and sand; dusting and cleaning the glass (since water is needed for dust removal and lubrication, be careful to prevent water from leaking into the car's audio and electronic control systems, and it must be cleaned three times); and cleaning before applying the film, taking care not to damage the heating wires when cleaning the rear windshield.

How to Remove Stains from Car Paint?

Distributed near the four wheels of the car body, spray tar remover around the tar spots, let the cleaner soak for about a minute, and then wipe off the tar with a towel. For tree sap, adhesive, or sticker residue, use adhesive remover while spraying and wiping. Pour water or car wash liquid on the car's surface paint, and repeatedly scrub with car detailing clay. You will notice that the scrubbed area becomes smooth. Damaged and eroded by various harmful gases in the atmosphere, a hard and rough oxide film forms on the paint surface, causing the paint to gradually fade, harden, and lose its gloss.

What Are the Common Warning Lights in Cars?

Common warning lights in cars include the tire pressure warning light, coolant temperature warning light, and oil pressure warning light. Tire Pressure Warning Light: The symbol is a yellow irregular circle without a seal on top, with four small spikes at the bottom and an exclamation mark inside. The appearance of this symbol indicates abnormal tire pressure, and the tires need to be checked promptly. Coolant Temperature Warning Light: The symbol resembles a thermometer icon on the vehicle's computer panel. The coolant temperature warning light displays the temperature of the engine coolant, usually in red. If this light turns on, it means the engine temperature is too high, and the temperature gauge needle will also point to the red zone. This is a serious engine issue that can easily lead to engine seizure and other failures. Oil Pressure Warning Light: The symbol is a kettle-shaped icon on the dashboard. It lights up when oil pressure is abnormal. When the car starts, the oil pressure indicator will illuminate; if the oil pressure is normal, it will turn off later. If the oil pressure remains abnormal, the light will stay on.
