Beijing BJ40 central control screen black screen reasons include aging wiring, prolonged usage, and circuit design defects. Aging wiring: This may be due to the aging of the power signal line of the Beijing BJ40 central control screen. You can try replacing it with a new signal line. If the black screen issue is resolved, it indicates a problem with the power signal line. Prolonged usage of the central control screen: When the Beijing BJ40 screen is used for an extended period, it can cause the power supply module to malfunction, leading not only to lag but also to a black screen in severe cases. Circuit design defects: It is necessary to go to a repair shop for inspection, repair, or direct replacement. When the Beijing BJ40 central control screen shows a black screen, you can first check whether it is caused by overheating protection due to the installation of additional devices. If the check is normal, it is recommended to take the vehicle to a professional repair facility for further inspection and handling.

What to do if the Mercedes-Benz GLA200 suddenly loses its reversing image?

There is usually a camera switch control in the display settings. Simply adjust the switch to "ON". Replace the reversing camera. The wiring harness for the reversing image runs from the dashboard all the way to the trunk, which is quite a long distance. It is likely that there is poor contact at some point in the wiring harness or connector, so a thorough inspection is necessary.

What does the nature of a car refer to?

Car nature is indicated on the vehicle's registration certificate and is categorized into commercial and non-commercial. Commercial vehicles generally refer to taxis, trucks, buses, etc., which can be used for transporting passengers or goods. Non-commercial vehicles refer to ordinary private cars, and if used for transporting goods, they may be penalized by traffic police. Below are the related introductions: Introduction to commercial motor vehicles: These refer to motor vehicles engaged in road transport activities for profit-making purposes, i.e., generating and obtaining economic benefits through transport activities related to business operations. Taxis, chartered minibuses, private large dump trucks, small trucks, buses, etc., all fall under commercial motor vehicles. Introduction to non-commercial motor vehicles: Non-commercial motor vehicles, as the name suggests, are not intended for profit-making purposes. Non-commercial motor vehicles are not allowed to participate in commercial activities; otherwise, they will be penalized. If participation in commercial activities is desired, the vehicle's nature must be changed by applying at the vehicle management office of the traffic management department of the public security organ where the vehicle is registered.

What is the emission standard for 2016 vehicles?

Vehicles from 2016 may comply with either the China IV or China V emission standards. The China V emission standard was implemented nationwide on January 1, 2017, but some cities adopted it earlier. Vehicle owners can identify the emission standard of their cars through the invoice, environmental label, and vehicle registration certificate. Below are the impacts brought by the China VI emission standard: 1. China IV vehicles may gradually become ineligible for registration, and China V new vehicles may depreciate faster: After the implementation of the China VI emission standard, China V and China IV vehicles will be affected. China IV vehicles may face restrictions such as being ineligible for registration or limited driving. After the introduction of China VI, the resale value of China V vehicles will decline, causing a significant impact on the used car market. The relocation restriction policy will ultimately lead to a drop in used car prices. 2. Increased vehicle purchase costs for consumers: As the China VI emission standard is stricter, automakers will upgrade components, leading to rising R&D costs and price increases, which will also raise the cost of purchasing vehicles for consumers. This is a factor consumers need to consider when buying a car. 3. Potential increase in vehicle usage costs: With stricter emission standards, fuel quality will also be upgraded, leading to higher fuel costs. Additionally, vehicle maintenance expenses may also change accordingly.

What to do if the wiper of Mercedes ML350 is not working?

Check if the wiper is stuck or disconnected. After confirming that the motor is functioning properly, proceed to inspect other potential issues besides the motor, such as whether the wiper circuit is broken. Check if the hardware is sufficiently lubricated. If none of the above issues are present, examine whether insufficient lubrication is causing excessive friction, preventing the spring from automatically resetting. If the wiper reset is obstructed, clean the wiper rubber and windshield with a damp cloth. Replace the wiper or rubber strip if necessary.
