What Causes the Car Display Screen Not to Light Up?

Screen not lighting up is usually caused by poor line contact. Here are the specific details: 1. Timely inspection: Promptly check whether there is a loose connection in the wiring. A loose connection can cause the central control screen to go black; simply reconnecting the loose part properly can resolve the issue. It could also be due to aging of the power signal line. Try replacing it; if the black screen issue is resolved, it confirms that the power signal line was indeed the problem. 2. Power supply module failure: If the central control screen still doesn't light up, it may be due to prolonged use causing the power supply module to fail, leading not only to lag but also severe cases of black screen. This could indicate a circuit design flaw. Issues with module abnormalities and design flaws require inspection, repair, or direct replacement at a repair shop.

What does AAS failure mean?

AAS failure refers to issues with the wheel speed sensor or the sensor and connector becoming detached. Below is more relevant information: 1. Symptoms of AAS failure: (1) The display does not light up, and the fan does not rotate. (2) The hollow cathode lamp fails to light up. (3) There is spark discharge inside the hollow cathode lamp. 2. Solutions: (1) First, check if the fuse is loose or blown, then inspect whether the power cord is broken or has poor contact. Under normal conditions, the insulation resistance between the power input line and the casing should be greater than 20MΩ. (2) It may be that the lamp power supply is faulty or not connected, the lamp head wiring is broken, or there is poor contact between the lamp head and the socket. Check the lamp power supply, wiring, and related connectors separately. (3) This is due to oxides or impurities on the cathode surface of the lamp. Increase the lamp current to several tens of milliamperes until the spark discharge stops. If ineffective, replace the lamp.

Will the Land Rover Discovery Sport be extended?

Land Rover Discovery Sport will be extended, with the new model's length/wheelbase increased by 160mm compared to the previous Evoque. Below is additional information about the Land Rover Discovery: 1. Body design: Unlike the Range Rover family which fully adopts a floating roof design, the Discovery family features an inclined C-pillar that divides the body into two sections, complementing the design of the Discovery Sport. 2. Advantages: The vehicle's appearance is just right—not too flashy but very aesthetically pleasing. 2. C-pillar design: Makes the trunk appear very spacious. It also adds a well-balanced suspension system to the vehicle, providing excellent road vibration filtering. The suspension is neither too hard nor too soft, offering a resilient ride. 3. Disadvantages: The materials used in the center console are somewhat low-grade, and the overall design is slightly monotonous. The layout is visually appealing but overly simplistic. If the silver trim on the center console could be extended and widened, it would enhance the sense of luxury.

What is the service life of commercial vehicles?

Commercial vehicles have the following service life: Small and micro rental passenger vehicles have a service life of 8 years, medium rental passenger vehicles have a service life of 10 years, and large rental passenger vehicles have a service life of 12 years; Public transport passenger vehicles have a service life of 13 years, other small and micro commercial passenger vehicles have a service life of 10 years, and large and medium commercial passenger vehicles have a service life of 15 years; Micro commercial trucks have a service life of 8 years, light and large commercial trucks have a service life of 10 years. Motor vehicle scrapping process: The owner of the vehicle applying for scrapping and renewal must fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form" in duplicate and stamp the owner's seal. Apply at the registration and acceptance counter, and for vehicles that have reached the service life, issue a "Vehicle Scrapping Notice". For motor vehicles that have not reached the service life, after inspection and confirmation by the motor vehicle inspection counter, if they meet the scrapping standards, issue a "Vehicle Scrapping Notice". The vehicle owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The vehicle owner must submit the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection counter for verification and signature. The license plates and certificates will be reclaimed, and the application will be submitted for approval according to regulations to complete the scrapping registration.

What is the difference between a 9-seater blue license plate and a 9-seater yellow license plate?

The differences between a 9-seater blue license plate and a 9-seater yellow license plate are as follows: 1. Applicable vehicle types: Blue license plates are for small vehicles, while yellow license plates are for medium and large passenger and cargo vehicles. 2. Driver's license: A Class C driver's license is sufficient to drive a blue license plate vehicle, while a Class B driver's license is required for a yellow license plate vehicle. 3. Highway tolls: Due to their larger size and weight, yellow license plate vehicles generally incur higher tolls than blue license plate vehicles. 4. Traffic restrictions: Yellow license plate vehicles are usually subject to time-based traffic restrictions in urban areas and may require a special permit, while blue license plate vehicles are generally exempt from such restrictions. 5. Annual inspection: Yellow license plate vehicles typically require an operation permit and must undergo an annual inspection, whereas blue license plate vehicles can be inspected every two years. 6. Operation permit: Blue license plate vehicles generally do not need an operation permit unless there is an operational requirement, while yellow license plate vehicles must obtain one; otherwise, they cannot be driven on the road.

What is the self-weight of a 9.6-meter high-barrier truck?

The self-weight of a 9.6-meter high-barrier truck is approximately 6-8 tons. Here is more relevant information: 1. 9.6-meter single-axle box truck: The chassis height of a 9.6-meter single-axle box truck is generally around 1.3-1.5 meters. The internal width of the cargo compartment is about 2.3-2.4 meters. The internal loading height is approximately 2.5-2.7 meters. The cargo compartment can hold about 50-55 cubic meters of goods (based on experience, the smaller the volume of the goods, the more actual cargo can be loaded. If the goods are bulkier, there will be more wasted space). 2. Notes: 9.6-meter single-axle box trucks are not very suitable for transporting large equipment because loading and unloading operations are difficult, and the goods are not easy to secure during transportation. The load capacity of a 9.6-meter single-axle box truck is generally within 0-12 tons.
