What is the inspection process for used cars?

Used car inspection can be divided into four major steps: vehicle documentation check; accident assessment; vehicle condition inspection; and vehicle condition rating. Below is a general introduction to the used car inspection process: 1. Vehicle documentation check. The appraiser first needs to verify the seller's ID, original purchase invoice or last transfer invoice, vehicle registration certificate, vehicle license, and other relevant documents to determine if the seller is the original owner. If not, the appraiser checks whether the seller is an agent or a dealer. This step ensures strict screening of vehicles to prevent the inflow of illegally sourced cars. 2. Vehicle accident assessment. The appraiser conducts an accident assessment on the used car to determine if the vehicle has been involved in any accidents and rates it according to the assessment standards. The rating standards are: A: Like-new condition with no scratches, B: Repainted body parts, C: Minor accidents that do not affect driving safety, D: Structural damage to the body, etc., divided into four levels. 3. Vehicle condition inspection. After the accident inspection, the appraiser also needs to conduct a detailed examination of the vehicle's specific condition based on industry-standard evaluation procedures. The main areas to inspect include the body, cabin, startup test, engine compartment, and auxiliary equipment. The appraiser performs over a hundred professional checks on these five parts and records the specific condition in detail. 4. Vehicle condition rating. The appraiser refers to the 'Used Car Inspection and Evaluation Technical Specifications' issued by the China Automobile Dealers Association and combines it with years of accumulated customer concerns. The rating is based on a combination of accident level and comprehensive scoring (the scoring levels are: 40 for poor overall condition, 60 for average overall condition, and 80 for excellent overall condition).

What's the reason for the navigation screen being black but the buttons making sounds?

If the screen is black but the sound is normal, try switching to a familiar interface and tap the touchscreen to see if it responds. If the touch function works normally, then the issue may lie with the display screen. More details are as follows: 1. Potential issues with the display screen include: LCD screen damage, abnormal LCD backlight driver, malfunction in the signal circuit, display decoding issues, or problems with the core module. 2. If the touchscreen is not functioning properly, the first suspicion should be a damaged touchscreen, which can be replaced. 3. Then, check the touch circuit. If the wiring is confirmed to be intact, the issue may be with the decoding chip or core module not working or being damaged.

How to Deal with High Resistance in Car Airbags?

Methods for handling high resistance in car airbags: 1. Check for open circuits. When poor connection of the wiring harness causes an open circuit, the system will indicate excessively high resistance; 2. Use a computer to read and determine which airbag has excessive resistance, then inspect the corresponding wiring harness connector for looseness; 3. If the airbag connector is in good condition without any obstruction, the issue lies within the main airbag, requiring inspection and repair; 4. Check whether the wiring beneath the airbag is properly connected to determine if the airbag clock spring is damaged; 5. If the airbag resistance is too high and the cause cannot be identified, it may be necessary to add a resistor or directly replace the airbag with a new one.

What to Do When the Coolant Boils Over?

Here are the steps to handle a coolant boil-over situation: 1. Pull over to the side of the road and let the engine idle for a while to allow the temperature to gradually decrease. 2. If the boil-over is caused by insufficient coolant, replenish it promptly after the engine temperature has dropped. 3. In case no coolant is available, as a last resort, you can add a small amount of water and proceed to the nearest repair shop for a replacement. Below are the reasons for coolant boil-over: 1. The radiator stops functioning, leading to excessively high water temperature. 2. The coolant is not circulating, either because the thermostat fails to open or the water pump is not working properly, resulting in a blocked water circulation system and causing boil-over. 3. Insufficient coolant. Low coolant levels can easily lead to boil-over. 4. Poor-quality coolant with a low boiling point is prone to boil-over.

Will a Gasoline Smell in the Car Cause an Explosion?

A gasoline smell in the car does not necessarily mean an explosion will occur, but if the smell is due to a ruptured fuel line causing a leak, the consequences can be very severe. If exposed to an open flame, there is a risk of explosion. Below are the reasons for a gasoline smell inside the car: 1. Ruptured fuel line in the engine compartment: In this case, as the vehicle moves, the leaking gasoline odor can enter the cabin through the gaps between the engine and the passenger compartment. This situation is extremely dangerous and could potentially lead to a fire, requiring high vigilance. The driver should immediately pull over, turn off the ignition and all electrical systems, and carefully inspect the issue or seek professional help to address the fuel leak. 2. Damaged fuel tank cap seal: If the seal on the small upper cap of the fuel tank is cracked or damaged, gasoline fumes may escape. Typically, the fuel tank is located under the rear seats of the car. There is a small round cap for maintenance and installation of the fuel pump and fuel gauge sensor, secured by several small bolts. If this cap or its seal is damaged, a strong gasoline smell can quickly permeate the cabin. 3. Faulty charcoal canister or damaged connecting pipes: The charcoal canister, unfamiliar to many, is an environmental device that absorbs gasoline vapors from the top of the fuel tank. It contains porous activated carbon, which strongly absorbs these vapors to dilute them when the fuel tank cap is opened during refueling, reducing environmental pollution. When the pressure of the absorbed gasoline vapors in the canister rises, its control valve opens, directing the vapors into the engine for combustion without polluting the environment. If the air pipe below the fuel tank's charcoal canister is blocked or the upper control valve is damaged, a gasoline smell may enter the cabin when the car is parked.
