When an exclamation mark appears on the car dashboard, there are 5 possible scenarios: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, or lighting system fault. Below is a detailed analysis of these 5 situations: General Malfunction: An exclamation mark inside a triangle indicates a malfunction in the vehicle's general performance, components, or functions. Common causes include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Failure: A yellow gear with an exclamation mark is the automatic transmission warning light, indicating a transmission fault or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Failure: An exclamation mark inside a circle with parentheses represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line below parentheses indicates the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible. Alternatively, you can inspect the vehicle yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

What procedures are required for vehicle scrapping?

Vehicle scrapping process: The owner of the vehicle applying for scrapping and renewal must fill out and submit one copy of the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form" with the owner's seal affixed. Apply at the registration and acceptance counter. For vehicles that have reached the scrapping age limit, a "Vehicle Scrapping Notice" will be issued. For vehicles that have not reached the scrapping age limit, if they are confirmed by the motor vehicle inspection counter to meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The vehicle owner should choose a qualified recycling company to dismantle the vehicle with the "Notice". After verifying the "Notice", the recycling company will dismantle the vehicle and take photos. The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The vehicle owner should 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.

What Causes Abnormal Noise in the Transmission Case of a Scooter?

Abnormal noise in the transmission case of a scooter may be caused by damage to rotating gears, bearings, etc. The reasons for abnormal noise in the transmission case of a scooter are as follows: 1. Relationship between abnormal noise and engine speed: Most common abnormal noises depend on the engine speed state. 2. Relationship between abnormal noise and load: Many abnormal noises in the engine are clearly related to its load. During diagnosis, the method of gradually removing the load can be used for testing, usually by using single-cylinder or dual-cylinder misfire to remove the load of one or two cylinders to identify the relationship between abnormal noise and load. 3. Relationship between abnormal noise and temperature: Noise occurs at low temperatures and diminishes or even disappears as the temperature rises. 4. Relationship between abnormal noise and the engine working cycle: Abnormal noise faults in the engine are often clearly related to the engine working cycle, especially the abnormal noise of the crankshaft connecting rod mechanism and the valve mechanism, which are related to the working cycle. 5. Relationship between abnormal noise and the engine location: When abnormal noise occurs in the engine, it will produce a certain degree of vibration. The characteristics and location of the vibration can assist in diagnosing the cause of the abnormal noise.

Is the Safe and Civilized Knowledge Test Subject 4?

Subject 3 Safe and Civilized Driving Knowledge Test is commonly referred to as Subject 4. Subject 4, also known as the Subject 4 Theory Test or Driver Theory Test, is part of the motor vehicle driver's license assessment. It mainly includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. The Subject 4 test consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing score of 90. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: the road test and the addition of the Safe and Civilized Knowledge Test, commonly known as "Subject 4," which assesses "driving ethics." Because this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test. Officially, there is no Subject 4. Before the test, students can study traffic regulations through driver simulation test software on mobile or computer devices.

What Causes Car Body Shaking?

Car body shaking can be caused by: 1. Mismatch between vehicle speed and gear; 2. Uneven tire pressure; 3. Severe wear of the drive shaft; 4. Dirty throttle or old spark plugs; 5. Deformed front wheel rims or unequal number of tire bolts; 6. Loose installation of transmission system components; 7. Bent drive shaft or deformed front axle; 8. Failed shock absorbers, inconsistent stiffness of front leaf springs, or deformed frame. The main functions of a car body are to protect the driver and create good aerodynamic conditions. A well-designed body not only enhances performance but also reflects the owner's personality. In terms of structure, car bodies are mainly divided into two types: body-on-frame and unibody.
