What Causes the EBD Light to Illuminate?

There are multiple states in which the ABS light may illuminate, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly lit (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS control module from determining the vehicle speed and wheel slip rate, thereby failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the tone ring to restore normal function. Cause 2: Poor signal transmission due to loose system wiring connections or faulty ABS relay contacts, leading to system malfunction. Solution: Inspect wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple electrical components are in use, the battery voltage may drop below 10.5V. As engine speed increases and voltage rises, the ABS warning light turns off. This may also occur if the ABS system power supply voltage is too low, such as due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains lit after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding connection of the ABS hydraulic valve body; faulty wiring connector of the ABS hydraulic valve body; ABS control module malfunction. Solution: Loosen and retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check for enlarged connector gaps; replace the ABS or ABS/ASR control module. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS control module detects a significant discrepancy between rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact of the brake light. Solution: With the engine running, press the brake pedal and use a finger to push the brake switch linkage fully downward, then release the brake pedal to complete the self-setting process; replace the brake light switch if necessary. If the ABS warning light is illuminated, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.

At what age does an A2 driver's license automatically downgrade?

According to regulations, the age for downgrading an A2 driver's license is 60 years old, applicable to both men and women. Drivers should promptly visit the vehicle management office to exchange it for a C1 or C2 license, which permits driving small cars and small automatic transmission vehicles. Drivers are prohibited from operating large or medium-sized buses, trucks, tractors, or tram vehicles. Upon reaching 60 years of age, individuals generally enter the elderly stage, and their physical condition cannot compare to that of younger people. Although a small number of people may maintain good physical fitness after 60, traffic regulations cater to the majority. After 60, most people experience a decline in physical functions, such as deteriorating vision or conditions like hypertension and heart disease. Driving commercial vehicles under these circumstances can be hazardous, so drivers should comply with laws and regulations and promptly downgrade their license. The A2 license permits driving tractors, which can tow heavy or medium-sized full trailers or semi-trailers. Trailers are categorized into two types: full trailers and semi-trailers. A full trailer bears its total weight independently, while a semi-trailer shares part of its weight with the tractor. Only drivers holding an A2 license can operate such tractors; even those with an A1 license are not permitted to drive them. To downgrade an A2 license, visit the local vehicle management office with your ID card and driver's license. The downgrade will convert the A2 license to a B1 or B2 license. The A2 license corresponds to tractors, the B1 license to medium-sized buses, and the B2 license to large trucks. Other vehicle types that an A2 license holder can drive include: B1 (medium-sized buses), B2 (large trucks), C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled cars), and M (wheeled self-propelled machinery). Article 68 of the new traffic regulations states: If a driver holding a license for large buses, tractors, city buses, medium-sized buses, or large trucks falls under any of the following circumstances, the vehicle management office shall revoke their highest permitted driving qualification and notify the driver to complete the downgrade and license exchange within 30 days: 1. Being involved in a traffic accident resulting in death and bearing equal or greater responsibility, without constituting a crime. 2. Accumulating 12 penalty points in a single scoring cycle. 3. Failing to undergo inspection for three consecutive scoring cycles. A driver's license, officially known as a motor vehicle driving license or simply 'license,' is a document required by law for individuals operating motor vehicles. Driving a motor vehicle requires specific skills. Without these skills, operating a vehicle recklessly could lead to accidents. Generally, unlicensed individuals are not allowed to drive on roads. However, for those who have mastered safe driving techniques, the document permitting them to drive is the 'driver's license,' signifying it as a 'license permit.' The permission to drive is granted through the issuance of a driver's license, indicating that obtaining one is a formal process overseen by specialized authorities. Internationally, a driver's license is defined as 'a document issued by competent authorities permitting the holder to drive a motor vehicle.' In China, a driver's license is defined as: a legal certificate issued by management authorities to individuals who have learned and mastered traffic regulations and driving skills after passing required tests, permitting them to drive specific types of motor vehicles.

Why Does the Clutch Shake?

There are several reasons why the clutch shakes when starting: 1. The driven disc lining is broken, or the clutch compression spring is fractured, causing the clutch to vibrate. 2. Uneven pressure distribution on the car clutch, possibly due to loose or broken springs, or incorrect pressure positioning, leading to clutch instability. 3. The main drive disc is bent, or the clutch lever is caused by uneven separation lever heights. 4. Insufficient lubrication of the release sleeve and release fork shaft, resulting in clutch vibration. 5. The tension of the clutch compression spring is too high, causing the clutch to vibrate. 6. Clutch slippage or clutch disc burn-up.

Which button is for the trunk?

Car trunk switch button is located on the left side of the steering wheel. Here are the relevant introductions: 1. Remote key: The way to open the trunk from outside the car is through the remote key. This is also the most common way to open the trunk. Just press the car trunk icon (raised symbol) on the car key to activate the opening button and open the trunk. Some car models may not have a dedicated trunk opening button on the remote key, in which case simply pressing the unlock button will also open the trunk. 2. Control switch: The in-car control switches include button type and lever type. The position of button-type switches may vary depending on different manufacturers and car models, but generally they are located either on the left side of the steering wheel or in the central control area.
