What is the reason why the anti-skid light stays on and cannot be turned off?

When the anti-skid light is on, it indicates that the ESP system is turned off or has malfunctioned. The reasons for the anti-skid system light to illuminate are as follows: 1. Accidentally pressing the ESP system's off button; 2. Loose or faulty sensor connectors; 3. Short circuit in the wiring or related fuse blown; 5. Software issues causing poor signal transmission; 6. ABS pump failure. Methods to turn off the anti-skid light: 1. Restart the engine and briefly press the ESP-OFF button on the vehicle to check if the anti-skid light was accidentally turned off; 2. Take the vehicle to a 4S shop for inspection, use a specialized fault diagnostic tool to locate the issue, and after repair, use a decoder to clear the fault code. Once the ESP system is confirmed to be working normally, the anti-skid light will turn off.

How to Determine When to Replace Spark Plugs?

The main signs that spark plugs need replacement are noticeably high fuel consumption and sluggish vehicle performance with unresponsive throttle. 1. Difficult starting. Whether cold or warm starts, it's nearly impossible to start the engine immediately - even successful starts take 5-6 seconds. This occurs because the spark plug electrodes are severely worn, with rounded edges around the center electrode, resulting in weak and unstable spark discharge. Additionally, excessive spark plug gap leads to insufficient spark intensity and weak penetration power, making it difficult to ignite the air-fuel mixture. 2. Increased fuel consumption. Normal consumption of 7-8 liters per 100km may suddenly jump to over 10 liters. The exhaust pipe emits not just fumes but practically spews money as refueling frequency increases. 3. Noticeable power loss during hill climbs or rapid acceleration. Especially when carrying passengers, the vehicle won't respond even with full throttle. This happens because deteriorating spark plug performance increases misfire rates, causing incomplete combustion of the air-fuel mixture and failure to achieve the engine's designed maximum power output. Spark plug replacement intervals: Under normal maintenance conditions, replacement is recommended at 40,000-60,000 km, though this varies by brand and engine type (consult your owner's manual). Reference these general standards: • Platinum spark plugs: replace at 40,000 km • Standard nickel alloy spark plugs: replace at 20,000 km • Iridium spark plugs: replace at 60,000-80,000 km

How to Use Rearview Mirrors When Reversing?

Method for using rearview mirrors when reversing: When reversing, pay attention to observing the left and right rearview mirrors. To adjust the left rearview mirror, position the horizon in the center, with the left and right positions adjusted so that the car body occupies one-fourth of the mirror's area. For the right rearview mirror, place the horizon in the upper two-thirds to allow more ground visibility, with the left and right positions the same as the left mirror. Control the vehicle speed when reversing and avoid pressing the accelerator if possible. Below are some precautions for reversing: 1. Always check for pedestrians or electric bikes behind you when reversing. Slow down to minimize danger in case of an accident. 2. When making a U-turn or reversing on a wider road, you can directly judge the position of the rear or wheels on the road through the rearview mirror. On narrower roads, if you cannot accurately determine the position of the rear and rear wheels from the mirror, open the door and observe the rear wheels while operating. When making a U-turn or reversing at intersections or street corners, expand the rear visibility and range, and be cautious of passing vehicles, pedestrians, and bicycles.

Is an ignition advance angle of 12 degrees or 9 degrees better?

An ignition advance angle of 9 degrees is better, for the following reasons: The ignition advance angle is generally between 6 and 12 degrees. A 12-degree ignition advance angle is too large compared to 9 degrees, which can lead to delayed ignition. If ignition is delayed, the gas will have difficulty performing work, fuel consumption will increase, efficiency will decrease, and exhaust noise will also increase, affecting the engine's working efficiency. Additional information: Ignition advance refers to the spark plug firing before the engine piston reaches the top dead center of compression. The angle through which the crankshaft rotates from the moment the spark plug fires until the piston reaches the top dead center of compression is called the ignition advance angle.

How Many Questions Are There in Subject 4 Exam?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," Subject 4 consists of 50 questions, each worth 2 points, totaling 100 points. Questions 1-10 are true/false; questions 11-40 are single-choice; and questions 41-50 are multiple-choice. The exam includes question types such as image analysis, animated case studies, and textual descriptions. The scope of Subject 4 covers driving knowledge under adverse weather and complex road conditions; identification of common traffic signs, markings, and hand signals; accident rescue and hazardous material handling knowledge; comprehensive judgment of violations and case analysis; emergency avoidance knowledge; safe driving knowledge; and driving ethics and civilized driving knowledge. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," there is no limit to the number of attempts for Subject 1 and Subject 4 exams. If the first attempt on the same day is unsuccessful, a retake can be conducted immediately. If it still fails, a new appointment is required, and no retake fee is charged. However, it should be noted that the validity period of the driving skill test permit is three years. If the applicant fails to complete the exam within the validity period, the passed subject scores will be invalidated. Subject 4, also known as the Subject 4 theory exam or driver theory exam, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and the addition of a safety and civilization knowledge exam, commonly referred to as "Subject 4." Subject 4 is the colloquial term for the Subject 3 safety and civilized driving knowledge exam and is not a separate subject. Since this exam is conducted after Subject 3, it is commonly referred to as the Subject 4 exam. Officially, there is no Subject 4. The safety and civilized driving knowledge exam is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 30 minutes, and incorrect answers totaling 12 points (6 questions) will terminate the exam. Number of Questions: Depending on the type of license being tested, 50 questions are proportionally selected from the corresponding Subject 4 question bank. Small vehicle licenses draw from 800 questions, while large vehicle licenses draw from 1,023 questions, with each question worth 2 points. Question Types: The questions include single-choice (including true/false) and multiple-choice. The first 45 questions are single-choice, and the last 5 are multiple-choice. The exam also includes animated questions, image-based questions, scenario recognition questions, and textual description questions. Retake Notes: If Subject 4 is not passed, only Subject 4 needs to be retaken. The driving school will schedule the retake, with no limit on the number of retakes. No retake fee is required for Subject 4. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the exam on road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills exam; and Subject 3 refers to the road driving skills and safety and civilized driving knowledge exam.
