What Are the Causes of Transmission Noise?

Transmission noise causes: 1. Insufficient lubrication or excessively high viscosity of the lubricant leading to poor lubrication. In this case, the corresponding lubricant should be replaced; otherwise, it will accelerate transmission wear and shorten its service life. 2. Loose bolts on the transmission housing (end cover), where vibration during use causes the bolts to loosen. Regular inspections should be conducted. The transmission mainly refers to the vehicle's gearbox, which is divided into manual and automatic types. A manual transmission primarily consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque variation through hydraulic power transmission and gear combinations.

What does fault code C0061 mean?

C0061 fault code indicates a malfunction in the lateral acceleration sensor. Here is an introduction to the lateral acceleration sensor: 1. In the Electronic Stability Program (ESP), the lateral acceleration sensor is used to measure the vehicle's lateral acceleration. Lateral acceleration refers to a key parameter related to the centrifugal force generated when the vehicle is turning. 2. Vehicle lateral acceleration refers to the acceleration perpendicular to the driving direction, which is caused by centrifugal force during turning maneuvers. Essentially, it represents the tendency of the car to be "thrown outward." The greater this acceleration, the more likely the vehicle is to deviate from its intended path. 3. The measurement principle of the lateral acceleration sensor is based on a deflection-extended mass system with capacitive detectors. Voltage is supplied by the ESP control unit. During turns, the generated lateral acceleration causes the mass element to overcome the force of the elastic rod, moving from its neutral position to a position corresponding to the lateral acceleration value. 4. Acceleration refers to the rate of change in velocity. Acceleration does not equate to speed. The function of this sensor is to measure acceleration, transmit the signal to the ECU for analysis, and then the ECU sends signals to relevant actuators to adjust the vehicle's driving state.

What Does Suspension Fault Mean?

Suspension fault means that there is a malfunction in the vehicle's suspension system. Common causes of faults are as follows: 1. Wear of ball joints or loosening of ball joint screws: Fault description: When the vehicle encounters bumps, a "clunking" sound is heard from the chassis. Fault inspection: Lift the vehicle and gently shake the tires to check the gap size, or use a pry bar to check the gap and looseness of each ball joint. Solution: Tighten the bolts and replace the new connecting rod, connecting ball joint, etc. 2. Aging or damage of the control arm rubber buffer: Fault description: When the vehicle encounters bumps, a "clunking" sound is heard from the chassis. Fault inspection: Use a pry bar to check each buffer rubber for cracks or aging. Solution: Replace the new swing arm buffer rubber or the new swing arm assembly. 3. Oil leakage or damage of the shock absorber: Fault description: A "clunking" or "squeaking" sound is heard when encountering bumps. Fault inspection: Check the shock absorber for signs of oil leakage, press the four corners of the car by hand to check the body's bounce and any abnormal sounds. Solution: Replace the new shock absorber. 4. Abnormal noise from the top rubber or plane bearing: Fault description: There is a "thumping" noise when passing over speed bumps, and a "squeaking" sound when turning the steering wheel in place. Fault inspection: Listen for sounds when turning the steering wheel in place or when lifting the car and turning the steering wheel. Solution: Replace the new top rubber or plane bearing, or add lubricant. Some sounds are caused by loose screws on the shock absorber. 5. Abnormal noise from the stabilizer bar bushing: Fault description: There is a "clunking" or "creaking" noise when driving and braking. Fault inspection: Check both sides of the bushing for clean, worn areas, and some are not easily detectable, usually eliminated by replacement. Solution: Replace the new stabilizer bar bushing. 6. Loosening of connecting and fastening parts: Fault description: A "clunking" noise occurs when encountering bumps. Fault inspection: Use a pry bar to check for looseness in each part. Solution: Tighten the loose screws.

How to distinguish between the big V and small V of the Reiz?

You can distinguish them by the engine displacement of the car. The small V refers to the 3.0L displacement, while the big V refers to the 2.5L displacement. Here are the detailed explanations: 1. The big V and small V of the Reiz are mainly used to differentiate the engine displacement, with no significant differences in configuration. 2. The main differences in the Reiz model configurations are between the V and S versions. S is the standard version, while V is the luxury version. 3. However, the differences between the small V and S are minimal, and the small-wheel version of the Reiz can generally be referred to as either small V or S. 4. The big-wheel version is called the big V, which belongs to the mid-to-high configuration in terms of model specifications. 5. For example, the small V and S have basically the same configurations and both belong to the small-wheel version, but the small V includes additional features such as a sunroof, airbags, and heated seats compared to the S. 6. Compared to the big S, the big V adds features like a large roof lighting system, aluminum alloy accelerator pedals, 8-way electric adjustment for the front seats, and an automatic headlight cleaning device, elevating the interior configuration to a higher level.

How many chances are there for each subject of the driving test?

Subject 1 and Subject 4 are knowledge-based questions about civilized driving, and there is no limit to the number of attempts for these two subjects. Subject 2 and Subject 3 can only be taken a maximum of 5 times. If you fail to pass within 5 attempts, you will need to pay additional fees and start learning again from Subject 1. Below is an introduction to each subject: 1. Subject 1: During the test, there is one retake opportunity. If you fail twice in a row, it will be considered a failure for this test. 2. Subject 2: During the test, there is one retake opportunity. If you fail twice in a row, it will be considered a failure for this test. Subject 2 has five test attempts. If you fail five times in a row, you will need to pay additional fees and start learning again from Subject 1. 3. Subject 3: During the test, there is one retake opportunity. If you fail twice in a row, it will be considered a failure for this test. You can schedule the next test after 10 working days. Subject 3 has five test attempts. If you fail five times in a row, you will need to pay additional fees and start learning again from Subject 1 (the results of Subject 1 and Subject 2 will be invalidated). 4. Subject 4: During the test, there is one retake opportunity. If you fail twice in a row, it will be considered a failure for this test. No additional fees are required. After failing, you can schedule the next test on your own after 10 working days. There is also no limit to the number of attempts for Subject 4, but it is best to complete it as soon as possible.
