Mercedes-Benz may fail to shut off due to the ignition switch EIS, but it could also be caused by an ESP module malfunction. Since each module's data in the vehicle relies on the vehicle's local area network communication, any issue with a module can lead to unusual symptoms, or even render the entire vehicle inoperable. It is recommended to use a diagnostic tool to check for fault codes and data. Open circuit in the wiring: For motorcycles with an AC ignition system, the vehicle is shut off by short-circuiting the ignition unit. Therefore, if the shut-off wire has an open circuit, the motorcycle cannot be turned off. Series connection in the wiring: This type of series connection is not a normal wiring setup but rather an abnormal cross-connection phenomenon. DC ignition systems are particularly prone to this type of fault. To troubleshoot, first determine if an anti-theft device is installed, then focus on inspecting the ignition switch connector and the wiring at the handlebar area. Occasionally, a damaged ignition switch can cause similar issues, though this is less common.

C2 Subject 2 Driving Test Items

The C2 Subject 2 driving test consists of four items: reverse parking into a garage, parallel parking, curve driving, and right-angle turns. Compared to the C1 manual transmission test, it excludes the hill start item. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), starting from June 1, 2021, the C2 and C5 Subject 2 tests no longer assess the hill start and stop. Reverse parking into a garage is one of the more challenging items in the Subject 2 test, so many test centers make it the first item. The key points for reverse parking are: the steering wheel's dead point, the 30 cm correction point, and the parking point inside the garage. The test taker must follow the prescribed route and sequence. The vehicle must be parked inside the garage without crossing the lines. Parallel parking focuses on aligning the front line of the garage with the rear wheel, spotting the rear corner in the side mirror, and the distance between the wheel and the left dotted line. The wheels do not need to be straightened after parking, and the turn signal must not be forgotten when exiting. After parking, the vehicle body must not cross the lines, and the tires must not touch the lane boundary lines during movement. Curve driving, commonly known as the S-curve, is manageable for many students with good driving sense, indicating its relatively low difficulty. However, some students misjudge the line positions during the actual test, leading to immediate failure by crossing the lines. The key to the S-curve is observing the position of the hood marker point relative to the boundary lines. The wheels must not press the road edges. Right-angle turns are even simpler, essentially a breakdown of the exit phase from reverse parking. The method for finding the reference point is the same as exiting the garage, focusing on the relationship between the hood's horizontal line and the front line (either aligning or delaying slightly). The wheels must not touch the road edges. Generally, the C1 Subject 2 requires 16 hours of training, while the C2 Subject 2 requires 14 hours. Completing the required hours is a basic requirement for taking the Subject 2 test. Training hours can only be increased, not reduced, and additional test items require corresponding extra hours. Each training hour is 60 minutes, with effective teaching time not less than 45 minutes. If a candidate fails the Subject 2 test, they can retake it once. If they fail again, the test is terminated, and the candidate must reschedule the test after ten days. If a candidate fails five consecutive test attempts (including retakes, totaling ten attempts), all previously passed subjects are voided, and the candidate must restart from Subject 1.

Where is the air conditioning filter in a van?

The location of the air conditioning filter in vans is generally the same, located inside the glove box on the passenger side. Open the upper part of the glove box door to find it. Functions of the air conditioning filter: 1. Filter moisture and harmful gases: It can absorb moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., preventing the car windows from fogging up, ensuring clear visibility for drivers and passengers, and avoiding the inhalation of harmful gases, thereby enhancing driving safety. 2. Filter solid impurities like pollen: It effectively separates dust, pollen, grinding particles, and other solid impurities from the air, maintaining clean air in the cabin without breeding bacteria, creating a healthy environment, and ensuring that drivers and passengers are not affected by allergic reactions, which could compromise driving safety.

What does PPT car manufacturing mean?

PPT car manufacturing refers to those car manufacturing companies that do not have a single mass-produced vehicle but create impressive PPT presentations to attract venture capital. Below is an introduction to related content: 1. Youxia Motors: As one of the new forces in car manufacturing, Youxia Motors is hailed as the "originator of PPT car manufacturing." The founder of Youxia Motors, Huang Xiuyuan, like Jia Yueting, loves to talk about dreams and disruption when managing the company. 2. Process: Both individuals' paths in car manufacturing have been quite bumpy. Jia Yueting, in his pursuit of car manufacturing, drained the cash flow of LeEco but still failed to achieve mass production. Coincidentally, Youxia Motors has also not achieved mass production to this day. 3. Business Operations: Huang Xiuyuan seems a bit like "armchair strategist." Skilled in talking about dreams, Huang Xiuyuan proclaimed Elon Musk as his idol and aspired to build his own career. With the support of his dreams, he secured substantial financing. With financial backing, Youxia Motors began developing its own cars. However, the first concept car they launched, the Youxia X, bore an uncanny resemblance to the Tesla Model S.

Under what circumstances can the emergency lane be used?

The emergency lane can be used in the following situations: 1. When a passenger in the vehicle suddenly falls ill; 2. When the vehicle experiences a sudden breakdown and cannot continue normal operation; 3. When driving an emergency service vehicle (such as an ambulance, rescue vehicle, or construction vehicle). The emergency lane on a highway refers to the part of the road adjacent to the right lane, including the hard shoulder, with a width of more than 3 meters and an effective length of 30 meters or more, which can accommodate the parking needs of motor vehicles. In emergency situations, vehicles can drive or park in the emergency lane. If the vehicle indeed encounters an unsolvable problem, it should be parked in the emergency stopping area, with the hazard warning lights turned on, and a warning sign placed 150 meters behind the vehicle.

Why is the dry dual-clutch transmission not good?

Dry dual-clutch transmission has the following disadvantages: 1. It has insufficient heat dissipation, making it unsuitable for frequent starts, prolonged low-speed driving, or stop-and-go traffic, which can lead to clutch overheating and even malfunctions; 2. Since it does not use a torque converter and cannot achieve the semi-engagement action of a manual transmission, for small-displacement engines, the dry dual-clutch transmission may exhibit insufficient torque at low speeds. Dual-clutch transmissions come in wet and dry types. A dry dual-clutch transmission refers to a dual-clutch transmission where the clutch plates are not immersed in transmission oil; in contrast, the clutch plates of a wet dual-clutch transmission are immersed in transmission oil.

How long does it take to drive 20 kilometers?

How long it takes to drive 20 kilometers depends on the driving speed. For example, at a speed of 40 kilometers per hour, it takes 30 minutes; at a speed of 80 kilometers per hour, it takes 15 minutes. The time required to drive 20 kilometers is also affected by road conditions. Driving on congested urban roads versus highways will result in different travel times. For vehicles on the road, the right side is farther from the driver, making it more prone to scratches than the left side. Therefore, drivers need to maintain a certain distance from surrounding vehicles to avoid scratches, which can also effectively save on car maintenance costs. When parking, drivers should leave enough space for other vehicles to prevent collisions, and avoid parking at intersections to prevent causing traffic congestion.
