What are the reasons for vehicle authentication failure and failure to start?

Engine authentication failure and failure to start may be due to a dead key battery, a malfunction in the one-touch start function, or faults in the body control module or circuit. It is recommended to contact the local 4S store for inspection and repair. The following are related content introductions: 1. Whether it is locked: Determine whether the anti-theft system is locked. Determine whether the starting system is working (whether the starter is running). 2. The starting system is normal: check whether the ignition system is normal; if the starting system is abnormal and turns slowly, check the battery voltage, whether the starter has a fault, and whether the engine has excessive resistance; if the starter does not run, check the starter circuit and electromagnetic switch. Check whether the fuel supply system is normal.

What is the passing score for Subject 2 under the new driving test regulations?

Subject 2 has a full score of 100 points, with assessment criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: ① For applicants of large buses, tractors, city buses, medium-sized buses, and large trucks, a score of 90 points is required; ② For other vehicle types, a score of 80 points is required. The test items for small vehicles C1 and C2 include reversing into a garage, parallel parking, stopping and starting on a slope (canceled for C2), turning at a right angle, and driving on a curve (commonly known as the S-curve), which are the five mandatory test items (some regions also include a sixth item: high-speed toll card collection). The test items for large vehicles A1, A2, A3, B1, and B2 include stake test, stopping and starting on a slope, parallel parking, passing a single-plank bridge, driving on a curve, turning at a right angle, passing a width-limited gate, passing continuous obstacles, driving on bumpy roads, making a U-turn on a narrow road, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling. For Subject 2, if the test is not passed on the first attempt, one retake is allowed. If the retake is not taken or still not passed, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of rescheduling for Subject 2 and Subject 3 road driving skill tests must not exceed five times. If the fifth rescheduled test is still not passed, the results of other subjects that have been passed will be invalidated.

What to Do If the Fuel Tank Under the Chassis is Scratched and Leaking?

If you find the fuel tank leaking, you can clean the leaking area and apply soap or chewing gum to temporarily seal the leak. When the fuel pipe is cracked, clean the cracked area, apply soap, wrap it with cloth or tape, and then apply another layer of soap. If the fuel pipe is broken, find a rubber or plastic tube with a similar diameter to the fuel pipe for connection. Secure both ends with wire. If the engine fuel pipe joint is leaking, wrap cotton yarn around the lower edge of the "horn" and tighten the fuel pipe nut and joint. Soften the soap with water, knead it into a putty-like consistency, and press it into the leaking area of the radiator. Filling the cooling fins can temporarily stop the leak.

What car does Nan Sun drive?

Nan Sun drives a BMW i3 pure electric vehicle. Advantages of the BMW i3 pure electric vehicle: The exterior has a high-tech feel, with the i3 featuring a suicide door design paired with retro-style suicide doors, making it much easier for rear-seat passengers to exit. Carbon fiber body – the BMW i3 is constructed entirely with a carbon fiber body. BMW has carbon fiber factories worldwide, requiring approximately 10 layers of carbon fiber to manufacture components used in the i3. Handling – the i3 continues BMW's tradition of excellent handling. Since the pure electric vehicle's battery is placed in the middle of the chassis, the overall weight distribution is relatively balanced compared to gasoline-powered cars, resulting in a solid chassis performance with strong controllability. Disadvantages: Comfort and interior configuration – the sense of cheapness is quite strong. The materials used for the front and rear door panels are very hard. The pure electric version comes standard with fabric seats, which are not as soft as those in BMW's sedan series. It still uses manual seat adjustment, and the cabin space, particularly the small rear windows, can feel somewhat oppressive. As a hatchback, the trunk space is also quite limited.

What Causes the Strong Jerking Sensation When Shifting from Second to Third Gear in an Automatic Transmission?

Introduction to the causes of a strong jerking sensation when shifting from second to third gear in an automatic transmission: Transmission issues: The jerking sensation during gear shifts in an automatic transmission can be caused by dirty transmission fluid, oil pump pressure leaks, or internal clutch slippage. A detailed analysis of the transmission's data stream is required to pinpoint the exact cause. Shift solenoid issues: If the vehicle has been in use for 2 years or has reached 60,000 kilometers, it may be necessary to replace the transmission fluid. If the problem persists after fluid replacement, the shift solenoids for second and third gears should be inspected. Engine oil passage blockage: The combustion of fuel, which is the source of the engine's power, is determined by the engine's ignition, air intake, and fuel injectors. If the air intake decreases, ignition weakens, or the fuel injection is reduced, the engine's power output will drop, leading to a jerking sensation.

Can You Drive with Low Tire Pressure in a New Car?

When the tire pressure is low, check the normal range for your vehicle's tires. If the tire pressure is within the normal range, you can drive; if it's below the normal range, you should not drive. Therefore, if the tire pressure is too low, it's best not to drive as it can cause significant harm to the vehicle. Low tire pressure in a new car may occur due to the following reasons: The car has been parked for too long, causing the tire pressure to decrease. When the car leaves the factory, the tire pressure is usually closer to the upper limit of the safe range. However, as the car remains parked for an extended period, the tire pressure gradually decreases. Some manufacturers intentionally lower the tire pressure to prevent excessively high speeds. Since it's a new car, even experienced drivers need an adaptation period. During this time, lowering the tire pressure slightly helps prevent traffic hazards caused by high speeds. Tire damage. Although rare in new cars, it's not impossible. The tire might have had issues at the factory or could have been punctured during use. If the low tire pressure warning appears in a new car, always check carefully for possible tire damage. Reasons for abnormal tire pressure: Generally, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. In such cases, inspect the tires and adjust the pressure accordingly. The tire pressure monitoring system hasn't been reset. After inflating the tires, if the system isn't reset promptly, it will continue to display the old data, causing the tire pressure warning light to stay on. Simply reset the tire pressure monitoring system to resolve this. Damaged tire pressure sensor. The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors the tire pressure. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light may illuminate. In such cases, the only solution is to replace the sensor with a new one.
