How long should you practice for Subject 3 before taking the test?

Subject 3 The duration of practice required for Subject 3 depends on individual aptitude. However, since the operations in Subject 3 are relatively simple overall, instructors typically arrange practice sessions only 3 to 4 days before the test. If your aptitude is not strong, be sure to communicate with your instructor in advance to start practicing earlier and secure more practice days. Subject 3 generally refers to the road driving skills test, while the safety and civilized driving knowledge test is referred to as Subject 4. The road driving skills test includes 16 items: vehicle preparation, starting, driving in a straight line, shifting gears, turning left at intersections, turning right at intersections, changing lanes, passing through intersections, pulling over, crossing pedestrian crosswalks, passing through school zones, passing through bus stops, meeting other vehicles, overtaking, making U-turns, and nighttime driving. For the Subject 3 road driving skills test, you have five opportunities to schedule the test. After scheduling, you can take the test once and have one retake, totaling ten attempts. If you do not attend the retake or fail the retake, you must reschedule the test. If you fail the fifth scheduled test, any previously passed subjects will be invalidated, and the student will need to retake the test starting from Subject 1.

Why Hasn't the New Electric Car Battery Been Fully Charged After Eight Hours?

New electric car battery hasn't been fully charged after eight hours due to poor fuse contact. Here is an introduction to battery charging voltage and current: 1. Voltage: The car charging voltage is 12V. During the charging process, the charging voltage is mostly between 13.5-14.5V. When charged on the vehicle by the rectifier, it won't exceed 15V. If using a charger, the charging voltage is generally 14V. 2. Current: During the car charging process, the charging current should not be too large. It is recommended that car owners avoid using fast charging. When charging, use half of the rated charging current and extend the rated charging time by double.

What is the reason for the EPC light on the Jianghuai Junling and inability to accelerate?

The illumination of the EPC light on the dashboard indicates a problem with the power control management system of the vehicle's engine. It is necessary to clean the throttle or inspect the brake switch and wiring, and then identify the fault location for repair. Below are the functions and working principles of the EPC light: Functions of the EPC light: The EPC indicator light is more commonly seen in Volkswagen vehicles. After turning the ignition key, the vehicle begins a self-check, and the EPC light will illuminate for a few seconds before turning off. If the light remains on after starting the vehicle, it indicates a fault in the mechanical and electronic systems. Generally, there are two scenarios when the EPC light is on. One is a dirty throttle, which should be cleaned. The other scenario is when the brake light is not working, requiring inspection of the brake switch and wiring. Additionally, due to fuel quality issues, the EPC fault light may also illuminate. Working principles of the EPC light: Traditionally, drivers controlled the throttle opening by manipulating the accelerator pedal through a cable. In the EPC system, the previous throttle cable is replaced by sensors in the pedal assembly. The engine control unit (ECU) calculates the optimal target throttle opening based on the position data fed back by the pedal assembly sensors and sends a signal to the throttle drive motor to rotate the throttle to the desired angle.

What is the maximum tire pressure?

Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Other related questions: Is a tire pressure of 2.0 bar normal? No. According to the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. 2.0 bar is below the minimum standard tire pressure, so it is not normal. What is the normal tire pressure in winter? In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2 bar. What is the normal tire pressure in summer? Generally, the lower limit of the standard tire pressure is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. Tire pressure reset is the operation of resetting the tire pressure monitoring system after the tire pressure fault is resolved. Tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep," then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will go out, indicating the tire pressure reset is complete.

Will the ECU be damaged if it gets wet?

ECU will be damaged if it gets wet. Moreover, once the ECU is damaged, it cannot be repaired and must be replaced with a brand-new one. Relevant information is as follows: 1. There are many sensors and actuators on the engine. The ECU can collect data from the sensors, process it, and then control the engine operation through the actuators. 2. Both the ECU and TCU are usually installed in the engine compartment, so avoid using a high-pressure water gun to directly rinse the engine compartment during regular car washing, as this may damage the ECU and TCU. Cars equipped with automatic transmissions also have a TCU, which is the computer for the automatic transmission. The TCU can also collect data from various sensors, process it, and then control the automatic transmission's gear shifting through the actuators.

How to Identify the Year of TSG Glass?

TSG glass year identification is detailed as follows: 1. Year representation: This format of date code consists of a single digit, which represents the last digit of the year. It can be determined based on the vehicle's manufacturing date. For example, if the vehicle was manufactured in 2007 or 2008, the glass year digit '8' would indicate 2008. The production dates of the glass and the vehicle typically do not differ by more than 10 years. 2. Dot representation: Dots before the digit indicate the first half of the year, calculated as 7 minus the number of dots before the digit equals the month. Dots after the digit indicate the second half of the year, calculated as 13 minus the number of dots after the digit equals the month. For example, 13-1=December. 3. Asterisk representation: Some glasses may have small black asterisk-like dots following the year and month code. These asterisks can indicate the specific week of the month: 5 dots represent days 1-7, 4 dots represent 8-14, 3 dots represent 15-21, 2 dots represent 22-28, and 1 dot represents 28-31. Note that in some years, February has only 28 days, so a single asterisk would not appear. Additional information: 1. If the production date of the windshield is later than the vehicle's manufacturing date or close to your purchase date, it suggests that the vehicle was previously involved in a front-end collision, resulting in windshield damage and replacement. 2. For vehicle glass distribution, the production dates of all glasses in a vehicle are generally similar. If the year on one piece of glass differs from the others, it indicates that this piece has been replaced.
