How to solve the problem that the automatic transmission of Changan CS75 cannot shift gears?

What is the sensor on the negative terminal of the battery?

The sensor on the negative terminal of the battery is used to detect the current, voltage, and temperature of the battery. Relevant information about the sensor is as follows: Function of the battery sensor: It detects the current, voltage, and temperature of the battery. Under harsh driving conditions, it can accurately measure and monitor the voltage, current, and temperature of lead-acid and lithium-ion batteries, and can also calculate the remaining battery life. Introduction to sensors: A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules, to meet the requirements of information transmission, processing, storage, display, recording, and control.

Briefly describe how an engine works?

Engine working principle is: The battery provides electrical energy, under the control of the ignition switch and starter relay, the starter converts electrical energy into mechanical energy, driving the engine flywheel ring gear and crankshaft to rotate. Only when this starting cycle is completed can the engine enter self-sustaining operation. The car starting system working process: 1. Turn the ignition switch to ON position with the key, the dashboard powers on, and after several seconds the car enters ready-to-start state; 2. Turn the ignition switch to START position, connecting the battery and starting system circuit; 3. The starter relay receives power; 4. After the starter receives power, the main shaft rotates under electromagnetic force; 5. The drive gear on the starter's main shaft rotates, driving the engine flywheel and crankshaft to turn; 6. Under normal circumstances, after a brief starting process, the engine can enter automatic operation state.

What size tires should be replaced for Haval H6?

Haval H6 can be fitted with two sizes of tires: 235/55r19 and 235/60r18. Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help to absorb shocks during driving, ensuring good ride comfort and smoothness. They also ensure excellent adhesion between the wheels and the road, thereby improving the vehicle's traction, braking, and off-road capability. The Haval H6 is a compact SUV under the Haval brand, with dimensions of 4640mm in length, 1825mm in width, and 1690mm in height, and a wheelbase of 2680mm. It is equipped with either a 1.5GDIT or 2.0GDIT engine paired with a wet 7DCT powertrain.

If the lamination film of the driver's license peels off, you can go to the vehicle management office for a replacement. Below is relevant information about driver's license damage: 1. Relevant regulations: Article 60 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" stipulates that under any of the following circumstances, the motor vehicle driver shall apply for a replacement at the vehicle management office of the issuing authority or outside the issuing area within 30 days: (1) Within the jurisdiction of the vehicle management office, the motor vehicle driver's information recorded on the driver's license changes. (2) The motor vehicle driver's license is damaged and cannot be recognized. 2. Relevant materials: When applying, you should fill out the "Motor Vehicle Driver's License Application Form" and submit the following documents and proofs: (1) The identity proof of the motor vehicle driver. (2) The motor vehicle driver's license. (3) A physical condition certificate issued by a medical institution at or above the county level or the regimental level of the military. If applying for a driver's license for a small automatic passenger vehicle for the disabled, a physical condition certificate issued by a specialized medical institution designated by the provincial health authority must be submitted.

What is the meaning of wheel rim?

Wheel rim, commonly known as wheel ring, is the component installed around the wheel to support and mount the tire, forming the wheel together with the wheel spokes. The wheel rim and spokes can be integral, permanently connected, or detachable. The wheel hub is the rotating component that connects the wheel and axle, responsible for bearing the load between the tire and axle. The classification of automobile wheel rims is as follows: 1. Deep well rim: This type of rim is integral, with a deep groove in the middle of its cross-section. It has a flanged shoulder for mounting the tire bead, with the shoulder usually slightly inclined towards the center at an angle of 4 to 6 degrees. The maximum diameter of the inclined part is called the tire bead seat diameter. The deep groove in the middle of the cross-section facilitates the mounting and dismounting of the tire; 2. Flat base rim: There are many structural forms of this type of rim. The retaining ring is integral, and an open elastic lock ring is used to prevent the retaining ring from coming off; 3. Split rim: This type of rim consists of inner and outer parts. The width of the inner and outer rims can be equal or unequal, and they are bolted together. When mounting or dismounting the tire, only the nuts need to be removed. The inner rim is made with an integral flange to replace the function of the retaining ring, and the inner rim is welded to the wheel disc.

How to distinguish between genuine tires and retreaded tires?

The methods to distinguish between genuine tires and retreaded tires are as follows: 1. When replacing tires, carefully check the markings on the tire tread for Chinese color labels or black labels; verify if the tire name, specifications, load index, and speed rating on the Chinese label match those embossed on the tire sidewall; and check if there is a barcode on the tire bead. 2. Tires with artificially processed tread patterns are counterfeit. Genuine tires have very regular and clear tread patterns with deep grooves, giving a visually pleasing appearance. Counterfeit tires, due to significant damage to the tire body, require extensive modifications to the tread patterns. If the overall pattern appears irregular or deliberately altered to create visual interference, it is likely a counterfeit tire. When purchasing tires, carefully compare the tread patterns—disorganized patterns are a strong indicator of counterfeit tires. 3. Genuine tires have uniform tread thickness and consistent color. The tire body appears dull but has excellent elasticity and toughness. When touched, the tread feels soft with noticeable rubber particles and no pungent odor. Counterfeit tires are stiffer, with uneven tread thickness, and rough edges that are easily noticeable upon close inspection. 4. Retreaded tires usually have a layer of wax on the surface, making them appear unusually shiny. Pressing hard on the tread with a finger will leave a fingerprint, whereas new tires generally won’t show marks under similar pressure. Additionally, pull on the rubber studs and wear indicators on the "new" tire—genuine tires have better elasticity. Lightly scratch the tire surface with a key; genuine new tires usually won’t show scratches.
