How to Determine Hydraulic Pump Damage?

About the specific methods to determine hydraulic pump damage are as follows: 1. Bearing damage: The judgment method is to observe whether the shaft is shaking. If shaking occurs at high speed, it indicates that the bearing is damaged. 2. Poor oil quality: If the oil quality is poor or does not meet standards, the vehicle's pressure value will fail to meet requirements. 3. Inner tank rust: If the hydraulic pump is damaged due to rust in the hydraulic oil pump's inner tank, the judgment method is to manually clean the inner tank. This usually occurs after prolonged use. Check if the oil refill amount is less than before.

What to Do When the Key Can't Be Pulled Out?

Regarding the reasons and solutions for the key not being able to be pulled out: 1. Incorrect pulling method: After parking and turning off the engine, accidentally turning the steering wheel left or right or parking with the wheels not straight can cause the steering wheel to rotate under force, activating the steering wheel's self-locking function. This causes the steering lock pin and steering column to interlock, making the steering wheel immovable, and even inserting and turning the key with force won't work. Solution: While gently turning the key with your right hand, shake the steering wheel left and right with your left hand, and the key can then be turned. 2. Incorrect gear position: The reason the key can't be pulled out after turning off the engine is that the gear is not properly engaged in the P position, not touching the electronic sensor, or there are objects like coins in the gear slot blocking proper engagement. Solution: Check if there are any obstructions in the gear slot and remove them.

Reasons for Weak Wiper Motor?

The reasons for weak wiper operation may include lack of lubrication in the linkage mechanism, short circuit in the wiper motor coil causing weakness, or aging and weakening of the wiper arm spring. Detailed analysis of weak wiper operation: Since wiper blades are rubber products, they tend to age over time, affecting their performance. A dirty windshield with oil film can cause the motor to malfunction and operate weakly during cleaning. There may be poor electrical connections in the wiper motor's power supply, leading to abnormal motor operation and occasional weak wiper performance. Solutions: Check the wiper motor - it can be seen after opening the car hood. Touch the wiper motor with your hand; if it feels hot, it indicates an internal short circuit and the motor needs replacement. Check the wiper fuse - each electrical device in the car has a fuse for circuit protection. If the wipers don't work, check if the wiper fuse is blown and replace it with a spare fuse from the vehicle.

How to Control Speed When Driving on Muddy Roads?

When driving on muddy roads: Use medium to low gear, hold the steering wheel steadily, maintain a constant speed by stabilizing the accelerator pedal, and try to pass through in one go without using the service brake to prevent the vehicle from sliding. Below are some precautions for driving on muddy roads: 1. Be cautious when going downhill: Always select medium to low gear when descending, reduce the throttle, and descend slowly. Never coast downhill in neutral. Braking is often required during descent to avoid obstacles, especially on dirt roads with sharp turns. Coasting in neutral while braking can easily cause the vehicle to deviate, skid sideways, or even roll over, leading to serious accidents. 2. Pay attention to safe overtaking: Avoid following the vehicle in front too closely to prevent dust (on sunny days) or mud splashes (on rainy days) from obstructing your view. When encountering oncoming traffic, observe the road surface carefully, especially during prolonged rain, and avoid getting too close to the shoulder to prevent side-slip accidents.

What Are the Causes of Low Idle Vibration?

Engine low idle vibration can be caused by severe carbon deposits in the engine, issues with the ignition system, unstable oil pressure, etc. Severe engine carbon deposits: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the fuel injector during a cold start will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Only when the carbon deposits become saturated with gasoline will the engine start easily. The lower the temperature, the more fuel is required for a cold start, and the presence of carbon deposits will significantly affect the success of the cold start. Therefore, it is necessary to clean the fuel system. Issues with the ignition system: Check the working condition of the spark plugs, high-voltage wires, and ignition coils, as poor performance of the ignition system or weak sparking from the spark plugs can also cause low idle vibration during engine startup. If any problems are found with the ignition system after inspection, it is necessary to promptly replace components such as spark plugs. Unstable oil pressure: If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect or malfunctioning, it can also cause vehicle vibration. In this case, it is necessary to check the oil pressure and replace components if needed.

How to Cancel the Previous Owner's ETC?

Here are the detailed methods for canceling the previous owner's ETC: 1. When purchasing a new car and keeping the old license plate previously used for ETC service: Remove the ETC device, bring the device along with your ID card and the new car's vehicle license to the original ETC service point to update the information and reactivate the device. 2. When purchasing a new car and changing to a new license plate: Remove the original ETC device, go to the issuing bank to cancel the service, and then apply for a new ETC for the new car. 3. If you no longer wish to use ETC: Bring the relevant documents to the original ETC service point to cancel the service. If there is any remaining balance on the card, it can be refunded.
