How to Remove the ETC Device from the Car?

Steps to remove the ETC device from the car: 1. Prepare a piece of fishing line. 2. Wear a pair of rubber gloves, such as those used for dishwashing or laundry. 3. Straighten the fishing line with both hands. Pull it forcefully downward from the top of the ETC device. If it is stuck too tightly, you may need to pull several times, then use the fishing line to cut through. 4. After cutting, use a wet wipe to clean any residue left on the windshield. Below is some related information: ETC (Electronic Toll Collection) is a non-stop toll collection system used on highways or bridges. It works through dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station. This system utilizes computer networking technology for backend settlement processing with banks, allowing vehicles to pass through highway or bridge toll stations without stopping while still paying the required fees.

How to troubleshoot P0170 Fuel Trim 1?

p0170 Fuel Trim 1 troubleshooting methods are as follows: 1. According to the setting conditions of the fault code, the relevant detection methods include whether the fuel pressure is correct, whether the intake and exhaust systems are leaking, and whether the air flow meter signal is normal. 2. Based on the status displayed by the oxygen sensor's voltage signal, a clogged fuel injector can lead to insufficient fuel injection [more air results in less fuel injection, making the air-fuel ratio lean, causing idle shaking and low oxygen sensor signal voltage]. 3. Air flow meter - signal deviation - cannot meet the normal air-fuel ratio formation conditions, leading to mixture imbalance. Incorrect fuel pressure - either too low or too high - will result in incorrect mixture concentration. 4. The engine ECM judges through the oxygen sensor signal voltage. If it deviates from the set value stored in the memory and meets the fault setting conditions, the corresponding fault code will be stored.

Why does the car always fail to start?

There are several reasons why a car may fail to start: 1. Dead battery: When the car battery is dead, the car won't start. There are many reasons for a dead battery, such as lack of water in the battery, battery failure, or prolonged use of the air conditioning. If the car doesn't start, the first thing to check is whether there is a problem with the car battery and what the issue is, then take it to a 4S shop for repair. 2. Low temperature: In cold winter weather, cars often have trouble starting. This is because in low-temperature environments, the viscosity and rotation speed of the car's engine oil decrease, leading to reduced ignition energy from the battery and decreased molecular activity, making it difficult to form flammable gases and thus hard to start the car. 3. Carbon buildup: Carbon buildup in the car engine can cause many problems, the most common being difficulty starting the car. There are many reasons for engine carbon buildup, such as excessive water in gasoline, poor fuel quality, or poor sealing of the valve seat rings. So if the car is hard to start, it might be worth checking if there is a lot of carbon buildup in the engine and cleaning it promptly if necessary.

How to Clean Cement off a Car?

Here are the methods to clean cement off a car: 1. Before it hardens, you can wet it with clean water and rinse it off, then use a towel with cleaning solution to wash it. 2. If the cement is not discovered and treated in time and has already solidified, you can use an acidic solution to clean it, such as common white vinegar. White vinegar is an acidic liquid that can effectively dissolve cement. Pour white vinegar onto the cement attached to the car, wait a few minutes for the cement to soften, and then it will be easy to clean. 3. You can also purchase cement cleaning agents for cleaning, and the cleaning method is the same as with white vinegar. Small areas of cement can be considered for self-cleaning, but if the area is large, it is recommended to go to a professional car wash shop for cleaning, as they have specialized cleaning agents and more professional cleaning techniques.

What is the correct way to use the turn signals on the steering wheel?

Turn signal operation can be summarized with four words: up, right, down, left. Specifically, pushing the turn signal up (clockwise) indicates a right turn, while pushing it down (counterclockwise) indicates a left turn. Here is some related information: 1. Activate the turn signal in advance. When preparing to turn, you should activate the signal 10-20 seconds ahead to give following drivers enough time to react. However, the exact timing may vary depending on road conditions, traffic, and speed, but generally, it should not be less than 10 seconds. 2. In parking lots where speeds are low, you can activate the turn signal early upon spotting an available parking space, slow down, and if possible, drive directly into the space head-first. 3. If you need to reverse into a parking space, don’t rush. First, activate the turn signal, then position your car horizontally in front of the space. It’s best to block the entrance with the front of your car rather than fully entering the space immediately, giving vehicles behind you some reaction time.

Why doesn't the car move after shifting into gear in an automatic transmission?

The car not moving could be due to reasons such as oil leakage, clogged filter screen, or oil pump damage. Here is the relevant information: 1. If a large amount of hydraulic oil sprays out from the pressure test hole, it indicates that the main oil circuit pressure is normal, and the fault lies in the input shaft, planetary gear set, or output shaft of the automatic transmission. The automatic transmission should be disassembled for inspection. 2. Check whether the linkage or cable between the automatic transmission control lever and the manual valve rocker arm is loose or detached. If it is loose or detached, it should be reinstalled and the position of the control lever readjusted. 3. If only a small amount of hydraulic oil flows out from the main oil circuit pressure test hole, with low or almost no oil pressure, the oil pan should be opened to check if the oil pump inlet filter screen is clogged. If there is no clogging, it indicates that the oil pump is damaged or there is a serious leak in the main oil circuit. The automatic transmission should be disassembled and inspected. 4. Remove the plug from the main oil circuit pressure test hole, start the engine, shift the control lever to the drive or reverse position, and check whether hydraulic oil flows out from the pressure test hole.
