How to Solve the Flickering Issue of an Aftermarket Rearview Camera?

Here are the solutions for a flickering rearview camera: 1. For poor contact in the rearview camera wiring: Check the wiring of the rearview camera to see if there are any loose connections at the terminals. If found, reconnect them properly. If the wiring is aged, replace the power cable with a new one to resolve the flickering issue. 2. For a faulty rearview camera: If the rearview camera has been used for an extended period, it may cause flickering. In this case, it is best to take it to a repair shop for inspection or replacement. 3. For insufficient voltage: When the car starts, the voltage may drop momentarily. Since the rearview camera requires a stable voltage, insufficient power supply can cause the screen to flicker. In such cases, it is advisable to have it checked at a repair shop.

I installed a rearview camera, and sometimes the screen flickers. I've dealt with it myself a few times. Generally, start by checking the wiring to see if the connectors are loose or have poor contact, especially the power and ground wires, which can easily get dirty or rusty due to debris, leading to unstable current. Use a damp cloth to clean the connectors and then tighten them. Power supply issues are also common—voltage fluctuations when starting the car can overwhelm the camera. It's best to use a multimeter to check the voltage, which should normally be in the 12-14V range. If fluctuations are significant, adding a voltage regulator can help. Poor-quality cameras can also cause flickering. If waterproofing wasn't done properly during installation, rainwater seepage can cause short circuits, leading to this issue. In my case, the camera was loosely installed by a roadside shop, and I fixed it by reopening and securing the cables properly, which solved the problem. Driving safety comes first—don't delay, as poor visibility while reversing can easily lead to collisions. I recommend starting with simple self-checks; if that doesn't work, visit a professional modification shop—they have the tools to troubleshoot circuits. During regular maintenance, pay attention to protecting wiring connections from moisture and dust to extend their lifespan. When choosing products, opt for reputable brands for better reliability—don't skimp for the sake of convenience.

What is the minimum ground clearance of the Exeed VX?

The minimum ground clearance of the Exeed VX is 240mm. The minimum ground clearance of the Exeed VX refers to the distance between the lowest point (excluding the wheels) and the supporting plane, which indicates the vehicle's ability to pass over obstacles such as rocks and tree stumps without collision. A higher ground clearance generally improves off-road capability, but if the Exeed VX's ground clearance is too high, it may reduce stability at high speeds. The Exeed VX, designed in 2019, has the following body dimensions: length 4970mm, width 1940mm, height 1788mm, and a wheelbase of 2900mm. Typically, sedans have a ground clearance ranging from 110mm to 150mm, while SUVs have a ground clearance between 200mm and 250mm. However, the Exeed VX's ground clearance is not static—it varies depending on the load condition. Therefore, changes in ground clearance should be considered based on the vehicle's load. When selecting a vehicle, ground clearance can be one of the reference factors. The choice should depend on the vehicle's intended use and road conditions. For urban driving on well-paved roads, a lower ground clearance may enhance stability and comfort. For frequent travel on rough or off-road terrains, a higher ground clearance is advisable to avoid underbody scrapes or damage.

What is the engine speed when the car is running at 120 mph?

When the car is running at 120 mph, the engine speed is generally around 3400 RPM. Below is relevant information about engine speed: Introduction to Engine Speed: The level of engine speed relates to the number of work cycles per unit time or the effective power output of the engine, meaning the effective power varies with different speeds. Therefore, when specifying the effective power of an engine, the corresponding speed must also be indicated. The effective power and its corresponding speed specified on the engine's product label are referred to as the rated power and rated speed, respectively. The operating condition of the engine at rated power and rated speed is called the rated condition. The rated power is not the maximum power the engine can produce; it is the maximum usable limit of effective power determined based on the engine's intended use. For the same engine model, the rated power value may differ depending on its application. Effective torque also varies with engine conditions. Thus, the maximum torque a car engine can output and its corresponding speed are used as indicators to evaluate the engine's dynamic performance. Speed Measurement: Typically, a speed sensor is used, corresponding to the signal teeth on the flywheel, to measure the engine speed.

At What RPM Should You Shift Gears in a Sedan?

Ordinary cars typically shift gears between 2000 and 3000 RPM, but shifting from first to second gear is often done at a lower RPM, around 2000 RPM or slightly higher. Some engines are designed for low RPM operation, producing relatively high torque and power at lower RPMs. These engines can shift gears at around 2000 RPM or even between 1500 to 1800 RPM. Below is some relevant information about shifting gears: Shifting Up Techniques: The key to smooth upshifting lies in the "acceleration surge" magnitude. The "acceleration surge" distance should be determined by the gear being shifted to—the higher the gear, the longer the "acceleration surge" distance. During the "acceleration surge," the accelerator pedal should be pressed steadily and released quickly at medium speed. Shifting Down Techniques: Release the accelerator pedal, quickly press the clutch pedal, move the gear lever into neutral, then release the clutch pedal. Quickly tap the accelerator pedal with your right foot (adding "empty throttle"), then press the clutch pedal again quickly, move the gear lever into the next lower gear, and release the clutch pedal using the quick-pause-slow technique to allow the car to continue driving in the new gear.

What are the steps to remove a car's interior headliner?

Car headliner removal mainly involves the following steps: 1. First remove the four door handles. 2. Then remove the front and rear dome lights. 3. Next, pull off the decorative panel at the rear of the headliner. 4. Finally, remove two screws before pulling it down. Additional information: 1. The car headliner is an important component of automotive interiors, serving decorative, sound-absorbing, and heat-insulating functions. 2. In an era increasingly focused on high performance, environmental friendliness, and lightweight design, interior headliners have become a significant factor in vehicle selection, leading to increasingly higher requirements for automotive interior components.

Can I Take Subject Three If I Failed Subject Two?

You can take Subject Three even if you failed Subject Two. Additional information about the driver's license test is as follows: Driver's License Test Content: The driver's license test is divided into the Road Traffic Safety Laws, Regulations, and Related Knowledge Test (also known as the "Theory Test," hereinafter referred to as "Subject One"), the Field Driving Skills Test (commonly known as the "Pole Test," hereinafter referred to as "Subject Two"), and the Road Driving Skills and Safe Driving Common Sense Test (commonly known as the "Road Test," hereinafter referred to as "Subject Three"). The test content and passing standards are uniform nationwide, with corresponding test items specified for different types of vehicles. Conditions for Each Subject of the Driver's License Test: Subject One can be scheduled once the application materials are approved, usually about a week after scheduling. Subject Two can be scheduled more than ten days after passing Subject One. Subject Three can be scheduled one month after passing Subject One. Subject Four can be taken once without scheduling on the same day after passing Subject Three. For any failed subject from Subject One to Subject Four, you must wait ten days before rescheduling. It can be seen that the order of Subject One and Subject Four cannot be changed, but the order of Subject Two and Subject Three can be completely swapped as long as the time requirement after passing Subject One is met.
