Where to Install ETC on a Vehicle?

The ETC device is generally installed on the upper middle part of the front windshield for passenger cars, while for large vehicles such as trucks and buses, it is installed on the lower middle part. The recommended installation height is between 1.2 meters and 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket anti-explosion film, which may interfere with microwave signal transmission, the device should be installed in the microwave window area. ETC stands for Electronic Toll Collection. To apply for an ETC device, the vehicle owner must provide original and photocopied documents of their valid ID and vehicle registration certificate. If the application is handled by a proxy, the proxy's valid ID is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A personal bank card for deducting highway tolls is required, and the vehicle must be registered under the name of an individual aged between 18 and 60. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with company seal); a photocopy of the organization code certificate or business license (with company seal); the original ID of the proxy; the original vehicle registration certificate; and the vehicle for which the ETC is to be installed. Here are some important considerations for ETC installation: Do not obstruct the driver's view—it is best to install the device behind the rearview mirror. Many vehicles have windshields with a steep incline, which can reduce the driver's field of vision. Installing the ETC device improperly may increase blind spots. The optimal position is behind and to the right of the rearview mirror to avoid blocking the view. Ensure the device can charge properly: The ETC device requires power but generally does not need manual charging or battery replacement, as it has a built-in solar panel. Therefore, avoid installing it on the blackened areas of the windshield or any location that might block the solar panel. Once installed, do not remove the device arbitrarily: The adhesive backing includes an anti-tamper switch. When installed correctly, the windshield presses this switch in. If the device is removed, the switch will pop out, locking the device and requiring an ETC service center to unlock it. This feature prevents multiple vehicles from sharing one device. Usage tips for ETC: The ETC sensing range is 8 meters. To avoid accidental toll payments for the vehicle ahead due to device malfunction, maintain a distance of at least 10 meters from the preceding vehicle. The ETC lane recognizes vehicles at speeds up to 20 km/h—exceeding this speed may result in failed toll deductions. Additionally, insufficient balance on a debit card linked to ETC can also cause payment failures.

What are the symptoms of a failing thrust bearing?

Automotive thrust bearing failure symptoms include a "clicking" noise when turning the steering wheel, or a "thumping" sound when rotating the steering wheel while stationary or at low speeds. Other signs include steering wheel vibration, heavier steering feel, noticeably increased tire noise during driving, abnormal sounds when passing over speed bumps, vehicle pulling to one side, damage to the steering system, and suspension system damage. More detailed explanations are as follows: 1. Automotive thrust bearings, also known as pressure bearings, are most commonly found in MacPherson strut suspension systems. This is because the MacPherson strut design uses the spring shock absorber as the load-bearing pillar, which also serves as the pivot point for left and right steering movements in combination with the steering knuckle. 2. The thrust bearing is located at the top of the shock absorber, positioned between the spring and the shock absorber top mount. It must withstand vertical pressure while allowing free rotation, making it a crucial component for MacPherson suspension systems.

Is It Okay to Not Change Transmission Fluid for 8 Years?

It is not advisable to go without changing transmission fluid for 8 years. Transmission fluid primarily serves to lubricate, clean, and seal the transmission. Over time, the fluid quality deteriorates, and impurities may form. Here is some information about transmission fluid: 1. Functions of Transmission Fluid: It is an oil product that keeps the gear system clean, lubricates to prolong the lifespan of transmission components, provides effective lubrication even in low temperatures, and reduces fluid loss under harsh operating conditions. 2. Characteristics of Transmission Fluid: Most transmission fluids on the market are compatible with current automatic transmissions. However, each automatic transmission design has unique technical requirements. Even the same transmission model used in different vehicles may vary in torque, weight, speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluid.

What is the safest speed to drive on the highway?

Highway speed limit signs indicate that the maximum speed should not exceed 120 kilometers per hour. Here are some precautions for driving on the highway: Control your speed: The highway imposes strict speed limits. According to national regulations, the maximum speed on the highway should not exceed 120 kilometers per hour, and the minimum speed should not be lower than 60 kilometers per hour. Driving too fast increases the likelihood of traffic accidents, while driving too slow can obstruct following vehicles and hinder the efficiency of the highway. Maintain a safe distance: Vehicles in the same lane must keep a sufficient distance from the vehicle in front to allow for valuable reaction time in case of emergencies. Visibility is lower when driving at night, so additional space should be maintained between vehicles. Stay in your lane: Drivers should always pay attention to roadside and road surface markings. It is not permitted to straddle or drive on lane dividers, nor is it allowed to occupy the overtaking lane for an extended period.

What are the types of throttle position sensors?

1. Hall-effect throttle position sensor: It mainly consists of a Hall element and a magnet. The magnet is mounted on the throttle shaft and can rotate around the Hall element. When the throttle opening changes, the magnet rotates accordingly, altering its relative position to the Hall element, which is surrounded by a magnetic yoke. The Hall integrated circuit converts the changes in magnetic flux into electrical signals and outputs them to the ECM as throttle position signals. 2. Dual variable resistance throttle position sensor: In this type, two sensors are usually installed together. If one sensor fails, it can be promptly identified, enhancing system reliability. Based on the changing relationship of the output signals from the two sensors, there are two types: reverse-phase and same-phase. The same-phase type can be further divided into linear changes with the same slope and linear changes with different slopes. 3. Sliding resistance throttle position sensor: Also known as a linear output throttle position sensor, variable resistance throttle position sensor, or potentiometer-type throttle position sensor. Currently, dual variable resistance throttle position sensors are widely used in automobiles.
