Subaru Forester brake lights not working reasons and solutions are as follows: Check the brake light bulb: The most frequently used light in a car is the brake light, and the bulb has a relatively short lifespan. Solution: When the car's brake lights are not working, the first thing to consider is the brake light bulb. Replacing the bulb should solve the problem. Check the brake light switch: If the brake light switch is faulty, none of the brake lights will work. Solution: During inspection, you can connect the brake light switch with a wire. If the brake lights turn on, it indicates the switch is damaged. Replacing the switch will resolve the issue. Check the fuse: If both the bulb and switch are confirmed to be functioning properly, the next step is to check the fuse. Some cars do not have a separate fuse for the brake lights and share one with other electrical devices. Solution: In this case, check the operation of other electrical devices in the car. Identify any non-functioning devices and replace the corresponding fuse. Check the brake light ground wire: The tail lights in a car share a common ground wire. Solution: If the ground wire is broken or has a poor connection, it can also cause the brake lights to fail. Therefore, do not forget to check the ground wire.

What Causes the Continuous Alarm Sound in Geely Boyue?

In vehicles, the ground wire is part of the circuit loop. However, sometimes it is observed that a large number of electrical devices rely on only one or two ground wires to transmit current. This is because many electronic circuits involve digital signals and high-precision analog signal circuits. If there is poor contact in the ground wire, it is equivalent to adding a resistor in series in the circuit, which may cause high-precision signals to become inaccurate. Here is additional information: Car Anti-Theft Alarm: The car anti-theft alarm is a multifunctional product that not only serves as an anti-theft alarm but also can remotely open the trunk, remotely open and close doors, remotely open and close windows, remotely start the engine, and remotely lock the engine, among other functions. The continuous sounding of the car alarm may be due to a fault in the main control door ground wire, commonly known as a door switch fault.

What does AUTO mean for car lights?

Car light AUTO refers to a system that automatically controls the turning on and off of lights based on environmental conditions, also known as automatic headlights, which is a system installed by car manufacturers for user convenience. When the car light is set to this position, the lights will automatically turn on when passing through tunnels or in dimly lit areas; when exiting the tunnel or when there is sufficient light, the lights will automatically turn off. Car headlights, also known as car front lights or car LED daytime running lights, serve as the eyes of the car. They not only relate to the external image of a car owner but are also closely linked to safe driving at night or under bad weather conditions. Car headlights are categorized into halogen lamps, xenon lamps, LED lamps, laser lamps, etc.

What is the temperature resistance of automotive ABS plastic?

Automotive ABS plastic has a heat deflection temperature of 93~118°C, and the product can be increased by about 10°C after annealing treatment. ABS can still exhibit certain toughness at -40°C and can be used in the temperature range of -40~100°C. Below is a detailed introduction to automotive ABS plastic: 1. Overview: ABS plastic is a ternary copolymer of three monomers: acrylonitrile (A), butadiene (B), and styrene (S). The relative content of the three monomers can be varied arbitrarily to produce various resins. 2. Function: ABS plastic combines the common properties of the three components: A makes it resistant to chemical corrosion and heat, and gives it a certain surface hardness; B provides high elasticity and toughness; S gives it the processing and molding characteristics of thermoplastic and improves electrical properties.

What is the principle of car steering?

The principle of car steering is that the steering wheel drives the steering gear, which in turn causes the rack and pinion steering mechanism to function, making the front tie rod swing left and right to create an angle in the front wheels, thereby achieving the steering effect. The car steering system is used to maintain or change the direction of the car's movement or reverse. The car steering system is divided into mechanical steering systems and power steering systems. The mechanical steering system mainly uses the driver's physical strength as the steering energy source and consists of the steering control system, steering gear, and steering transmission system. The power steering system uses both the driver's physical strength and the engine's power as the steering energy source, making it more convenient to use compared to the mechanical steering system.

Is it necessary to replace the filter when changing transmission fluid?

When changing transmission fluid, it is essential to replace the filter. Failure to do so may allow contaminants to directly enter the transmission. Transmission fluid is a lubricant that maintains the cleanliness of the gear system, primarily ensuring proper transmission operation and extending the lifespan of the transmission components. Depending on transmission design, it is categorized into manual transmission and automatic transmission. The steps for changing transmission fluid are as follows: 1. Start the engine to warm up the transmission to operating temperature; 2. Remove the drain bolt; 3. After draining the old fluid, reinstall the bolt; 4. Add new ATF fluid; 5. Shift through gears from P to N, D, L1, L2, etc., pausing for at least 5 seconds in each gear; 6. Check if the automatic transmission fluid level is normal.
