How to Solve the P0504 Trouble Code?

P0504 trouble code can be resolved by replacing the brake switch. The causes of the P0504 trouble code include: water-induced short circuit in the brake switch; poor connection of the brake switch; damaged brake switch; related circuit faults; control unit faults. More information about the P0504 trouble code is as follows: 1. The P0504 trouble code refers to the correlation of Brake Switch A/B, expressed in English as: Brake Switch A/B Correlation. 2. The function of the brake switch: It transmits braking information in the form of electrical signals to the ECU to control the vehicle's speed, serving as an important basis for stopping cruise control and disengaging the torque converter. 3. The brake switch has two contact switches: normally open contact switch; normally closed contact switch. The brake switch controls the brake lights and ABS system, providing signals to the engine braking system.

Can You Add 95 Gasoline When 92 Gasoline Is Not Completely Used Up?

92 gasoline not completely used up can be mixed with 95 gasoline, which does not have much impact on the car and engine itself. However, since 92 gasoline has a lower compression ratio, it cannot fully utilize the characteristics of 95 gasoline, leading to "delayed combustion" and increased fuel consumption. Below is extended information about 92 and 95 gasoline: 1. The fundamental difference between 95 and 92 gasoline is the octane number: Simply put, the anti-knock agents added are different, with 95 gasoline containing a higher proportion of anti-knock agents than 92 gasoline. 2. Cars with a compression ratio greater than 9.5 should use 95 or 92 gasoline: Currently, the compression ratio of domestic cars is mostly above 9.

When Should the Vehicle Position Lights Be Turned On?

Vehicle position lights should be turned on when it is not completely dark yet. Here is a partial introduction to position lights: 1. Position lights are also called clearance lights: They are used during evening driving to allow other drivers to judge the size and width of the vehicle ahead. 2. The position lights will automatically turn on when the vehicle's lights are activated: Position lights are located at the rear of the car, with one on each side for small vehicles, and more for larger vehicles. 3. When the position lights are on, the distance between the two beams is roughly equal to the width of the vehicle: If you are unsure whether the vehicle can pass through a narrow intersection, you can also turn on the position lights.

What does the DOT on tires mean?

DOT is the abbreviation for the U.S. Department of Transportation. The "DOT" marking indicates that the tire meets the safety standards set by the U.S. Department of Transportation. Here is an introduction to DOT: 1. The 11-digit number and letters immediately following "DOT" represent the tire's identification number or serial number. DOT is divided into three levels: A, B, and C, with Level C being the lowest, meeting only the minimum performance conditions specified by the U.S. Department of Transportation (DOT). The other two levels exceed the DOT requirements. 2. According to U.S. law, all tires sold in the U.S. market must pass DOT testing and have the DOT mark molded on the tire sidewall after certification. Tires without the DOT mark are not allowed to be imported, produced, or sold in the U.S. market. 3. The tires of these specifications produced by the company are currently only sold in the Chinese market and are not exported to the U.S., so the sidewall does not need to be molded with the DOT mark.

How Many Spark Plugs Does a Car Have?

Generally, a gasoline-powered car has one spark plug per cylinder, but there are exceptions. For example, the Nissan Bluebird U11 and Honda Fit 1.5 have two spark plugs per cylinder, meaning a four-cylinder engine in these models would have eight spark plugs. Below is an introduction to the types of spark plugs: 1. Standard Spark Plug: The insulator skirt is slightly recessed into the shell end face, and the side electrode extends beyond the shell end face. This is the most widely used type. 2. Extended Insulator Spark Plug: The insulator skirt is longer and protrudes beyond the shell end face. It has advantages such as high heat absorption and good anti-fouling performance, and it can be directly cooled by incoming air to lower temperature, reducing the risk of hot spots. Thus, it has a wide thermal adaptability range. 3. Fine Electrode Spark Plug: The electrode is very thin, featuring strong sparks and excellent ignition capability. It ensures quick and reliable engine starts even in extremely cold weather and has a wide thermal range, suitable for various applications. 4. Tapered Seat Spark Plug: The shell and threaded insert are conical, allowing good sealing without the need for a gasket. This reduces the spark plug's size, benefiting engine design. 5. Multi-Electrode Spark Plug: Typically has two or more side electrodes. Its advantages include reliable ignition and no need for frequent gap adjustments, making it suitable for gasoline engines where electrodes are prone to erosion and spark plug gaps cannot be adjusted regularly. 6. Surface Gap Spark Plug: Also known as a surface discharge type, it is the coldest type of spark plug, with a concentric gap between the center electrode and the shell end face.

What is the CMA Platform?

CMA architecture is a new framework jointly developed by Volvo Cars and Geely Auto, with Volvo Cars taking the lead. The new-era premium joint-venture brand Lynk & Co is built upon this architecture. This modular architecture can cover the development of vehicles ranging from A0 to B-segment, including sedans or hatchbacks, and even SUVs. Below is an introduction to the CMA architecture: 1. The modularity is reflected in the CMA architecture's component-based development of vehicle parts such as the body, chassis, power and drive systems, and electronic systems. Simply put, these components can be combined with each other. Therefore, if the development of these components maintains a high level of quality and compatibility, the assembled vehicle models will undoubtedly be of high quality as well. 2. The safety advantage of the CMA "Intelligent Magic Cube" lies in the close integration of active and passive safety technologies, providing stronger protection for vehicle occupants. Safety is also a major feature of the Lynk & Co brand, with all models adhering to stricter safety standards. The roof crush resistance can exceed 4.5 times the vehicle's weight. For reference: the Chinese standard requires exceeding 3 times the vehicle's weight, while the U.S. standard requires exceeding 4 times. Additionally, the 360° ultra-strong safety body structure meets the crash test standards of North America, Europe, and China.
