What does SVS on the car dashboard mean?

The SVS on the dashboard is a fault indicator light, which is illuminated by the ECU or TCU of an electronically fuel-injected car when it detects a problem with the engine or automatic transmission. All electronically fuel-injected cars have an SVS fault indicator light. For manual transmission models, it serves as the engine fault indicator light, while for automatic transmission models, it indicates both engine and automatic transmission faults. More information about the SVS light is as follows: 1. The SVS light is a standard indicator in the automotive industry, responsible for warning of abnormalities in the powertrain system and prompting users to have the vehicle serviced. When the powertrain system's self-diagnosis detects an abnormality, the SVS light will alert the user to service the vehicle. 2. The SVS light alarm may originate from the engine, transmission, or gear shift mechanism. When the SVS light flashes, it indicates a current fault in the powertrain system that requires servicing. The car's SVS light is similar to the engine fault light. When the SVS indicator is on, it means the engine control unit has detected an erroneous signal from a sensor or that a component has exceeded its usage standard. 3. When the ignition is turned on, the car's SVS indicator light will illuminate for an automatic check and will turn off automatically after a few seconds.

What are the symptoms of a damaged car check valve?

Car check valve damage will increase nitrogen oxide emissions, cause engine oil deterioration, and increase fuel consumption. Here is some information about car check valves: 1. A check valve, also known as a non-return valve or one-way valve, is used in hydraulic systems to prevent reverse oil flow, or in pneumatic systems to prevent compressed air from flowing backward. 2. Check valves are used in applications where reverse airflow is not allowed. For example, when an air compressor fills an air tank, a check valve is installed between the compressor and the tank. When the compressor stops working, it prevents compressed air in the tank from flowing back into the compressor.

How to Read Tire Batch Numbers?

The production batch number of a tire: Look for the marking on the sidewall that reads "**A**C****", where "*" represents a digit, and "A and C" represent any English letter. A combination of numbers and letters is used as a "mark" to indicate the manufacturing year, month, and quantity, also known as the "production batch number". For example, "97N08C1820" means the 1820th tire produced in group C in August 1997. The production batch number is used to identify the age and storage time of the tire. There are many numbers and letters on a tire. Taking 225/50-R18-94H-ZG as an example, here is a detailed analysis of their meanings: 1. 225: Indicates the tire's section width is 225mm; 50: Indicates the tire's aspect ratio is 50%; ZG: Indicates the tire type is steel-belted radial tire. 2. R18: Indicates the wheel diameter is 18 inches; 94: Indicates the maximum load capacity of a single tire is 670kg; H: Indicates the maximum speed of the vehicle should not exceed 210km/h.

What Causes Noise in Newly Replaced Brake Pads?

It is normal to hear noise when braking after replacing new brake pads. There is a break-in period required between the brake pads and brake discs, which usually takes about 500 kilometers to complete. The brake discs may have been worn unevenly by the old brake pads, while the surface of the new brake pads is smooth. Initially, the contact area between the new brake pads and the brake discs is small, which can cause noise during the break-in process. If there is abnormal noise after replacing new brake pads, the following reasons may be the cause: 1. The brake pads may contain metal wires or other hard material particles of larger size. When the brake pads wear down to these materials, they may produce noise against the brake discs. After further wear, the noise will disappear and will not affect safety. 2. After replacing new brake pads, incorrect installation may cause noise. Common installation errors include installing the brake pads upside down, with the metal side facing the brake disc, which can lead to abnormal noise. 3. Sand or debris in the brake discs may cause noise: If foreign objects such as sand or small stones get between the brake pads and brake discs while driving, the brakes may produce a sharp hissing sound. Continuing to drive normally will usually dislodge the debris, eliminating the noise. If the noise persists for a long time, it may be necessary to remove the wheel and extract the debris.

What are the components of an electronic steering system?

Electronic steering systems are primarily composed of two main parts: sensors and actuators. In an electric four-wheel steering system, both the front and rear wheel steering mechanisms are electrically assisted. There are no mechanical linkages or hydraulic pipelines between the two steering mechanisms, allowing direct control of the front and rear wheel steering. This system offers advantages such as precise control of the steering angle relationship between front and rear wheels, high degree of control freedom, and simple mechanical structure. The following is an introduction to four-wheel steering systems: 1. There are two main types of four-wheel steering: same-phase steering, where the rear wheels turn in the same direction as the front wheels; and opposite-phase steering, where the rear wheels turn in the opposite direction to the front wheels. 2. The purpose is to improve the vehicle's operational stability during high-speed driving or under lateral wind forces, enhance maneuverability at low speeds, and reduce the turning radius in parking lots.

What does the front and rear position lamp mean?

Position lamp (position-lamp) refers to the four flashing lights at the front, rear, left and right sides when the hazard warning lights are turned on, which are also known as vehicle width indicator lights. Width indicator lights are turn signal lights that flash simultaneously to serve as a warning, suitable for use during night driving. More information about vehicle position lamps is as follows: 1. The function of position lamps is to indicate the outline size of the vehicle, so that front and rear vehicles can distinguish the size and position of the vehicle in dimly lit environments. 2. The control switch is the light knob. For models with only manual light-on function, turning the light knob one notch turns on the width indicator lights (turning it another notch turns on the headlights). For models with automatic headlights, when the switch is turned to the "AUTO" position, the outline lights will automatically turn on when the ambient light is dim. 3. The front position lamps emit white light, while the rear position lamps mostly emit red light, with a bulb power of 8~10W.
