The following are the components of an automobile system: 1. Engine, chassis, and body. 2. Auxiliary electrical appliances and electronic equipment. Below is an introduction to the auxiliary electrical appliances and electronic equipment: 1. Auxiliary electrical appliances: automobile generator, battery, engine ignition and starting equipment, lighting and signaling equipment, instruments, air conditioning, wipers, audio and video equipment. 2. Electronic equipment: electronically controlled fuel injection system and ignition system, electronically controlled automatic transmission, anti-lock braking system (ABS), electronic traction control system, brake force distribution system, electronic stability program (ESP), torque vectoring system. Below is extended information about automobile braking system malfunctions: 1. When pressing the brake pedal, the pedal does not rise and there is no resistance. 2. When the brake pedal is pressed all the way down, the braking effect is poor; continuous braking does not improve the effect, and the pedal gradually rises. 3. Continuous braking causes the pedal to return and rise, with some improvement in braking effect. 4. Continuous braking causes the pedal position to rise, accompanied by a sinking sensation.

I think automotive systems can be divided into several main components. The engine system is the core, responsible for generating power, including the combustion chamber, intake and exhaust, cooling, and lubrication. Then there's the drivetrain system, like the transmission, clutch, and differential, which transfer power to the wheels to propel the vehicle forward. The braking system is essential, with brake discs and calipers ensuring safe stopping. The suspension system handles bumps, improving comfort and stability. Finally, there's the chassis and body system, forming the overall structure. When I drive an older car, these mechanical components often require maintenance—for example, insufficient lubrication can lead to overheating failures, so regular inspections are crucial.

I pay special attention to the electrical system in cars, which involves the battery, alternator, and wiring network. The battery provides starting power, the alternator charges while driving, and the wires connect the headlights, dashboard, and various sensors. Modern cars have additional Electronic Control Units (ECUs) to manage engine operation, as well as ABS anti-lock braking systems. Entertainment systems like radios also rely on circuits. I've personally encountered several instances where a weak battery caused starting difficulties, requiring checks on fuses or replacement of the battery. Aging wires are prone to short circuits, so caution is needed during repairs to avoid damaging other components.

What Causes the Engine Fault Light to Illuminate During Self-Check in the Nissan X-Trail?

The engine fault light in the Nissan X-Trail may illuminate due to the following 7 main reasons: Sensor Malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or signal interruption occurs, the vehicle's ECU cannot accurately obtain engine data, triggering the engine fault light. Fuel or Oil Quality Issues: If fuel or engine oil is not added as per the manufacturer's requirements, it may cause engine wear, leading to the fault light illuminating. Poor Combustion of Air-Fuel Mixture: Poor combustion can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues like spark plug failure, ignition coil failure, fuel pump failure, or clogged fuel lines can cause poor combustion. Turbocharging Problems: The intake boost pipeline or turbocharger can also trigger the engine fault light. The most common issue is turbocharger damage, accompanied by symptoms like oil leaks, high oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If the vehicle's intake system is compromised, it may lead to clogged engine pipelines, and in severe cases, the engine fault light will illuminate. A dirty air filter that isn't cleaned regularly can cause intake issues. Exhaust Problems: Exhaust faults can also cause the engine fault light to illuminate. Common causes include rear oxygen sensor failure, catalytic converter issues, exhaust camshaft and bearing failure, with the catalytic converter being the most frequent problem. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily lead to catalytic converter failure. Anti-Theft System Malfunction: If the vehicle's electronic anti-theft system fails or if the anti-theft controller does not match the engine's electronic controller, the anti-theft system can prevent the engine from operating normally, causing the engine fault light to illuminate. If the engine fault light illuminates, follow these steps: First, check if the engine is running normally, looking for signs like shaking or black smoke. If such issues are present, avoid restarting the engine. Note: Do not restart the engine if the light is red. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The vehicle will perform a self-check upon powering up. Wait for 5-10 seconds to see if the fault light turns off. If the fault light remains on, visit a service station as soon as possible. The service station can use a portable diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.

How Long Does It Generally Take for a Car to Be Scrapped?

The scrapping periods for non-commercial vehicles and commercial vehicles are different, as detailed below: Scrapping regulations for non-commercial vehicles: For household 5-seat cars and 7-seat SUVs, as well as small and micro non-commercial vehicles, there is no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping process. In addition to the above vehicles, small and micro non-commercial passenger vehicles, large non-commercial cars, and wheeled special machinery vehicles also have no usage period limit. Common scrapping regulations for commercial vehicles: Small and micro taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles have a scrapping period of 10 years, and large taxi passenger vehicles have a scrapping period of 12 years. Public transport passenger vehicles have a scrapping period of 13 years, other small and micro commercial passenger vehicles have a scrapping period of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping period of 15 years. Micro commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out the "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" and affix the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, after inspection by the vehicle inspection office and confirmation that they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Modification Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the vehicle inspection office for verification and signature. The license plates will be reclaimed, and the scrapping registration will be processed according to regulations. Special notes: According to Article 30 of the "Regulations on Vehicle Registration", if the vehicle is damaged and cannot be driven back to the registration location, the owner can submit the vehicle for scrapping to a local vehicle recycling company. Commercial vehicles converted to non-commercial use must still be scrapped according to the original commercial vehicle scrapping period. According to Article 43 of the "Regulations on Vehicle Registration", after completing the vehicle transfer or deregistration, the original owner can apply to use the original license plate number when registering a new vehicle. The following conditions must be met: (1) The application must be submitted within six months after the transfer or deregistration; (2) The owner must have owned the original vehicle for more than three years.

What is the voltage of the ABS sensor connector?

ABS sensor connector input voltage is 5 to 8V, output voltage is 650 to 850mV. The measurement method is to observe the voltage value displayed on the multimeter at the moment the ignition switch is turned on. As long as the voltage value changes, it indicates that the circuit connection is normal. Symptoms of a faulty ABS sensor include: 1. Inability to prevent wheel lock-up during emergency braking, posing a safety hazard; 2. The ABS warning light will illuminate, and the brake pads may not reset. The ABS system has a self-diagnostic function that monitors the system's operation. Once a fault that affects the normal operation of the system is detected, the ABS will automatically shut down, the ABS warning light will turn on, and a warning signal will be sent to the driver.
