The Function of Car Electronic Anti-Theft Devices

Car electronic anti-theft devices function by locking the ignition and preventing vehicle startup to achieve anti-theft purposes. Once in anti-theft mode, triggered events will activate an alarm notification. The main types of electronic anti-theft systems are as follows: 1. Key-controlled type. Uses the key to lock/unlock doors while simultaneously arming/disarming the anti-theft system. 2. Remote-controlled type. The anti-theft system can remotely control door lock/unlock operations. 3. Alarm-only type. The system only sounds an alarm when theft is detected, without vehicle immobilization capability. 4. Comprehensive anti-theft system with alarm and immobilization. When theft occurs, besides audible alarms, it can cut off the starter circuit, ignition circuit or fuel system to prevent vehicle movement. 5. Electronic tracking anti-theft system. This includes satellite positioning tracking systems and two-way radio centralized monitoring systems.

What Are the Reasons Why the Car Remote Key Cannot Unlock the Door?

Possible reasons why the car remote key cannot unlock the door are as follows: 1. The car key battery is dead, causing the door to not open. If the remote control flashes when pressed, it indicates that the issue is not with the key, and the mechanical key can be used to open the door first. 2. There is strong interference around, preventing the car remote from unlocking the door. Keyless start cars have sensors inside that can start the engine as long as the key is detected. 3. It could also be due to poor circuit contact, making the door unable to open. This is a rare occurrence, and in such cases, placing the key close to the sensor should allow the car to start. 4. The car battery is dead, so the door cannot be opened. You can find another car with a working battery, connect both batteries with jumper cables, and let the car charge for a few minutes before trying again.

Why does the EA888 engine oil pressure switch function fail?

Reasons for the failure of the EA888 engine oil pressure switch function: It may be due to poor contact switch operation or grounding of the wiring harness. Symptoms of the fault: After the engine starts and the oil pressure reaches the specified value, the indicator light remains on. Solution: Promptly visit a repair shop for servicing to avoid affecting driving safety. The following is relevant information: 1. The engine oil pressure switch is used to detect whether there is oil pressure in the engine. It consists of a diaphragm, spring, and contacts. The oil pressure indicator light is installed in the combination instrument panel, and the pressure switch is installed on the engine's lubrication circuit. 2. Inside the pressure switch, there is a diaphragm that moves under oil pressure and contacts that operate under oil pressure. When the oil pressure is below the specified value, the diaphragm does not have the force to push the spring, the contacts close, and the indicator light turns on. When the oil pressure is above the specified value, the diaphragm pushes the spring, the contacts separate, and the indicator light turns off, indicating to the driver that the oil pressure has reached the specified value. Under normal conditions, the contact operating pressure ranges between 30~50 kPa.

Which is better, combined injection or direct injection?

The differences between combined injection and direct injection are as follows: 1. Different engine systems. The most critical system of a direct injection engine is the high-pressure fuel injection system, which mainly consists of four parts: the engine control module (ECM), high-pressure fuel rail, high-pressure fuel pump, and fuel injector. A combined injection engine has both direct injection and manifold injection systems. 2. Different fuel injection methods. Direct injection is a technology that directly injects fuel into the cylinder to mix with the intake air, while combined injection combines the advantages of manifold injection and direct injection. Under low-load conditions, the manifold injector sprays fuel during the cylinder's intake stroke, allowing the mixture to enter the cylinder, and then the cylinder injector sprays fuel during the compression stroke to achieve stratified combustion. Under high-load conditions, only direct injection is performed during the compression stroke, thereby improving the engine's efficiency and avoiding the emission issues caused by excessive oxygen under low-load conditions in direct injection engines. 3. Different costs. Since a combined injection engine integrates both direct injection and manifold injection systems, with two sets of fuel pumps and fuel supply pipelines, its cost is significantly higher than that of a direct injection engine.

Is the first maintenance of a car free?

The first maintenance of a car is not free nationwide. The first maintenance is a method to attract customers. Offering too many cash discounts or too many gift packages to consumers will affect profits, while offering the first maintenance can not only attract customers but also maximize profits. Conditions for the first maintenance: The free first maintenance is conditional. For example, the engine oil and filter box are indeed free, but they are low-grade engine oil. If you want to upgrade to high-grade engine oil, you need to pay the price difference. In addition, some parts such as air filters and even miscellaneous services may require the car owner to pay out of pocket. Items for the first maintenance: Replace engine oil and oil filter, clean the air filter; check whether the coolant level of the car is in a normal state; check whether the car's brakes and chassis parts are scratched; check whether the power steering fluid level is normal and whether there is any oil leakage at each oil pipe interface; check the aging and tightness of the generator, air conditioner, water pump, and belt; check the tire pressure and wear condition. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing.

What to Do If the Car Paint Gets Scratched Off?

Solutions for scratched-off car paint are as follows: 1. Assess the extent of the paint damage, the location of the scratch, and the size of the affected area. 2. If it's just a minor scratch and the primer is not damaged, you can use a touch-up pen to fix it. 3. If the scratched area is not large, you can also purchase spray paint and handle it yourself. 4. If the paint damage is severe, you need to go to a 4S shop for sanding and polishing, apply primer, and then perform a full repaint. Reasons for car paint getting scratched off are as follows: 1. Scratches or collisions during driving, leading to paint loss. 2. Human factors or scratches from hard objects, causing paint loss. 3. Poor quality of the car body paint, leading to spontaneous peeling. 4. Lack of proper car maintenance, prolonged exposure to sun and rain, causing corrosion of the car body paint.
