BMW airbag computer is installed under the sub-instrument panel, and it can be found by removing the sub-instrument panel. Functions of the airbag computer: The automotive airbag computer serves as the control center of the airbag system. Its role is to receive signals from collision sensors and other sensors, determine whether to ignite and inflate the airbag, and perform self-diagnosis of system faults. The airbag computer also continuously monitors and tests critical circuit components such as sensor circuits, ignition circuits, backup power circuits, SRS indicator circuits, and driver circuits. The test results are displayed via the SRS indicator and fault codes stored in the memory, meaning the SRS indicator on the dashboard directly provides the driver with status information about the airbag system. Components of the airbag computer: Collision sensors, EEPROM memory chips, squib driver integrated circuits, and microprocessors. Additionally, when the automotive airbag computer malfunctions, the status information and fault codes stored in its memory can be retrieved using specialized equipment or through specific methods via the serial communication interface for testing and inspection.

What is the function of engine start-stop?

The function of engine start-stop is: 1. The engine can automatically shut off, reducing fuel consumption and emissions; 2. After the engine shuts off, the power supply can replace the belt pulley to provide operating power for the engine cooling fan and in-car air conditioning. The functions of the engine are: 1. To fully burn the fuel input into the cylinder and generate power; 2. To determine the vehicle's power, fuel economy, stability, and environmental friendliness. The precautions for engine start-stop are: 1. Quickly shift to P gear when the engine shuts off and release the brake; 2. Reduce current consumption; 3. Do not repeatedly press the brake when the engine is off; 4. Do not activate the automatic start-stop system during low-speed parking or when using the air conditioning; 5. Turn off the automatic start-stop when driving through water.

Why does the car lose power when the water temperature is high?

High water temperature in a car can cause the engine to overheat and result in abnormal heat dissipation. Here is some relevant information about the radiator: 1. Concept: The car radiator, also known as a heat exchanger, is a key component of the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, thereby regulating the temperature. It is an integral part of the car engine. 2. Working principle: The radiator is a crucial component of a water-cooled engine. As an essential part of the engine's cooling circuit, it absorbs heat from the cylinder block to prevent engine overheating. Due to the high specific heat capacity of water, the temperature rise after absorbing heat from the cylinder block is not significant, so the engine's heat is managed through the liquid cooling circuit of the coolant.
