What does BCM mean in cars?

[StKyle]

Automotive BCM refers to the Body Control Module, which primarily controls the electrical components of the vehicle body, such as the vehicle's lighting system, wipers, washers, door locks, power windows, sunroof, power mirrors, and remote control. The application of the body controller enables modern vehicles to achieve increasingly complex functions, and with the development of computer systems and chip processing capabilities, current body control systems are gradually moving towards intelligent development. The following is an introduction to the functions of the BCM: Receiving Information: Receives input information from sensors and converts it into signals that the microprocessor can process. Output Commands: Converts weak signals into executable commands after outputting execution commands and corrects after outputting fault information. Comparing Information: Performs calculations and analysis to determine the data for execution commands based on information parameters and compares the input information with standard values. It stores, calculates, analyzes, and processes information, analyzes the programs used for output values, stores the characteristic parameters of the vehicle model, data during calculations, and fault information.
