It monitors various engine parameters such as engine speed, temperature, air-fuel ratio, and throttle position, and adjusts engine functions accordingly. This includes controlling fuel injection, ignition timing, idle speed, and emissions systems to ensure optimal engine performance, fuel efficiency, and emissions compliance.

It acts as a centralized control unit for these systems, receiving input from various switches and sensors throughout the vehicle and sending commands to control the corresponding functions. Additionally, the BCM may also be involved in security and anti-theft systems, as well as keyless entry and remote start functionality.

TCM (Transmission Control Module):

The TCM is responsible for controlling the operation of the vehicle's transmission. It monitors various inputs such as vehicle speed, throttle position, and engine load to determine the optimal shift points and shift strategy for the transmission. The TCM also controls the engagement of the torque converter and may manage additional features such as adaptive shift logic or manual shift modes in automatic transmissions. In vehicles with manual transmissions, the TCM may be referred to as the Transmission Control Unit (TCU).
