System Description

BCM (Body Control Module):

BCM (Body Control Module)
The BCM, which is a master unit of the LAN (Local Area Network) system, consists of microprocessor, memory and communication LSI sections and has communication and control functions. It receives data signals from the LCUs and sends electrical load data signals to them.

The BCM is described as a "control assembly (for LAN)" in the Parts Catalog.

LCU (Local Control Unit):

LCU (Local Control Unit)
The LCU, which is a slave unit of the BCM, has only a communication function and consists of communication LSI and input/output interface circuits. It receives a data signal from the BCM, controls the ON/OFF operation of electrical loads and the sleep operation, as well as sends a switch signal to the BCM.
