Body Control Module (BCM)
The BCM, a master unit of the multiplex control system, has communication and control capabilities. The BCM consists of a microprocessor and memory and communication LSI sections. The BCM processes data signals received from the LCU's and sends electrical load data signals to each LCU.
NOTE:
The A/C auto amplifier, if equipped, is built into the BCM. BCM connectors are located on the front side of BCM. DO NOT confuse these connectors with A/C auto amplifier connectors, located on rear side of BCM.
