Body Control Module (BCM)

NOTE: A/C auto amplifier (if equipped) is built into the BCM. BCM harness connectors are located on the front side of BCM. DO NOT confuse these connectors with A/C auto amplifier harness connectors, located on rear side of BCM.

BCM, a master unit of the multiplex control system, has communication and control capabilities via multiplex data lines. BCM consists of microprocessor, memory and communication LSI sections. BCM processes data signals received from the LCUs and sends command signals to each LCU.
