Body Control Module (BCM)
The BCM, a master unit of the multiplex control system, has communication and control capabilities. The BCM consists of microprocessor, memory and communication LSI sections. The BCM processes data signals received from the LCUs and sends electrical load data signals to each LCU.
NOTE:
The 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.
