OUTLINE

• BCM (body control module) controls various electrical components. It receives the information required from

CAN communication and the signals received from each switch and sensor.

• BCM has a combination switch reading function for reading the status of combination switches (light, turn

signal, wiper and washer) in addition to functions for controlling the operation of various electrical compo-

nents. It also has a signal transmission function for other systems, and a power consumption control function

that reduces the power consumption with the ignition switch OFF.

• BCM is equipped with a diagnosis function that operates with CONSULT and allows for various settings to

be changed.
