BODY CONTROL SYSTEM
System DescriptionINFOID:0000000003809584
OUTLINE
 BCM (Body Control Module) controls the various electrical components. It inputs the information required to
the control from CAN communication and the signal received from each switch and sensor.
 BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power saving con-
trol function that reduces the power consumption with the ignition switch OFF.
 BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT-III and various set-
tings.
