BODY CONTROL SYSTEM

System Description

INFOID:0000000000963861

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.
