SYSTEM DESCRIPTION

BODY CONTROL SYSTEM

System Description

INFOID:0000000005518265

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.

System Description

INFOID:0000000005681335

OUTLINE

• BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the

status of each switch.

• BCM is a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a

maximum of 20 switch status.

COMBINATION SWITCH READING SYSTEM

NOTE:

Headlamp has a dual system switch.

COMBINATION SWITCH READING FUNCTION

Description

• BCM reads the status of the combination switch at 10 ms interval normally.

NOTE:
BCM reads the status of the combination switch at 60 ms interval when BCM is controlled at low power con-
sumption mode.

• BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5 

 4 

 3 

 2 

 1.

- The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of

the transistor on OUTPUT side if any (1 or more) switches are ON.

- It reads this change of the voltage as the status signal of the combination switch.
