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.

System DescriptionINFOID:0000000003809587
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 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.
Operation Example
In the following operation example, the combination of the status signals of the combination switch is replaced
as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.
Example 1: When a switch (TURN RH switch) is turned ON
INPUT 4 — INT VOLUME 3 AUTO LIGHT — TAIL LAMP
INPUT 5 INT VOLUME 2 — RR FOG FR FOG —System OUTPUT 1 OUTPUT 2 OUTPUT 3 OUTPUT 4 OUTPUT 5
