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
Combination switch INPUT-OUTPUT system list
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.
