BODY CONTROL SYSTEM : System DescriptionINFOID:0000000006274789
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 fo r 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 c onsumption with the ignition switch OFF.
BCM is equipped with the diagnosis function that perfo rms the diagnosis with CONSULT-III and various set-
tings.

OUTLINE
BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the
status of each switch.
BCM has a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a
maximum of 20 switch status.

NOTE:

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 control mode.
BCM operates as follows and judges the status of the combination switch.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 1 → 2 → 3 → 4 → 5, and outputs
voltage waveform.
- The voltage waveform of OUTPUT corresponding to the formed circuit is input into the interface on INPUT
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 t he 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 (TAIL LAMP switch) is turned ON
OUTPUT 3 WIP VOLUME 1 RR WASHER — HEADLAMP 2 HI BEAM
OUTPUT 4 RR WIPER INT WIP VOLUME 3 AUTO LIGHT — TAIL LAMP
OUTPUT 5 WIP VOLUME 2 RR WIPER ON RR FOG FR FOG — System INPUT 1 INPUT 2 INPUT 3 INPUT 4 INPUT 5
