BODY CONTROL SYSTEM : System Description
INFOID:0000000006014870
OUTLINE
• BCM (Body Control Module) controls various electrical components.It receives the information required from
CAN communication and the signals received from each switch and sensor.
• BCM has a combination switch reading function for reading the status of combination switches (light, turn
signal, wiper and washer) in addition to functions for controlling the operation of various electrical compo-
nents. It also has a signal transmission function, for other systems, and a power consumption control func-
tion that reduces the power consumption with the ignition switch OFF.
• BCM is equipped with a diagnosis function that operates with CONSULT-III and allows for various settings to
be changed.

REAR WIPER MOTOR PROTECTION
BCM detects the rear wiper stopping position according to the rear wiper auto stop signal.
When the rear wiper auto stop signal does not change more than 5 seconds while driving the rear wiper, BCM
stops power supply to protect the rear wiper motor.
Condition of cancellation
1.
Pass more than 1 minute after the rear wiper stop.
2.
Turn rear wiper switch OFF.
3.
Operate the rear wiper switch or rear washer switch.

INFOID:0000000006032441
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.

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.

SYSTEM
- 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 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 (TAIL LAMP switch) is turned ON
• The circuit between OUTPUT 4 and INPUT 5 is formed when the TAIL LAMP switch is turned ON.
• BCM detects the combination switch status signal “5D” when the signal of OUTPUT 4 is input to INPUT 5.
• BCM judges that the TAIL LAMP switch is ON when the signal “5D” is detected.
Example 2: When some switches (TURN RH switch, TAIL LAMP switch) are turned ON
