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 (OUTPU T 1 - 5) and 5 input terminals (INPUT 1 - 5) and reads
a maximum of 20 switch states.

• The circuits between OUTPUT 1 and INPUT 5 and bet
ween OUTPUT 4 and INPUT 5 are formed when the
TURN RH switch and TAIL LAMP switch are turned ON.
• BCM detects the combination switch status signal “5AD” when the signals of OUTPUT 1 and OUTPUT 4 are
input to INPUT 5.
• BCM judges that the TURN RH switch and TAIL LAMP switch are ON when the signal “5AD” is detected.
WIPER INTERMITTENT DIAL POSITION SETTING
BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2, and 3 switches.

POWER CONSUMPTION CONTROL SY STEM : System DescriptionINFOID:0000000009461995
OUTLINE
• BCM incorporates a power saving control function t hat reduces the power consumption according to the
vehicle status.
• BCM switches the status (control mode) by itself wit h the power saving control function. It performs the sleep
request to each unit (IPDM E/R and combination mete r) that operates with the ignition switch OFF.
Normal mode (wake-up)
- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)
- CAN transmission is stopped
- Control with BCM only is operating
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the follo wing operation in the low power consumption mode.
• The reading interval of each switch changes from 10 ms interval to 60 ms interval.
Sleep mode activation
Signal name Input Output Description
• Ignition switch ON signal
• Ignition switch signal Engine switch (push switch) IPDM E/R (CAN) Inputs the push-button ignition
switch (push switch) signal and
transmits the ignition switch sta-
tus judged with BCM via CAN
communication.
Door switch signal Any door switch • Combination meter (CAN)
• IPDM E/R (CAN) Inputs the door switch signal
and transmits it via CAN com-
munication.
