Combination switch INPUT-OUTPUT system list
COMBINATION SWITCH READING FUNCTION
Description
• BCM reads the status of the combination switch at 10 ms intervals normally.
NOTE:
BCM reads the status of the combination switch at 60 ms intervals when BCM is controlled at low power
consumption 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 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) is turned ON
• The circuit between OUTPUT 3 and INPUT 5 is formed when the TURN RH switch is turned ON.
• BCM detects the combination switch status signal “5C” when the signal of OUTPUT 3 is input to INPUT 5.
• BCM judges that the TURN RH switch is ON when the signal “5C” is detected.
Example 2: When some switches (FR FOG, TURN RH) are turned ON

SYSTEM
• The circuits between OUTPUT 1 and INPUT 5 and between OUTPUT 3 and INPUT 5 are formed when the
FR FOG switch and TURN RH switch are turned ON.
• BCM detects the combination switch status signal “5AC” when the signals of OUTPUT 1 and OUTPUT 3 are
input to INPUT 5.
• BCM judges that the FR FOG switch and TURN RH switch are ON when the signal “5AC” is detected.
WIPER INTERMITTENT DIAL POSITION SETTING (FRONT WIPER INTERMITTENT OPERATION)
BCM judges the wiper intermittent dial 1 - 4 by the status of INT VOLUME 1, 2, and 3 switches.

POWER CONSUMPTION CONTROL SYSTEM
POWER CONSUMPTION CONTROL SYSTEM : System Description
INFOID:0000000011280182
SYSTEM DIAGRAM
OUTLINE
• BCM incorporates a power saving control function that reduces the power consumption according to the
vehicle status.
• BCM switches the status (control mode) by itself with the power saving control function. It performs the sleep
request to each unit (IPDM E/R and combination meter) 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 following 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
• BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-
tion.
• BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful-
filled.
• Each unit stops the transmission of CAN communication with the sleep wake-up signal. BCM is in CAN com-
munication sleep mode.

and transmits it via CAN com-
munication.
