POWER CONSUMPTION CONTROL SYSTEM
POWER CONSUMPTION CONTROL SYSTEM : System Diagram
INFOID:0000000012200694
POWER CONSUMPTION CONTROL SYSTEM : System Description
INFOID:0000000012200695
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, combination meter and multi display unit) 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 the each switches 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.
Stop lamp switch signal
Stop lamp switch
TCM (CAN)
Inputs the stop lamp switch 1
signal and stop lamp switch 2
signal, and transmits it via CAN
communication.
Interlock/PNP switch signal
Transmission range switch
IPDM E/R (CAN)
Inputs the P/N position signal,
and transmits the interlock/PNP
switch signal via CAN commu-
nication.

SYSTEM
• BCM is in the low power consumption mode and perform the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
NOTE:
*: Refer to
INL-8, "INTERIOR ROOM LAMP BATTERY SAVER SYSTEM : System Description"
the interior room lamp battery saver time.
Wake-up operation
• BCM transmits sleep wake up signal (wake up) to each unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
• Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans-
mit wake up signals to BCM with CAN communication to convey the start of CAN communication.
