< SYSTEM DESCRIPTION >[WITH INTELLIGENT KEY SYSTEM]
SYSTEM
• 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 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 wakeup signal. BCM is in CAN com- munication sleep mode.
• BCM is in the low power consumption mode and perform s the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
• BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions are fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the
normal mode.
• Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the com- bination meter transmits the wake up signal to BCM via CAN communication to report the CAN communica-
tion start.

DESCRIPTION
• The BCM switches the status (shipping mode or norma
l mode) by itself according to the extended storage
switch condition, and transmits the shipping mode status signal to the combination meter and each unit via
CAN communication.
• When the shipping mode function is activated, the control units will not detect DTCs.
• BCM control functions are limited in shipping mode. Refer to BCS-73, "
Description".
• When the BCM is in shipping mode, a message may be shown in the combination meter or display.
• For shipping mode cancel operation refer to BCS-61, "
Work Procedure".
TRANSIT MODE CONTROL SYSTEM
TRANSIT MODE CONTROL SYSTEM : System DescriptionINFOID:0000000012432312
DESCRIPTION
Transit mode is a BCM function that disables several el ectrical functions such as door lock/unlock by remote,
back door open by remote, panic alarm, anti-theft alarm, etc. Vehicles are shipped with the BCM in transit
mode to help prevent the battery from becoming discharged during dealer storage.
DETERMINING TRANSIT MODE STATUS
Use the table below to determine the transit mode status.
CANCELING TRANSIT MODE
NOTE:
Transit mode can only be canceled. Once transit mode has been canceled, it cannot be activated again.
AWMIA1687GB
Sta tus Sy mp tom
Transit Mode When ignition switch is turned from OFF to ON, turn signal indicators will illuminate for 1 minute.
Normal Mode (not in transit mode) When ignition switch is turned from OFF to ON,
turn signal indicators stay OFF (do not illumi-
nate).
