BODY CONTROL SYSTEM : System DescriptionINFOID:0000000012432363
OUTLINE
• BCM (Body Control Module) controls the various elec
trical components. It inputs the information required to
the control from CAN communication and the signal received from each switch and sensor.
• BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power saving con-
trol function that reduces the power c onsumption with the ignition switch OFF.
• BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT and various set- tings.

COMBINATION SWITCH READING FUNCTION
Description
• BCM reads the status of the combinat
ion 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 si de 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.

SYSTEM
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 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.
• 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 wake-up conditions are ful- filled. It changes from the low power consumption mode to the normal mode.
• Each unit starts the transmission of CAN communica tion with the sleep wake up signal. Each unit transmits
the wake up signal to BCM via CAN communication to report the CAN communication 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-136, "
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-125, "
Work Procedure".

TRANSIT MODE CONTROL SYST EM : System Description
INFOID:0000000012432369
DESCRIPTION
Transit mode is a BCM function that disables several elec trical 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.
To cancel transit mode, refer to BCS-126, "
Work Procedure".
Status Symptom
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).
