BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
lWith ignition switch ON, CAN communicates with other control units normally.
lControl by BCM is being operated properly.
lWhen ignition switch is OFF, switching to sleep mode is possible.
lEven when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status
lThis status shuts down CAN communication when ignition switch is turned OFF.
lIt transmits sleep request signal to IPDM E/R and combination meter.
lTwo seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status
lWith ignition switch OFF, CAN communication is not active.
lWith ignition switch OFF, control performed only by BCM is active.
lThree seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status
lBCM is activated with low current consumption mode.
lCAN communication is not active.
lWhen CAN communication operation is detected, it switches to CAN communication status.
lWhen a state of the following switches changes, it switches to CAN communication state:
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH) (double cab)
–Rear door switch (driver side, passenger side) No.1 (king cab)
–Rear door switch (driver side, passenger side) No.2 (king cab)
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Door lock assembly LH (key cylinder switch)
lWhen control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
lStatus of combination switch reading function is changed.

Door lock indicator timer
Door lock indicator timer is designed to reacts and shut down the indicator. The default timer values are 1
minute and 30 minutes.
lWhen the lock operation is activated by keyfob or auto door lock (for further details, refer toBL-92, "Auto
Re-lock Function"), then the illuminate time is set to 1 minute.
lWhen the lock operation is activated by door lock/unlock switch, then the timer is set to 30 minutes.
NOTE:
When the 30 minutes timer is active and ignition switch is turned ON, the indicator illuminate for perma-
nently, unless ignition switch is turned OFF then timer will be reset back to 30 minutes.
CAN Communication System DescriptionEIS00D7T
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

OUTLINE
Power door lock systems with super lock function provides a higher anti-theft performance than conventional
power door lock systems. The super lock system is controlled by BCM (Body Control Module).
Pressing LOCK button on key fob once will lock all doors and activate super lock simultaneously.
When super lock is set, all doors cannot be opened from inside.
Pressing UNLOCK button once on key fob will unlock driver side door (unlock all doors if anti-hijack system is
disabled and during this state, super lock is still active). Second press on the UNLOCK button within 5 second
from the first will unlock all doors and release super lock simultaneously.
Functions Available By Operating the Door Lock/Unlock Switch
lOperating the door lock/unlock switch in the control panel will activate all doors actuator to lock or unlock.
If any doors are opened (except the driver side) during operating the door lock/unlock switch in lock direc-
tion, the door lock actuators will not response. Unlock via the interior door handles and door lock/unlock
switch is always possible.
lOperating the door lock/unlock switch to “LOCK” will lock the vehicle even while driver side door is
opened.
OPERATION
Set Super Lock Conditions
lWhen all these following conditions are met, BCM receives lock signal from key fob.
–All doors are closed.
–Key is out of the ignition key cylinder.
Release Super Lock Conditions
lBCM unit receives a valid unlock signal from key fob.
lIgnition switch is turned ON (door lock/unlock switch will remain its state, super lock is released).
NOTE:
Door lock/unlock switch is incapable of overriding super lock.

accomplish, during this state, if any door is open, the indicator will turn OFF.
Door Lock Indicator Timer
Door lock indicator timer is designed to reacts and shut down the indicator. The default timer values are 1
minute and 30 minutes.
lWhen the lock operation is activated by keyfob or auto door lock (for further details refer toBL-92, "Auto
Re-lock Function"), then the illuminate time is set to 1 minute.
lWhen the lock operation is activated by door lock/unlock switch, then the timer is set to 30 minutes.
NOTE:
When the 30 minutes timer is active and ignition switch is turned ON, then the indicator illuminate for per-
manently unless ignition switch is turned OFF then timer will be reset back to 30 minutes.

OPERATING PROCEDURE
Power Door Lock Operation
BCM receives a LOCK signal from keyfob. BCM locks all doors with input of LOCK signal from keyfob.
When an UNLOCK signal is sent from keyfob once, driver's door is unlocked.
Then, if an UNLOCK signal is sent from keyfob again within 5 seconds, all doors are unlocked.
Hazard Reminder
When the doors are locked or unlocked by keyfob, power is supplied to hazard warning lamp.
Hazard reminder does not operate if any door switches are ON (any doors are OPEN).
How to change hazard and horn reminder mode
Hazard and horn reminder can be changed using “WORK SUPPORT” mode in “MULTI ANSWER BACK SET”.
Refer toBL-102, "
CONSULT-II Function (BCM)".
