DOOR LOCK FUNCTION
Door Lock and Unlock Switch
• The door lock and unlock switch (driver side) is built into power window main switch.
• The door lock and unlock switch (passenger side) is built into front power window switch (passenger side).
• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors are
locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors are
unlocked.
Door Key Cylinder Switch
• With the mechanical key inserted in the door key cylinder on driver side, turning it to lock position locks door
lock actuators of all doors.
• With the mechanical key inserted in the door key cylinder on driver side, turning it to unlock position once
unlocks the driver side door, turning it to unlock pos ition again within 60 seconds after the first unlock opera-
tion unlocks all of the other door act uators. (SELECTIVE UNLOCK OPERATION)
Selective unlock operation mode can be changed using CONSULT.
Refer to BCS-15, "DOOR LOCK : CONSULT Function (BCM - DOOR LOCK)"
.
DOOR KEY CYLINDER SWIT CH POWER WINDOW FUNCTION
Driver side door key cylinder LOCK/UNLOCK operat ion can activate power window. Refer to PWC-72, "Sys-
tem Description".
IGNITION POSITION WARNING FUNCTION
When door lock and unlock switch are operated while driv er side door is open and ignition position is ACC or
ON, door locks once but immediately unlocks.
INTERIOR ROOM LAMP CONTROL FUNCTION
Interior room lamp is controlled according to door lock/unlock state, refer to INL-7, "System Description".
AUTOMATIC DOOR LOCK/UNLOCK FUNCTION (LOCK OPERATION)
The interlock door lock function is the function that locks all doors linked with the vehicle speed or shift posi-
tion. It has 2 types as per the following items.
Vehicle Speed Sensing Auto Door Lock
All doors are locked when the vehicle speed reaches 24 km/h (15 MPH) or more.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is turned ON, all
doors are closed and the vehicle speed received from the combination meter via CAN communication
becomes 24 km/h (15 MPH) or more.

COMMON ITEM
COMMON ITEM : CONSULT Function (BCM - COMMON ITEM)INFOID:0000000009952500
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.
CAN Diag Support Mntr The result of transmit/receive diagnosis of CAN communication is displayed.
