DOOR LOCK FUNCTION

Functions Available by Operating the Door Lock and Unlock Switches on Driver Door and Passenger Door

• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors are

locked, back door opener switch is disabled, and mechanical glass hatch switch is disabled.

• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors are

unlocked, back door opener switch is enabled, and mechanical glass hatch switch is enabled.

• Provided the passenger front door is unlocked, when the back door opener switch is pressed, the BCM ter-

minal 30 receives signal from the back door opener switch terminal 1, through terminal 2, to front door lock

assembly RH (door unlock sensor) terminal 1, through terminal 3, to ground.

• When the BCM receives the signal, if the back door operating enable conditions are met, it sends a signal

through terminal 53 to open the back door latch.

Functions Available by Operating the Key Cylinder Switch on Driver Door

• Interlocked with the locking operation of door key cylinder, door lock actuators of all doors are locked, back

door opener switch is disabled, and mechanical glass hatch switch is disabled.

Selective Unlock Operation

• When door key cylinder is unlocked, door lock actuator driver side is unlocked.

• When door key cylinder is unlocked for the second time within 5 seconds after the first operation, door lock

actuators on all doors are unlocked.

Select unlock operation mode can be changed using DOOR LOCK-UNLOCK SET mode in “WORK SUP-

PORT”. Refer to

REMOTE KEYLESS ENTRY : System Diagram

INFOID:0000000005260027

REMOTE KEYLESS ENTRY : System Description

INFOID:0000000005260028

OPERATED PROCEDURE

• When the keyfob is operated, the signal from the keyfob is sent and the remote keyless entry receiver

receives the signal and sends it to the BCM. The BCM only locks/unlocks the doors if the ID number

matches. (Remote control entry functions)

• Using the keyfob, the transmitter sends radio waves to the remote keyless entry receiver, which then sends

the received waves to the BCM. Only if the ID number matches does the BCM lock/unlock the doors.

(Remote control door function)

• Unless the key is inserted into the ignition key cylinder or one of the doors is opened within 1 minute after the

UNLOCK switch on the keyfob is pressed, all the doors are automatically locked. (Auto lock function)

• When a door is locked or unlocked, the vehicle turn signal lamps flash and the horn sounds to verify opera-

tion. (Active check function)

• When the key is in the ignition key cylinder (when the key switch is ON) and one of the doors is open, the

door lock function does not work even when the door lock is operated with the keyfob.

• Keyfob ID set up is available.

• If a keyfob is lost, a new keyfob can be set up. A maximum of 5 IDs can be set up simultaneously.

REMOTE CONTROL ENTRY FUNCTIONS

• When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote key-

less entry receiver.

• The received signal is sent to the BCM and compared with the registered ID number.

• If the ID number matches, the BCM sends the lock/unlock signal to each door lock actuator.

• When the door lock actuators receive this signal, each operates to lock/unlock its door.

• BCM locks all doors with input of LOCK signal from keyfob.

• When an UNLOCK signal is sent from keyfob once, driver's door will be unlocked.

• Then, if an UNLOCK signal is sent from keyfob again within 5 seconds, all other doors will be unlocked.

REMOTE CONTROL ENTRY OPERATION CONDITIONS

AUTO RELOCK FUNCTION

Operation Description

• Unless the key is inserted into the ignition key cylinder, one of the doors is opened, or the keyfob is operated

within 1 minute after a door lock is unlocked by keyfob operation, all the doors are automatically locked.

The 1 minute timer count is executed by the BCM and after 1 minute, the BCM sends the lock signal to all

doors.

Lock operations are the same as for the remote control entry function.

ACTIVE CHECK FUNCTION

Operation Description

When a door is locked or unlocked by keyfob operation, the vehicle turn signals flash and the horn sounds to

verify operation.

• When a button on the keyfob is operated, the signal is sent from the remote controller and received by the

keyless remote entry receiver.

• The received signal is sent to the BCM and compared with the registered ID number.

• If the ID number matches, the BCM uses communication to send the turn signal flashing and horn signal to

the IPDM E/R.

• The IPDM E/R flashes the turn signal lamps and sounds the horn for each keyfob operation.

Operating function of hazard and horn reminder

HAZARD AND HORN REMINDER

BCM output to IPDM E/R for horn reminder signal as DATA LINE (CAN-H line and CAN-L line).

The hazard and horn reminder has C mode (horn chirp mode) and S mode (non-horn chirp mode).

How to change hazard and horn reminder mode

With CONSULT-III

Hazard and horn reminder can be changed using “WORK SUPPORT” mode in “MULTI ANSWER BACK SET".

Without CONSULT-III

Refer to Owner's Manual for instructions.

INTERIOR LAMP OPERATION

When the following input signals are both supplied:

• all door switches are in the OFF position. (when all the doors are closed);

• interior lamp switch is in DOOR position.

Remote keyless entry system turns on interior lamp and ignition keyhole illumination (for 30 seconds) with

input of UNLOCK signal from keyfob.

PANIC ALARM OPERATION

When key switch is OFF (when ignition key is not inserted in key cylinder), remote keyless entry system turns

on and off horn and headlamp intermittently with input of PANIC ALARM signal from keyfob.

The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.

KEYLESS POWER WINDOW DOWN (OPEN) OPERATION

When keyfob unlock switch is turned ON with ignition switch OFF, and the switch is detected to be ON contin-

uously for more than 3 second, the driver's door and passenger's door power windows are simultaneously

opened.

Power window is operated to open and the operation continues as long as the keyfob unlock switch is

pressed.
