When the key is inserted in the ignition cylinder (key switch), power is supplied

●

to BCM terminal 37

●

through key switch terminals 1 and 2

●

When the front door switch LH is ON (door is OPEN), ground is supplied

●

to BCM terminal 47

●

through front door switch LH terminal 2

●

through front door switch LH case ground.

When the front door switch RH is ON (door is OPEN), ground is supplied

●

●

through front door switch RH case ground.

When the rear door switch LH is ON (door is OPEN), ground is supplied

Keyfob signal is inputted to BCM from the remote keyless entry receiver.
The remote keyless entry system controls operation of the

●

power door lock

●

interior lamp and ignition keyhole illumination

●

panic alarm

●

hazard and horn reminder

●

auto door lock operation

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)

REMOTE KEYLESS ENTRY SYSTEM

BL-41

2007 Pathfinder

●

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 oper-
ation. (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

Operation Description

●

When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote
keyless 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 Lock Function

Operation Description

●

Unless the key is inserted into the ignition key cylinder, one of the doors is opened, or the keyfob is oper-
ated 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.

NOTE:
On vehicles with NAVI, this time can be adjusted via the display. Refer to Owner's Manual for instructions.

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-II

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

Without CONSULT-II

Refer to Owner's Manual for instructions.

Interior Lamp and Ignition Keyhole Illumination 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.
For detailed description, refer to

LT-110, "ROOM LAMP TIMER OPERATION"

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.
