REMOTE KEYLESS ENTRY SYSTEM
Revision: October 20052005 QX56
NOTE:

If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A specific ID
code can be erased with CONSULT-II. However, when the ID code of a lost keyfob is not known, all con-
troller ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new
keyfobs must be re-registered.
To erase all ID codes in memory, register one ID code (keyfob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new keyfobs must be re-registered.

When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If five
ID codes are stored in memory, when an additional code is registered, only the oldest code is erased. If
less than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is
added and no ID codes are erased.

If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry” for each new keyfob.

Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID code
will be erased.

Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: October 20052005 QX56
System DescriptionEIS008QM
DESCRIPTION
Operation Flow

Setting the vehicle security system
Initial condition

Ignition switch is in OFF position.
Disarmed phase

When the vehicle is being driven or when doors or glass hatch is open, the vehicle security system is set
in the disarmed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase

The vehicle security system turns into the "pre-armed" phase when hood, glass hatch and all doors are
closed and locked by keyfob. The security indicator lamp illuminates for 30 seconds, then the system
automatically shifts into the "armed" phase.
Canceling the set vehicle security system
When one of the following operations is performed, the armed phase is canceled.
1. Unlock the doors with the key or the keyfob.
2. Open the power back door with the keyfob. When the power back door is closed after opening the power
back door with the keyfob, the system returns to the armed phase.
Activating the alarm operation of the vehicle security system
Make sure the system is in the armed phase.
When one of the following operations is performed, the system sounds the horns and flashes the headlamps
for about 50 seconds.
1. Engine hood, glass hatch or any door is opened before unlocking door with key or keyfob.

2. Door is unlocked without using key or keyfob.
3. Power back door is opened without using the keyfob.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No.19, located in the fuse block (J/B)]

to combination meter (security indicator lamp) terminal 8 and

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70.

through 15A fuse [No. 22, located in the fuse block (J/B)]

to BCM terminal 57.

through 15A fuse (No. 25, located in the fuse and fusible link box)

to horn relay terminal 2.

through 20A fuse (No. 52, located in the IPDM E/R) and

through 20A fuse (No. 53, located in the IPDM E/R),

to IPDM E/R internal CPU.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 4, located in the fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 67

through body grounds M57, M61 and M79 and

to IPDM E/R terminals 38 and 59

through body ground E9, E15 and E24.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and glass hatch.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and glass hatch
are closed and the doors are locked.
When a door is open, BCM terminal 12, 13, 42, 47 or 48 receives a ground signal from each door switch.
When front door LH is unlocked, BCM terminal 22 receives a signal from terminal 14 of main power window
and door lock/unlock switch.
When front door RH is unlocked, BCM terminal 22 receives a signal from terminal 16 of power window and
door lock/unlock switch RH or the rear power window switch LH or RH.
When the back door is open, BCM terminal 43 receives a ground signal

from terminal 7 of the back door latch (door ajar switch)

through back door latch terminal 8

through body grounds B7 and B19.
When the glass hatch is open, BCM terminal 42 receives a ground signal

from terminal + of the glass hatch ajar switch

through glass hatch ajar switch case ground.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by

opening a door

opening the hood

opening the glass hatch

unlocking door without using the key or keyfob.
The vehicle security system will be triggered once the system is in armed phase,

when BCM receives a ground signal at terminals 12, 13, 47, 48 (door switch), terminal 42 (glass hatch ajar
switch) or terminal 43 [back door latch (door ajar switch)], or IPDM E/R terminal 41 (hood switch) receives
a ground signal.
Power is supplied at all times

Revision: October 20052005 QX56

to horn relay terminal 2

through 15A fuse (No. 25, located in fuse and fusible link box).
When the vehicle security system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to headlamp high relay and

to horn relay terminal 1.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door must be unlocked with the key or keyfob.
When the key is used to unlock the front door LH, BCM terminal 22 receives signal

from terminal 14 of the main power window and door lock/unlock switch.
When the BCM receives this signal or unlock signal from keyfob, the vehicle security system is deactivated.
(Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the remote keyless entry system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to headlamp high relay and

to horn relay terminal 1.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.

INPUT SIGNAL CHECK MODE
Input signal check mode allows testing of switch input signal to the back door control unit.
To activate input signal check mode on the automatic back door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T selector lever in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start
engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 seconds.
8. Release the back door handle switch.
9. Within 8 seconds of the back door warning chime sounding, press and hold the power liftgate switch.
10. After approximately 5 seconds, the back door warning chime will sound for 1 second.
11. Release the power liftgate switch.
12. The input signal check mode is now initialized.
The input signal check mode can test the following inputs. The back door warning chime will sound for approx-
imately 0.5 seconds each time a switch signal input occurs. Use this test when one of these inputs is not
responding during normal automatic back door operation.
*Back door warning chime should sound as soon as vehicle moves.
Turn ignition switch OFF to end input signal check mode.
OPERATING CHECK MODE
Operating check mode allows self-diagnosis of the automatic back door system.
