2023 NISSAN FRONTIER ECU

The system helps deter vehicle thef t but
cannot prevent it, nor can it prevent the
thef t of interior or exterior vehicle compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your keys in the vehicle, and
always lock the vehicle when unattended.
Be aware of your surroundings, and park in
secure, well-lit areas whenever possible.
Many devices offering additional protec-
tion, such as component locks, identifica-
tion markers, and tracking systems, are
available at auto supply stores and spe-
cialty shops. A NISSAN dealer may also offer
such equipment. Check with your insur-
ance company to see if you may be eligible
for discounts for various thef t protection
features.
How to arm the vehicle security
system
1. Close all windows.(The system can be
armed even if the windows are open.)
2. Remove the Intelligent Key from the vehicle.
3. Close all doors. Lock all doors. The doors can be locked with the power door lock
switch (if the door is opened, locked and
then closed) or with the key fob. Key fob operation:
• Press the
button on the key fob. All
doors lock. The hazard lights flash twice
and the horn beeps once to indicate all
doors are locked.
• When the
button is pressed with all
doors locked, the hazard lights flash twice
and the horn beeps once as a reminder
that the doors are already locked.
The horn may or may not beep.
4. Confirm that the
indicator light
comes on. Theindicator light
stays on for about 30 seconds. The ve-
hicle security system is now pre-armed.
Af ter about 30 seconds the vehicle se-
curity system automatically shif ts into
the armed phase. The
indicator
light begins to flash once every 3 sec-
onds. If, during the 30-second pre-arm
time period, the driver's door is unlocked
by the key fob or the ignition switch is
placed in ACC or ON position, the system
will not arm.
• If the indicator light fails to glow for a
period of time, unlock the door once
and lock it again. •
Even when the driver and/or passen-
gers are in the vehicle, the system will
arm with all doors closed and locked
with the ignition switch placed in the
OFF position.
Vehicle security system activation
The vehicle security system will give the
following alarm:
• The headlights blink and the horn sounds intermittently.
• The alarm automatically turns off af ter a period of time. However, the alarm reacti-
vates if the vehicle is tampered with
again. The alarm can be shut off by un-
locking the driver's door by pressing the
button on the key fob.
The alarm is activated by:
• Opening a door without using the key fob (even if the door is unlocked by using the
inside lock knob or the power door lock
switch).
How to stop an activated alarm
The alarm stops only by pressing thebutton on the key fob.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of a registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:
1.
Leave the ignition switch placed in the ON
position for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. FCC Notice:

CARGO LIGHT
The cargo light on the overhead trim has a
three-position switch. To operate, push the
switch to the desired position.
ON: The light is illuminated.
DOOR: The light illuminates when the rear
doors are opened. The light turns off when
the rear doors are closed.
OFF: The light does not illuminate regard-
less of door position or lock status.
CAUTION
Do not use for extended periods of time
with the engine stopped. This could re-
sult in a discharged battery. The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-
held transmitters into one built-in device.
HomeLink® Universal Transceiver:
• Will operate most Radio Frequency (RF)
devices such as garage doors, gates,
home and office lighting, entry door locks
and security systems.
• Is powered by your vehicle's battery. No separate batteries are required. If the
vehicle's battery is discharged or is dis-
connected, HomeLink® will retain all
programming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming
procedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased for
security purposes. For additional infor-
mation, see “Programming HomeLink®”
(P. 2-81).

WARNING
• Do not use the HomeLink® Universal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot
detect an object in the path of a clos-
ing garage door and then automati-
cally stop and reverse does not meet
current federal safety standards. Us-
ing a garage door opener without
these features increases the risk of
serious injury or death.
•
During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage door,
gate, etc., that you are programming.
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.
PROGRAMMING HOMELINK®
The following steps show generic instruc-
tions on how to program a Homelink® but-
ton. If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web
site at: www.homelink.com/nissan or call
1-800-355-3515.
NOTE:
It is also recommended that a new bat-
tery be placed in the hand-held trans-
mitter of the device being programmed
to Homelink® for quicker programming
and accurate transmission of the radio-
frequency.
