2022 NISSAN FRONTIER ECU

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 de-
vices 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 ve-
hicle's battery is discharged or is discon-
nected, HomeLink® will retain all
programming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (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. 2-77).WARNING
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. For
additional information, see “Push-
button ignition switch” (P. 5-13). 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.
• 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.
PROGRAMMING HOMELINK®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON or ACC
position (without starting the engine)
when programming HomeLink®. It is also
recommended that a new battery be
placed in the hand-held transmitter of
the device being programmed to
HomeLink® for quicker programming
and accurate transmission of the radio
frequency. 1. Position the end of your hand-held
transmitter 1–3 in (2–8 cm) away from
the HomeLink® surface, keeping the
HomeLink® indicator light
O1in view. 2. Using both hands, simultaneously press
and hold the desired HomeLink® button
and hand-held transmitter button. DO
NOT release until the HomeLink® indica-
tor light
O1flashes slowly and then rap-
idly. When the indicator light flashes rap-
idly, both buttons may be released. (The
rapid flashing indicates successful
programming.)

through unintended operation of the
vehicle and/or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
