2005 TOYOTA TACOMA sensor

iv2005 TACOMA from Mar. ’05 Prod. (OM35862U)
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS air-
bags makes the SRS airbags themselves potential sources
of serious injury if an occupant is too close to an airbag,
or if an object or some part of his or her body has been
placed between the occupant and the airbag at the time of
deployment. This is just one example of how the instruc-
tions in Section 1−3 of this Owner ’s Manual will help en-
sure proper use of the occupant restraint systems, and
increase the safety they can provide to you and your fami-
ly in the event of an accident.
Toyota recommends you to read the provisions in Section
1 −3 carefully and refer to them as needed during your time
of ownership of this vehicle.Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device may record
some or all of the following information:
 Engine speed
 Whether the brake pedal was applied or not
 Vehicle speed
 To what extent the accelerator pedal was depressed
 Position of the transmission selector lever
 Whether the driver and front passenger wore the
seat belts or not
 Driver ’s seat position
 Front passenger ’s occupant classification

The driver and front passenger seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the sensor detects a severe frontal
impact, the front seat belts are quickly
drawn back by the retractors so that the
belts snugly restrain the occupants.
Vehicles with bench seat—The seat belt
pretensioners are activated even with no
passenger in the front seat.Vehicles with separate seats—The front
passenger ’s seat belt pretensioner will not
activate if no passenger is detected in the
front passenger seat by the front passen-
ger occupant classification system. How-
ever, the front passenger ’s seat belt pre-
tensioner may activate if luggage is put
on the seat, or the seat belt is buckled
up regardless of the presence of an occu-
pant in the seat. (As for the front passen-
ger occupant classification system, see
“Front passenger occupant classification
system” on page 80 in this Section.)
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.
LS13103a
The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.
1. Front airbag sensors
2. SRS warning light
3. Separate seats only—Front passenger occupant classification indicator light
4. Separate seats only—Front passenger occupant classification system (ECU
and sensors)
5. Separate seats only—Front passenger ’s seat belt buckle switch
6. Seat belt pretensioner assemblies
7. Airbag sensor assembly
—Seat belt pretensioners

532005 TACOMA from Mar. ’05 Prod. (OM35862U)
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.
CAUTION
Do not modify, remove, strike or open
the seat belt pretensioner assemblies,
airbag sensor or surrounding area or
wiring. Failure to follow these instruc-
tions may prevent the seat belt pre-
tensioners from activating correctly,
cause sudden operation of the system
or disable the system, which could
result in death or serious injury. Con-
sult your Toyota dealer about any re-
pair and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
seat belt pretensioners in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the front seat
belt pretensioner assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure or con-
sole

The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
Vehicles with separate seats—Your vehicle
is equipped with “ADVANCED AIRBAGS”
designed based on US motor vehicle safe-
ty standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for
the driver and front passenger. The driver
airbag system consists of the driver seat’s
position sensor etc. The front passenger ’s
airbag system consists of the front pas-
senger occupant classification sensor etc.Vehicles with bench seat—The SRS air-
bags are designed to protect the driver
and right front passenger, and they are
not designed to protect an occupant in the
front center seating position.
In response to a severe frontal impact,
the SRS front airbags work together with
the seat belts to help reduce injury by
inflating. The SRS front airbags help re-
duce injuries mainly to the driver’s or front
passenger ’s head or chest caused by hit-
ting the vehicle interior.
Vehicles with bench seat—The SRS front
passenger airbag is activated even with
no passenger in the front seat.
Vehicles with separate seats—The SRS
front passenger airbag will not activate if
there is no passenger sitting in the front
passenger seat. However, the front pas-
senger airbag may deploy if luggage is
put in the seat. (As for the front passen-
ger occupant classification system, see
“Front passenger occupant classification
system” on page 80 in this Section.)
Always wear your seat belt properly.
CAUTION
The SRS front airbag system is de-
signed only as a supplement to the
primary protection of the driver and
front passenger seat belt systems.
The driver and front passenger can
be killed or seriously injured by the
inflating airbags if they do not wear
the available seat belts properly.
During sudden braking just before
a collision, an unrestrained driver
or front passenger can move for-
ward into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To ensure maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts properly. Wear-
ing a seat belt properly during an
accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For in-
structions and precautions concern-
ing the seat belt system, see “Seat
belts” on page 43 in this Section.
SRS driver airbag and front
passenger airbag (regular and
access cab models)

The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.1. Front airbag sensors
2. Front passenger occupant classification indicator light or passenger airbag on −
off indicator light
3. Passenger airbag manual on −off switch
4. Airbag module for front passenger (airbag and inflator)
5. Separate seats only—Front passenger occupant classification system (ECU
and sensors)
6. Separate seats only—Front passenger ’s seat belt buckle switch 7. Driver ’s seat belt buckle switch
8. Driver ’s seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver (airbag and inflator)
11. SRS warning light The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The airbag sensors constantly monitor the
forward deceleration of the vehicle. If an
impact results in a forward deceleration
beyond the designed threshold level, the
system triggers the airbag inflators. At this
time a chemical reaction in the inflators
very quickly fills the airbags with non −tox-
ic gas to help restrain the forward motion
of the occupants. The front airbags then
quickly deflate, so that there is no ob-
struction of the driver ’s vision should it be
necessary to continue driving. When the airbags inflate, they produce a
loud noise and release some smoke and
residue along with non
−toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately.

622005 TACOMA from Mar. ’05 Prod. (OM35862U)
Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see “Child
restraint” on page 86 in this Sec-
tion.
LS13115
Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the front airbag sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of the deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.
Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover, dashboard
near the front passenger airbag,
front passenger airbag cover, front
passenger airbag or airbag sensor
assembly. Doing so may prevent the
front airbag system from activating
correctly, cause sudden activation
of the system or disable the sys-
tem, which could result in death or
serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.
If you wish to modify your vehicle for
a person with a physical disability,
consult your Toyota dealer. It may
dangerously interfere with the SRS
front airbags operation.
