2004 LAND CRUISER (RM1071U)
INSTALLATION
NOTICE:
Never use SRS parts from another vehicle. When re-
placing parts, replace them with new ones.
Never reuse the seat position sensor assembly in-
volved in a collision when the airbag has deployed.
Never repair a sensor in order to reuse it.
1. INSTALL SEAT POSITION SENSOR ASSEMBLY
(a) Connect the connector.
(b) Install the seat position sensor assembly with a new bolt.
Part No.:
Bolt: 90119-06871
Torque: 8.0 N´m (82 kgf´cm, 71 in.´lbf)
NOTICE:
Connection of the connector is done after the sensor
assembly has been installed.
Make sure that the sensor assembly is installed with
the specified torque.
If the sensor assembly has been dropped, or there are
cracks, dents or other defects in the case, bracket or
connector, replace the sensor assembly with a new
one.
When installing the sensor assembly, take care that
the SRS wiring does not interfere with other parts and
is not pinched between other parts.
After installation, shake the sensor assembly to
check that there is no looseness.
2. INSTALL FRONT SEAT ASSEMBLY (DRIVER SIDE)
(See page BO-1 17)
3. INSPECT SRS WARNING LIGHT (See page DI-692)

6. SEAT BELT PRETENSIONER
The seat belt pretensioner system is a component of the front
seat outer belt. The seat belt pretensioner cannot be disas-
sembled.
7. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It
goes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly self-diagno-
sis. In normal operating conditions when the ignition switch is
turned to the ON position, the light comes on for about 3 se-
conds and then goes off.
8. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
front console box. The airbag sensor assembly consists of an
airbag sensor, safing sensor, diagnosis circuit, ignition control,
drive circuit, etc. It receives signals from the airbag sensor, front
airbag sensor, side and curtain shield airbag sensor assembly,
curtain shield airbag sensor assembly and judges whether the
SRS must be activated or not. The airbag sensor assembly can-
not be disassembled.
9. FRONT AIRBAG SENSOR
The front airbag sensor is mounted on each of the radiator side
supports. The front airbag sensor consists of a frontal decelera-
tion sensor, diagnosis circuit, etc. These send signals to the air-
bag sensor assembly. The front airbag sensor cannot be disas-
sembled.
10. SIDE AND CURTAIN SHIELD AIRBAG SENSOR AS-
SEMBLY
The side and curtain shield airbag sensor assembly is mounted
in the LH and RH center pillars. The side and curtain shield air-
bag sensor assembly consist of a lateral deceleration sensor,
safing sensor, diagnosis circuit, etc. These send signals to the
airbag sensor assembly to judge whether the SRS side airbag
and curtain shield airbag must be activated or not. The side and
curtain shield airbag sensor assembly cannot be disas-
sembled.

SRS AIRBAG
PRECAUTION
CAUTION:
The LAND CRUISER is equipped with SRS, which comprises a driver airbag, front passenger
airbag, side airbag and curtain shield airbag. Failure to carry out service operations in the cor-
rect sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading
to a serious accident. Further, if a mistake is made in servicing the SRS, it is possible that the
SRS may fail to operate when required. Before performing servicing (including removal or
installation of parts, inspection or replacement), be sure to read the following items carefully,
then follow the correct procedures described in the repair manual.
Work must be started 90 seconds after the ignition switch is turned to the ºLOCKº position and
the negative (-) terminal cable is disconnected from the battery.
(The SRS is equipped with a back-up power source so that if work is started within 90 seconds
from disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)
Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,
curtain shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain
shield airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor
assembly directly to hot air or flames.
NOTICE:
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.
Even in the case of a minor collision where the SRS does not deploy, the steering wheel pad,
front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, airbag
sensor assembly, front airbag sensor, side and curtain shield airbag sensor assembly, curtain
shield airbag sensor assembly and seat position sensor assembly should be inspected (See
page RS-18, RS-32, RS-47, RS-60, RS-71, RS-76, RS-81, RS-87 and RS-92).
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side
airbag assembly, curtain shield airbag assembly, airbag sensor assembly, front airbag sensor,
side and curtain shield airbag sensor assembly, curtain shield airbag sensor assembly or seat
position sensor assembly in order to reuse it.
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain
shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain shield
airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor assem-
bly has been dropped, or if there are cracks, dents or other defects in the case, bracket or con-
nector, replace it with new one.
Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the system's
electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notice.
After work on the SRS is completed, perform the SRS warning light check (See page DI-692).
