HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
The TOYOTA LAND CRUISER is equipped with an SRS (Supplemental Restraint System), such as the driver
airbag and front passenger airbag and seat belt pretensioners. Failure to carry out service operations in the
correct sequence could cause the supplemental restraint system to unexpectedly deploy during servicing, pos-
sibly leading to a serious accident. Further, if a mistake is made in servicing the supplemental restraint system,
it is possible the SRS may fail to operate when required. Before servicing (including removal or installation of
parts, inspection or replacement), be sure to read the following items carefully, then follow the correct proce-
dure described in this manual.

Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the diagnostic
trouble codes become the most important source of information when troubleshooting.
When troubleshooting the supplemental restraint system, always inspect the diagnostic trouble codes
before disconnecting the battery.

Work must be started after 90 seconds from the time the ignition switch is turned to the ºLOCKº position
and the negative (-) terminal cable is disconnected from the battery.
(The supplemental restraint system is equipped with a back-up power source so that if work is started
within 90 seconds of disconnecting the negative (-) terminal cable from the battery, the SRS may
deploy.)
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by the
audio memory system.
Then when work is finished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory system, never use a back-up power supply from outside
the vehicle.

Even in cases of a minor collision where the SRS does not deploy, the passenger's airbag assembly,
the steering wheel pad and seat belt pretensioners should be inspected.
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.

Never disassemble and repair the airbag sensor assembly, steering wheel pad in order to reuse it.

If the airbag sensor assembly, steering wheel pad have been dropped, or if there are cracks, dents or
other defects in the case, bracket or connector, replace them with new ones.

Do not expose the airbag sensor assembly, steering wheel pad directly to hot air or flames.

Use a volt/ohmmeter with high impedance (10 k
/V minimum) for troubleshooting of the electrical cir-
cuit.

Information labels are attached to the periphery of the SRS components. Follow the instructions on the
notices.

After work on the supplemental restraint system is completed, check the SRS warning light.

Before repairing the body, remove the SRS parts if, during repair, shocks are likely to be applied to the
sensors due to vibrations of the body or direct tapping with tools or other parts.

Do not expose the SRS parts directly to hot air or flames.
NOTICE:
1) The maximum ambient temperature tolerance is 120
°C (248°F) for the front airbag sensor, 105°C
(221
°F) for the center airbag sensor assembly and 93°C (200°F) for the steering wheel pad, and
front passenger airbag assembly. If it is possible that the ambient temperature may reach or ex-
ceed the temperature limit, remove the sensors and the steering wheel pad from the vehicle or
protect them with a hot insulation material before staring work.
2) Prior to welding, remove adjacent SRS parts form the vehicle or protect them with fire-proof cov-
ers.

If the vehicle is damaged, visually inspect for damage to the steering wheel pad using the inspection
procedures described in section RS of the repair manual for the relevant model year.

AIRBAG SENSOR ASSEMBLY

Never reuse the airbag sensor assembly involved in a collision when the SRS has deployed.

The connectors to the airbag sensor assembly should be connected or disconnected with the sensor
mounted on the floor. If the connectors are connected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause undesired ignition of the supplemental restraint sys-
tem.

Work must be started after 90 seconds from the time the ignition switch is turned to the ºLOCKº posi-
tion and the negative (-) terminal cable is disconnected from the battery, even if only loosening the
set bolts of the airbag sensor assembly.
WIRE HARNESS AND CONNECTOR

The SRS wire harness is integrated with the cowl wire harness assembly and floor wire harness as-
sembly. The wires for the SRS wire harness are encased in a yellow corrugated tube. All the connec-
tors for the system are also a standard yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc., repair or replace it as shown on page.
2. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model year when handling brake sys-
tem parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC
system.
3. DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance
and vibration resistance of the vehicle. After installing components in the sections listed in the table
below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate
repair of the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions
given in the repair manual for the relevant model during alignment and section Dl of this manual.
4. COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels. Strictly ob-
serve the following precautions to prevent damaging these components and the body panels during
handling.

Before repairing the body panels, remove their components or apply protective covers over the com-
ponents.

Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components and the body paint.

Before removing components from the outer surface of the body, attach protective tape to the body
to ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.

Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.
