SUPPLEMENTAL RESTRAINT SYSTEM
SRS AIRBAG
PRECAUTION
NOTICE:
The LAND CRUISER is equipped with an SRS , which comprises a driver airbag and a front pas-
S
senger airbag. Failure to carry out service operations in the correct 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 the SRS may fail to operate when re-
quired. Before performing servicing (including removal or installation of parts, inspection or
replacement), be sure to read the following items carefully, then follow the correct procedure
described in the repair manual.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
S
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.
Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front
S
passenger airbag assembly, and airbag sensor assembly should be inspected (See pages
RS−9, RS−23 and RS−34)
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
S
Never disassemble and repair the steering wheel pad, front passenger airbag assembly, or air-
S
bag sensor assembly in order to reuse it.
If the steering wheel pad, front passenger airbag assembly or airbag sensor assembly have
S
been dropped, or if there are cracks, dents or other defects in the case, bracket or connector,
replace them with new ones.
Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system's
S
electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instruc-
S
tions on the notices.
After work on the SRS is completed, check the SRS warning light (See page DI−240).
S
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
S
IN section.
CAUTION:
Work must be started after 90 seconds from the time the ignition switch is turned to the "LOCK"
S
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
of disconnecting the negative (−) terminal cable of the battery, the SRS may be deployed.)
When the negative (−) terminal cable is disconnected from the battery, the memory of the clock
S
and audio system will be canceled. So before starting work, make a record of the contents mem-
orized in the audio memory system. When work is finished, reset the audio systems as they
were before and adjust the clock. To avoid erasing the memory of each memory system, never
use a back−up power supply from outside the vehicle.
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
S
repairs.
Do not expose the steering wheel pad, front passenger airbag assembly, or airbag sensor as-
S
sembly directly to hot air or flames.
