2004 LAND CRUISER (EWD548U)
237 SRS
NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary
instructions and the procedure and precautions in the Repair Manual for the applicable model year.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information
when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
Work must be started after 90 seconds from when 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.)
When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is
finished, reset the audio systems as they were before and adjust the clock. This vehicle has power tilt and power
telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.
However, it is not possible to make a record of the memory contents. So when the work is finished, it will be necessary
to explain this fact tot the customer, and ask the customer to adjust the features and reset the memory. To avoid erasing
the memory in 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 repairs.
Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag
assembly, seat belt pretensioner, center airbag sensor assembly, front airbag sensor assembly or side airbag sensor
assembly directly to hot air or flames.
Even in cases 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, seat belt pretensioner, center airbag sensor assembly,
front airbag sensor assembly and side airbag sensor assembly should be inspected.
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, seat belt pretensioner, center airbag sensor assembly, front airbag sensor assembly or side
airbag sensor assembly in order to reuse it.
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, seat
belt pretensioner, center airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly has
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 kW/V minimum) for troubleshooting the system's electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.
After work on the SRS is completed, perform the SRS warning light check.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.

- INTRODUCTIONFOR ALL OF VEHICLES

2004 LAND CRUISER (RM1071U)
FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The LAND CRUISER is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag, front
passenger airbag assembly and seat belt pretensioner.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly 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 cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic 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 (See page DI-692).
(2) 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 discon-
nected 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 neg-
ative (-) terminal cable from the battery, the SRS
may deploy.)
When the negative (-) terminal cable is discon-
nected 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 each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back-up power supply from anoth-
er battery.
