5. ECU (ELECTRONIC CONTROL UNIT)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.
Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery.
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 each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all
equipped with memory function, it is not possible to make a record of the memory contents. So when the
operation is finished, it will be necessary to explain this fact to the customer, and request the customer to
adjust the features and reset the memory.
Do not expose the ECUs to ambient temperatures above 80°C (176°F).
NOTICE: If it is possible the ambient temperature may reach 80° (176°F) or more, remove the ECUs
from the vehicle before starting work.
Be careful not to drop the ECUs and not to apply physical shocks to them.

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.

STEERING WHEEL PAD (with Airbag)
When removing the steering wheel pad or handling a new steering wheel pad, it should be placed
with the pad top surface facing up.
In this case, the twin-lock type connector lock lever should be in the locked state and care should be
taken to place it so the connector will not be damaged. In addition do not store a steering wheel pad
on top of another one. Storing the pad with its metallic surface up may lead to a serious accident if
the airbag inflates for some reason.
Never measure the resistance of the airbag squib. (This may cause the airbag to deploy, which is
very dangerous.)
Grease should not be applied to the steering wheel pad and-the pad should not be cleaned with de-
tergents of any kind.
Store the steering wheel pad where the ambient temperature remains below 93°C (200°F), without
high humidity and away from electrical noise.
When using electric welding, first disconnect the airbag connector (yellow color and 2 pins) under the
steering column near the combination switch connector before starting work.
When disposing of a vehicle or the steering wheel pad alone, the airbag should be deployed using
an SST before disposal.
Carry out the operation in a safe place away from electrical noise.
FRONT PASSENGER AIRBAG ASSEMBLY
Always store a removed or new front passenger airbag assembly with the airbag deployment direc-
tion facing up. Storing the airbag assembly with the airbag deployment direction facing down could
cause a serious accident if the airbag inflates.
Never measure the resistance of the airbag squib.
(This may cause the airbag deploy, which is very dangerous.)
Grease should not be applied to the front passenger airbag assembly and the airbag door should not
be cleaned with detergents of any kind.
Store the airbag assembly where the ambient temperature remains below 93°C (200°F), without
high humidity and away from electrical noise.
When using electric welding, first disconnect the airbag connector (yellow color and 2 pins) installed
on the glove compartment finish plate at the left side of the glove compartment before starting work.
When disposing of a vehicle or the airbag assembly alone, the airbag should be deployed using an
SST before disposal.
Perform the operation in a safe place away from electrical noise.
SEAT BELT PRETENSIONER
Before doing any operation which will apply a strong shock to the vehicle, or before removing the
seat belt pretensioner, be sure to apply the sensor shock.
Never disassemble the seat belt pretensioner.
Do not subject the seat belt pretensioner to shocks or bring magnets close to it.
Do not expose the seat belt pretensioner to high temperature or fire.
Do not drop the seat belt pretensioner. Never use a seat belt pretensioner which has been dropped.
Never install the seat belt pretensioner in another vehicle.
Store removed seat belt pretensioners on a flat, stable surface.
After frontal collision, always check whether the seat belt pretensioners have been activated.
When disposing of a vehicle or the pretensioner by itself, always activate the pretensioner before
disposal.
The seat belt pretensioner is hot when activated, so let it cool down fully before you dispose of it.
Never apply water to the seat belt pretensioner.
