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.

HINT:
The ECM memorizes the condition that the ECT controls the automatic transmission assy and engine assy
according to those characteristics. Therefore, when the automatic transmission assy, engine assy, or ECM
has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
Reset procedure is as follows.
(a) Turn the ignition switch off.
(b) Connect the hand-held tester to the DLC3.
(c) Turn the ignition switch to the ON position and push the hand-held tester main switch on.
(d) Select the item ºDIAGNOSIS/ENHANCED OBD IIº.
