SUPPLEMENTAL RESTRAINT SYSTEM AIRBAG SENSOR ASSEMBLY
1996 LAND CRUISER (RM451U)
INSTALLATION
NOTICE:
Never use SRS parts from another vehicle. When replacing parts, replace with \
new parts.
Never reuse the airbag sensor assembly involved in a collision when the airbag has deployed.
Never repair a sensor in order to reuse it.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Using a torx wrench, install the airbag sensor assembly with the 4 screw\
s. Torx wrench: T40 (Part No. 09042 −00020 or locally manufactured tool)
Torque: 21 N·m (210 kgf·cm, 15 ft·lbf)
(b) Connect the connector.
NOTICE:
Installation of the connector is done with the sensor assembly installed\
.
Make sure the sensor assembly is installed to the specified torque.
If the sensor assembly has been dropped, or there are cracks, dents or o\
ther defects in the
case, bracket or connector, replace the sensor assembly with a new one.
When installing the sensor assembly, take care that the SRS wiring does not interfere with other
parts and is not pinched between other parts.
After installation, shake the sensor assembly to check that there is no \
looseness.
2. INSTALL THE REMOVED PARTS

SFI SYSTEM
PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (−) TERMINAL CABLE FROM THE
BATTERY.
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative ( −) terminal cable is disconnected.
Therefore, if necessary, read the diagnosis before disconnect-
ing the negative ( −) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME WHEN WORKING ON FUEL SYSTEM.
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEA TH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) In event of engine misfire, these precautions should be taken.
(1) Check proper connection of battery terminals, etc.
(2) Handle high −tension cords carefully.
(3) After repair work, check that the ignition coil termi- nals and all other ignition system lines are recon-
nected securely.
(4) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Precautions when handling the oxygen sensor. (1) Do not allow the oxygen sensor to drop or hit
against an object.
(2) Do not allow the sensor to come in contact with wa- ter.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RA-
DIO
SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV hose, etc. may cause the engine to run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, etc., first disconnect the power by either turning the ignition
switch OFF or disconnecting the negative ( −) terminal
cable from the battery.

HINT:
Always check the diagnostic trouble code before disconnecting
the negative ( −) terminal cable from the battery.
(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative ( −) cables.
(c) Do not permit parts to receive a severe impact during re- moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Do not be careless during troubleshooting as there are numerous transistor circuits and even slight terminal con-
tact can further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care is required when pulling out and inserting wiring con-
nectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) When inspecting a connector with a volt/ohmmeter (1) Carefully take out the water −proofing rubber if it is
a water−proof type connector.
(2) Insert the test probe into the connector from the wir-
ing side when checking the continuity, amperage or
voltage.
(3) Do not apply unnecessary force to the terminal.
(4) After checking, install the water−proofing rubber on
the connector securely.
(j) Use SST for inspection or test of the injector or its wiring connector.

IDLE AIR CONTROL (IAC) VALVE
ON−VEHICLE INSPECTION
1. INSPECT IAC VALVE FOR OPERATING SOUND
Check that there is a clicking sound immediately after stopping
the engine.
If the operation is not as specified, check the IAC valve, wiring
and ECM.
2. INSPECT IAC VALVE RESISTANCE
(a) Disconnect the IAC valve connector.
(b) Using an ohmmeter, measure the resistance between the
terminals (B1 −S1 and S3, B2−S2 and S4).
Resistance:
At Cold: −10 − 50°C (−50 − 122°F): 15 − 25 Ω
At Hot: 50 −100°C (122 − 212° F): 20 − 30 Ω
If resistance is not as specified, replace the IAC valve.
(c) Reconnect the IAC valve connector.
