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.

SFI INJECTOR
1996 LAND CRUISER (RM451U)
INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPE
(a) Install a new grommet to the injector.
(b) Apply a light coat of gasoline to a new O −ring and install
it to the injector.
(c) While turning the injector left and right, install it to the de-
livery pipe. Install the 6 injectors.
(d) Position the injector connector upward.
(e) Place 6 new insulators and the 3 spacers in position on the intake manifold.
(f) Place the 6 injectors together with the delivery pipe in position on the intake manifold.
(g) Temporarily install the 3 bolts holding the delivery pipe to
the intake manifold.
(h) Check that the injectors rotate smoothly.
HINT:
If injectors do not rotate smoothly, the probable cause is incor-
rect installation of O−rings. Replace the O −rings.
(i) Position the injector connector upward.
(j) Tighten the 3 bolts holding the delivery pipe to the intake manifold.

STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREEPLAY
(a) With the vehicle stopped and tires pointed straight ahead,
rock the steering wheel gently back and forth with light fin-
ger pressure.
(b) Freeplay should not exceed the maximum. Maximum freeplay: 40 mm (1.58 in.)
If the freeplay exceeds the maximum, adjust it in the following
procedure.
2. ADJUST STEERING GEAR
(a) Point the front wheels straight ahead.
(b) Loosen the adjusting screw lock nut.
(c) Turn the cross shaft adjusting screw clockwise to de- crease steering wheel freeplay and counterclockwise to
increase it.
HINT:
Turn the adjusting screw in small increments and check the
freeplay between each adjustment.
(d) Turn the steering wheel half way around in both direc- tions.
(e) Check that the freeplay is correct and steering is smooth and without rough spots.
(f) Torque the adjusting screw lock nut (See page SR−41).
3. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR−11).
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.

TRANSFER MOTOR SHIFT CONTROL SYSTEM
TR−37
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT SHIFT LEVER POSITION
(a) Start the engine, and turn the center diff lock switch to
OFF.
(b) Check that the center diff indicator light comes on when the transfer shift lever shifted to the ”L” position. Check
that the light goes off when the lever is shifted to the ”N”
or ”H” position.
2. INSPECT CENTER DIFF LOCK CONTROL RELAY
(a) Check that there is continuity between the terminals, as shown in the chart.
HINT:
There is a diode between the terminals 6 and 7. If the circuit
shown no continuity, change the positive (+) and negative ( −)
probes and recheck the circuit.
(b) Apply battery positive voltage between the terminals and check that there is continuity between the terminals, as
shown in the chart.
If continuity is not as specified, replace the relay.
