Items and procedures for general maintenance are as follows.
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner’s manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performe\

Periodic maintenance service must be performed according to whichever interval in\
the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
2. LIGHTS
(a) Check that the headlights, stop lights, taillights, turn signal lights, \
and other lights are all working.
(b) Check the headlights aim.
3. WARNING LIGHTS AND BUZZERS

5. WINDSHIELD
Check for scratches, pits or abrasions.
6. WINDSHIELD WIPER AND WASHER
(a) Check operation of the wipers and washer.
(b) Check that the wipers do not streak.
7. WINDSHIELD DEFROSTER
Check that air comes out from the defroster outlet when operating the heater \
or air conditioner at defroster
mode.
8. REAR VIEW MIRROR
Check that it is mounted securely.
9. SUN VISORS
Check that they move freely and mounted securely.
10. STEELING WHEEL
Check that it has the specified freeplay. Be alert for changes in steering condition, such as hard steering,
excessive freeplay or strange noises.
11. SEATS
(a) Check that all front seat controls such as seat adjusters, seatback recl\
iner, etc. operate smoothly.
(b) Check that all latches lock securely in any position.
(c) Check that the head restraints move up and down smoothly and that the lo\
cks hold securely in any latch position.
(d) For folding −down rear seat backs, check that the latches look securely.

HINT:
w/ differential lock:
Before installation, check differential lock operation connecting the connector of the actuator to the
connector of the vehicle side.

1996 LAND CRUISER (RM451U)
DIFFERENTIAL LOCKING SYSTEM
ON−VEHICLE INSPECTION
1. INSPECT DIFFERENTIAL LOCK SYSTEM
(a) Inspect the indicator lights.
Check that the indicator lights (front side and rear side)
light up for approx. 1 second when the ignition switch is
turned ON.
(b) Inspect the differential lock operation. (1) Jack up the vehicle then start the engine.
(2) Put the transfer shift lever on the L position.
(3) When the Diff. lock control switch is set to the RR
position, the indicator light (rear side) is turned on.
Differential lock is applied to the rear wheel at this
time.
HINT:
If the gears of the differential lock system are not meshed, the
indicator light remains blinking, so rotate the tires to mesh the
gear.
(4) When the Diff. lock control switch is at the OFF posi-
tion, the indicator light goes off.
Differential lock is released for the rear wheel at this
time.
(5) When the Diff. lock control switch is set to the FR/ RR position, the indicator lights (front side and rear
side) are turned on.
Differential lock is applied to both the front wheels
and rear wheels at this time.

(6) Check the voltage between the terminals of the Diff.
lock ECU when switching the Diff. lock control
switch with the speedometer, registering approx. 8
km/h (5 mph) or more.
(7) Check that the indicator lights blink when center Diff. lock release mode is set.
Diff. lock is released for both the front wheels and
rear wheels at this time.
(8) Return the Diff. lock control switch to OFF.
(9) Stop the engine and lower the vehicle.
2. INSPECT DIFF. LOCK SYSTEM CIRCUIT
(a) Inspect the system circuit with connector disconnected. Disconnect the connector from the Diff. lock ECU and in-
spect the connector on the wire harness side, as shown
in the chart.
