1996 RAV4 (RM447U)
INSPECTION
1. INSPECT CENTER DIFFERENTIAL LOCK SYSTEM
(a) Inspect the differential lock operation.
(1) Use a lift or jack stand to lift up the vehicle so that
all 4 tires can rotate.
(2) Apply the parking brake and start the engine.
(3) Set the center differential lock switch to ON.
(4) Depress the clutch pedal and shift into the 2nd gear.
(5) With the engine idling, gradually engage the clutch
and check that the engine stops.
(6) With the parking brake and engine ON, turn the cen-
ter differential lock switch OFF.
(7) Depress the clutch pedal and shift into the 2nd gear.
(8) With the engine idling, gradually engage the clutch
and check that the front wheels rotate.
HINT:
This inspection must be done when the engine is idling.
(b) Inspect the center differential lock indicator operation.
(1) Turn the ignition switch ON.
(2) Check that when the differential lock switch is
turned ON and OFF, the differential lock indicator
lamp lights up and goes off, respectively.
(c) Inspect the center differential lock warning buzzer opera-
tion.
(1) Start the engine and check that the differential lock
warning buzzer does not sound when the center dif-
ferential lock switch is turned ON.
(2) Interchange the solenoid hose No.1 and solenoid
hose No.2 between the differential lock control sole-
noid No.1 and No.2 and the differential lock actua-
tor. And check that the differential lock warning
buzzer sounds when the differential lock switch is
turned OFF.
(3) Return the solenoid hose No.1 and solenoid hose
No.2 to their original location, and check that the dif-
ferential lock warning buzzer stops.
HINT:
Do the inspection with the vehicle stopped.
After finishing the inspection, inspect the differential lock
control solenoid hoses.

(d) Install the SST.
CAUTION:
Place the disc wheel on level ground.
(1) Connect the SST connector to the steering wheel
pad connector.
SST 09082−00700, 09082−00760
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock. Also, pro-
vide some slack for the SST wire harness inside the disc
wheel.
(2) Move the SST to at least 10 m (33 ft) away from the
steering wheel pad tied down on the disc wheel.
(e) Cover the steering wheel pad with cardboard box or tires.
Covering method using cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
x= 460 mm (18.11 in.)
When dimension y of the cardboard box exceeds the
diameter of the disc wheel with tire to which the steer-
ing wheel pad is tied −
x= 460 mm (18.11 in.) + width of tire
y= 650 mm (25.59 in.)
NOTICE:
If a cardboard box smaller than the specified size is used,
the cardboard box will be broken by the shock of the airbag
deployment.
Covering method using tires:
Place at least 3 tires without disc wheel on top of the
disc wheel with tire to which the steering wheel pad
is tied.
Tire size: Must exceed the following dimensions−
Width: 185 mm (7.28 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Do not use tires with disc wheels.

NOTICE:
The tires may be marked by the airbag deployment, so use
redundant tires.
(f) Deploy the airbag.
(1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(−) terminal.
(2) Confirm that no one is within 10 m (33 ft) area
around the disc wheel to which the steering wheel
pad is tied.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
(g) Dispose of the steering wheel pad (with airbag).
CAUTION:
The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.
Use gloves and safety glasses when handling a steer-
ing wheel pad with deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
deployed airbag.
(1) Remove the steering wheel pad from the disc
wheel.
(2) Place the steering wheel pad in a vinyl bag, tie the
end tightly and dispose of it in the same way as oth-
er general parts.

With the vehicle stopped and tires facing straight ahead, rock
the steering wheel gently back and forth with light finger pres-
sure.
Freeplay should not exceed the maximum.
Maximum freeplay: 30 mm (1.18 in.)
2. CHECK STEERING EFFORT
(a) Center the steering wheel.

(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.
Reference: 5.9 N·m (60 kgf·cm, 52 in.·lbf)
HINT:
Be sure to consider the tire type, pressure and contact surface
before making your diagnosis.
(e) Torque the steering wheel set nut.
