Front Passenger Airbag:
Visually inspect the front passenger airbag assembly (airbag
and inflater).
wUse the diagnosis check to check if there are
abnormalities.
wCheck that there are no cuts, cracks or noticeable color
changes in the front passenger airbag door.
wRemove the front passenger airbag assembly from the
vehicle and check the wiring and front passenger airbag
door for damage and corrosion due to rusting, etc.
If necessary, replace the front passenger airbag assembly.
CAUTION:
wFor removal and replacement of the steering wheel pad
or front passenger airbag assembly, see RS section and
be sure to perform the operation in the correct order.
wBefore disposing of the steering wheel pad or front pas-
senger airbag assembly must first be deployed by using
SST (See RS section).
18. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leakage.
19. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
wJack up the front of the vehicle and support it with
stands.
wMake sure the front wheels are in a straight±ahead
position, and depress the brake pedal.
wJack up the lower suspension arm until there is about
half a load on the front coil spring.
wMove the front wheel up and down and check that the
ball joint has no excessive play.
Maximum lower ball joint vertical play:
0.3 mm (0.012 in.)
If the play is greater than maximum, replace the ball joint.
(b) Visually check the dust covers for damage.
20. I NSPECT TRANSMISSION OIL (FLUID) AND
DIFFERNTIAL OIL
Visually check the transmission and differential for oil (fluid)
leakage.
If leakage is found, check for the cause and repair.
