System Description
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to alternator terminal 4 (S) through:
I10A fuse (No. 31, located in the fuse and fusible link box).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage
is controlled by the IC regulator at terminal 4 (S) detecting the input voltage (ZD30DDTi engine models). The
charging circuit is protected by the 100A (A/T models) fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
Ithrough 10A fuse [No. 12, located in the fuse block (J/B)]
Ito combination meter terminal 28 for the charge warning lamp.
Ground is supplied to terminal 2 of the combination meter through terminal 1(L) (TD27Ti engine models) or
3(L) (ZD30DDTi engine model) of the alternator. With power and ground supplied, the charge warning lamp
will illuminate. When the alternator is providing sufficient voltage with the engine running, the ground is opened
and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

Checking Steering Wheel Play
1. With wheels in a straight-ahead position, check steering wheel
play.
Steering wheel play:
35 mm (1.38 in) or less
2. If it is not within specification, check steering gear assembly
when front suspension and axle, steering gear assembly and
steering column are mounted correctly.
Checking Neutral Position on Steering Wheel
CHECKING
1. Check that the steering wheel is in the neutral position when
driving straight ahead.
2. If it is not in the neutral position, remove the steering wheel and
reinstall it correctly.
3. If the neutral position is between two serrated teeth, loosen
tie-rod lock nut and move tie-rod in the opposite direction by the
same amount on both left and right sides to compensate for
error in the neutral position.
Front Wheel Turning Angle
Rotate steering wheel all the way right and left; measure turning
angle.
Turning angle of full turns:
Refer to section FA for SDS.
Checking and Adjusting Drive Belts
Refer to section MA for Drive Belt Inspection.
Checking Fluid Level
Check the fluid level in the reservoir when the engine is cold. If the
fluid level is below the MIN line, and fluid up to the MAX line.
CAUTION:
IDo not overfill.
IUse only ªDEXRON
TMº type automatic transmission fluid.

Checking Fluid Leakage
Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing or deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 60 to 80ÉC
(140 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds and
carefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
4. If fluid leakage at connectors is noticed, loosen flare nut and
then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
Bleeding Hydraulic System
1. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Meanwhile quickly turn
steering wheel fully to right and left and lightly touch steering
stoppers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2 above.
IIncomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a. Generation of air bubbles in reservoir tank
b. Generation of clicking noise in oil pump
c. Excessive buzzing in oil pump
While the vehicle is stationary or while moving the steering wheel
slowly, fluid noise may occur in the valve or oil pump. This noise is
inherent in this steering system, and it will not affect performance
or durability of the system.

Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture.
Temperature:
60É - 80ÉC (140 - 176ÉF)
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from neutral position.
Steering wheel turning force:
39 N (4 kg, 9 lb) or less
IIf steering wheel turning force is not within specification,
perform the following inspection procedure:
