DRAINING
1. Stop engine.
2. Remove drain plug (1) and drain gear oil.
3. Set a gasket on drain plug (1) and install it to final drive assem-
bly and tighten to the specified torque. Refer to RFD-18, "
COM-
PONENTS" .
CAUTION:
Do not reuse gasket.
FILLING
1. Remove filler plug (1). Fill with new gear oil until oil level reaches
the specified level near filler plug mounting hole.
2. After refilling oil, check oil level. Set a gasket to filler plug (1),
then install it to final drive assembly. Refer to RFD-18, "
COMPO-
NENTS" .
CAUTION:
Do not reuse gasket.
Checking Differential Gear OilNDS000F4
OIL LEAKAGE AND OIL LEVEL

Make sure that oil is not leaking from final drive assembly or around it.

Remove filler plug (1) and check oil level from filler plug mount-
ing hole as shown in the figure.
CAUTION:
Do not start engine while checking oil level.

Set a gasket on filler plug (1) and install it on final drive assem-
bly. Refer to RFD-18, "

CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

Remove the cell plug using a suitable tool.

Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Use the chart below to correct your hydrometer reading accord-
ing to electrolyte temperature.

For Fast and Accurate Trouble DiagnosisNGS000E1
Check the following items with the vehicle stopped

Is air pressure and size of tires proper?

Is the specified part used for the steering wheel?

Is control unit a genuine part?

Are there any fluid leakage from steering gear assembly, power steering oil pump, and hydraulic pipes,
etc? Refer to PS-8, "
Checking Fluid Leakage" .

Is the fluid level proper? Refer to PS-8, "Checking Fluid Level" .

Is the wheel alignment adjusted properly? Refer to FSU-6, "Wheel Alignment Inspection" (2WD), FSU-24,
"Wheel Alignment Inspection" (AWD).

Are there any damage or modification to suspension or body resulting in increased weight or altered
ground clearance?

Check each link installation condition of suspension and axle.

Check each connector connection condition.
Check the following items while driving the vehicle

Check conditions when the malfunction occurred (5W 1H).

Is the engine condition normal?
Basic InspectionNGS000E2
POWER SUPPLY CIRCUIT TERMINAL LOOSENESS AND BATTERY
Check battery terminals for looseness on both positive and negative ones and ground connection. Also make
sure that battery voltage does not drop.
Inspection: Power Steering Control Unit Power Supply Circuit and GroundNGS000E3
1. CHECK POWER STEERING CONTROL UNIT CONNECTOR
Turn ignition switch OFF, disconnect power steering control unit harness connector, and check terminal for
deformation, disconnection, looseness, etc.
OK or NG
OK >> GO TO 2.
NG >> Connector terminal connection is loose, damaged, open, or shorted. Repair or replace the termi-
nal.
2. CHECK POWER STEERING CONTROL UNIT GROUND CIRCUIT
Disconnect power steering control unit harness connector M8, and
then check continuity between power steering control unit harness
connector M8 and ground.
OK or NG
OK >> GO TO 3.
NG >> Ground circuit open or shorted. Repair or replace any
inoperative parts. Terminal 2 – Ground : Continuity exist.

Check battery terminals for looseness on both positive and negative ones and ground connection. Also make
sure that battery voltage does not drop.
BASIC INSPECTION 2: RAS WARNING LAMP INSPECTION
1. Make sure RAS warning lamp turns on when ignition switch is turned ON.

If it does not turn on, refer to STC-33, "Trouble Diagnosis Chart" .
2. Make sure that RAS warning lamp turns off when the engine is started after ignition switch is turned ON. If
it does not turn off, perform self-diagnosis. Refer to STC-28, "
SELF-DIAG RESULT MODE" .
3. Always erase DTC memory after completing self-diagnosis. Refer to STC-29, "
