SYMPTOM DIAGNOSIS
SECURITY CONTROL SYSTEM
Symptom TableINFOID:0000000003815090
The engine start function, door lock function, power distribution system and NATS-IVIS/NVIS in the Intelligent
Key system are closely related to each other regarding control. Narrow down the functional area in question
by performing following table to identify which function is malfunctioning. The vehicle security function can
operate only when the door lock and power distribution system are operating normally. Therefore, it is easy to
identify any factor unique to the vehicle security system by performing following table.
Use the chart below to help you find the cause of the symptom. The numbers indicate the order of the inspec-
tion.
NOTE:
Before starting vehicle security system operation check, the following conditions must be met.
 Open front windows

POWER STEERING FLUID
InspectionINFOID:0000000003826225
FLUID LEVEL
1. Check fluid level with engine stopped.
2. Ensure that fluid level is between MIN and MAX.
3. Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
 The fluid level should not exceed the MAX line. Excessive fluid causes fluid leakage from the
cap.
 Never reuse drained power steering fluid.
FLUID LEAKAGE
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run the engine until the fluid temperature reaches 50 to 80°C
(122 to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully check for fluid leakage.
CAUTION:
Never hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that power steer-
ing oil pump assembly may be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to ST-32, "
Inspection".
6. Check steering gear boots for accumulation of fluid leaked from steering gear.
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, the following symptoms can be observed.
 Bubbles are created in reservoir tank.
 Clicking noise can be heard from oil pump.
 Excessive buzzing in the oil pump.
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of the
system.
1. Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
Fill reservoir tank with a sufficient amount of fluid so that fluid level is not below the MIN line while
turning steering wheel.
2. Start the engine and hold steering wheel at each lock position for 3 second at idle to check for fluid leak-
age.HOT (A) : Fluid temperature 50 – 80°C (122 – 176°F)
COLD (B) : Fluid temperature 0 – 30°C (32 – 86°F)
Recommended fluid : Refer to MA-11, "
Fluids
and Lubricants".
Fluid capacity : Refer to ST-37, "
General
Specifications".

3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Never hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)
4. Check fluid for bubbles and white contamination.
5. Stop the engine if bubbles and white contamination do not drain out. Perform step 2 and 3 above after
waiting until bubbles and white contamination drain out.
6. Stop the engine, and then check fluid level.

STEERING WHEEL AXIAL END PLAY
1. Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
2. Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
3. Check the following items when steering wheel axial end play is out of the standard.
 Check the steering column assembly mounting condition. Refer to ST-13, "
Exploded View".
 Check steering gear assembly mounting condition for looseness. Refer to ST-18, "
Exploded View".
STEERING WHEEL PLAY
1. Turn steering wheel so that front wheels come to the straight-ahead position.
2. Start the engine and lightly turn steering wheel to the left and right until front wheels start to move.
3. Measure steering wheel movement on the outer circumference.
4. Check the following items when steering wheel play is out of the standard.
 Check backlash for each joint of steering column assembly.
 Check installation condition of steering gear assembly.
NEUTRAL POSITION STEERING WHEEL
1. Check that steering gear assembly, steering column assembly and steering wheel are installed in the cor-
rect position.
2. Perform neutral position inspection after wheel alignment. Refer to FSU-7, "
Wheel Alignment Inspection".
3. Set the vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
4. Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
STEERING WHEEL TURNING FORCE
1. Park the vehicle on a level and dry surface, set parking brake.
2. Tires need to be inflated normal pressure. Refer to WT-5, "
Tire Air Pressure".
3. Start the engine.
4. Bring power steering fluid up to adequate operating temperature.Standard

5. Check steering wheel turning force when steering wheel has
been turned 540° from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
6. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump. Regarding relief hydraulic pressure of oil
pump, refer to ST-32, "
Inspection".
RACK SLIDING FORCE
1. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to ST-16, "Exploded
View".
2. Start and run the engine at idle to make sure steering fluid has reached normal operating temperature.
3. While pulling outer socket slowly in ±11.5 mm (±0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
4. If rack sliding force is not within specification, overhaul steering
gear assembly.
FRONT WHEEL TURNING ANGLE
1. Check front wheel turning angle after toe-in inspection. Refer to FSU-7, "Wheel Alignment Inspection".
2. Place front wheels on turning radius gauges and rear wheels on
stands, so that vehicle can be level.
3. Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
4. With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.Standard
