Heated Steering Wheel
INFOID:0000000008461709
The heated steering wheel is activated by the power supply from the heated steering wheel relay.
Furthermore, the heated steering wheel incorporates a heating element and a thermostat to control heated
steering wheel temperatures.
• Heating element: Heat is generated by the passage of an electric current.
• Thermostat: ON/OFF operation of power supply at a certain temperature.
Heated Steering Wheel Switch
INFOID:0000000008461710
• Controls the heated steering wheel relay and operates the heated steering wheel system.
The heated steering wheel switch incorporates a timer and turns OFF the heated steering wheel relay when
operating time reaches a certain time.
- Timer: ON/OFF operation of the heated steering wheel relay at a certain time.
• Turns the indicator lamp ON when the system is activated.
Heated Steering Wheel Relay
INFOID:0000000008461711
Operates the heated steering system with the control signal from the heated steering wheel switch.

SYSTEM
System Description (Heated Steering Wheel)
INFOID:0000000008461712
The heated steering wheel switch controls the heated steering wheel relay. When the heated steering wheel
switch is turned on, the heated steering wheel relay is energized and the heated steering wheel system will
operate. The heated steering wheel system will turn off when the heated steering wheel temperature reaches
approximately 30
°
C (86
°
F). Heated steering wheel system operation can also be canceled by pressing the
heated steering wheel switch again. In addition, the heated steering wheel switch incorporates a timer and
turns OFF the heated steering wheel relay to exit the heated steering wheel system when the operating time
reaches a certain time.
NOTE:
If the surface temperature of the steering wheel is below 20
°
C (68
°
F), the system will heat the steering wheel
and cycle off and on to maintain a temperature above 20
°
C (68
°
F). The indicator lamp will remain on as long
as the system is on. Push the switch again to turn the heated steering wheel system off manually. The indica-
tor lamp will go off.

Inspect the relation of the symptoms and the condition when the symptoms occur.
>> GO TO 3.
3.
IDENTIFY THE MALFUNCTIONING SYSTEM WITH “SYMPTOM DIAGNOSIS”
Use “Symptom diagnosis” from the symptom inspection result in step 2 and then identify where to start per-
forming the diagnosis based on possible causes and symptoms.
>> GO TO 4.
4.
IDENTIFY THE MALFUNCTIONING PARTS WITH “COMPONENT DIAGNOSIS”
Perform the diagnosis with “Component diagnosis” of the applicable system.
>> GO TO 5.
5.
REPAIR OR REPLACE THE MALFUNCTIONING PARTS
Repair or replace the specified malfunctioning parts.
>> GO TO 6.
6.
FINAL CHECK
Check that malfunctions are not reproduced when obtaining the malfunction information from the customer,
referring to the symptom inspection result in step 2.
Are the malfunctions corrected?

INFOID:0000000008461715
NEUTRAL POSITION STEERING WHEEL
1.
Check that steering gear assembly, steering column assembly and steering wheel are installed in the cor-
rect position.
2.
Check wheel alignment within specification. Refer to
.
3.
Set the vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
• 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.
CAUTION:
If the adjustment is performed by using the inner socket, check wheel alignment after the adjust-
ment. Refer to
.
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
3.
Start the engine.
4.
Bring power steering fluid up to adequate operating temperature.
5.
Check steering wheel turning force when steering wheel has
been turned 540
°
from neutral position.
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
RACK SLIDING FORCE
1.
Disconnect lower joint and steering knuckle from steering gear assembly. Refer to
.
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.
Perform toe-in inspection. Refer to
.
CAUTION:
Perform front wheel turning angle inspection, after toe-in 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.
• With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.
• Check the following items when turning angle is out of the
standard.
- Check the neutral position of the rack stroke (L).
- Disassemble steering gear assembly to check the cause that
rack stroke is outside of the standard.
• Steering angles are not adjustable. Check steering gear
assembly, steering column assembly and front suspension
components for wear or damage if any of the turning angles are different from the specified value.
Replace any of them, if any non-standard condition exists.
