MAINTENANCE AND REPAIR ON-VEHICLE SERVICE INSPECTION Steering Wheel Freeplay Inspection Procedure
1. Start the engine and set the wheels in straight ahead position.
2. Slightly move the steering wheel to the left and right andmeasure steering wheel free play when the front wheel is
start to move. Notice
If exceeds specification, the steering column shaft
connections and steering linkage .clearance. Replace orrepair if necessary.
Steering Angle Inspection Procedure
1. Place the front wheel on a measuring tool.
2. Rotate steering wheel all the way right and left and measure steering angle Notice If out of standard, check or adjust toe-in.
Standard 33°37'
31°50'Inner
Outer
Steering Effort Inspection Procedure
1 Place a vehicle on the paved flat ground with front wheels in a straight ahead position.
2 Start the engine and run it at 1,000rpm.
3 Using a scale, measure the steering effort in both directions.
NoticeThe difference in steering effort of left and right should be within 0.6 kg.
Standard Max. 3.0kg
StandardMax. 30mm

6A-6 POWER STEERING SYSTEM
OIL PUMP PRESSURE CHECK Oil Pump Pressure Check
1. Disconnect the pressure hose from the oil pump connect apressure gauge between the oil pump and pressure hose
2. Bleed the system . Start the engine and turn the steering wheel form lock several times until oil temperature is up to
50°C
3. Run the engine at 1,000 rpm.
4. Close the pressure gauge valve and check oil pressure.
NoticeDo not keep the valve closed for more than 10 seconds.
5. Remove the pressure gauge and connect the pressure hose.
6. Do bleeding procedure. BLEEDING OF POWER STEERING SYSTEM Bleeding of Power Steering System
1. Disconnect the fuel line. Using a starter motor, crank the engine and turn the steering wheel from lock to lock 5 or 6 times. Notice Do bleeding with engine cranking. If bleed with idling, there can be a air contact with oil.
2. Connect the fuel feed line and start the engine at idle speed.
3. Turn the steering wheel from lock to lock until there is no more air in oil reservoir.
4. Connect the oil level is within specification.
5. By turning the steering wheel left to right, check the oil level change. Notice
If oil is not changes more than 5mm, do bleeding again.
If oil level rises suddenly when stopped engine, again.

Water Sensor
Water sensor is a thermistor that detects engine coolant temperature to operate the blower speed to LO when water temperature is less than 50.
1. Check that there are water sensor fault code (15,16) by
using self-diagnosis function.
3. Check that measured resistance value among water sensor terminals is as shown in the right side graph. Notice Measure resistance value by soaking the sensor in the ice water and check changes in resistance values after soaking
it in the very hot water.
4. If resistance value is out of specification, replace the water sensor.
5. Install the sensor and turn the ignition switch to ON position and check that voltage between No. 7a terminal of the water
sensor and body (-) is 5V.
6. Check current between the No. 7a and 7b connector terminals of the water sensor and the No. 3 and 5 connector terminals of the airconditioner control unit and repair the wire if defective.
2. Disconnect water sensor 2-pin connector that installed on
the heater unit of inner instrument panel and remove the
water sensor.

CAUTIONS
Failure to follow the correct service procedure can cause air bag damage or personal injury due to unexpected air
bag deployment. Before service (removal and installation of part, check for replacement), please be weal noticed offollowing items for your correct service.
1. For service, turn the ignition switch to ‘LOCK’ position and wait for 30 seconds after disconnecting the negative battery cable.
2. If the vehicle collapsed, remove the air bag ECU first to reserve the crash records.
3, Never use other vehicles’ air bag components and replace with specified new part.
4. Never disassemble or repair the air bag module, air bag unit and wiring harness to re-use.
5. Replace the air bag module and air bag unit with new if it dropped, cracked or damaged.
6. Only qualified technicians in service shop should check or repair the air bag,
7. Before service, should be well noticed of warning labels on the vehicle.
A. Sun Visor Side
[Warning] Pull down the sun visor and see SRS air bag warning lamp on the head lining. B. Head Lining
[Warning]
1 . This vehicle is equipped with air bag. Air bag is supplemental device for the seatbelt. Fasten your seatbelt.
2. This air bag should be replaced by authorized supplier within replacement intervals.
3. When the ignition key is turned to ON position, SRS warning lamp will turn on for 6 sec. and go off. In this case, the system is normal. For the following cases, see service manual. - SRS warning lamp does not turn on. - SRS warning lamp does not go off.- SRS warning lamp continues to blink.
C. Steering Wheel Body Inner
[Warning] Before removing the steering wheel, read service manual first. Set the front wheels straight forward
and align the center position marks of SRS clock spring. Improper removal or installation of the steering wheel can damage the SRS components. D. Engine Compartment
[Warning] This vehicle is equipped with air bag. Before checking the engine compartment, read servicemanual first. Faultuy check and service can cause SRS air bag deployment and system defects that can be led to severe damage. E. Battery Cable
[Warning]
Before disconnecting the battery power, read service manual first.
