134On-vehicle inspection1. check the drive belt
Observe the drive belt for excessive wear and cordline wear. Replace the drive belt if necessary.
Hint: Cracks on the rib side of a belt are considered acceptable. If missing chunks from the
ribs are found on the drive belt, it should be replaced.
2. Bleed the power steering system
(1) Check the fluid level
(2) Jack up the front of the vehicle and make sure it is safe
(3) Rotate the steering wheel
a. With the engine off, turn the steering wheel from LH limit position to RH limit position several
times
(4) Release the jack and lower the vehicle
(5) Start the engine, run the engine at idle for a few minutes
(6) Turn the steering wheel to left or right limit position and keep it there for 2 - 3 seconds, then turn the
steering wheel to the opposite limit position and keep it there for 2 - 3 seconds. Repeat it several
times.
(7) Shut off the engine, check for foaming or emulsification in the reservoir. If there is foaming or
emulsification, bleed power steering system repeatedly
(8) Check the fluid level and for leakage
2. Check the fluid level
(1) Park the vehicle on a level surface
(2) With the engine stopped, check the fluid level in the reservoir. Add power steering fluid AT F
DEXRON if necessary.
Hint: the fluid level should be within the range of lowest level and highest level
(3) Check for foaming or emulsification, if there is, drain the power steering systemNormalAbnormal

torque: 27~39N.m. Install the cotter pin, make sure of the correct installation
(7) Add appropriate amount of specified power steering fluid, bleed the power steering sys-
tem
(8) Check the power steering pipeline system for leakage
(9) Check the front wheel alignment and front wheel left and right limit turn angle, adjust the
toe in if necessary and tighten the tie rod lock nut
(10)Check the position of the steering wheel. It is required that the steering wheel spokes
are basically symmetrical when the vehicle is driven straight ahead, reassemble the steering
wheel if necessary
197III. WIPER SWITCH ASSEMBLY REPLACEMENT1. DETACH STEERING WHEEL ASSEMBLY

(b) Remove the 2 tapping screws that are for mounting the wiper switch, take out the wiper switch from the
bracket of the combination switch.IV. WASHER NOZZLEADJUSTMENT
1. INSPECT WASHER NOZZLE
(a) Start the engine, check if the position where the washer fluid from the nozzle sprays the windshield is in
the central or upper of the area wiped by the blades.
(b) Change the direction (horizontal) of the nozzle hole to adjust the point where washer fluid sprays the
windshield.
259III. DIAGNOSIS OF CRASHED VEHICLEsWhether the SRS is deployed or not, the checking and maintenance of the crashed vehicle shall be carried
out according to the following procedures.
1. Check the diagnostic signal of ECU
(1) Connect the check connector of the Hi-DS T Scan Meter.
(2) Read out the diagnostic results from Hi-DS T Scan Meter.
2. Repair procedures
(1) When the SRS is deployed, the following parts shall be renewed.
1Passenger airbag assembly.
2ECU.
3Driver airbag assembly.
Check the following parts, if abnormal, replace with new ones.
1Clock spring.
2Steering wheel, steering column and steering lower shaft
component.
The installation status of driver airbag assembly in relation to steering wheel.
1Check and see if there is abnormal noise in the steering wheel, the action of the same is good,
or the clearance is normal.
2Check the union joint of the wire harness for damage and the terminal for distortion.
3. ECU
(1) Check the brackets of the ECU Case for recess, crack, distortion, etc.
(2) Check the union joint for damage and terminal for distortion.
(3) Check the installation status of he ECU brackets
1Check the hood for recess, crack, distortion, etc.
2Check the union joint for damage, terminal for distortion
and wire harness for seizure.
3Check the case of the gas generator for recess,
crack and distortion.NOTICE
Due to shock, when the battery power
supply is insufficient, the scan Meter
cannot communicate with ECU, the
instrument panel wire harness shall be
checked and maintained or external
power source shall be used.
260(4) Check the installation status of the airbag assembly.
4. Driver airbag assembly (see the figure below)
5. Clock spring (see the figure on the right)
(1) Check the union joint and protecting tube for damage and the
terminal for distortion.
(2) Check the case for distortion.
6. Steering wheel, steering column and steering lower shaft component.
(1) Check the installation status of driver airbag assembly.
(2) Check the steering wheel for any abnormal noise and see if the
clearance is normal.
7. Check the wire harness joint (instrument panel wire harness).
8. Check and see if the wire harness is securely installed, if the joint is damaged and if the terminal is
distorted.NOTICE
1. Work must be started 60s after the negative (-) terminal cable is disconnected from battery. The
disconnected negative (-) terminal cable shall be protected with insulating tape for insulation.
2. Airbag assembly and clock spring shall not be removed or repaired. They shall be replaced if there is
any trouble.
3. Pay enough attention to airbag assembly and clock spring when using, avoiding dropping them onto the
ground or into water or oil. In addition, if there is any pitting, crack or distortion on them, replace with
new ones.
4. When an airbag is deployed, the deployed surface should face up. It should be kept on a flat surface
without any other items on it.
5. Don’t keep an airbag in a place where the temperature is higher than 93°C.
6. When an airbag is deployed, it shall be replaced with a new one; simultaneously, check the clock spring,
and replace it with a new one if found abnormal.
