5. Remove the power steering pump strap support assembly from the motor. Remove the 3 coupling bolts between
the power steering pump strap support assembly and the motor.
6. Install the power steering pump strap support assembly.
Fasten the steering pump strap support assembly on the motor, and tighten the M10 bolt with a torque of 45-
79N.m and M8 bolt with a torque of 16-26N.m.
7. Install the drive belt, and make sure the position is correct.
8. Install the high & lower pressure oil pipes of the power steering gear assembly.
(1) Connect the connector screw of the high and low pressure oil pipe to the steering gauge with a torque of
19-33N.m.
(2) Fasten the low pressure oil pipe on the body front baffle plate with clip.
(3) Connect the connector screw of the high pressure oil pipe to the power steering pump with a torque of
19-33N.m.
(4) Connect the connector screw of the low pressure oil pipe to the oil tank with a torque of 19-33N.
m.
9. Discharge all air in the power steering pipe system, and check the pipe system whether there is any leakage.
10. Check the oil reservoir inner fluid level Tips: The level shall stay between the lowest level and the highest level.
(3) Check whether there is any foam or emulsification. If so, discharge the power steering liquid.NormalAbnormal

3. Loosen the low pressure pipes
Loosen the low pressure pipes with special tool
4. Separate the tie rod from the steering knuckle
(1) Remove the cotter pin, loosen the groove type lock nut
(2) Separate the tie rod ball stud joint from the steering knuckle
taper hole5. Loosen the thread screw of the high and low pressure pipe on the steering gear assembly
6. Remove the boot and press plate
7. Disconnect the power steering gear assembly from the steering column
Remove the steering gear pinion shaft spline lock bolt on the universal joint yoke
8. Remove power steering gear assembly
Remove 2 steering gear assembly set bolts. Remove the power steering gear assembly
9. Installation is in the reverse order of the removal
Notice:
(1) Insert the steering gear pinion shaft spline into the spline hole of the universal joint yoke, make sure that
the positions of the notch of the steering gear pinion shaft and the lock bolt of the universal joint yoke are
correct
(2) Secure the power steering gear with 2 bolts, torque: 125~152N.m
(3) Tighten the steering gear pinion shaft spline lock bolt on the universal joint yoke, torque: 22~34N.m
(4) Install the boot and press plate
(5) Install the threaded connector of the power steering high and low pressure pipe to the power steering gear,
torque: 25~32N.m

ball stud pin and the steering knuckle is clean, tighten the slot nut, 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 system
(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

III. Wiper switch assemblyReplacement
1. Detach steering wheel assembly

(2) Change the height (left/right) of the nozzle hole to adjust the point where washer fluid sprays the windshield.Wiper and Washer System -Replacement and Adjustment5-25

5-62 (22) There are problems in the configuration of the airbag ECU (DTC 93D6)
When using the scan tool to test the airbag ECU, the DTC is 93D6, indicating that there are problems in the
configuration of the airbag ECU.
Step Operation Yes No
1 When using the scan tool to test the airbag ECU, is the DTC 93D6? Go to step 2 other
2Go to step 3
3 Go to step 4 Go to step 1
4 The fault has been removed, use the scan tool to eliminate the DTC.Check whether the configuration of the airbag ECU is consistent with the
actual on-board configuration?
After the troubleshooting, switch on the power supply, observe the status
of the warning light. The warning light shall goes off after lighting up for
4 seconds (self-check). (23) The impact signal output interface of the airbag ECU is short to ground or the impact output circuit is
disconnected. (DTC 93D7)
When using the scan tool to test the airbag ECU, the DTC is 93D7, indicating that the impact signal output
interface of the airbag ECU is short to ground or the impact output circuit is disconnected.IV. Diagnosis of collided vehicle No matter airbag is unfolded or folded, inspection and maintenance of collided vehicle should be performed
according to the following sequence.
1. Check ECU diagnosis signal.
(1) Connect scanner diagnosis joint
(2) Use scanner to read out diagnosis result.
2. Repair sequence
(1) when airbag is unfolded.
The following components should be replaced with new parts
a. Airbag assembly on passenger side
b. ECU
c. Airbag assembly on driver side
d. Seat belt with pretensionerNote:
due to impact, when battery power is insufficient, scanner can not communicate with ECU, now check and
service instrument board wire harness or use external power supply.SRS (Supplemental Restraint System)-SRS-General Information (2 ) Check the following components, if there is any abnormity, replace with new parts
a. Clock spring.
b. Steering wheel, steering column, lower steering shaft assembly
(3 ) The installation status of driver airbag assembly in relation to steering wheel
a. Check and see if there is abnormal noise in the steering wheel, the action of the same is good, or the
clearance is normal.
b. Check the connecter of the wire harness for damage and the terminal for distortion.
