STEERING SYSTEM
PRECAUTION
1. HANDLING PRECAUTIONS ON STEERING SYSTEM
(a) Be careful to replace the parts properly because they could affect the performance of the steering sys-
tem and result in a driving hazard.
2. HANDLING PRECAUTIONS ON SRS AIRBAG SYSTEM
(a) The vehicle is equipped with SRS (Supplemental Restraint System) such as \
the driver airbag and front passenger airbag. Failure to carry out service operation in the correct sequence \
could cause the SRS
to unexpectedly deploy during servicing, possibly leading to a serious acc\
ident. Before servicing (in-
cluding removal or installation of parts, inspection or replacement), be sure \
to read the precautionary
notices in the supplemental restraint system (See page 60±1).
3. HANDLING PRECAUTIONS ON STEERING COLUMN
(a) Do not give an impact to the steering column assy, especially the motor and the torque sensor. If a great impact is given (dropping it to the floor, etc.), replace it with a new one.
(b) When removing the steering column assy, do not pull the harness.
(c) When having replaced the steering column assy and/or the ECU, calibrate the \
zero point of the steer- ing torque sensor.
(d) In the case of disconnecting a connector related to the power steering sys\
tem, turn the ignition switch ON, set the steering wheel in the straight±ahead position and turn th\
e ignition switch OFF before dis-
connecting the connector.
(e) In the case of connecting a connector related to the power steering system, make sure that the ignit\
ion switch is OFF at first. After connecting the connector, set the steering wheel assy in the straight±ahead
position, and then turn the ignition switch ON.
NOTICE:
Never turn on the ignition switch when the steering wheel assy is set in orde\
r than the straight±ahead
position.
(f) If the above operation is not done, the zero point of the steering torque \
sensor is shifted away from the proper position, making difference in the steering effort between right and left. If this happens, per-
form the zero point calibration of the steering torque sensor (See page 05±1042).

8. REMOVE CLUTCH DISC ASSY
NOTICE:
Keep the lining part of the clutch disc assy, the pressure plate and surface of the flywheel sub±assy
away from oil and foreign attachment.
9. INSPECT CLUTCH DISC ASSY
(a) Using vernier calipers, measure the rivet head depth.
Maximum rivet depth: 0.3 mm (0.012 in.)
Replace the clutch disc assy as necessary.
(b) Install the clutch disc assy to the transaxle assy.
NOTICE:
Take care not to insert the clutch disc assy in the wrong
direction.
(c) Using a dial gage, check the clutch disc assy runout.
Minimum runout: 0.8 mm (0.031 in.)
Replace the clutch disc assy as necessary.
10. INSPECT CLUTCH COVER ASSY
(a) Using vernier calipers, inspect the diaphragm spring for
the depth and width of wear.
Maximum:
A (Depth): 0.5 mm (0.020 in.)
B (Width): 6.0 mm (0.236 in.)
Replace the clutch cover assy as necessary.
11. INSPECT FLYWHEEL SUB±ASSY
(a) Using a dial gage, inspect the flywheel sub±assy runout.
Maximum runout: 0.1 mm (0.004 in.)

12. INSPECT CLUTCH RELEASE BEARING ASSY
(a) Turn the release bearing by hand while applying force in
the axial direction.
HINT:
The bearing is permanently lubricated and requires no cleaning
or lubrication.
Replace the release bearing assy as necessary.
13. INSTALL CLUTCH DISC ASSY
