+If clearance exceeds the limit, or any flaws or seizures are
found on inner surface of cylinder, horn or bore the appli-
cable cylinder.
Piston outer diameter
Use micrometer to measure piston skirt outer diameter.
Measurement position:
10 mm (0.39 in) upper from the lower end of pis-
ton
Standard:
95.950 - 95.980 mm (3.7776 - 3.7787 in) dia.
Calculation of piston to piston bore clearance
+Calculate using piston skirt outer diameter and cylinder inner
diameter (direction X, position B).
Clearance = Cylinder inner diameter þ Piston skirt outer
diameter
Specifications at room temperature [20ÉC (68ÉF)]:
0.040 - 0.060 mm (0.0016 - 0.0024 in)
+If out of specification, replace piston and piston pin assem-
bly.
SELECTIVE PISTON COMBINATION
When using new cylinder block
+Confirm cylinder bore grade (1, 2, 3) on left upper surface of
cylinder block, and refer to ªSelective combination chartº
below to select appropriate piston.
+Part No. is given to a piston and piston pin as a set.
When re-using an old cylinder block
1. Measure cylinder block bore inner diameter.
2. Referring to ªCylinder block bore inner diameterº in ªSelec-
tive combination chartº, select appropriate piston according
to cylinder bore grade.

CAUTION:
+Before servicing SRS, turn the ignition switch OFF, dis-
connect both battery cables and wait at least 3 minutes.
+Always work from the side of air bag module.
1. Remove lower lid from steering wheel, and disconnect air
bag module connector.
2. Remove side lid, ASCD steering switch and audio steering
switch (only on models for the Middle East). Using the
TAMPER RESISTANT TORX (Size T50), remove left and
right special bolts. Air bag module can then be removed.
CAUTION:
+Always place air bag module with pad side facing
upward.
+Do not attempt to disassemble air bag module.
+The special bolts are coated with bonding agent. Do not
use old bolts after removal; replace with new ones.
+Do not insert any foreign objects (screwdriver, etc.) into
air bag module connector.
+Replace air bag module if it has been dropped or sus-
tained an impact.
+Do not expose the air bag module to temperatures
exceeding 90ÉC (194ÉF).
+Do not allow oil, grease or water to come in contact with
the air bag module.
3. Set steering wheel in the neutral position.
4. Disconnect horn connector and remove nuts.
5. Remove dynamic damper. Then using steering wheel puller,
remove steering wheel. Be careful not to over-tighten puller
bolt on steering wheel.
CAUTION:
+Do not tap or bump the steering wheel.
6. Remove steering column cover.

7. Remove the four screws. Then unlock the spiral cable con-
nector and disconnect connector. The spiral cable can then
be removed.
CAUTION:
+Do not attempt to disassemble spiral cable.
+Do not apply lubricant to the spiral cable.
Installation Ð Driver Air Bag Module and
Spiral Cable
1. Set the front wheels in the straight-ahead position.
2. Connect spiral cable connector. Then, lock the connector
and tighten with screws. Install steering column cover.
3. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left about 2.5
revolutions from the right end position. Align the two marks
(
,
m).
CAUTION:
+The spiral cable may snap due to steering operation if
the cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the lim-
ited number of turns.
The spiral cable can be turned up to about 2.5 turns from
the neutral position to both the right and left.
4. Connect spiral cable connector and tighten with screws.
Install steering column cover.
5. Install steering wheel, setting spiral cable pin guide, and pull
spiral cable through.
6. Connect horn connector and engage spiral cable with pawls
in steering wheel. Move air bag module connector away from
steering wheel lower lid opening.
7. Tighten nut.
