57.INSTALL SPIRAL CABLE SUB±ASSY (See page 60±26)
58. CENTER SPIRAL CABLE
(a) Check that the front wheels are facing straight ahead.
(b) Turn the cable counterclockwise by hand until it becomesharder to turn.
(c) Then rotate the cable clockwise about 2.5 turns to align the marks.
HINT:
The cable will rotate about 2.5 turns to either left or right of the
center.
59. INSTALL STEERING WHEEL ASSY
(a) Align matchmarks on the steering wheel and main shaft assembly.
(b) Install the steering wheel set nut. Torque: 50 N´m (510 kgf´cm, 37 ft´lbf)
(c) Connect the connector.
60. INSTALL HORN BUTTON ASSY
NOTICE:

Never use airbag parts from another vehicle. When
replacing parts, replace with new ones.

Make sure the horn button assy is installed with the
specified torque.

If the horn button assy has been dropped, or there are
cracks, dents or other defects in the case or connec-
tor, replace the horn button assy with a new one.

When installing the horn button assy, take care that
the wirings do not interfere with other parts and that
they are not pinched between other parts.
(a) Connect the terminal.
(b) Connect the airbag connector.
(c) Install the steering horn button assy after confirming that the circumference groove of the torx screws is caught on
the screw case.
(d) Using a torx socket wrench, torque the 2 screws. Torque: 8.8 N´m (90 kgf´cm, 78 in.´lbf)

ON±VEHICLE INSPECTION
1. INSPECT AIR CONDITIONER PRESSURE SENSOR
(a) Disconnect the pressure SW connector.
(b)Install the manifold gauge set (See page 55±38).
(c) Connect the positive (+) lead from the three 1.5 V dry cell
batteries to terminal 3 and negative (±) lead to terminal 1.
(d) Check the voltage between terminals 2 and 1 of pressure sensor.
Standard:
The voltage varies with on the refrigerant pressure as
shown in the chart.
2. INSPECT AIR CONDITIONING CONTROL ASSY
(a) Disconnect the connector from air conditioning control assy and inspect the connec\
tor on wire harness side, as shown in the table.
