When placing a live inflator module on a bench
or other surface, always face the bag and trim
cover up, away from the surface. This is neces­
sary so that a free space is provided to allow the
air bag to expand in the unlikely event of acci·
dental
deployment.
4. Steering wheel
• Refer to STEERING WHEEL REPLACEMENT in
Section 3F4.
5. Lighting switch (Combination switch)
• Disconnect the switch connector.
• Remove four screws.
• Remove the lighting switch together with SRS
coil assembly.
'\f CAUTION:
Do not remove SRS coil assembly from the com·
bination switch assembly.
E) INSTALLATION
To install, follow the removal steps in the reverse
order, noting the
following points.
1. Check to see if the vehicle is in the straight driving
condition and turn the rotary section of the SRS
coil assembly provided to the upper surface ofthe
lighting switch (combination switch) clockwise
fully until it stops. Then from where it stops, turn
it back about 3 rotations to set the alignment
marks together before installing the steering
wheel. (Fig. 8-83)

2. Tighten the steering shaft nut to the s ecified
torque.

3. When connect the double lock type of nflator
module connector, insert the connecto com­
pletely
and lock at outside. Imperfect locki g may
cause malfunction of SRS system circuit.
4. When installing the steering cowl, be sure o pass
the harnesses
through the route as show in the
illustration so that the starter switch, th com­
bination switch and the inflator module
will not get caught. (Fig. 8-84)

SPEEDOMETER (FIG. 8-346)
Fig. 8-346
The speedometer is made up
of the cross coil type
ammeter (movement)
that displays indications, the
stepper
motor that drives and adds up the odometer
and
trip meter, and the driving circuit (printed circuit
board) that makes exchanges between the
pulse sig­
nals and the current.
Also, the vehicle speed sensor, which is incorporated
into the speedometer, is activated
by receiving sig­
nals (vehicle speed) detected by the vehicle speed
sensor
installed to the transmission.
