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.

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 limited num-
ber 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.

8. Install dynamic damper.
9. Position air bag module and tighten with new special bolts.
+Always service the air bag module from the side.
10. Connect air bag module connector.
11. Install steering switches and lids.
12. Perform self-diagnosis to ensure entire SRS operates prop-
erly. (Use CONSULT-II or warning lamp check.)
Before performing self-diagnosis, connect both battery
cables.
13. Turn steering wheel to the left end and then to the right end
fully to make sure that spiral cable is set in the neutral posi-
tion.
If air bag warning lamp blinks or stays ON (at the User
mode), it shows the spiral cable may be snapped due to its
improper position. Perform self-diagnosis again (use CON-
SULT-II or warning lamp). If a malfunction is detected,
replace the spiral cable with a new one.
14. Perform self-diagnosis again to check that no malfunction is
detected.

Disposal of Air Bag Module and Seat Belt
Pre-tensioner
+Before disposing of air bag module and seat belt pre-tensioner, or vehicles equipped with such systems,
deploy the systems. If such systems have already been deployed due to an accident, dispose of them
as indicated in ªDISPOSING OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONERº (RS-2013).
+When deploying the air bag module and seat belt pre-tensioner, always use the Special Service Tool;
Deployment tool KV99106400.
+When deploying the air bag module and seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
deployment component.
+When deploying air bag module and seat belt pre-tensioner, a fairly loud noise is made, followed by
smoke being released. The smoke is not poisonous, however, be careful not to inhale smoke since it
irritates the throat and can cause choking.
+Always activate one air bag module at a time.
+Due to heat, leave air bag module unattended for more than 30 minutes after deployment. Also leave
seat belt pre-tensioner unattended for move than 10 minutes after deployment.
+Be sure to wear gloves when handling a deployed air bag module and seat belt pre-tensioner.
+Never apply water to the deployed air bag module and seat belt pre-tensioner.
+Wash your hands clean after finishing work.
+Place the vehicle outdoors with an open space of at least 6 m (20 ft) on all sides when deploying air
bag module and seat belt pre-tensioner while mounted in vehicle.
+Use a voltmeter to make sure the vehicle battery is fully charged.
+Do not dispose of the air bag module and seat belt pre-tensioner un-deployed.
CHECKING DEPLOYMENT TOOL
Connecting to battery
CAUTION:
The battery must show voltage of 9.6V or more.
Remove the battery from the vehicle and place it on dry wood
blocks approximately 5 m (16 ft) away from the vehicle.
+Wait 3 minutes after the vehicle battery is disconnected
before proceeding.
+Connect red clip of deployment tool to battery positive termi-
nal and black clip to negative terminal.
Make sure the polarity is correct. The right side lamp in the
tool, marked ªdeployment tool powerº, should glow with a
green light. If the right side lamp glows red, reverse the
connections to the battery.

Deployment of passenger air bag module (outside of
vehicle)
1. Make an 8.5 mm (0.335 in) diameter hole in air bag module
bracket (SST: KV99105300) at the position shown in figure
at left.
2. Firmly secure air bag module bracket (SST: KV99105300) in
a vise.
3. Match the two holes in air bag module bracket (held in vise)
and passenger air bag module and fix them with two bolts
[M8 x 25 - 30 mm (0.98 - 1.18 in)].
CAUTION:
If a gap exists between passenger air bag module and air
bag module bracket, use a piece of wood inserted in the gap
to stabilize the air bag module.
