7. Disconnect the horn switch connector and spiral cable connec-
tor.
NOTE:
Disconnect the horn switch connector, and then the spiral cable
connector.
CAUTION:
Do not tap or bump the steering wheel.
8. Loosen screws. While pushing upper plastic tab, remove spiral cable.
INSTALLATION
Install in the reverse order of removal.
CAUTION:

If it is mounted in the inappropriate position, spiral cable
may be cut when performing steering operation.

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 counterclock-
wise about 2.5 turns from the right end position.

Do not twist spiral cable freely or excessively after it
becomes tight (doing so may cause the cable to be torn
off).

Secure air bag harness to the harness fixing hook.

Check SRS air bag warning lamp to make sure that the sys-
tem works normally after finishing work.

If SRS air bag warning lamp indicates a DTC exists, reset
with self-diagnosis and erase the memory using CONSULT-
II.

After the operation above, if SRS air bag warning lamp still
shows a non-standard condition, perform system trouble
diagnosis again, and repair or replace the indicated compo-
nent. Refer to SRS-16, "
SRS Operation Check" .

Air Bag Deployment Tool Lamp Illumination Chart (Battery Connected)
*: If this lamp glows red, the tool is connected to the battery incorrectly. Reverse the connections and make sure the lamp glows green.
DEPLOYMENT PROCEDURES FOR AIR BAG MODULE (OUTSIDE OF VEHICLE)
Unless the vehicle is being scrapped, deploying the air bag in the
vehicle is not recommended. This may cause damage to the vehicle
interior.
Anchor air bag module bracket (SST: KV99105300) in a vise
secured to a firm foundation during deployment.
Deployment of Driver Air Bag Module (Outside of Vehicle)
1. Using wire, secure air bag module to air bag module bracket
(SST: KV99105300) at two places.
CAUTION:
Use wire of at least 1 mm (0.04 in) diameter.
2. Firmly secure air bag module bracket (SST: KV99105300) with
air bag module attached, in a vise.
3. Connect deployment tool adapter (SST: KV99109700) to air bag
module connector and deployment tool connector (SST:
KV99106400).
4. Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
5. The lamp on the right side of the tool, marked “deployment tool
power”, should glow green, not red.
6. Press the button on the deployment tool. The left side lamp on
the tool, marked “air bag connector voltage”, will illuminate and
the air bag module will deploy.
CAUTION:
When deploying the driver air bag module, stand at least 5 m
(16 ft) away from the air bag module.

Deployment of Front Passenger Air Bag Module (Outside of Vehicle)
1. Firmly secure air bag module bracket (SST: KV99105300) in a
vise.
2. Match the hole in air bag module bracket (held in vise) and front
passenger air bag module and fix them with one bolt [M8 × 25 -
30 mm (0.98 - 1.18 in)].
CAUTION:
If a gap exists between front passenger air bag module and
air bag module bracket, use a piece of wooden block
inserted in the gap to stabilize the air bag module.
3. Connect deployment tool (SST: KV99106400) and deployment
tool adapter (SST: KV99108300) to front passenger air bag
module connector.
