DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER

DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER

Caution for Air Bag Module and Seat Belt Pre-tensioner

INFOID:0000000001404296

• 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 Disposing of Air Bag Module and Seat Belt Pre-tensioner.

• When deploying the air bag module and seat belt pre-tensioner,always use the Special Service Tool; Deploy-

ment tool (SST: 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 fairlyloud 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 more than 10 minutes after deployment.

• 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 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 volt meter to make sure the vehicle battery is fully charged.
• Do not dispose of the air bag module and seat belt pre-tensioner undeployed.

CHECKING DEPLOYMENT TOOL

Connecting to Battery

CAUTION:

The battery must show voltage of 9.6 V 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 pro-

ceeding.

• Connect red clip of deployment tool (A) to battery positive terminal

and black clip to negative terminal.

Check that the polarity is correct. The right side lamp in the
tool, marked “deployment tool power”, should glow with a
green light. If the right side lamp glows red, reverse the connec-
tions  to the battery.

Deployment Tool Check

Press the deployment tool switch (C) to the ON position. The left
side lamp in the tool, marked “air bag connector voltage” should illu-
minate (B). If it does not illuminate, replace the deployment tool (A).

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) (A) in a vice
secured to a firm foundation deployment.

2.

Using wire (B), secure air bag module (1) to air bag module
bracket (SST: KV99105300) (A) at four places.

CAUTION:

• Use wire of at least 1 mm (0.04 in) diameter.
• If a gap exists between air bag module and air bag module

bracket, use a piece of wood (D) inserted in the gap to sta-
bilize the air bag module.

3.

Firmly secure air bag module bracket (SST: KV99105300) (A)
with air bag module attached, in a vise (C).

4.

Connect deployment tool adapter (SST: KV99110500) (B) to air
bag module (1) and deployment tool connector (SST:
KV99106400) (A).

5.

Connect red clip of deployment tool (A) to battery positive termi-
nal and black clip to negative terminal (B).

6.

The lamp on the right side of the tool, marked “deployment tool
power”, should glow green, not red.

7.

Press the button on the deployment tool (A). The left side lamp
