Caution for Air Bag Module and Seat Belt Pre-tensioner

INFOID:0000000003839142

Precaution for Work

• 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. Refer to 

SR-25, "Caution for 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;

Deployment tool (SST: KV99106400).

• When deploying the air bag module and seat belt pre-tensioner, stand at least 5.0 m (16.4 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 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 work is completed.
• Place the vehicle outdoors with an open space of at least 6.0 m (19.7 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.
• Never dispose of the air bag module and seat belt pre-tensioner that does not deploy.

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 5.0 m (16.4 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 illuminate with a
green light. If the right side lamp illuminates red, reverse the
connections 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).

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

CAUTION:

Use wire of at least 1.0 mm (0.039 in) diameter.

3.

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

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

5.

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