Caution for Air Bag Module and Seat Belt Pre-tensioner
EHS00139
●
Before disposing of air bag module, seat belt pre-tensioner or vehicle equipped with such systems, deploy
the systems. If such systems have already been deployed due to an accident, dispose of them as indi-
cated in “
SRS-67, "DISPOSING OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER"
.
●
When deploying the air bag module or seat belt pre-tensioner, always use the Special Service Tool
Deployment tool [KV99106400 (J-38381)].
●
When deploying the air bag module or seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
component being deployed.
●
When deploying air bag module or 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.
●
Only deploy one air bag module or seat belt pre-tensioner at a time.
●
Due to heat, leave deployed air bag module unattended for at least 30 minutes after deployment. Leave
deployed seat belt pre-tensioner unattended for at least 10 minutes after deployment.
●
Be sure to wear gloves when handling a deployed air bag module or seat belt pre-tensioner.
●
Never apply water to the deployed air bag module or seat belt pre-tensioner.
●
Wash your hands thoroughly 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 or 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 or seat belt pre-tensioner undeployed.
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 terminal
and black clip to negative terminal.
Make sure 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 connections
to the battery.
Deployment Tool Check
Place the deployment tool switch to the ON position. The left side
lamp in the tool, marked “air bag connector voltage” should illumi-
nate. If it does not illuminate, replace the tool.

Using wire, secure air bag module to the Tool at two places.
CAUTION:
Use wire of at least 1 mm (0.04 in) diameter.
2.
Firmly secure Tool with air bag module attached, in a vise.
3.
Connect deployment Tool A to air bag module connector using
Tool B.
4.
Connect red clip of 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.
