Caution for Air Bag Module and Seat Belt Pre-tensioner EHS000DE
●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 SRS-46, "
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;
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 irri-
tates 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.
●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 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
Press 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.
