Driver-side Air Bag Module

WARNING:

The driver-side air bag module is a dual inflator type. If one inflator is forced to operate (deploy), the other may operate (deploy) accidentally. To prevent injury while disposing of the air bag module, make sure to operate (deploy) both driver-side air bag module inflators simultaneously, following the procedure below.

NOTE:

The SSTs, two types of adapter harnesses (for inflators No.1 and No.2) and two deployment tools are to be used to operate (deploy) the driver-side air bag module.

Remove the driver-side air bag module. (See DRIVER-SIDE AIR BAG MODULE REMOVAL [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .)
Wrap the wiring harness (cross section 1.25 mm ² {0.002 in ² } or more) at least four times around the position shown in the figure for the driver-side air bag module.

Connect the SST (Adapter harness) to the driver-side air bag module.

Fig 2: Connecting SST (Adapter Harness) To Driver-Side Air Bag Module
Place the driver-side air bag module on the center of the tire wheel with the padded surface facing up. To secure the air bag module to the tire wheel, wrap a wire (cross section 1.25 mm ² {0.002 in ² } or more) through the wheel and the bolt installation holes of the air bag module at least 4 times .

WARNING:
- If the air bag module is not properly installed to the tire wheel, serious injury may occur when the module is operated (deployed). When installing the air bag module to the tire wheel, make sure the padded surface is facing up.
Stack three tires without wheels on top of the tire with the driver-side air bag module, and then stack another tire with a wheel on the very top.

Secure the tires with wire.

Connect the SST (Deployment tool) to the SST (Adapter harness) .
Connect the SST (Deployment tool) to the battery. Connect the power supply red clip to the positive battery terminal, and the black clip to the negative battery terminal.
Verify that the red lamp on the SST (Deployment tool) is illuminated.
Verify that all persons are standing at least 6 m {20 ft} away from the vehicle.

Fig 6: Connecting SST (Deployment Tool) To SST (Adapter Harness)
Press the activation switch on the SST (Deployment tool) connected with 49 L066 002 (a yellow connector) of the SST (Adapter harness) , and after 3 s , press the activation switch on the other SST (Deployment tool) to operate (deploy) the air bag module (both inflators)

WARNING:
- Verify that air bag module operation (explosive) sound occurs twice. If no operation (explosive) sound was heard or a single operation (explosive) sound was heard, both inflators would not have operated (deployed) properly. This may cause serious injury if the air bag module operates (deploy) unexpectedly. If the two operation (explosive) sounds are not heard, perform Step 12 again. If a total of two operation (explosive) sounds cannot be verified even though Step 12 is performed again, leave the air bag module alone for 30 min or more before approaching it again.
- The air bag module is very hot immediately after it is operated (deployed). You can be burned. Do not touch the air bag module for at least 15 min after deployment.
Disconnect the SST (Deployment tool) from the SST (Adapter harness) .
