Before performing pre-disposal deployment of any SRS part, review and closely follow all applicable environmental and hazardous material regulations. Pre-disposal deployment may be considered hazardous material treatment.

PROCEDURE

1. PRECAUTION

HINT:

When scrapping a vehicle equipped with an SRS or disposing of the curtain shield airbag assembly, be sure to deploy the airbag first in accordance with the following procedure. If any abnormality occurs with the airbag deployment, contact the Service Department of the distributor.

2. DISPOSE OF CURTAIN SHIELD AIRBAG ASSEMBLY (When Installed to Vehicle)

HINT:

Prepare a battery as the power source to deploy the airbag.

(a) Check the function of SST. Click here SST: 09082-00700

(b) Refer to Precaution.

Click here

(c) Disconnect the cable from the negative (-) battery terminal.

CAUTION:

Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

(d) Remove the roof headlining assembly.

(e) Disconnect the curtain shield airbag assembly connector.

(1) Using a screwdriver with its tip wrapped with protective tape, disconnect the airbag connector.

NOTICE:

When disconnecting any airbag connector, take care not to damage the airbag wire harness.

(f) Install SST.

CAUTION:

Check that there is no looseness in the curtain shield airbag assembly.

(1) After connecting the following SST to each other, connect them to the curtain shield airbag assembly. SST: 09082-00700 SST: 09082-00802 09082-10801 09082-20801 NOTICE: To avoid damaging the SST connector or wire harness, do not lock the secondary lock of the twin lock.

(2) Move SST at least 10 m (32.8 ft.) away from the rear side window of the vehicle.

*a Battery *b 10 m (32.8 ft.) or more

(3) Maintaining sufficient clearance for the SST wire harness in the rear side window, close all doors and windows of the vehicle.

NOTICE:

Take care not to damage the SST wire harness.

(4) Connect the red clip of SST to the positive (+) battery terminal and the black clip of SST to the negative (-) battery terminal.

(g) Deploy the airbag.

(1) Check that no one is inside the vehicle or within a 10 m (32.8 ft.) radius of the vehicle.

(2) Press the SST activation switch to deploy the airbag.

HINT:

The airbag is deployed as the LED of the SST activation switch comes on.

3. DISPOSE OF CURTAIN SHIELD AIRBAG ASSEMBLY (When not Installed to Vehicle)

NOTICE:

Be sure to perform the following procedure when deploying the airbag.

HINT:

Prepare a battery as the power source to deploy the airbag.

(a) Check the function of SST. Click here SST: 09082-00700

(b) Remove the curtain shield airbag assembly.

Click here

(c) Cut off the deployment section of the curtain shield airbag assembly.

(d) Using braided wire, tie down the curtain shield airbag assembly to an unneeded tire.

Wire:

Stripped Wire Cross Sectional Area

1.25 mm2 (0.0019 in.2) or more

CAUTION:

If the wire is too thin or an alternative object is used to tie down the curtain shield airbag assembly, it may snap when the airbag is deployed. Always use a wire for vehicle use with a cross sectional area of at least 1.25 mm2 (0.0019 in.2).

HINT:

To calculate the cross sectional area of the stripped wire:

Cross sectional area = 3.14 x (Diameter)2 / 4

(1) Position the curtain shield airbag assembly inside the tire as shown in the illustration. Minimum Tire Size: Width 185 mm (7.28 in.) Inner Diameter 360 mm (1.18 ft.) CAUTION: Make sure that the wires are tight. If there is slack in the wires, the curtain shield airbag assembly may break loose when the airbag is deployed. NOTICE: The tire may be damaged by the airbag deployment, so use an unneeded tire.

(e) Install SST.

(1) After connecting the following SST to each other, connect them to the curtain shield airbag assembly. SST: 09082-00802 09082-10801 09082-20801

(f) Place the tires.

CAUTION:

Do not face the deployment side of the curtain shield airbag assembly toward the ground.

(1) Place at least 2 tires under the tire to which the curtain shield airbag assembly is tied. Minimum Tire Size: Width 185 mm (7.28 in.) Inner Diameter 360 mm (1.18 ft.) NOTICE: Do not place the SST connector under the tire because it could be damaged.

*a Tires (2 or more) *b Inner Diameter *c Width

(2) Place at least 2 tires onto the tire to which the curtain shield airbag assembly is tied. The top tire should have a wheel installed.

NOTICE:

The wheel and tires may be damaged by the airbag deployment, so use an unneeded wheel and tires.

(3) Tie the tires together with 2 wires. CAUTION: Make sure that the wires are tight. Looseness in the wires will result in the tires breaking loose when the airbag is deployed.

(g) Install SST.

(1) Connect the SST connector. SST: 09082-00700 NOTICE: To avoid damaging the SST connector or wire harness, do not lock the secondary lock of the twin lock. Also, secure some slack for the SST wire harness inside the tire.

(2) Check that no one is within a 10 m (32.8 ft.) radius of the tire to which the curtain shield airbag assembly is tied.

(3) Press the SST activation switch to deploy the airbag.

CAUTION:

Before deployment, make sure that no one is near the airbag.

HINT:

The airbag is deployed as the LED of the SST activation switch comes on.
