DISPOSAL

1. Precautions for handling the device

WARNING:

The following service operations include the works which may affect the SRS airbag system. Before starting work, always be sure to confirm the precautions related to the SRS airbag system. (Refer to

)

NOTE:

The following procedure is for LH side. Unless otherwise specified, perform the same procedures for the RH side.

2. Disposal of the side airbag module LH (for module only)

WARNING:

·Perform the operation outdoors on a level surface where safety can be ensured. Avoid performing the operation in residential and similar areas as much as possible.
·Before operating, notify people in the surrounding area because the airbag operation makes a loud noise.

(1) Removal of the side airbag module LH (Refer to

)

NOTE:

Refer to the procedure until removal of the side airbag module LH.

(2) Securing of side airbag module LH

(a) Install two mounting nuts to the side airbag module LH.

(b) Using wiring harnesses (with a core of 1.25 mm² {0.00194 sq in} or more) (A), secure the side airbag module LH to a tire.

*2	Core
*a	Secure the airbag with the deploying side facing the center
*b	Use three wiring harnesses as a unit (without slack)

WARNING:

Strictly follow the two instructions below. Failure to do so may result in serious damage suffered by flying debris of the deployed side airbag module LH or tire, etc.

·When activating the side airbag module LH, a force of approx. 1 t is applied on the wiring harnesses. Therefore, secure the module tightly with triple wiring harnesses without slack.
·As shown in the figure, be sure to install the side airbag module LH with the deploying side facing the center of the tire.

CAUTION:

Use waste tires for disposal operation.

(3) Activation of side airbag module LH

(a) Connect the following SSTs together.

SST 98299PA030 (airbag deployment tool) 98299CA000 (test harness adapter AR)

*a	Short the circuit

(b) Short the alligator clip and the terminal of SST (98299PA030).

CAUTION:

Lock the SST (98299CA000) securely.

(d) As shown in the figure, place two tires on top of each other, and then pile the tire-mounted side airbag module LH, a tire, and a tire with disc wheel in that order.

(e) Using a wire with a diameter of 1.8 mm {0.07 in} or more (usual iron wire for general-purpose: corresponding to JIS SWM-B), wrap the entire tires twice or more without slack to secure them tightly.

CAUTION:

·Secure them so that the total load capacity becomes 1 t or more.
·Use waste tires and disc wheels for disposal operation.

(f) Fully expand the SST (98299PA030) from the side airbag module LH and place the battery 5 m {16.4 ft} or more away from the tires.
