Damaged Airbag or Tensioner Special Proce-

dure.

If an airbag or tensioner cannot be

deployed or triggered, it should not be treated as

normal scrap; it should still be considered a poten-

tially explosive device that can cause serious

injury.

1. If installed in a vehicle, follow the removal proce-

dures in this section.

2. Intertwine the stripped ends of the two airbag or ten-

sioner wires to make a short circuit.

3. Package the airbag or tensioner in exactly the same

packaging that the new replacement part came in.

4. Mark the outside of the box "DAMAGED AIRBAG

(or TENSIONER) NOT DEPLOYED" so it does not

get confused with your parts stock. If applicable,

also note on the box the VIN of the vehicle from

which it was removed.

5. Contact your Acura District Technical Manager for

how and where to return it for disposal.
Deployment Tool: Check Procedure.

1. Connect the yellow clips to both switch protector

handles on the tool; connect the tool to a battery.

2. Push the operation switch: green means the tool is

OK; red means the tool is faulty.

3. Disconnect the battery and the yellow clips.ProCarManuals.com

CAUTION:

Before installing the steering wheel, the front wheels

should be aligned straight ahead.

Be sure to install the harness wires so that they are

not pinched or interfering with other car parts.

After reassembly, confirm that the wheels are still

turned straight ahead and that steering wheel spoke

angle is correct. If minor spoke angle adjustment is

necessary, do so only by adjusting the tie-rods, not

by removing and repositioning the steering wheel.

1. Align the cancel sleeve grooves with the cable reel

projections.

4. Center the cable reel.

Do this by first rotating the cable reel clockwise un-

Then rotate it counterclockwise (approximately

two turns) until:

The yellow gear tooth lines up with the align-

ment mark on the cover.

The arrow mark on the cable reel label points

straight up.
