Operation CHARM: Car repair manuals for everyone.

Simultaneously Deploying Airbags and Seat Belt Tensioners

Before scrapping any airbags or seat belt tensioners (including those in a whole car to be scrapped), the airbags must be deployed and the seat belt tensioners must be triggered. If the car is still within the warranty period, before deploying the airbag(s) or triggering the seat belt tensioners, the Acura District Technical Manager must give approval and/or special instruction. Only after the airbags are already deployed or the seat belt tensioners are triggered (as the result of vehicle collision, for example), can the normal scrapping procedure be done.

If the airbags or the seat belt tensioners appear intact (not deployed or triggered), treat them with extreme caution.

Follow the procedure, described below.

Simultaneously Deploying Airbag(s) and Triggering Seat Belt Tensioners

1. Disconnect both the negative cable and positive cable from the battery.
2. Confirm that the special tool is functioning properly by following the check procedure on the label of the tool.


Simultaneously Deploying Airbag(s) And Triggering Seat Belt Tensioners:





3. Disconnect the SRS main harness 18P connector from the SRS unit.
4. Cut the eight wires at the SRS main harness 18P connector four on each side as shown. Strip the end of the wires, then twist them together to make each set of four wires into one.
5. Connect the alligator clips of the deployment tool to the ends of the twisted wires.


Simultaneously Deploying Airbag(s) And Triggering Seat Belt Tensioners:





6. Buckle the seat belt, then pull out about two inches of slack, make a loop with it, and hold the loop in place with a clip as shown.
7. Repeat step 6 on the other front belt.
8. Connect a 12 volt battery to the tool:
- If the green light on the tool comes on, an igniter circuit is defective. Go to Damaged Airbag or Tensioner Special Procedure.
- If the red light on the tool comes on, the system is ready.

9. Push the tool's deployment switch. The airbags should deploy (deployment is both highly audible and visible a loud noise and rapid inflation of the bags, followed by slow deflation).
- The seat belt tensioners should take up the slack (pop the clips off the belts), and lock the belts in retracted positions.
- If the airbags are deployed, the tensioners are triggered, and the green light on the tool comes on, continue with this procedure.
- If an airbag doesn't deploy or a tensioner isn't triggered, yet the green light comes on, an igniter is defective. Go to Damaged Airbag or Tensioner Special Procedure.

WARNING: During airbag deployment and tensioner activation the airbag and tensioner assemblies can become hot enough to burn you. Wait thirty minutes after activation before touching them.

10. Dispose of the complete airbag and tensioner assembly. No part of them can be reused.
