Airbag Squib Status
Multistage airbags with multiple initiators (squibs) must be checked to determine that all squibs were used during the deployment event. The driver and passenger airbags in this vehicle are deployed by electrical signals generated by the Occupant Restraint Controller (ORC) through the driver or passenger squib 1 and squib 2 circuits to the two initiators in the airbag inflators. Typically, both initiators are used and all potentially hazardous chemicals are burned during an airbag deployment event. However, it is possible for only one initiator to be used due to an airbag system fault; therefore, it is always necessary to confirm that both initiators have been used in order to avoid the improper handling or disposal of potentially live pyrotechnic or hazardous materials. The following procedure should be performed using a diagnostic scan tool to verify the status of both airbag squibs before either deployed airbag is removed from the vehicle for disposal.
- Be certain that the diagnostic scan tool contains the latest version of the proper diagnostic software. Connect the scan tool to the 16-way Data Link Connector (DLC). The DLC is located on the driver side lower edge of the instrument panel, outboard of the steering column.
- Turn the ignition switch to the ON position.
- Using the scan tool, read and record the active (current) Diagnostic Trouble Code (DTC) data.
Using the active DTC information, refer to the AIRBAG SQUIB STATUS table to determine the status of both driver and passenger airbag squibs.
| AIRBAG SQUIB STATUS | ||
|---|---|---|
| IF THE ACTIVE DTC IS: | CONDITIONS | SQUIB STATUS |
| Driver or Passenger Squib 1 open | AND the stored DTC minutes for both Driver or Passenger squibs are within 15 minutes of each other | Both Squib 1 and 2 were used. |
| Driver or Passenger Squib 2 open | ||
| Driver or Passenger Squib 1 open | AND the stored DTC minutes for Driver or Passenger Squib 2 open is GREATER than the stored DTC minutes for Driver or Passenger Squib 1 by 15 minutes or more | Squib 1 was used; Squib 2 is live. |
| Driver or Passenger Squib 2 open | ||
| Driver or Passenger Squib 1 open | AND the stored DTC minutes for Driver or Passenger Squib 1 open is GREATER than the stored DTC minutes for Driver or Passenger Squib 2 by 15 minutes or more | Squib 1 is live; Squib 2 was used. |
| Driver or Passenger Squib 2 open | ||
| Driver or Passenger Squib 1 open | AND Driver or Passenger Squib 2 open is NOT an active code | Squib 1 was used; Squib 2 is live. |
| Driver or Passenger Squib 2 open | AND Driver or Passenger Squib 1 open is NOT an active code | Squib 1 is live; Squib 2 was used. |
