are used by the supplemental restraint system to monitor or confirm the direction and severity of a vehicle impact,
improper orientation or insecure fastening of these components may cause airbags not to deploy when required, or
to deploy when not required.
All other vehicle components should be closely inspected following any supplemental restraint deployment, but are
to be replaced only as required by the extent of the visible damage incurred.
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 model 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 per-
formed using a diagnostic scan tool to verify the status of both airbag squibs before either deployed airbag is
removed from the vehicle for disposal.
CAUTION: Deployed front airbags having two initiators (squibs) in the airbag inflator may or may not have
live pyrotechnic material within the inflator. Do not dispose of these airbags unless you are sure of com-
plete deployment. Refer to the Hazardous Substance Control System for proper disposal procedures. Dis-
pose of all non-deployed and deployed airbags and seat belt tensioners in a manner consistent with state,
provincial, local, and federal regulations.
1. 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.
2. Turn the ignition switch to the On position.
3. 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/or 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.
If none of the Driver or Passenger Squib 1 or 2 open are active codes, the status of the airbag squibs is unknown.
In this case the airbag should be handled and disposed of as if the squibs were both live.
