AIRBAG SQUIB STATUS
IF the Active DTC is:
Conditions
Squib Status
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.
CLEANUP PROCEDURE
Following a supplemental restraint deployment, the
vehicle interior will contain a powdery residue. This
residue consists primarily of harmless particulate
by-products of the small pyrotechnic charge that ini-
tiates the propellant used to deploy a supplemental
restraint. However, this residue may also contain
traces of sodium hydroxide powder, a chemical
by-product of the propellant material that is used to
generate the inert gas that inflates the airbag. Since
sodium hydroxide powder can irritate the skin, eyes,
nose, or throat, be certain to wear safety glasses, rub-
ber gloves, and a long-sleeved shirt during cleanup.
WARNING: To avoid personal injury or death, if you experience skin irritation during cleanup, run cool water
over the affected area. Also, if you experience irritation of the nose or throat, exit the vehicle for fresh air
until the irritation ceases. If irritation continues, see a physician.
1. Begin the cleanup by using a vacuum cleaner to
remove any residual powder from the vehicle inte-
rior. Clean from outside the vehicle and work your
way inside, so that you avoid kneeling or sitting on
a non-cleaned area.
2. Be certain to vacuum the heater and air condition-
ing outlets as well. Run the heater and air condi-
tioner blower on the lowest speed setting and
vacuum any powder expelled from the outlets.
CAUTION: Deployed front airbags having two initi-
ators (squibs) in the airbag inflator may or may
not have live pyrotechnic material within the infla-
tor. Do not dispose of these airbags unless you
are sure of complete deployment. Refer to AIRBAG
SQUIB STATUS . All damaged, faulty, or non-de-
ployed supplemental restraints which are replaced
on vehicles are to be handled and disposed of properly. If an airbag or seat belt tensioner unit is faulty or
damaged and non-deployed, refer to the Hazardous Substance Control System for proper disposal. Be cer-
tain to dispose of all non-deployed and deployed supplemental restraints in a manner consistent with state,
provincial, local and federal regulations.

3. Next, remove the deployed supplemental restraints from the vehicle. Refer to the appropriate service removal
procedures.
4. You may need to vacuum the interior of the vehicle a second time to recover all of the powder.
SUPPLEMENTAL RESTRAINTS VERIFICATION TEST
The following procedure should be performed using a diagnostic scan tool to verify proper supplemental restraint
system operation following the service or replacement of any supplemental restraint system component. In addition,
if the vehicle is equipped with the Occupant Classification System and one of the passenger front seat supplemental
restraint components has been replaced, following successful completion of the supplemental restraint system ver-
ification test procedure, perform the Occupant Classification System Verification Test using a diagnostic scan tool.
Refer to the appropriate diagnostic procedures.
WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental
restraint system before attempting any steering wheel, steering column, airbag, occupant classification sys-
tem, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge
before performing further diagnosis or service. This is the only sure way to disable the supplemental
restraint system. Failure to take the proper precautions could result in accidental airbag deployment.
CAUTION: On vehicles equipped with the Occu-
pant Classification System (OCS), never replace
both the Airbag Control Module (ACM) and the
Occupant Classification Module (OCM) at the same
time. If both require replacement, replace the OCM
first. Then perform the supplemental restraint ver-
ification test including an ignition-On time of at
least one minute before replacing the ACM. Both
the ACM and the OCM store OCS calibration data,
which they transfer to one another during the first
minute of ignition-On time after one of them is
replaced. If both modules are replaced at the same
time, an irreversible fault will be set in both mod-
ules. If the data transfer is not allowed sufficient
time to complete between modules (at least one
minute of ignition-On), an irreversible fault will be
set in the module requiring the data.
1. During the following test, the battery negative cable
remains disconnected and isolated, as it was during the supplemental restraint system component removal and
installation procedures.
2. 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, inboard of the steering column.
3. Turn the ignition switch to the On position and exit the vehicle with the scan tool.
CAUTION: On vehicles equipped with the Occupant Classification System (OCS), if the Airbag Control Mod-
ule (ACM) or the Occupant Classification Module (OCM) have been replaced, leave the ignition switch in the
On position with the battery connected for at least one minute to allow the data transfer between the ACM
and the OCM to complete. If the data transfer is not allowed sufficient time to complete between modules
(at least one minute of ignition-On), an irreversible fault will be set in the module requiring the data.
4. Check to be certain that nobody is in the vehicle, then reconnect the battery negative cable.
5. Using the scan tool, read and record the active (current) Diagnostic Trouble Code (DTC) data.
6. Next, use the scan tool to read and record any stored (historical) DTC data.
7. If any DTC is found in Step 5 or Step 6, refer to the appropriate diagnostic information.

8. Use the scan tool to erase the stored DTC data. If any problems remain, the stored DTC data will not erase.
Refer to the appropriate diagnostic information to diagnose any stored DTC that will not erase. If the stored DTC
information is successfully erased, go to Step 9.
9. Turn the ignition switch to the Off position for about fifteen seconds, and then back to the On position. Observe
the airbag indicator in the instrument cluster. It should illuminate for six to eight seconds, and then go out. This
indicates that the supplemental restraint system is functioning normally and that the repairs are complete. If the
airbag indicator fails to light, or lights and stays on, there is still an active supplemental restraint system fault or
malfunction. Refer to the appropriate diagnostic information to diagnose the problem.
