functioning normally.
NOTE: If the airbag indicator lamp fails to light, or
lights and stays on, there is an airbag system mal-
function. Refer to the proper Diagnostic Procedures
manual to diagnose the problem.

SERVICE PROCEDURES

AIRBAG SYSTEM

NON-DEPLOYED
At no time should any source of electricity be per-
mitted near the inflator on the back of an airbag
module. When carrying a non-deployed airbag mod-
ule, the trim cover or airbag side of the module
should be pointed away from the body to minimize
injury in the event of an accidental deployment. If
the module is placed on a bench or any other surface,
the trim cover or airbag side of the module should be
face up to minimize movement in the event of an
accidental deployment.
In addition, the airbag system should be disarmed
whenever any steering wheel, steering column, or
instrument panel components require diagnosis or
service. Failure to observe this warning could result
in accidental airbag deployment and possible per-
sonal injury. Refer to Group 8E - Instrument Panel
Systems for additional service procedures on the
instrument panel. Refer to Group 19 - Steering for
16–WAY DATA LINK CONNECTOR BOTTOM OF INSTRU- MENT PANEL
additional service procedures on the steering wheel
and steering column.
DEPLOYED
Any vehicle which is to be returned to use after an
airbag deployment, must have both airbag modules,
the clockspring, the instrument panel top pad, and
the passenger side airbag rear mounting bracket
replaced. These components will be damaged or
weakened as a result of an airbag deployment, which
may or may not be obvious during a visual inspec-
tion, and are not intended for reuse.
Other vehicle components
inspected, but are to be replaced only as required by
the extent of the visible damage incurred.

CLEANUP PROCEDURE

Following an airbag system deployment, the vehi-
cle interior will contain a powdery residue. This res-
idue is primarily sodium bicarbonate (baking soda),
used as an airbag cushion lubricant. However, there
will also be traces of sodium hydroxide powder, a
chemical by-product of the generant used for airbag
deployment. Since this powder can irritate the skin,
eyes, nose, or throat, be sure to wear safety glasses,
rubber gloves, and a long-sleeved shirt during
cleanup (Fig. 2).
Fig. 2 Wear Safety Glasses and Rubber Gloves
WARNING: 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 PHYSI-
CIAN.
Begin the cleanup by removing the airbag modules
from the vehicle as described in this group.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Clean from outside the
