DESCRIPTION AND OPERATION
AIRBAG SYSTEM
DESCRIPTION
A dual front airbag system is standard factory-in-
stalled safety equipment on this model. The primary
passenger restraints in this vehicle are the standard
equipment factory-installed seat belts, which require
active use by the vehicle occupants. The airbag sys-
tem is a supplemental passive restraint that was
designed and is intended to enhance the protection
for the front seat occupants of the vehicle only when
used in conjunction with the seat belts. See the own-
er’s manual in the vehicle glove box for more infor-
mation on the features, use and operation of all of
the factory-installed passenger restraints, including
the airbag system.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service
procedures outlined can generally be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
The dual front airbag system consists of the follow-
ing components:
•
Airbag Control Module (ACM)
•
Airbag indicator lamp
•
Clockspring
•
Driver and passenger side airbag modules
(including the airbag inflators)
•
Driver and passenger side knee blockers
•
Wire harness and connections.
This group provides complete service information
for the ACM, both airbag modules, and the clock-
spring. Complete service information for the other
airbag system components can be located as follows:
•
Refer to Instrument Cluster in the proper sec-
tion of Group 8E - Instrument Panel Systems for
complete service information for the airbag indicator
lamp.
•
Refer to Knee Blocker in the Removal and
Installation section of Group 8E - Instrument Panel
Systems for complete service information on the
driver side knee blocker.
•
Refer to Glove Box in the Removal and Instal-
lation section of Group 8E - Instrument Panel Sys-
tems
for complete service information on the
passenger side knee blocker.
•
Refer to Airbag System in the Contents of
Group 8W - Wiring Diagrams for complete service
information and circuit diagrams for the airbag sys-
tem wiring components.
See the proper Diagnostic Procedures manual to
test or diagnose a problem with any component of
the airbag system.
OPERATION
The airbag system electrical circuits are continu-
ously monitored and controlled by a microprocessor
and software contained within the Airbag Control
