GENERAL INFORMATION
SIACM will request that the airbag warning lamp
be turned on. The results of the system test are
transmitted on the PCI Bus to the ACM once each
second or on change in lamp state. If the warning
lamp status message from the either SIACM con-
tains a lamp on request, the ACM will set an active
DTC. At the same time as the DTC is set the ACM
sends a PCI Bus message to the mechanical instru-
ment cluster (MIC) requesting the airbag warning
lamp be turned on. Observe all ACM warning and
caution statements when servicing or handling the
SIACM. SIACM are not repairable and must be
replaced if they are dropped.
WARNING: THE AIRBAG SYSTEM IS A
SENSITIVE,
COMPLEX
MECHANICAL UNIT. BEFORE ATTEMPTING
TO DIAGNOSE OR SERVICE ANY AIRBAG
SYSTEM OR RELATED STEERING WHEEL,
STEERING
COLUMN,
PANEL COMPONENTS YOU MUST FIRST
DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. WAIT TWO
MINUTES FOR THE SYSTEM CAPACITOR TO
DISCHARGE BEFORE FURTHER SYSTEM
SERVICE. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIRBAG SYSTEM. FAILURE
TO DO THIS COULD RESULT IN ACCIDENTAL
AIRBAG
DEPLOYMENT
PERSONAL INJURY. NEVER STRIKE OR
KICK THE AIRBAG CONTROL MODULE, AS
IT CAN DAMAGE THE IMPACT SENSOR OR
AFFECT ITS CALIBRATION. IF AN AIRBAG

DROPPED DURING SERVICE, THE MODULE
MUST BE SCRAPPED AND REPLACED WITH
A NEW UNIT.
The airbag warning lamp is the only point at
which the customer can observe symptoms of a
system malfunction. Whenever the ignition key is
turned to the run or start position, the MIC per-
forms a lamp check by turning the airbag warning
indicator on for 6-8 seconds. After the lamp check, if
the indicator turns on, it means that the ACM has
checked the system and found it to be free of
discernible malfunctions. If the lamp remains on,
there could be an active fault in the system or the
MIC lamp circuit may be internally shorted to
ground. If the lamp comes on and stays on for a
period longer than 6-8 seconds then goes off, there
is usually an intermittent problem in the system.
3.1.7 SEAT AIRBAGS (SAB)
The left and right seat airbags are located in the
outboard end of the front seat backs. The airbag

module contains a bag, an inflator (a small canister
of highly compressed argon gas) and a mounting
bracket. The seat airbags cannot be repaired and
must be replaced if deployed or in any way dam-
aged. When supplied with the proper electrical
signal the inflator seals the hole in the airbag
cushion so it can discharge the compressed gas it
contains directly into the cushion. Upon deploy-
ment, the seat back trim cover will tear open and
allow the seat airbag to fully deploy between the
seat and the door.

3.1.8 DIAGNOSTIC TROUBLE CODES
Airbag diagnostic trouble codes consist of active
and stored codes. If more than one code exists,
diagnostic priority should be given to the active
codes. Each diagnostic trouble code is diagnosed by
following a specific testing procedure. The diagnos-
tic test procedures contain step-by-step instructions
for determining the cause of the trouble codes. It is
not necessary to perform all of the tests in this book
to diagnose an individual code. Always begin by
reading the diagnostic trouble codes using the
DRBIII . Always begin diagnostic with the Table of
Contents section 7.0. This will direct you to the
specific test(s) that must be performed. Active diag-
nostic trouble codes for the airbag system are not
permanent and will change the moment the reason
