DEFINITIONS
AIR BAG -An inflatable cloth cushion designed to
deploy in certain frontal crashes. It supplements the
protection offered by the seat belts by distributing the
impact load more evenly over the vehicle occupant's
head and torso.
ASYNCHRONOUS -Performed in a non-periodic
fashion,i.e.no defined time or interval.
B+-Battery voltage, the voltage available at the battery
at the time of the indicated measurement. With the key
"ON" and the engine not running, the system voltage will
likely be between 12 and 12.5 volts. At idle the voltage
may be 14 to 16 volts. The voltage could be as low as 1
0
volts during engine cranking.
BULB
CHECK-The DERM will cause the "AIR BAG"
warning lamp to flash seven times and then go "OFF"
whenever the ignition switch transitions to the RUN
position from any other ignition switch position and no
malfunctions are detected.
"CONTINUOUS MONITORING"-Tests performed by
the DERM on the
SRS every 1 00 milliseconds while
"Ignition
1" voltage is in the normal operating voltage
range at the DERM.
DATA LINK CONNECTOR(DLC)-Formerly "ALDL'', a
connector which allows communication with an
off-board computer, such as a scan
tool.
DATUM LINE-A base line parallel to the plane of the
underbody or frame from which all vertical
measurements originate.
DEPLOY-To inflate the air bag.
DEPLOYMENT
LOOPS - The circuits which supply
current to the inflator modules to deploy the air bag.
DERM -Diagnostic
energy reserve module which
provides reserve energy to the deployment loops and
performs diagnostic monitoring of
all SRS components.
DIAGNOSTIC TROUBLE CODE(DTC) -Formerly
"Code,"a numerical designator used by the DERM to
indicate specific
SRS malfunctions.
DRIVER CURRENT SOURCE-An output of the DERM
which injects current into the driver inflator module circuit
during the "Initiator Assembly Resistance
Test."
DRIVER INFLATOR
MODULE-An assembly located in
the steering wheel hub consisting of an inflatable air bag,
an inflator and an initiator.
DUAL
POLE ARMING SENSOR-A sensor on the high
side(power side) of the deployment loops that is
calibrated to supply voltage to the inflator modules when
the vehicle velocity changes are severe enough to
warrant arming of the air bags in preparation for
deployment.
EEPROM -Electrically Erasable Programmable Read ~
Only Memory. Memory which retains its contents when
power
is removed from the DERM.
FORWARD LH DISCRIMINATING SENSOR-A sensor
on the low side(ground side) of the deployment loops
which is calibrated to ground the inflator modules when
the vehicle velocity changes are severe enough to
warrant deployment of the air bags.
FORWARD RH DISCRIMINATING SENSOR-A sensor
on the low side(ground side) of the deployment loops
which
is calibrated to ground the inflator modules when
the vehicle velocity changes are severe enough

-A battery voltage(B+)circuit which is only
powered with the ignition switch in the RUN,BULB
TEST,or START positions.
INITIATOR-The electrical component inside the inflator
module which, when sufficient current flows, sets off the
chemical reaction that inflates the air bag.
"INITIATOR ASSEMBLY RESISTANCE TEST"-Tests
performed once each ignition cycle when no
malfunctions are detected during "Turn-ON" or
"Continuous Monitoring." This test checks for the correct
DERM configuration for the vehicle, shorts to
"Ignition 1"
in the deployment loops, high resistance or opens in the
"Driver
Side High," "Driver Side Low," "Passenger Side
High"
and "Passenger Side Low" circuits and measures
the resistance of the inflator assembly consisting of: 1)

ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
WARNING: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW
THE PROCEDURES LISTED BELOW TO
TEMPORARILY DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR
BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE
UNNEEDED SRS
REPAIRS.
The DERM in Driver-Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 2
minutes after the ignition switch is turned
"OFF," the
battery is disconnected, or the fuse powering the DERM
is removed.
Many of the service procedures require removal of the
"AIR BAG" fuse, and disconnection of the inflator
modules from the deployment loop to avoid an accidental
deployment.
If the inflator module is disconnected from
the deployment loop as noted in the "Disabling the
SRS"
procedure that follows, service can begin immediately
without waiting for the 2-minute time period to expire.
DISABLING THE SRS
REMOVAL
Turn the ignition switch to "OFF"
1. Remove SRS fuse C-21, C-22, C-23 and C-24 from
left dash side lower fuse block.
2. Disconnect yellow 3-way connector at the base of
steering column.
3. Remove 1/P compartment door assembly, Refer to
"Passenger inflator module replacement" in section
9J-132.
4. Disconnect yellow 4-way connector behind the 1/P
compartment door assembly.
IMPORTANT
• With the "AIR BAG" fuse removed and ignition switch
"ON," if Fuse 21 left. the "AIR BAG" warning lamp will
be "ON." This is normal operation and does not
indicate an
SRS malfunction.
ENABLING THE SRS
INSTALLATION
Turn ignition switch to "LOCK" and remove key.
1. Connect yellow 4-way connector for passenger
inflator module.
2. 1/P compartment door assembly, Refer to
"Passenger inflator module replacemenf' in section
9J-3.
3. Connect yellow 2-way connector at the base of the
steering column.
4. Install "AIR BAG" fuse C-21, C-22, C-23 and C-24 to
left dash side lower fuse block.
Turn ignition switch to
"RUN" and verify that the "AIR
BAG"
warning lamp flashes seven times and then turns
"OFP' If it does not operate as described, perform the
"SRS Diagnostic System Check" in section 9J-2.
HANDLING/INSTALLATION/DIAGNOSIS
1. Inflator modules should not be subjected to
temperatures above
65°C{150°F).
2. Discriminating sensors, inflator modules, arming
sensors, or DERMs should not be used if they have
been dropped from a height
of 91.4 centimeters
{3feet).
3. When a discriminating sensor or arming sensor is
replaced, it must be oriented with the arrow on the
sensor pointing toward the front of the vehicle.
It is
very important for the discriminating sensors and
arming sensor to be located flat on the mounting
surface, parallel to the vehicle datum line.
It is
important that the sensor mounting surface is free of
any dirt or other foreign material.
4. Do not apply power to the SRS unless all
components are connected or a diagnostic chart
requests it, as this
will set a diagnostic trouble code.
5. The "SRS Diagnostic System Check" must be the
starting point of any
SRS diagnostics. The "SRS
Diagnostic System Check" will verify proper "AIR
BAG"
warning lamp operation and will lead you to the
correct chart to diagnose any
SRS malfunctions.
Bypassing these procedures may result
in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.

INFLATOR MODULE HANDLING/SHIPPING/SCRAPPI G
LIVE (UNDEPLOYED) INFLATOR MODULE ~
Special care is necessary when handling and storing a
live (undeployed) inflator module. The rapid gas
generation produced during deployment of the air bag
could cause the inflator module, or an object in front of
the inflator module,
to be thrown through the air in the
unlikely event of an accidental deployment.
WARNING: WHEN CARRYING A LIVE INFLATOR
MODULE, MAKE SURE THE BAG OPENING IS
POINTED
AWAY FROM YOU. IN CASE OF AN
ACCIDENTAL DEPLOYMENT, THE BAG WILL THEN
DEPLOY WITH MINIMAL CHANCE OF INJURY.
NEVER CARRY THE INFLATOR MODULE BY THE
WIRES OR CONNECTOR ON THE UNDERSIDE OF
THE MODULE.WHEN PLACING A LIVE INFLATOR
MODULE ON A BENCH OR OTHER SURFACE,
ALWAYS FACE THE BAG AND TRIM COVER UP,
AWAY FROM THE SURFACE. THIS IS NECESSARY
SO
THAT A FREE SPACE IS PROVIDED TO ALLOW
THE AIR BAG TO EXPAND IN THE UNLIKELY EVENT
OF ACCIDENTAL DEPLOYMENT. NEVER REST A
STEERING COLUMN ASSEMBLY ON THE
STEERING WHEEL WITH THE INFLATOR MODULE
FACE
DOWN AND COLUMN VERTICAL.
OTHERWISE, PERSONAL INJURY MAY RESULT.
INFLATOR MODULE SHIPPING PROCEDURES
FOR
LIVE (UNDEPLOYED) INFLATOR
MODULES
Service personnel should refer to the latest Service
Bulletins for proper SRS inflator module shipping
procedures.
DEPLOYED INFLATOR MODULE
After the inflator module has been deployed, the surface
of the air bag may contain a powdery residue. This
powder consists primarily of cornstarch (used to
lubricate the bag as it inflates) and byproducts of the
chemical reaction. Sodium hydroxide dust( similar
to lye
soap)
is produced as a byproduct of the deployment
reaction. The sodium hydroxide then quickly reacts with
atmospheric moisture and is converted to sodium
carbonate and sodium bicarbonate (baking soda).
Therefore, it
is unlikely that sodium hydroxide will be
present after deployment. As with any procedures, you
should wear gloves and safety glasses.

INFLATOR
PROCEDURE
MODULE

SCRAPPING
'-""' During the course of a vehicle's useful life, certain
situations may arise which
will necessitate the disposal
of a live (undeployed) inflator module. This information
covers proper procedures for disposing of a
live inflator
module.
Before a live inflator module can be disposed of, it must
be
deployed. Live inflator modules must not be disposed
of through
normal refuse channels.
WARNING: FAILURE TO FOLLOW PROPER
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
INFLATOR MODULE DISPOSAL PROCEDURES
CAN RESULT IN AIR BAG DEPLOYMENT WHICH
MAY CAUSE PERSONAL INJURY. UNDEPLOYED
INFLATOR MODULES MUST NOT
BE DISPOSED OF

NORMAL REFUSE CHANNELS. THE
UNDEPLOYED INFLATOR MODULE CONTAINS
SUBSTANCES
THAT CAN CAUSE SEVERE ILLNESS
OR
PERSONAL INJURY IF THE SEALED
CONTAINER IS DAMAGED DURING DISPOSAL.
DISPOSAL IN
ANY MANNER INCONSISTENT WITH
PROPER PROCEDURES MAY BE A VIOLATION OF
FEDERAL, STATE, AND/OR LOCAL LAW.
In situations which require deployment of a live inflator
module, deployment
may be accomplished inside or
outside the
vehicle. The method employed depends
upon the
final disposition of the particular vehicle, as
noted in
"Deployment Outside Vehicle" and "Deployment
Inside Vehicle"
in this section.
Supplemental Restraint System 9J-15

9J-16 Supplemental Restraint ~
DEPLOYMENT OUTSIDE VEHICLE (DRIVER
INFLATOR
MODULE)
Deployment outside the vehicle is proper when the
vehicle is to be returned to service. This includes, for
example, situations in which the vehicle will be returned
to
useful service after a functionally or cosmetically
deficient
inflator module is replaced. Deployment and
disposal of a malfunctioning inflator module is, of course,
subject to any required retention period.
For deployment of a
live (undeployed) inflator module
outside the vehicle, the deployment procedure must be
followed exactly. Always wear safety glasses during this
deployment procedure
until a deployed inflator module is
scrapped
or until an undeployed inflator module is
shipped. Before performing the procedures, you
should
be familiar with servicing the SRS and with proper
handling of the inflator module. Procedures should be
read fully before they are performed.
The following procedure requires use of J-41434
SRS
deployment harness with appropriate pigtail adapter. Do
not attempt procedure without J-41434 adapter.

15.
Separate the two banana plugs on the SRS
deployment harness.
NOTE: When the air bag deploys, the driver inflator
module may jump about
30 em (one foot) vertically. This
is a normal reaction of the driver inflator module to the
force of the rapid gas expansion inside the air bag.
NOTE: When the air bag deploys, the rapid gas
expansion will create a loud noise. Notify all people
in the
immediate area that you intend to deploy the driver
inflator module.
16. Connect the
