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.

9J-22 Supplemental Restraint System
AIR BAG TO EXPAND IN THE UNLIKELY EVENT OF
ACCEIDENTAL DEPLOYMENT. FAILURE TO
FOLLOW PROCEDURES MAY RESULT IN
PERSONAL INJURY.
26. Temporarily store the inflator module with the bag
facing up, away from the surface upon which it rests.
27.
Call the Technical Assistance group for further
assistance.
DEPLOYMENT INSIDE VEHICLE(VEHICLE
SCRAPPING PROCEDURE)
Deployment inside vehicle is proper when the vehicle is
to be destroyed or
salvaged for component parts. This
includes, but is not limited to, the following situations.
1. The vehicle has completed its useful life.
2. The vehicle has been damaged beyond repair in a
non-deployment type accident.
3. The vehicle has been stripped or damaged beyond
repair
in a theft.
4. The vehicle will be salvaged for component parts to
be
used on a vehicle with a different Vehicle
Identification Number (VIN) as opposed to being
rebuilt as same VIN. Never use SRS components
from another
vehicle. This is done to ensure SRS
system integrity since only new SRS system
components.
WARNING: FAILURE TO FOLLOW PROPER SRS
INFLATOR MODULE DISPOSAL PROCEDURES
CAN RESULT IN AIR BAG DEPLOYMENT WHICH
MAY CAUSE PERSONAL INJURY. UNDEPLOYED
INFLATOR MODULES MUST NOT BE DISPOSED OF
THROUGH NORMAL REFUSE CHANNELS. THE
UNDEPLOYED INFLATOR MODULE CONTAINS
SUBSTANCES THAT CAL 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 LAWS.
1. Turn ignition switch to "LOCK," remove key and put
on safety glasses.
2. Remove all loose objects from front seats.
3. Disconnect driver inflator module, yellow 3-way
connector located at the base of the steering column.
4. Cut the driver inflator module yellow 2-way harness
connector from the
vehicle leaving at least 16 cm(six
inches) of wire at the connector.
5. Strip 13 mm(1/2 inch) of insulation from each wire
lead of the connector.
6. Cut two 900 cm(30 feet) deployment wires from
0.8mm2(18 gauge) or thicker
multi-strand wire. These
wires
will be used to fabricate the driver
deployment harness.
7. Strip 13 mm(1/2 inch) of insulation from both ends of
the wires cut
in the previous step.
8. Short the wires by twisting together one end from
each. Deployment wires
shall remain shorted and
not
be connected to a power source until the air bag
is to be
deployed.
WARNING: FAILURE TO
FOLLOW PROCEDURES
IN
THE ORDER LISTED COULD RESULT IN
PERSONAL INJURY. NEVER CONNECT
DEPLOYMENT WIRES TO ANY POWER SOURCE
BEFORE CONNECTING DEPLOYMENT WIRES TO
THE INFLATOR MODULE LEADS. DEPLOYMENT
WIRES SHALL REMAIN SHORTED AND NOT BE
CONNECTED TO A POWER SOURCE UNTIL THE
AIR BAG IS TO BE DEPLOYED. THE INFLATOR
MODULE WILL IMMEDIATELY DEPLOY THE AIR
BAG WHEN A POWER SOURCE IS CONNECTED TO
IT. WEAR SAFETY GLASSES THROUGHOUT THIS
ENTIRE DEPLOYMENT AND DISPOSAL
PROCEDURE.
9. Twist together one connector wire lead to one
deployment wire. The connection should be
mechanically secure.
10. Bend twisted connection made in the previous step
flat and wrap tightly with electrical tape to insulate ~
and secure.
11. Twist together, bend and tape the remaining
connector wire lead to the remaining deployment
wire.
12. Connect the deployment harness to the driver
inflator module, yellow 2-way connector at the base
of the steering
column. Route deployment harness
out the driver side of the
vehicle.
WARNING:
DEPLOYMENT WIRES SHALL REMAIN
SHORTED
AND NOT BE CONNECTED TO A POWER
SOURCE UNTIL THE AIR BAG IS TO BE DEPLOYED.
THE INFLATOR MODULE WILL IMMEDIATELY
DEPLOY THE AIR BAG WHEN A POWER SOURCE IS
CONNECTED TO IT.
CONNECTING THE DEPLOYMENT WIRES TO THE
POWER
SOURCE SHOULD ALWAYS BE THE FINAL
STEP IN
THE INFLATOR MODULE DEPLOYMENT
PROCEDURE. FAILURE TO FOLLOW
PROCEDURES IN THE ORDER LISTED COULD
RESULT IN PERSONAL INJURY.
13. Disconnect passenger inflator module, yellow 2-way
connector located behind 1/P compartment door
assembly.
14. Cut the passenger inflator module harness
connector from the vehicle leaving at least 16 cm(six
inches) of wire at the connector).

\V CAUTION : When fasteners are removed, always reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use the correct part number fastener for
that application. If the correct part number fastener is not available, a fastener of equal size
