On–Vehicle Service
Service Precaution
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 SRS control unit in Driver–Passenger SRS can
maintain sufficient voltage to cause a deployment for
up to 15 seconds after the ignition switch is turned
“OFF,” the battery is disconnected, or the fuse
powering the SRS control unit is removed.
Many of the service procedures require removal of the
“SRS” fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected
from the deployment loop as noted in the “Disabling
the SRS” procedure that follows, service can begin
immediately without waiting for the 15 second time
period to expire.

Disabling The SRS
Removal
Turn the ignition switch to “LOCK” and remove key.
1. Remove SRS fuse “SRS”, from the side of the
driver side of instrument panel fuse block o
r
disconnect battery.
2. Disconnect yellow connector at the base o
f
steering column.
3. Remove glove box assembly, refer to “Passenge
r
Air Bag Assembly Replacement” in this manual.
4. Disconnect yellow connector behind the glove box
assembly.
CAUTION: With the “SRS” fuse removed and
ignition switch “ON”, the “AIR BAG” warning lamp
will be “ON”. This is normal operation and does
not indicate an SRS malfunction.

Enabling The SRS
Installation
CAUTION: Never use the air bag assembly from
another vehicle and difference model year air bag
assembly.
Use only new air bag assembly proper to the
TFR/S which is being repaired.
Turn ignition switch to “LOCK” and remove key.
1. Connect yellow connector passenger air bag
assembly.
2. Install glove box assembly. Refer to “Passenger ai
r
bag assembly replacement” in this manual.
3. Connect yellow connector at the base of steering
column.
4. Install “AIR BAG” fuse “SRS” to the side of the
driver side of instrument panel fuse block o
r
connect battery.
Turn ignition switch to “ON” and verify that the “AIR
BAG” warning lamp flashes seven times and then
turns “OFF.” If it does not operate as described,
perform the “SRS Diagnostic System Check” in this
manual.

Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 65

C (150
F).
2.
Air bag assembly, and SRS control unit should not
be used if they have been dropped from a height
of 100 centimeters (3.28 feet) or more.
3. When a SRS control unit 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 SRS control unit to be located flat on the
mounting surface, parallel to the vehicle datum
line. It is important that the SRS control unit
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 ma
y
result in extended diagnostic time, incorrect
diagnosis, and incorrect parts replacement.

20.The passenger inflator requires no special
precaution after deployment. 95% of the
particulate emission are potassium ckloride (KLC),
which is commonly sold as an edible salt-
substitutes. even if water is applied. Pos
t
deployment products are relatively pH neutral.
Disposing the inflator by burying it in a landfill will
not produce any hazardous products. As with an
y
dusty environment, safety goggles, dust mask and
gloves should be worn.
WARNING: SAFETY PRECAUTIONS MUST BE
OBSERVED WHEN HANDLING A DEPLOYED AI
R
BAG ASSEMBLY. AFTER DEPLOYMENT, THE
METAL SURFACES OF THE AIR BAG ASSEMBLY
WILL BE HOT. ALLOW THE AIR BAG ASSEMBLY
TO COOL BEFORE HANDLING ANY METAL
PORTION OF IT. DO NOT PLACE THE DEPLOYED
INFLATOR MODULE NEAR ANY FLAMMABLE
OBJECTS. FAILURE TO FOLLOW PROCEDURES
MAY RESULT IN FIRE OR PERSONAL INJURY.
AFTER AN AIR BAG ASSEMBLY HAS BEEN
DEPLOYED, THE METAL CANISTER AND
SURROUNDING AREAS OF THE AIR BAG
ASSEMBLY WILL BE HOT. DO NOT TOUCH THE
METAL AREAS OF THE AIR BAG ASSEMBLY FO
R
ABOUT THIRTY MINUTES AFTER DEPLOYMENT.
IF THE DEPLOYED AIR BAG ASSEMBLY MUST BE
MOVED BEFORE IT IS COOL, WEAR GLOVES AND
HANDLE BY THE AIR BAG ITSELF.
21. Disconnect the pigtail adapter from the air bag
assembly as soon after deployment as possible to
avoid damage to the pigtail adapter or SRS
deployment harness from contacting the hot ai
r
bag assembly canister. The pigtail adapter and
SRS deployment harness are designed to be
reused. They should, however, be inspected fo
r
damage after each deployment and replaced if
necessary.
22. Dispose of the deployed air bag assembly through
normal refuse channels after it has cooled for a
t
least 30 minutes.
23. Wash your hands with mild soap and wate
r
afterward.
NOTE: The remaining steps are to be followed in the
unlikely event that the air bag assembly did not deplo
y
after following the above procedures.
24. Ensure that the SRS deployment harness has
been disconnected from the power source and tha
t
its two banana plugs have been shorted together
by fully seating one banana plug into the other.
25. Disconnect the pigtail adapter from the air bag
assembly.
WARNING: WHEN STORING A LIVE AIR BAG
ASSEMBLY OR WHEN LEAVING A LIVE AIR BAG
ASSEMBLY UNATTENDED ON A BENCH OR
OTHER SURFACE, ALWAYS FACE THE BAG UP
AND 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. FAILURE TO FOLLOW
PROCEDURES MAY RESULT IN PERSONAL
INJURY.
26. Temporarily store the air bag assembly with the
bag facing up, away from the surface upon which it
rests.

The SRS control unit in Driver–Passenger SRS can
maintain sufficient voltage to cause a deployment for
up to 15 seconds after the ignition switch is turned
“OFF,” the battery is disconnected, or the fuse
powering the SRS control unit is removed.
Many of the service procedures require removal of the
“SRS” fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected
from the deployment loop as noted in the “Disabling
the SRS” procedure that follows, service can begin
immediately without waiting for the 15 second time
period to expire.

Disabling The SRS
