Repairs And Inspections Required
After An Accident
NOTE: If any SRS components are damaged, they must
be replaced. If SRS component mounting points are
damaged, they must be replaced.
Never use SRS parts from another vehicle. This does
not include remanufactured parts purchased from an
a u t h o r i z e d d e a l e r ; t h e y m a y b e u s e d f o r S R S r e p a i r s .
Do not attempt to service the SDM, the SRS coil
assembly, or the air bag assembly. Service of these
items is by replacement only.
Verify the part number of replacement air bag
assembly.CAUTION: Never use the air bag assembly from
another vehicle. Use only the air bag assembly for
Trooper.
CAUTION: Proper operation of the sensors and
supplemental restraint system (SRS) requires that
any repairs to the vehicle structure return it to the
original production configuration. Deployment
requires, at a minimum, replacement of the SDM, air
bag assembly and dimensional inspection of the
steering column. Any visible damage to the SDM
mounting bracket (s) requires replacement, and the
steering column must be dimensionally inspected,
whether deployment occurred or not.

SUPPLEMENTAL RESTRAINT SYSTEM9J–11
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 93
C (200F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet) or more.
3. When a SDM 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 SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM 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 replacement.
Air Bag Assembly Handling /
Shipping / Scrapping
Live (Undeployed) Air Bag Assembly
Special care is necessary when handling and storing a
live (undeployed) air bag assembly. The rapid gas
generation produced during deployment of the air bag
could cause the air bag assembly, or an object in front of
the air bag assembly, to be thrown through the air in the
unlikely event of an accidental deployment.
827RV004
WARNING: WHEN CARRYING A LIVE AIR BAG
ASSEMBLY, 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 AIR BAG ASSEMBLY BY THEWIRES OR CONNECTOR ON THE UNDERSIDE OF
THE MODULE.
Pretensioner Seat Belt Handling /
Shipping / Scrapping.
Live (undeployed) pretensioner seat belt.
Special care is necessary when handling and storing a
live (undeployed) pretensioner seat belt.
The rapid gas generation produced during deployment of
the pretensioner seat belt (could cause the pretensioner
seat belt), or an object around of pretensioner seat belt, to
be thrown through the air in the unlikely event of an
accidental deployment.
WARNING: WHEN CARRYING A LIVE
PRETENSIONER SEAT BELT, MAKE SURE THE
PRETENSIONER SEAT BELT CYLINDER IS POINTED
AWAY FROM YOU. IN CASE OF AN ACCIDENTAL
DEPLOYMENT, THE PRETENSIONER SEAT BELT
WILL THEN DEPLOY WITH MINIMAL CHANCE OF
INJURY. NEVER CARRY THE PRETENSIONER SEAT
BELT BY THE CYLINDER OR WIRES ON THE
UNDERSIDE OF THE MODULE.

Service personnel should refer to the Service Bulletins for
proper SRS composition parts shipping procedures.

SUPPLEMENTAL RESTRAINT SYSTEM 9J–12
Deployed Air Bag Assembly (Driver Side)
“You should wear gloves and glasses. After the air bag
assembly has been deployed, the surface of the air bag
may contain solid particulate. This solid particulate
c o n s i s t s p r i m a r i l y o f b y p r oducts of the chemical reaction,
Potassium Chloride and copper metal dust. Compounds
of Potassium Borate, Strontium Chloride, Copper
Chloride, and Ammonium Chloride may be found in
amounts of about 1% (each) of the total particulate.”
Deployed Pretensioner Seat Belt.
You should wear gloves and safety glasses. After the
pretensioner seat belt has been deployed, the surface of
the pretensioner seat belt cylinder may heating up.
Air Bag Assembly and/or Pretensioner
Seat Belt Scrapping Procedure.
During the cause of vehicle’s useful life, certain situations
may arise which will necessitate the disposal of a live air
bag and/or pretensioner seat belt. (This information
covers proper procedures for disposing of a live air bag
assembly and/or pretensioner seat belt.)
Before a live air bag assembly can be dispose off, it must
be deployed.
A live air bag assembly and/or pretensioner seat belt
must not be disposed of though normal refuse channels.
WARNING: FAILURE TO FOLLOW PROPER
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR
BAG ASSEMBLY DISPOSAL PROCEDURES CAN
RESULT IN AIR BAG DEPLOYMENT WHICH MAY
CAUSE PERSONAL INJURY. AN UNDPLOYED AIR
BAG ASSEMBLY MUST NOT BE DISPOSED OF
THROUGH NORMAL REFUSE CHANNELS. THE
UNDEPLOYED AIR BAG ASSEMBLY 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 LOCAL
LAW.
In situations which require deployment of a live air bag
assembly, 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.
Cautions About Air Bag Deployment And
Disposal
Failure to follow proper procedures could result in
erroneous air bag deployment which may cause personal
injury be sure to follow proper procedures.
1. Turn off (Lock) the ignition switch and disconnect the
minus terminal of the battery, then start the work 15 or
more sec later. (Air bag is designed to work by the
back-up power source even if the battery power
source is cut off at vehicle collision).
2. Be sure not to disassemble the air bag.
3. Do not give an impact to the air bag and bring the air
bag close to magnet. (The air bag could deploy
unexpectedly).4. Place the air bag with its trim cover up.
5. Do not let the air bag deploy directly on the floor. (The
air bag may be blown off 2
3 m (6.5 or 10 feet)).
6. Be sure to install the air bag firmly to a deployment
tool (fixing tool).
7. Set a battery 10 m (33 feet) or more away from the air
bag.
8. Before disconnecting air bag harness, ground the
worker by touching the vehicle outer panel with bare
hand.
9. When connecting or disconnecting the harness, do
not work just in front of the air bag.
10. As deployment gives rise to big sound, warn the
people around against it. Further, try to reduce the
sound by covering the steering wheel or tires, and
shut the vehicle windows in case of deployment
inside the vehicle.
11. As deployment generates smoke, select a well
ventilated place. (In case of deployment indoors,
avoid deployment just under a fire alarm, smoke
sensor, and fluorescent lamps).
12. Be careful not to inhale the smoke after deployment.
13. If part of the vehicle glass is damaged, cover the
vehicle with a car cover to prevent the glass from
braking at the time of deployment.
14. Do not touch the air bag immediately after
deployment, since it remains hot for 30 minutes.
15. Do not water the air bag immediately after
deployment.
16. Wear safety glasses and gloves throughout the work
and wash the glasses and gloves after the work.
17. Do not reuse the removed air bag for another vehicle.
(Deployment characteristic is different with vehicle
types).
Deployment Outside Vehicle (Driver Air
Bag Assembly)
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
air bag assembly is replaced. Deployment and disposal
of a malfunctioning air bag assembly is, of course, subject
to any required retention period.
For deployment of a live (undeployed) air bag assembly
outside the vehicle, the deployment procedure must be
followed exactly. Always wear safety glasses during this
deployment procedure until a deployed air bag assembly
is scrapped or until an undeployed air bag assembly is
shipped. Before performing the procedures you should
be familiar with servicing the SRS and with proper
handling of the air bag assembly. Procedures should be
read fully before they are performed.
The following procedure requires use of 5–8840–2468–0
SRS deployment harness with appropriate pigtail
adapter. Do not attempt procedure without
5–8840–2468–0 adapter.
WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED MAY RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT

SUPPLEMENTAL RESTRAINT SYSTEM9J–33

Service Precautions
WARNING: DURING SERVICE PROCEDURES, BE
VERY CAREFUL WHEN HANDLING SDM. NEVER
STRIKE OR JAR SDM. UNDER SOME
CIRCUMSTANCES, IT COULD CAUSE
DEPLOYMENT AND RESULT IN PERSONAL INJURY
OR IMPROPER OPERATION OF THE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) . SDM
MOUNTING BRACKET BOLTS MUST BE
CAREFULLY TORQUED TO ASSURE PROPER
OPERATION. NEVER POWER UP THE SRS WHEN
SDM IS NOT RIGIDLY ATTACHED TO THE VEHICLE.
THE SDM COULD BE ACTIVATED WHEN POWERED
WHILE NOT RIGIDLY ATTACHED TO THE VEHICLE
WHICH COULD CAUSE DEPLOYMENT AND RESULT
IN PERSONAL INJURY.
WARNING: PROPER OPERATION OF THE SENSING
AND DIAGNOSTIC MODULE (SDM) REQUIRES THE
SDM TO BE RIGIDLY ATTACHED TO THE VEHICLE
STRUCTURE AND THAT THE ARROW ON THE
SENSOR BE POINTING TOWARD THE FRONT OF
THE VEHICLE.
SDM is specifically calibrated and is keyed to the SDM
location SRS wiring harness. Caution should be used to
ensure proper location of the SDM. The keying of the
SDM to its location and wiring harness connectors should
never be modified in the field.
Removal
1. Disable the SRS (Refer to “Disabling the SRS” in this
section).
2. Remove the transmission knob (for M/T) and transfer
lever knob.
3. Remove the front console assembly and disconnect
