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
authorized dealer; they may be used for SRS repairs.

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.

Accident With Deployment – Component
Replacement And Inspections

Certain SRS components must be replaced or inspected
for damage after a frontal crash involving air bag
deployment. Those components are:

Air bag assembly

SDM

CAUTION: Refer to “SDM Replacement Guidelines”
below for important information on SDM
replacement in both deployment and non
deployment crashes.

SRS coil assembly — Inspect wiring and connector
for any signs of scorching, melting, or damage due to
excessive heat. Replace if damaged. Refer to
section “SRS Coil Assembly” in this manual.

Accident With or Without Deployment –
Component Inspection

Certain SRS system components and rotation parts must
be inspected after any crash, whether the air bag
deployed or not. Those components are:

Steering column — Refer to Inspection Required
“After an Accident” in this manual.

Knee bolsters and mounting points — Inspect for any
distortion, bending, cracking, or other damage.

I/P steering column reinforcement plate — Inspect for
any distortion, bending, cracking, or other damage.

I/P braces — Inspect for any distortion, bending,
cracking, or other damage.

Seat belts and mounting points — Refer to “Seat
Belts” in Section “Seat Belt” of this workshop manual.

SDM Replacement Guidelines

SDM replacement policy requires replacement of SDM,
after crash involving air bag deployment when “SRS
Warning Lamp” turn “ON”, “SRS Diagnosis” should be
done according to Section “Restraint Control System.”
If accident without deployment air bag, it is not necessary
replacement of SDM when do not indicate to replace the
SDM by scan tool after SRS system check.

Wiring Damage

If any SRS wire harness is damaged, it should be
replaced. Don’t repair SRS harness. It is replace only.

SRS Connector (Plastic Body And
Terminal Metal Pin) Damage

If any connector or terminal in the SRS wire harness
(except pigtails) is damaged, it should be replaced.

SRS Wire Pigtail Damage

If the wiring pigtail (a wire or wires attached directly to the
device, not by a connector) is damaged, the entire
component (with pigtail) must be replaced. Examples of
“pigtail” components are the driver air bag assembly, the
passenger air bag assembly, and the SRS coil assembly.

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 SDM 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 SDM is
removed.
Many of the service procedures require removal of the
“C–21” 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 C–21, from left dash side lower

fuse block or disconnect battery.

2. Disconnect yellow 2–pin connector at the base of

steering column.

3. Remove glove box assembly, refer to “Passenger Air

Bag Assembly Replacement” in this manual.

4. Disconnect yellow 2–pin connector behind the glove

box assembly.

CAUTION: With the “C–21” 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. Use only the air bag assembly for
Trooper.
Turn ignition switch to “LOCK” and remove key.

1. Connect yellow 2–pin connector passenger air bag

assembly.

2. Install glove box assembly. Refer to “Passenger air

bag assembly replacement” in this manual.

3. Connect yellow 2–pin connector at the base of

steering column.

4. Install “AIR BAG” fuse C–21 to left dash side lower

fuse block or connect battery.

Turn ignition switch to “ON” and verify that the “AIR BAG”
warning lamp turn on 3.5 seconds 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 93

C (200

F).

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 THE

WIRES 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.

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
consists primarily of by products 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
