Inspection
If any of the following abnormalities is found, replace on
an assembly basis;
No smooth move of upper/lower anchors in the
circumferential direction.
Damaged and/or deformed through ring.
Damaged and/or deformed tongue.
Damaged and/or frayed of webbing.

wound out and rewound.
Retractor abnormality.
Inspection of retractor
1. ELR (Emergency Locking Retractor) lock inclining
angle check.
When the retractor is moved gently from its installing
position, make sure it is not locked within 15° in any
directions, and it remains locked at 45° or larger.

drawn quickly, make sure it is locked.
3. ALR (Automatic Locking Retractor)/ELR check
(Except for driver’s seat).
When rewound after winding out the seat belt, make
sure the seat belt cannot be taken out. After
rewinding, make sure it has returned to its normal
operation.
CAUTION: Do not disassemble the retractor.
Installation
To install, follow the removal steps in the reverse order,
noting the following point.
1. Be sure to install the lower side anchor plate straight
horizontally, with mounting hole of the plate at the
center.

SDM (Sensing and Diagnostic Module)
WARNING: DURING SERVICE PROCEDURES, BE
VERY CAREFUL WHEN HANDLING A SENSING AND
DIAGNOSTIC MODULE (SDM). NEVER STRIKE OR
JAR THE SDM. NEVER POWER UP THE SRS WHEN
THE SDM IS NOT RIGIDLY ATTACHED TO THE
VEHICLE. ALL SDM AND MOUNTING BRACKETFASTENERS MUST BE CAREFULLY TORQUED AND
THE ARROW MUST BE POINTED TOWARD THE
FRONT OF THE VEHICLE TO ENSURE PROPER
OPERATION OF THE SRS. THE SDM COULD BE
ACTIVATED WHEN POWERED WHILE NOT RIGIDLY
ATTACHED TO THE VEHICLE WHICH COULD CAUSE
DEPLOYMENT AND RESULT IN PERSONAL INJURY.
The Sensing and Diagnostic Module (SDM) is designed
to perform the following functions in the SRS:

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 SYSTEM 9J–10
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.

Sensing And Diagnostic Module (SDM)
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.
