Scan Tool DataS7RS0B7224007
As the data values given in the following are standard values estimated on the basis of values obtained from the
normally operation vehicles by using a scan tool, use them as reference values. Even when the vehicles are in good
condition, there may be cases where the checked values do not fall within each specifies data range. Therefore,
judgement as abnormal should not be ma de by checking with these data alone.

Seat Belt with ELR
The seat belt with emergency locking retractor (ELR) is
designed so that it locks immediately (to prevent the
webbing from being pulled out of the retractor any
further) when any of the following items is detected as
exceeding each set value;
• Speed at which the webbing is pulled out of the retractor.
• Acceleration or deceleration of the vehicle speed.
• Inclination.
Seat Belt with A-ELR
The automatic and emergency locking retractor (A-ELR)
works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an
Automatic Locking Retractor (ALR ) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out
from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further,
unless it is wound all the way back into the retractor,
which releases the lock and allows the webbing to be
pulled out.
Seat Belt with ELR and Pretensioner
The seat belt with ELR and a pretensioner has a
pretensioner mechanism whic h operates in linkage with
the air bag in addition to the described ELR.
The pretensioner is incorporated in retractor assembly
and controlled by SDM as one of air bag system
components. It will be activated at the same time as the
driver and passenger air bag module when an impact at
the front of vehicle exceeds the specified value.
When servicing seat belt (retractor assembly) with
pretensioner, be sure to observe all WARNINGS and
CAUTIONS and “Precautions on Service and Diagnosis
of Air Bag System in Section 8B”. CAUTION!
Do not reuse the seat belt pretensioner
(retractor assembly) that has activated.
Replace it with a new seat belt assembly and
buckle together as a set. For checking
procedure of its activation, refer to “Repair
and Inspection Required after Accident in
Section 8B”.

Seat Belt Remainder
When driver’s seat belt is unfastened (under the
following conditions), seat belt reminder light and
warning buzzer inform that driver’s seat belt is
unfastened. Seat belt reminder light located in
combination meter and warning buzzer located inside
BCM operate as follows:
• Seat belt reminder light comes on when driver’s seat belt is unfastened while igni tion key switch is at ON
position.
• If vehicle speed exceeds 15 km/h with seat belt unfastened, warning buzzer operates for
approximately 95 seconds and seat belt reminder light
flashes synchronously with buzzer. When warning
buzzer stops operating, seat belt reminder light is
turned on.
• If driver’s seat belt state is changed from “fastened” to “unfastened” while vehicle speed is above 15 km/h,
warning buzzer operates for approximately 95
seconds and seat belt reminder light flashes
synchronously with buzzer. When warning buzzer
stops operating, seat belt reminder light is turned on.
Diagnostic Information and Procedures
Repair and Inspection Required after AccidentS7RS0B8104001
After an accident, whether the seat belt pretensioner has been activated or not, be sure to perform checks and repairs
described on “Repair and Inspection Required after Accident in Section 8B”.

Precautions on Handling and Storage of Air Bag
System Components
S7RS0B8200002
SDM
WARNING!
Never power up air bag system when SDM is
not rigidly attached to the vehicle. Otherwise,
personal injury may result.

CAUTION!
After detecting one time of such collision as
to meet deployment conditions, SDM must
not be used. Refer to “Air Bag Diagnostic
System Check” when checking SDM.

• Never attempt disassembly of SDM.
• When storing SDM, select a place where neither high temperature nor high humidity is anticipated and oil,
water and dust are kept off.
• If SDM has been dropped, replace it with a new one.
• If SDM installation part of floor was damaged, repair that part completely before reinstallation.
• All SDM and mounting bracket fasteners must be carefully torqued and the arrow must be pointed
toward the front of the vehicle to ensure proper
operation of the air bag system. Live (Undeployed) Air Bag (Inflator) Modules
Special care is necessary when handling and storing a
live (undeployed) air bag (inflator) modules.
The rapid gas generation produced during deployment
of the air bag could cause the air bag (inflator) module,
or an object in front of the air bag (inflator) module, to be
thrown through the air in the unlikely event of an
accidental deployment.
WARNING!
Never attempt to measure the resistance of
the air bag (inflator) modules (driver,
passenger and side of both sides and curtain
of both sides). It is
very dangerous as the
electric current from the tester may deploy
the air bag.

Repair and Inspection Required after AccidentS7RS0B8204049
CAUTION!
• All air bag system components, including the electrical harness (component
mounting points), must be inspected after
an accident. If any components are
damaged or bent, they must be replaced
even if air bag system activation did not
occur.
• Never use air bag system parts from another vehicle.
• Do not attempt to service the parts below. Service of these parts is by replacement
only.
– Driver / Passenger air bag (inflator) modules
– Driver / Passenger side-air bag (inflator) modules
– Driver / Passenger side curtain-air bag (inflator) modules
– Driver / Passenger seat belt pretensioners
–Forward-sensor
– Driver / Passenger side-sensors
–SDM
– Contact coil and combination switch assembly
– Air bag wire harness in main harness, instrument panel harness and floor
harness.
• Proper operation of the sensors and air bag system requires that any repairs to the
vehicle structure return it to its original
production configuration.

CAUTION!
After detecting one time of such collision as
to meet deployment conditions, the SDM
must not be used.
Refer to “Air Bag Diagnostic System Check”
when checking the SDM.

Accident with Deployment / Activation – Component
Replacement
When driver and passenger air bags are deployed, the
following components must be replaced.
• Driver and passenger air bag (inflator) modules
• Driver and passenger seat belt pretensioners
• SDM after detecting such collision as to meet
deployment conditions
• Forward-sensor
• Instrument panel When side-air bag and side curtain-air bag are deployed,
the following components must be replaced.
• Deployed side-air bag (inflator) module
• Deployed side curtain-air bag (inflator) module
• Side-sensor
•SDM
Accident with or without Deployment / Activation –
Component Inspections
Certain air bag and restraint system components must
be inspected after any crash, whether the air bag system
activated or not. If any faul
ty condition is found in the
following checks, replace faulty part.
Those components are:
• Steering column (1) and shaft joints
– Check for length, damage and bend according to “Checking Steering Column for Accident Damage in
Section 6B”.
• Steering column bracket (2) and capsules – Check for damage and bent.
• Steering wheel and driver air bag (inflator) module – Check for damage or air bag (inflator) module fitness.
– Check trim cover (pad surface) for cracks.
– Check wire harness and connector for damage or tightness.

Special Tools and Equipment
Use of Special ToolsS7RS0B8208001
WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical test
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified. Do not use a non-powered probe
type tester.
Instructions must be followed carefully,
otherwise personal injury may result.

You should be familiar with the tools listed under the
heading “Special Tool”. You should be able to measure
voltage and resistance. You should be familiar with
proper use of a scan tool such as Air Bag Driver /
Passenger Load Tool, Connector Test Adapter Kit and
the Digital Multimeter.
Special tool
(A): 09932–76010 Connector Test Adapter Kit
This must be used whenever a diagnostic procedure
requests checking or probing a terminal.
Using the appropriate adapter in the special tool will
ensure that no damage to the terminal will occur from the
multimeter probe, such as spreading or bending.
