10-2 RESTRAINT SYSTEM
General Description
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, and 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 PRETENSIONER (IF EQUIPPED)
The seat belt with ELR and a pretensioner has a pretensioner mechanism which operates in linkage with the air
bag in addition to the above described ELR. The pretensioner takes up the sag of the seat belt in occurrence of
a front collision with an impact larger than a certain set value, thereby enhancing restraint performance.
DRIVER AND FRONT PASSENGER SIDE AIR BAGS
The driver and front passenger side air bags are components of the air bag system. In occurrence of a front col-
lision with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supple-
ment protection offered by the driver and front passenger seat belts.
•the driver air bag (inflator) module is deployed from the center of the steering column
•the passenger air bag (inflator) module from the top of the instrument panel in front of the front passenger
seat
For more information, refer to Section 10B “Air Bag System”.

AIR BAG SYSTEM 10B-3
General Description
With the air bag system which includes air bags for both the
driver’s and passenger’s sides as well as the seat belt pretension-
ers (if equipped), the sag of the seat belt is taken up (for seat belt
with pretensioner), the driver air bag (inflator) module is deployed
from the center of the steering column and the passenger air bag
(inflator) module from the top of the instrument panel in front of
the front passenger seat in occurrence of a front collision with an
impact larger than a certain set value to supplement protection
offered by the driver and front passenger seat belts.
The air bag system is designed to activate only in severe frontal
collisions. It is not designed to activate in rear impacts, side
impacts, rollovers, or minor frontal collisions, since it would offer
no protection in those types of accidents.

2. Passenger side air bag
3. Seat belt pretensioner (if equipped)

Special tool
(B) : 09932-75010 (Air Bag Driver/Passenger Load Tool)
This tool is used only when called for in this section. It is used as
a diagnostic aid and safety device to prevent inadvertent air bag
(inflator) module deployment.
The load tool has three connectors attached to its case which are
electrically functional and serve as resistive load substitutions.
No more than two connectors are used at any time.
One of connectors (“STEERING WHEEL”) is used to substitute
the load of followings.
•Driver air bag (inflator) module when it is connected at the
top of the column to the contact coil assembly.
•Passenger air bag (inflator) module when it is connected to
the air bag harness connector for passenger air bag (inflator)
module.
•Each of driver and passenger seat belt pretensioners when it
is connected to air bag harness connector for driver and pas-
senger seat belt pretensioner (if equipped).
Another connector (“BASE OF COLUMN”) is used to substitute
the load of the driver air bag (inflator) module and the contact coil
assembly when it is connected at the base of the column to the air
bag wire harness.
The third connector (“PASSENGER INFLATOR”) is not used.
By substituting the resistance of the load tool when called for, a
determination can be made as to whether an inflator circuit com-
ponent is causing system malfunction and which component is
causing the malfunction.
The load tool should be used only when specifically called for in
the diagnostic procedures.
1. Connector for contact coil and driver air bag (inflator) module
(Located near the base of the steering column)
2. Connector for driver, passenger air bag (inflator) module and driver and
passenger seat belt pretensioners
3. Not used
