GENERAL – Precautions Before Service00-15
PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B – Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Always use the designated special tools and test equipment.
(3) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the battery cable is disconnected.
(4) Never attempt to disassemble or repair the SRS components. (SRS air bag control unit, air bag
module and clock spring.) If faulty, replace it.
(5) Warnings labels must be needed when servicing and handling SRS components. Warning labels
are located in the following locations.
Sun visor
Glove box
SRS air bag control unit
Steering wheel
Steering gear and linkage
Air bag module
Clock spring
(6) Store components removed from the SRS in a clean and dry place.
The air bag module should be stored on a flat surface and placed so that the pad surface is
facing upwards.
(7) Be sure to deploy the air bag before disposing of air bag module or disposing of a vehicle equipped
with an air bag. (Refer to GROUP 52B – Air Bag Module Disposal Procedures.)
(8) Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure
that the system functions properly.
2. Observe the following when carrying out operations on place where SRS components are installed,
including operations not directly related to the SRS air bag.
(1) When removing or installing parts do not allow any impact or shock to the SRS components.
(2) SRS components should not be subjected to heat over 93C, so remove the SRS components
before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.
SRS – Air Bag Module Disposal Procedures52B-33
3. Peform the following procedure to deploy each air bag
module.
(1) Remove the steering column cover lower.
(2) Remove the connection between the clock spring
2-pin connector (red) and the body wiring harness
connector.
NOTE
If the clock spring connector is disconnected from
the body wiring harness, both electrodes of the clock
spring connector will be automatically shorted to
prevent unintended deployment of the air bag due
to static electricity, etc.
(3) Connect two wires, each six meters or longer, to the
two leads of SRS air bag adapter harness A and
cover the connections with insulation tape. The other
ends of the two wires should be connected to each
other (short-circuited), to prevent sudden unexpected
deployment of the air bag.
(4) Connect the clock spring or air bag module (front
passenger’s side) 2-pin connector (red) to SRS air
bag adapter harness A and pass the deployment
wires out of the vehicle.
(5) Shut all the doors with their window glasses closed
and cover the vehicle with a body cover to suppress
explosion noise leaks as much as possible.
Caution
Be sure to wrap the vehicle entirely in a body cover,
otherwise damaged glass panes could break into
fragments, bringing about a very dangerous situation.
(6) At a location as far away from the vehicle as possible,
disconnect the two connected wires from each other,
and connect them to the two terminals of the battery
(which has been removed from the vehicle) to deploy
the air bag.

(1) Remove the glove box. (Refer to P.52B-27.)
(2) Remove the connection between the air bag module
(front passenger’s side) connector (red 2-pin) and
the body wiring harness connector.
(3) Connect two wires, each six meters or longer, to the
two leads of SRS air bag adapter harness A and
cover the connections with insulation tape. The other
ends of the two wires should be connected to each
other (short-circuited), to prevent sudden unexpected
deployment of the air bag.
(4) Connect the clock spring or air bag module (front

and connect them to the two terminals of the battery
(which has been removed from the vehicle) to deploy

(6) At a location as far away from the air bag module
as possible, and from a shielded position, disconnect
the two connected wires from each other, and connect
them to the two terminals of the battery (which has
been removed from the vehicle) to deploy the air
bag.
Caution
1) Before deployment, check carefully to be sure
that no one is nearby.
2) The inflator will be quite hot immediately
following the deployment, so wait at least 30
minutes to allow it to cool before attempting
to handle it. Although not poisonous, do not
inhale gas from air bag deployment. See
Deployed Air Bag Module Disposal
Procedures (P.52B-40) for post-deployment
handling instructions.
3) If the air bag fails to deploy when the
procedures above are followed, do not go near
the module. Contact your local distributor.
(7) After deployment, dispose of the air bag module
according to the Deployed Air Bag Module Disposal
Procedures. (Refer to P.52B-40.)

(5) Place three old tyres, without wheels, on top of the
tyre secured to the air bag module, and secure all
tyres with ropes (4 locations).
NOTE
The front passenger’s side air bag is larger in capacity
than the driver’s side air bag when deployed. For
this reason, it is necessary to tie up all tyres together
with rope.
(6) At a location as far away from the air bag module
as possible, and from a shielded position, disconnect
the two connected wires from each other, and connect
them to the two terminals of the battery (which has
been removed from the vehicle) to deploy the air
bag.
Caution
1) Before deployment, check carefully to be sure
that no one is nearby.
2) The inflator will be quite hot immediately

3) If the air bag fails to deploy when the
procedures above are followed, do not go near
the module. Contact your local distributor.
(7) After deployment, dispose of the air bag module
according to the Deployed Air Bag Module Disposal
Procedures.
DEPLOYED AIR BAG MODULE DISPOSAL
PROCEDURES
After deployment, the air bag module should be disposed
of in the same manner as any other scrap parts, adhering
to local laws and/or legislation that may be in force except
that the following points should be carefully noted during
disposal.
1. The inflator will be quite hot immediately following
deployment, so wait at least 30 minutes to allow it cool
before attempting to handle it.
2. Do not put water or oil on the air bag after deployment.
