INSPECTION

AIR BAG MODULE CHECK

If any improper part is found during the following inspection,
replace the air bag modules with a new one.
Dispose the old one according to the specified procedure.
(Refer to P.52B-32.)

Caution
Never attempt to measure the circuit resistance of the
air bag modules (squib) even if you are using the specified
tester. If the circuit resistance is measured with a tester,
accidental air bags deployment will result in serious
personal injury.

1.

Check pad cover for dents, cracks or deformation.

2.

Check connectors for damage, terminals for deformation,
and harness for binds.

3.

Check air bag inflator case for dents, cracks or
deformation.

4.

Install the air bag module to steering wheel to check
fit or alignment with the wheel.

Caution
If dents, cracks, deformation, or rust are discovered in
the air bag module, replace it with a new one.
Dispose of the old one according to the specified
procedure. (Refer to P.52B-32.)

CLOCK SPRING CHECK

If, as result of following checks, even one abnormal point
is discovered, replace the clock spring with a new one.
1.

Check connectors and protective tube for damage, and
terminals for deformation.

2.

Visually check the case for damage.

3.

Check that there is continuity between terminal (3) of
the clock spring No.1 connector and the No. 2 connector.

4.

Joint the No.3 connector and No.4 connector of the clock
spring to connector No.6 and connector No.4 respectively,
of the SRS check harness.

NOTE
When joining SRS check harness connector No.4 align
its white paint with the hollow portion of the No.4 connector
of the clock spring.

5.

Check for continuity between terminal 22 and terminal
25, and terminal 23 and terminal 24, of SRS Check
Harness connector No. 5 using a digital multi-meter.

Air Bag Module Disposal Procedures

52B-32

AIR BAG MODULE DISPOSAL PROCEDURES

Before disposing of an air bag or a vehicle which
is equipped with it, the procedures below are to
be followed to deploy them.

UNDEPLOYED AIR BAG MODULE DISPOSAL
PROCEDURES

Caution
1.

If the vehicle is to be scrapped or otherwise disposed
of, deploy the air bags inside the vehicle. If the vehicle
will continue to be used and only the air bag modules
are to be disposed of, deploy the air bags outside
the vehicle.

2.

Since a large amount of smoke is produced when
the air bag is deployed, avoid residential areas
whenever possible.

3.

Since there is loud noise when the air bags are
deployed, avoid residential areas whenever possible.
If anyone is nearby, give warning of the impending
noise.

4.

Suitable ear protection should be worn by personnel
performing these procedures or by people in the
immediate area.

DEPLOYMENT INSIDE THE VEHICLE

(when disposing of a vehicle)

1.

Move the vehicle to an isolated spot.

2.

Disconnect the negative (–) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.

Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work.
(Refer to P.52B-3.)

3.

Peform the following procedure to deploy each air bag
module.

<Air bag module (driver’s side)>

(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.
