Post-installation inspection
After deployment of an air bag, check the passenger’s air bag cut off switch and replace a
new one if there is an abnormality.
REMOVAL SERVICE POINT
<<A>> PASSENGER’S (FRONT) AIR BAG MOD-
ULE CONNECTOR DISCONNECTION
DANGER
Remove the passenger's (front) air bag mod-
ule first to prevent the air bag from deploying
unintentionally, because the passenger's air
bag cut off switch does not have a connector
short circuiting mechanism.
INSTALLATION SERVICE POINTS
>>A<< PRE-INSTALLATION INSPECTION
Check the passenger’s air bag cut off switch for
dents, breakage and bending and measure the
resistance between the terminals, even when install-
ing a new passenger’s air bag cut off switch.

CAUTION
Do not insert a test probe into the terminal from
its front side directly as the connector contact
pressure may be weakened.
4. Make a short-circuit in connector terminals 1 and
2, and measure the resistance between
connectors.
NOTE: The harness, which is of less resistance
(0.1
Ω
or less), should be used to earth the termi-
nals 1 and 2.

Before disposing of an air bag or a vehicle equipped
with an air bag, follow the procedures below to
deploy the air bag.

WARNING
•
If the vehicle is to be scrapped or other-
wise disposed of, deploy the air bags and
operate the seat belt pre-tensioner inside
the vehicle. If the vehicle will continue to
be used and only the air bag modules and
seat belt pre-tensioner are to be disposed
of, deploy the air bags and operate the
seat belt pre-tensioner outside the vehi-
cle.
•
Since a large amount of smoke is pro-
duced when the air bag is deployed and
the seat belt pre-tensioner is operated,
avoid residential areas whenever possi-
ble.
•
Since there is loud noise when the air
bags are deployed and when the seat belt
pre-tensioner are operated, avoid residen-
tial areas whenever possible. If anyone is
nearby, give warning of the impending
noise.
•
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) <DRIVER'S AIR BAG
MODULE>
1. Move the vehicle to an isolated spot.
DANGER
Wait at least 60 seconds after disconnecting
the battery cable before doing any further
work (Refer to
2. Disconnect the negative and positive battery
cables from the battery terminals, and then
remove the battery from the vehicle.
3. Remove the column cover lower (Refer to
GROUP 37, Steering shaft ).

4. Remove the connection between the C-305 clock
spring connector (4-pin) and the harness side
connector (4-pin black).
NOTE: Once disconnected from the instrument
panel wiring harness, both electrodes of the clock
spring connector short automatically. This pre-
vents the driver's air bag from accidental deploy-
ment caused by static, etc.

5. Obtain two suitable wires, which are 6 meters or
longer, as deployment wires. Then connect the
wires at one end to short.
6. Touch the vehicle's body with bare hands to

while the C-305 clock spring connector is
disconnected.
NOTE: The disconnection location should be suf-
ficiently away from the C-305 harness side con-
nector with consideration to the expansion
harness connection location upon disconnections.
8. Connect the deployment wires on the two
instrument panel wiring harnesses disconnected,
cover the connection areas with insulator tape
and then pull out the deployment wires outside the
vehicle.
9. Connect the C-305 harness side connector
connected with an expansion harness to the C-
305 clock spring connector.
