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-

DISPOSAL PROCEDURES

M1524001201915

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

AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-290

UNDEPLOYED AIR BAG MODULE DIS-
POSAL

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 

P.52B-5

).

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 

discharge static in you.

7. Cut with a pliers, etc. the instrument panel wiring 

harness shown in the figure of the instructions, 
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.
