INSTALLATION SERVICE POINTS
PRE-INSTALLATION INSPECTION
(1) When installing the new air bag clock spring,
refer to “INSPECTION”
Caution
Dispose of an air bag module only according to the
specified procedure. (Refer to
(2) Connect the battery terminal.
(3) Connect the scan tool to the data link connecto r, then
check diagnostic codes.
Caution
Turn the ignition switch off before disconnecting o r
connecting the scan tool.
(4) Turn the ignition key to the “ON” position.
(5) Conduct diagnostic test mode using the scan too l to, en-
sure entire SRS operates properly, except open circuit
of air bag module (diagnostic trouble code
25).

(6) Turn the ignition key to the “LOCK” position, disconnect
the negative battery cable and tape the terminal.Insulating tape
Caution
Wait at least 60 seconds after disconnecting the ba t-
tery cable before doing any further work.
(Refer to
CLOCK SPRING INSTALLATION
Align the mating marks of the clock spring, and, after turning
the front wheels to the straight-ahead position, install the
clock spring to the column switch.
Mating Marks Alignment
Turn the clock spring clockwise fully, and then tur n back it
approx. 3 turns counterclockwise to align the mating marks.
Caution
If the clock spring’s mating marks are not aligned,
the steering wheel may not be completely
a turn, or the flat cable within the clock spring m ay be
severed, obstructing normal operation of the SRS.
STEERING WHEEL INSTALLATION
(1) Before installing the steering wheel, be sure t o first turn
the vehicle’s front wheels to the straight-ahead po sition
and align the mating marks of the clock spring.
Caution
Be sure when installing the steering wheel, that th e
harness of the clock spring does not become caught
or tangled.
(2) After installing, turn the steering wheel’
‘the way in
both directions to confirm that steering is normal.

POST-INSTALLATION INSPECTION
(1) After installing the clock spring, the steering wheel, the
column covers and the air bag
check
wheel for noise, binds or difficult operation.
(2) Reconnect the negative battery terminal. Turn t he ignition
key to the “ON” position. Does “SRS” warning light
illuminate for about 7 seconds, turn OFF and then r emain
OFF? If yes, SRS system is functioning properly. If no,
consult page
INSPECTION
AIR BAG MODULE CHECK
If any improper part is found during the following inspection,
replace the air bag module with a
Dispose of the old one according to the specified p rocedure.
(Refer to
Caution
Never attempt to measure the circuit resistance of the
air bag module (squib) even if you are using the specified
tester. If the circuit resistance is measured with
accidental air bag deployment will result in seriou s per-
sonal injury.
(1) Check pad cover for dents, cracks or deformation.
(2)Check the air bag module for dents, cracks or defor mation.
(3) Check hooks and connectors for damage, terminal s for
deformation, and harness for binds.
(4) Check air bag inflator case for dents, cracks o r deforma-
tion.

(5) Install the air bag module on the steering whee l to check
alignment with the wheel.
CLOCK SPRING CHECK
If, as result of the following checks, even one abn ormal point
is discovered, replace the clock spring with a new one.
(1) Check connectors and protective tube for. damag e, and
terminals for deformation.
(2) Visually check the case for damage”

SRS Air Bag Module Disposal,. Procedures
AIR BAG MODULE DISPOSAL PROCEDURES 52499120999
Before either disposing of a vehicle equipped with
an air bag, or prior to disposing of the air bag ule, be sure to first follow the procedures describ ed
below to deploy the air bag.
A I R
Caution
1.If the vehicle is to be scrapped, or otherwise disp osed
of, deploy the air bag inside the vehicle. If the v ehicle
will continue to be operated and only the air bag m od-
ule is to be disposed of, deploy the air bag outside
the vehicle.
2. Since a large amount of smoke is produced when the air bag is deployed, select a well-ventilated s ite.
Moreover, never attempt the test near a smoke senso r.
3. Since there is a loud noise when the air bag is
deployed, avoid
areas whenever possible.
If anyone is nearby, give warning of the impending
noise.
4.Suitable ear protection be worn by personnel
performing these procedures or by people in the im-
mediate area.
DEPLOYMENT INSIDE THE VEHICLE
(when disposing of a vehicle)
(1) Open all windows and doors of. the vehicle. Mov e the
vehicle to an isolated spot.
(2)Disconnect the negative and positive battery cables
from the battery terminals, and then remove the bat tery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
tery cables before doing any further work.

(3) Remove the steering column cover lower.
(4) Remove the connection between the clock spring
connector (red) and the body wiring harness connect or.
NOTE
the clock spring connector is disconnected from th e
body wiring harness, both electrodes of the clock s pring
connector will be automatically shorted to prevent unin-
tended deployment of the air bag due to static elec tricity,
etc.

(6)Disconnect the (red) connector of the air bag module
(front passenger’s side) from the body wiring harne
ss
connector.
NOTE
If the air bag module (front passenger’s side) connector
is disconnected from the body wiring harness, both elec-
trodes of the air bag module (front passenger’s side)
connector will be automatically shorted to prevent unin-
tended deployment of the air bag due to static elec tricity,
etc.
Connect two wires,each six meters (20 feet) long or
more, to the two leads of SRS AIR BAG ADAPTER HAR-
NESS A and cover the connections with insulation ta pe.
The other ends of the two wires should be connected
to each other (short-circuited), to prevent sudden unex-
pected deployment of the air bag.
(8) Connect the clock spring
connector (red) to SRS
air bag adapter harness A and pass the deployment w ires
out of the vehicle.
(9) Connect the SRS air bag adapter harness A to th e
connector (red) of the air bag module (front passengers
side) and pass the deployment wire out of the vehic le.
a location as far away from the vehicle as
disconnect the two connected wires from each other, and
connect them to the two terminals of the battery (r emoved
from the vehicle) to deploy the air bag.
Caution
1.Before deploying the air bag in this manner,
check to sure that there is no one near
the vehicle. Wear safety goggles,
ear
protection.
