INSTALLATION SERVICE POINTS
APRE-INSTALLATION INSPECTION
1. When installing the new air bag modules and clock spring,
refer to “INSPECTION”.
Caution
Dispose of air bag modules only according to the
specified procedure. (Refer to P.52B-32.)
2. Connect the battery (–) terminal.
3. Connect the MUT-II to the diagnosis connector.
Caution
Make certain that the ignition switch is LOCK (OFF)
when the MUT-II is connected or disconnected.
4. Turn the ignition key to the “ON” position.
5. Conduct self-diagnosis using the MUT-II to ensure entire
SRS operates properly, except open circuit of air bag
modules.
6. Turn the ignition key to the LOCK (OFF) position,
disconnect the negative battery cable and tape the
terminal.
Caution
Wait at least 60 seconds after disconnecting the
battery cable before doing any further work.
(Refer to P.52B-3.)

SRS – Air Bag Modules and Clock Spring52B-29
BCLOCK 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 Mark Alignment
Turn the clock spring clockwise fully, and then turn back it
approx. 3 4/5 turns counterclockwise to align the mating marks.
Caution
If the clock spring’s mating marks are not properly aligned,
the steering wheel may not be completely rotational during
a turn, or the flat cable within the clock spring may be
severed, obstructing normal operation of the SRS and
possibly leading to serious injury to the vehicle’s driver.
CSTEERING WHEEL INSTALLATION
1. Before installation the steering wheel, be sure to first
turn the vehicle’s front wheels to the straight-ahead
position and align the mating marks of the clock spring.
Caution
Be sure when installing the steering wheel, that the
harness of the clock spring does not become caught
or tangled.
2. After clamping, turn the steering wheel all the way in
both directions to confirm that steering is normal.
DPOST-INSTALLATION INSPECTION
1. Turn the steering wheel lightly to the left and right to
check if it can be operated properly without any
abnormality.
2. Reconnect the negative battery terminal.
3. Turn the ignition key to the “ON” position.
4. Does the “SRS” warning lamp illuminate for about 7
seconds, and then remain extinguished for at least 5
seconds after turning OFF?
5. If yes, SRS system is functioning properly.
If no, consult page 52B-6.

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.

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.
