Precautions for SRS ``AIR BAG'' and ``Seat Belt
Pre-tensioner'' Service
+Do not use a circuit tester to check SRS circuits unless instructed to in this Service Manual.
+Before servicing the SRS, turn ignition switch ``OFF'', disconnect both battery cables and wait for at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
+Diagnosis sensor unit must always be installed with their arrow marks ``
S'' pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
+The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
+Handle air bag module carefully. Always place it with the pad side facing upward.
+Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
+Instrument panel assembly should be replaced after air bag in¯ates if damaged.

Maintenance Items
CAUTION:
Do not use a circuit tester to check SRS circuit.
1. Check operation of ``AIR BAG'' warning lamp.
After turning ignition key to ``ON'' position, both warning lamps
illuminate. The ``AIR BAG'' warning lamp will go off after about
7 seconds if no malfunction is detected.
If any of the following warning lamp conditions occur, immedi-
ately check the air bag or seat belt pre-tensioner system. Refer
to RS-30 for details.
+The ``AIR BAG'' warning lamp does not illuminate when the
ignition switch is turned ``ON''.
+The ``AIR BAG'' warning lamp does not go off about 7 seconds
after the ignition switch is turned ``ON''.
+The ``AIR BAG'' warning lamp blinks about 7 seconds after the
ignition switch is turned ``ON''.
2. Visually check SRS components.
(1) Diagnosis sensor unit
+Check diagnosis sensor unit and bracket for dents, cracks or
deformities.
+Check connectors for damage, and terminals for deformities.
(2) Air bag module and steering wheel
+Remove air bag module from steering wheel or instrument
panel. Check harness cover and connectors for damage, ter-
minals for deformities, and harness for binding.
+Install driver air bag module to steering wheel to check ®t or
alignment with the wheel.
+Check steering wheel for excessive free play.
+For dual air bag system, install passenger air bag module to
instrument panel to check ®t or alignment with the instrument
panel.
(3) Spiral cable
+Check spiral cable for dents, cracks, or deformities.
+Check connectors and protective tape for damage.
+Check steering wheel for noise, binding or heavy operation.
(4) Harness related to SRS
+Check connectors for poor connections, damage, and terminals
for deformities.
+Check harnesses for binding, cha®ng or cut.
(5) Seat belt pre-tensioner
+Check harness cover and connectors for damage, terminals for
deformities, and harness for binding.
+Check belts for damage and anchors for loose mounting.
+Check retractor for smooth operation.
+Perform self-diagnosis for seat belt pre-tensioner using
bulb or CONSULT. Refer to ``SRS Operation Check'' for details.

CAUTION:
+Always place air bag module with pad side facing upward.
+Do not attempt to disassemble air bag module.
+The special bolts are coated with bonding agent. Do not
use old bolts after removal; replace with new ones.
+Replace air bag module if it has been dropped or sustained
an impact.
+Do not expose the air bag module to temperatures exceed-
ing 90ÉC (194ÉF).
+Do not allow oil, grease or water to come in contact with
the air bag module.
3. Set steering wheel in the neutral position.
4. Disconnect horn connector and remove nuts.
5. Using steering wheel puller, remove steering wheel. Be careful
not to over-tighten puller bolt on steering wheel.
CAUTION:
Do not tap or bump the steering wheel.
6. Remove steering column cover.
7. Remove four screws securing the spiral cable. Unlock the spi-
ral cable connector. Then disconnect the spiral cable connec-
tor. The spiral cable can then be removed.
CAUTION:
+Do not attempt to disassemble spiral cable.
+Do not apply lubricant to the spiral cable.

Installation Ð Air Bag Module and Spiral Cable
1. Set the front wheels in the straight-ahead position.
2. Make sure that the spiral cable is in the neutral position. The
neutral position is detected by turning left about 2.5 revolutions
from the right end position. Align the two marks (
,
m).
CAUTION:
+The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
+Also, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned to the left
about 2.5 turns from the right end position.
3. Connect and lock spiral cable connector and tighten with
screws. Install steering column cover.
4. Install steering wheel, aligning with spiral cable pin guides, and
pull spiral cable through.
5. Connect horn connector and engage spiral cable with pawls in
steering wheel. Move air bag module connector away from
steering wheel lower lid opening.
6. Tighten nut.

7. Position air bag module and tighten with new special bolts.
8. Connect air bag module connector.
9. Install all lids.
10. Conduct self-diagnosis to ensure entire SRS operates properly.
(Use CONSULT or warning lamp check.)
Before performing self-diagnosis, connect both battery cables.
11. Turn steering wheel to the left end and then to the right end fully
to make sure that spiral cable is set in the neutral position.
If air bag warning lamp blinks or stays ON (at the User mode),
it shows the spiral cable may be snapped due to its improper
position. Perform self-diagnosis again (use CONSULT or warn-
ing lamp). If a malfunction is detected, replace the spiral cable
with a new one.
12. Perform self-diagnosis again to check that no malfunction is
detected.

The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable may
snap by turning the steering wheel beyond the limited number
of turns. (The spiral cable can be turned up to 2.5 turns from
the neutral position to both the right and left.)
