Precautions for SRS ªAIR BAGº and ªSEAT
BELT PRE-TENSIONERº Service
+Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
+Before servicing the SRS, turn ignition switch ªOFFº, disconnect both battery cables and wait 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 ª
Sº 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 driver and passenger air bag modules with the pad side
facing upward and front side air bag modules (built-in type) with the stud bolt side facing down.
+Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
+After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Removal Ð Driver Air Bag Module and Spiral
Cable
CAUTION:
+Before servicing SRS, turn the ignition switch OFF, dis-
connect both battery cables and wait at least 3 minutes.
+Always work from the side of air bag module.
1. Remove lower lid from steering wheel, and disconnect air
bag module connector.
2. Remove side lid, ASCD steering switch and audio steering
switch. Using the TAMPER RESISTANT TORX (Size T30),
remove left and right special bolts. Air bag module can then
be removed.
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.
+Do not insert any foreign objects (screwdriver, etc.) into
air bag module connector.

3. 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 num-
ber of turns.
The spiral cable can be turned up to about 2.5 turns from the
neutral position to both the right and left.
4. Connect spiral cable connector and tighten with screws.
Install steering column cover.
5. Install steering wheel, setting spiral cable pin guide, and pull
spiral cable through.
6. Connect horn connector and engage spiral cable with pawls
in steering wheel. Move air bag module connector away from
steering wheel lower lid opening.
7. Tighten nut.
:29-39Nzm (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
8. Install dynamic damper.
9. Position air bag module and tighten with new special bolts.
+Always service the air bag module from the side.
10. Connect air bag module connector.
11. Install steering switches and lids.
12. Perform self-diagnosis to ensure entire SRS operates prop-
erly. (Use CONSULT-II or warning lamp check.)
Before performing self-diagnosis, connect both battery
cables.
13. 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 posi-
tion.
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 CON-
SULT-II or warning lamp). If a malfunction is detected,
replace the spiral cable with a new one.
14. Perform self-diagnosis again to check that no malfunction is
detected.
