INSTALLATIONNJRS00171. 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 3.5 revo-
lutions from the right end position. Align the two marks (
)or
make sure that the white indicator is visible in the upper part
of the indicator window, with the cable pointed downwards.
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 up to
about 3.5 turns from the neutral position to both the right
and left.
3. Connect 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/audio connector and engage spiral cable with
pawls in steering wheel. Move driver air bag module connec-
tor away from steering wheel lower lid opening.

10. Install the air bag module, press the center of the horn pad to
make contact (RH/LH) ON.
11. Conduct self-diagnosis to ensure entire SRS operates prop-
erly. (Use CONSULT-II or warning lamp check.)
Before performing self-diagnosis, connect both battery cables.
12. 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.
13. Perform self-diagnosis again to check that no malfunction is
detected.
