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.
:29-39Nzm (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
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.
