INSTALLATION
Install in the reverse order of removal.
CAUTION:

The spiral cable may snap by steering operation if the cable
is installed in an improper position.

The neutral position is set as follows.
Turn quietly the spiral cable clockwise to the end position.
Then turn it counterclockwise (about 2 and harf turns) and
stop turning at the point on which the stopper insertion
holes are in the same position.
The service part is installed in the neutral position by the
stopper and can be set without adjusting after the stopper
is removed.

Do not turn the spiral cable rashly and also beyond the limit
number of turns. (These will cause cable snap.)

Adjust the spiral cable locating pin (showed as A inthe fig-
ure) to the steering wheel locating pin hole (showed as C in
the figuer).

Secure the air bag harness with the harness fixing hook.

After the work is completed, make sure no system malfunc-
tion is detected by air bag warning lamp.

In case that malfunction is detected by the air bag warning
lamp, reset by the self-diagnosis function and delete the
memory by CONSULT−IlI.

In case that malfunction is still detected after the above
operation, perform self-diagnosis to repair malfunctions.
