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.
Refer to Refer to SRS-27, "
SRS Operation Check (USER MODE)" .

COLLISION DIAGNOSISPFP:00015
For Frontal CollisionNHS00011
To repair the SRS, perform the following steps.
When SRS (except the front side air bag and side curtain air bag modules) is activated in a collision:
1. Replace the diagnosis sensor unit.
2. Remove the air bag modules (except the front side air bag modules and side curtain air bag modules),
crash zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
3. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
4. Install new air bag modules (except the front side air bag modules and side curtain air bag modules) crash
zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
5. Perform self-diagnosis using CONSULT-IlI or “AIR BAG” warning lamp. Refer to SRS-27, "
SRS Operation
Check (USER MODE)" for details. Ensure entire SRS operates properly.
When SRS is not activated in a collision:
1. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
2. Perform self-diagnosis using CONSULT-IlI or “AIR BAG” warning lamp. Refer to SRS-27, "
SRS Operation
Check (USER MODE)" for details. Ensure entire SRS operates properly.
When only one front air bag module is activated in a collision:
1. Replace the following components:
–Diagnosis sensor unit
–Crash zone sensor
–Activated front air bag and seat belt pre-tensioner.
2. Check the other SRS components using the table below. (Refer to “SRS is NOT activated”.)
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
3. Perform self-diagnosis using CONSULT-IlI or “AIR BAG” warning lamp. Refer to SRS-27, "
SRS Operation
Check (USER MODE)" for details. Ensure entire SRS operates properly.
Only one front air bag may inflate a crash, depending on the crash severity and whether the front occupants
are belted or unbelted. This does not indicate improper performance of the system. Perform self-diagnosis to
make sure the entire SRS operates properly.
