4. While pressing tabs, pull lighting and turn signal switch toward
driver door and disconnect from base.
5. Remove the screws, release the clip, and remove the spiral cable.
CAUTION:
Do not disassemble spiral cable.
Do not apply lubricant to the spiral cable.
6. Remove the spiral cable connectors. CAUTION:
With the steering linkage disconnected, the spiral cable may snap by turning the steering wheel
beyond the limited number of turns. The spiral cable can be turned counterclockwise about 2.5
turns from the neutral position.
INSTALLATION
Installation is in the reverse order of removal.
Align spiral cable correctly when installing steering wheel. Make
sure that the spiral cable is in the neutral position. The neutral
position is detected by turning left 2.6 revolutions from the right
end position and ending with the knob at the top.
If equipped with VDC, refer to BRC-62, "Adjustment of Steering
Angle Sensor Neutral Position" for steering angle sensor adjust-
ment.
After the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer to SRS-20, "
SRS Operation
Check" .
CAUTION:
The spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
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 counterclockwise
about 2.5 turns from the right end position.

FRONT PASSENGER AIR BAG MODULE
Revision: November 20092006 QX56
FRONT PASSENGER AIR BAG MODULEPFP:K8515
Removal and InstallationEHS0016Z
The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger
air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-
ness must be modified to allow connection of the service replacement passenger air bag module. Refer to
SRS-51, "
WIRING HARNESS MODIFICATION" for wiring harness modification procedure.
REMOVAL
CAUTION:
Do not attempt to repair or replace damaged direct-connect front passenger air bag module con-
nectors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiring harness modified.
Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least
3 minutes.
Always work from the side of or under front passenger air bag module.
1. Remove the glove box. Refer to IP-10, "
INSTRUMENT PANEL ASSEMBLY" .
2. Remove 2 nuts (through glove box opening) retaining front pas- senger air bag module to instrument panel crossmember.
3. Disconnect the air bag module electrical connectors.
For removal/installation of the direct-connect SRS connec-
tors, refer to SRS-7, "
Direct-connect SRS Component Con-
nectors" .
4. Remove the instrument panel assembly from the vehicle. Refer to IP-10, "
INSTRUMENT PANEL ASSEMBLY" .
5. Remove front passenger air bag module nuts and remove air bag module from the instrument panel assembly.
CAUTION:
When servicing the SRS, do not work from directly in front
of air bag module.
Always place front passenger air bag module with caution
label side facing upward.
Do not insert any foreign objects (screwdriver, etc.) into air
bag module or harness connectors.
Do not disassemble air bag module.
Do not use old nuts after removal; replace with new nuts.
Do not expose the front passenger air bag module to tem-
peratures exceeding 90 °C (194 °F).
Replace the air bag module if it has been dropped or sus-
tained an impact.
Do not allow oil, grease or water to come in contact with the
air bag module.
For removal/installation of the direct-connect SRS connec-
tors, refer to SRS-7, "
Direct-connect SRS Component Con-
nectors" .

Service Replacement Passenger Air Bag Module
1. Install the front passenger air bag module to the instrument
panel pad assembly.
2. Install the instrument panel assembly. Refer to IP-10, "
INSTRUMENT PANEL ASSEMBLY" .
3. Connect the front passenger air bag module harness connector to yellow 4-pin service replacement air bag connector and fasten connector to mounting bracket.

WIRING HARNESS MODIFICATION
The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger
air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-
ness must be modified to allow connection of the service replacement passenger air bag module.
NOTE:
The wiring harness modification is to be performed only if the vehicle is equipped with the original passenger
air bag which uses direct-connect harness connectors. If the passenger air bag is to be replaced in a vehicle
that has already had the service replacement passenger air bag installed, the wiring harness modification is
not required.
CAUTION:
Do not attempt to repair or replace damaged direct-connect front passenger air bag module con-
nectors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiring harness modified.
Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least
3 minutes.
Always work from the side of or under front passenger air bag module.
After the work is completed, perform self-diagnosis to check that no malfunction is detected.
Refer to SRS-20, "
SRS Operation Check" .
1. Locate the yellow and orange direct-connect passenger air bag module harness connectors.
2. Use wire cutters to cut back both previously used direct-connect passenger air bag module harness con- nectors from the vehicle wiring harness approximately 50 mm (1.9 in) from the connectors.
3. Remove approximately 150 mm (5.9 in) of the vehicle harness covering from the cut end.

4. Slide a piece of dual-wall heat shrink tubing (provided in the pas-
senger air bag service kit) onto each wire of the previously used
vehicle wiring harness.
5. Fold each wire back and insert into the end of the heat shrink tubing so that the end of the wire is approximately centered in
the heat shrink tubing.
6. Use a heat gun to shrink the heat shrink tubing and seal the wire.
7. Use electrical tape to secure the modified circuits to the outside of the wiring harness.
8. Locate the front passenger air bag service replacement connec- tor that is taped back to the main harness. Unwrap the tape to
access the yellow service replacement connector and remove
the dust cover from the connector.
