REMOVAL
1. Check of the straight-ahead position of the front tire
2. Precautions
3. Disconnection of the battery ground terminal
(1) Turn the ignition switch to OFF, disconnect the battery ground terminal, and then wait for 60 seconds before starting the work. (Refer to
)
WARNING:
The air bag and pretensioner system are fitted with a backup power supply. If you start the work within 60 seconds after disconnecting the battery ground terminal, the air bag may be activated.
CAUTION:
To avoid damage to the molding, be sure to fully open the door glasses on both driver’s and passenger’s sides.
8. Removal of the steering roll connector SUB-ASSY (with the steering sensor)
CAUTION:
·Do not replace the steering roll connector when the ignition switch is turned to ON and the battery is connected.
·Do not rotate the steering roll connector when the ignition switch is turned to ON and the battery is connected.
·When the steering sensor is rotated for its operation check (noise check, diagnosis, etc.), make sure to confirm the vehicle is in the straight-ahead position, then perform the check with the steering wheel installed.
·Do not rotate the steering roll connector when the ignition switch is turned to ON and the battery is connected.
·When the steering sensor is rotated for its operation check (noise check, diagnosis, etc.), make sure to confirm the vehicle is in the straight-ahead position, then perform the check with the steering wheel installed.
(1) Slide the slider to disconnect the airbag connector from the steering roll connector SUB-ASSY (with the steering sensor).

9. Removal of the steering roll connector
CAUTION:
·Remove the steering roll connector only when replacing itself or the steering sensor.
·Do not rotate the center part of the steering sensor, because it may displace the neutral position of the steering sensor.
·Do not rotate the center part of the steering sensor, because it may displace the neutral position of the steering sensor.

·The connector can not be centered.
INSTALLATION
1. Installation of the steering roll connector
2. Installation of the steering roll connector SUB-ASSY (with the steering sensor)
CAUTION:
·Do not replace the steering roll connector when the ignition switch is turned to ON and the battery ground terminal is connected.
·Do not rotate the steering roll connector when the ignition switch is turned to ON and the battery ground terminal is connected.
·When the steering sensor is rotated for its operation check (noise check, diagnosis, etc.), make sure to confirm the vehicle is in the straight-ahead position, then perform the check with the steering wheel installed.
·Do not rotate the steering roll connector when the ignition switch is turned to ON and the battery ground terminal is connected.
·When the steering sensor is rotated for its operation check (noise check, diagnosis, etc.), make sure to confirm the vehicle is in the straight-ahead position, then perform the check with the steering wheel installed.
NOTE:
When the steering roll connector SUB-ASSY (with the steering sensor) is to be replaced with a new one, do not pull off the lock pin of the steering roll connector at this point.
(1) Put the turn signal switch in the neutral position.
CAUTION:
Make sure to put the turn signal switch in the neutral position. Otherwise, the pin of this switch may be broken.
(2) Engage 3 claws to install the steering roll connector SUB-ASSY (with the steering sensor).
(3) Connect each connector to the steering roll connector SUB-ASSY (with the steering sensor).
6. Check of the straight-ahead position of the front tire
7. Centering adjustment of the steering roll connector
CAUTION:
Do not rotate the steering roll connector when the ignition switch is turned to ON and the battery ground terminal is connected.
(1) If the steering roll connector SUB-ASSY (with the steering sensor) is replaced with a new one, remove the lock pin of the steering roll connector.
(2) Check that the ignition switch is turned to OFF.
(3) Check that the battery ground terminal is disconnected.
CAUTION:
After disconnecting the battery ground terminal, do not start the work before waiting for 60 seconds.
(4) Confirm that the steering roll connector SUB-ASSY (with the steering sensor) is in its central position.

NOTE:
When the steering roll connector SUB-ASSY (with the steering sensor) is in its central position, the alignment marks are aligned and the colored part is visible as shown in the figure.
(5) If the steering roll connector SUB-ASSY (with the steering sensor) is not in its central position, perform the centering adjustment of the steering roll connector SUB-ASSY (with the steering sensor).
CAUTION:
·Do not rotate the steering roll connector SUB-ASSY (with the steering sensor) when the ignition switch is turned to ON and the battery is connected.
·Rotate the steering roll connector SUB-ASSY (with the steering sensor) softly without applying force, to prevent the connector internal wire from being broken.
·Do not rotate the steering roll connector SUB-ASSY (with the steering sensor) holding the connector and the wiring of the airbag.
·Do not rotate the steering roll connector SUB-ASSY (with the steering sensor) to more than the specified number of turns. It may break the roll connector internal wire.
