WARNING:
The following service operations include the works which may affect the SRS airbag system. Before starting work, always be sure to confirm the precautions related to the SRS airbag system. (Refer to )
1. Check of the straight-ahead position of the front tire
2. Precautions
CAUTION:
After turning the ignition switch to OFF, you may have to wait for a while before disconnecting the battery terminals. Check appropriate precautions for battery terminal disconnection before proceeding. (Refer to )
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.

5. Removal of the steering column cover support (with smart entry) (Refer to )
6. Removal of the steering column cover LWR (Refer to )
7. Removal of the steering column cover UPR (Refer to )
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.

(3) Release 3 claws, and remove the steering roll connector SUB-ASSY (with the steering sensor).
INSPECTION
1. Inspection of the steering roll connector SUB-ASSY (with the steering sensor)
(1) When the following conditions are found, replace the steering roll connector SUB-ASSY (with the steering sensor) with a new one.
Criteria
·There are scratches, cracks, or damages in the connector.
·There are cracked, dented, or chipped parts.
·When rotating the connector, it does not move smoothly and makes noise.
·The connector can not be centered.
INSTALLATION
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.
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).
4. Installation of the steering column cover LWR (Refer to )
5. Installation of the steering column cover support (with smart entry) (Refer to )
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.

UNIT INSPECTION
1. Inspection of the steering roll connector SUB-ASSY (with the steering sensor)
CAUTION:
·Do not rotate the roll connector to more than the specified number of turns. Otherwise, the roll connector internal wire may be broken.
·When determining the end stop, rotate the connector slowly without applying excessive force. Applying excessive force at the end stop may break the internal wire.
(1) Adjust the roll connector.
(2) Set the roll connector to the central position.
(3) Connect the test harness to the connector E.

(4) With the following conditions, check the resistance between the test harness connector terminals.
·Perform the check with the roll connector in the central position (the front wheels are in the straight-ahead position).
·Rotate the roll connector counterclockwise from the central position (the front wheels are in the straight-ahead position) to an end stop. Then, perform the check while rotating it clockwise to approximately 4.5 turns.
