REMOVAL
1. Disconnect battery around cable.
2. Remove airbag module.
WARNING: Always refer to "Airbag System" before performing airbag module service (if so equipped).
3. Remove steering wheel nut, then draw out steering wheel from shaft using steering puller.

4. Remove the screw securing lower steering column cover.
5. Remove two screws securing upper steering column cover.
6. Release the lock of harness band and disconnect connector of steering angle sensor.
7. Remove bolts which hold roll connector and steering angle sensor onto steering column.
8. Remove roll connector and steering angle sensor.
NOTE: Do not turn steering angle sensor as it's center position has been recognized by VDCCM.
INSTALLATION
CAUTION: Ensure that front wheels are set in straight forward direction.
1. Place steering angle sensor on steering column, confirming that the sensor is positioned as in the figure.
2. Conduct centering of roll connector.
3. Place roll connector over steering angle sensor and tighten bolts which secure roll connector and steering angle sensor.
4. Tighten bolts which install roll connector and steering angle sensor onto steering column.
5. Set steering wheel to neutral and install it onto steering shaft.
Tightening torque: 44 Nm (4.5 kgf-m, 32.5 ft. lbs.)
Column cover-to-steering wheel clearance: 2 - 4 mm (0.08 - 0.16 inch)
CAUTION: Insert roll connector guide pin into guide hole on lower end of surface of steering wheel to prevent damage. Draw out airbag system connector, horn connector and cruise control connectors from guide hole of steering wheel lower end.
6. Install airbag module to steering wheel.
WARNING: Always refer to "Airbag System" before performing the service operation.
7. Connect battery ground cable.
CAUTION: After completion of installation procedure, the following two position settings must be made.
^ Steering angle sensor center positioning
^ Yaw rate and lateral G sensor 0 positioning
Programming and Relearning
These procedures are necessary for VDCCM to later recognize what position the vehicle is in.
