CAUTION:

Place a piece of tape across the spiral cable so it will not be

rotated out of 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 2.5 revolutions from the right

end position and ending with the locating pin at the top.

• If equipped with VDC, refer to

BRC-12, "ADJUSTMENT OF

STEERING ANGLE SENSOR NEUTRAL POSITION : Special

Repair Requirement"

(TYPE 1),

BRC-121, "ADJUSTMENT OF

STEERING ANGLE SENSOR NEUTRAL POSITION : Special

Repair Requirement"

(TYPE 2) for steering angle sensor adjust-

ment.

• After the work is completed, perform self-diagnosis to make sure

no malfunction is detected. Refer to

SRC-13, "SRS Operation Check"

• Tighten steering wheel center nut to specification. Refer to

ST-17, "Removal and Installation"

CAUTION:

• The spiral cable may snap due to steering operation if the cable is not installed in the correct posi-

tion.

• 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 neutral position.
