• Check front wheel turning angle after toe-in inspection. Place front wheels on turning radius gauges and rear wheels on stands.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
• With the engine at idle, turn steering wheel from full left stop to full right stop and measure the turning angles.
• Measure rack stroke if angles are outside the specified value.
• Disassemble steering gear assembly to check the cause that rack stroke is outside of the standard.
• Steering angles are not adjustable. Check steering gear assembly, steering column assembly and front suspension components for
wear or damage if any of the turning angles are different from the
specified value. Replace any of them, if any non-standard condi-
tion exists.

STEERING WHEEL
CAUTION:
• After installing steering wheel, perform wheel alignment. Refer to FSU-7, "
Wheel Alignment Inspec-
tion".
REMOVAL
NOTE:
When reconnecting spiral cable, secure cable with a tape so that case and rotating part keep aligned. This will
omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SRS-34, "
Removal and Installation".
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel.

• Align spiral cable correctly when installing steering wheel. Make sure spiral cable alignment and centering marks (B) are matched
and in the neutral position. The neutral position is detected by turn-
ing left 2.5 revolutions from the right end position, ending with the
locating pin (A) at the top. Place steering wheel in straight ahead
position, then install it with the locating pin hole (C) directly over
spiral cable locating pin.
• After the work is completed, perform self-diagnosis to make sure no malfunction is detected. Refer to SRS-19, "
SRS Operation
Check".
• Tighten steering wheel lock nut to specification.

COMPONENT
CAUTION:
• Do not allow axial impact to steering column assembly during removal and installation.
• Steering column must be kept at maximum tilt up position during removal and installation. Do not
operate tilt mechanism while steerin g column is out of the vehicle.
• Put matching mark on intermediate shaft and steering column assembly before removing steering column.
• When steering wheel is turned repeatedly with the vehicle stopped, care must be taken because
motor and EPS control unit may get too hot.
• Steering column assembly is heavy. Care must be taken when removing steering column assembly
from vehicle.
• Do not put steering column assem bly near the things that generate excessive magnetic force.
• Steering column assembly (with motor, redu ction gear, sensor) cannot be disassembled.
• After installing steering column, perform wheel alignment. Refer to FSU-7, "
Wheel Alignment Inspec-
tion".

INSPECTION AFTER REMOVAL
• Check each part of steering column assembly, EPS control unit and intermediate shaft for damage and.
replace as necessary.
• Measure the length (L) as shown, if vehicle has been involved in a minor collision. Replace steering column assembly (with motor,
reduction gear, sensor) if outside the standard.
• Check tilt mechanism for damage or other malfunctions. Replace steering column assembly (with motor, reduction gear, sensor) as
necessary.
• Measure steering column assembly rotating torque using Tool.
Replace steering column assembly (with motor, reduction gear,
sensor) if outside the standard.
INSTALLATION
Installation is in the reverse order of removal.
• Installation is in the reverse order of removal.
• When tightening bolt (intermediate shaft lower side), tight en it by hand first, and make sure there is no feel-
ing of sticking or galling before final tightening.
CAUTION:
Insert bolt in the proper direction. (D o not insert it from the other side.)
• When connecting intermediate shaft upper side (1) and column shaft, make sure the bolt is securely seated in groove (A) of col-
umn shaft (A) before final tightening.
INSPECTION AFTER INSTALLATION
• Rotate steering wheel to check for decentered condition, binding, noise or excessive steering effort.
• After installing steering column assembly, perform self-diagnosis with CONSULT-III to ensure correct opera-
tion. Refer to STC-8, "
CONSULT-III Function".
