5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Steering SystemINFOID:0000000005396930
• In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle
condition, and then check wheel alignment.
• Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is im portant to prevent the internal parts from becoming
contaminated by dirt or other foreign matter.
- For easier and proper assembly, place disassembled parts in order on a parts rack.
- Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with
their operation.
- Do not reuse non-reusable parts.
- Before assembling, apply the specif ied grease to the directed parts.

On-Vehicle Inspection and ServiceINFOID:0000000005396934
CHECKING CONDITION OF INSTALLATION
• Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
• Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
• Check steering gear assembly mounting bolts and nuts for looseness. Refer to PS-12, "
Removal and Instal-
lation".
CHECKING STEERING WHEEL PLAY
• Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on the
outer circumference.
• When the measurement value is outside the standard val ue, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
• Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the correct position.
• Perform neutral position inspection after wheel alignment. Refer to SRS-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"".
• Set vehicle to the straight-ahead position and c onfirm steering wheel is in the neutral position.
• Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steer-
ing wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Check steering wheel turning force when steering wheel has
been turned 360 ° from neutral position using Tool as shown.
4. If steering wheel turning force is out of the specification, refer to STC-27, "
Diagnosis Procedure".
CHECKING FRONT WHEEL TURNING ANGLE
Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Tool number : — (J-44372)
Steering wheel
turning force : Less than 36 N (3.7 kg-f, 8.2 lb-f)

• 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.

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 front wheels to straight-ahead position.
2. Remove driver air bag module. Refer to SRS-34
.
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel.

STEERING WHEEL
• Align spiral cable correctly when installing steering wheel. Makesure spiral cable alignment and centering marks (B) are matched
and in the neutral position. The neutra l 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".

CAUTION:
• Do not allow axial impact to steering colu mn 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 steeri ng column is out of the vehicle.
• Put matching mark on intermediate shaft and st eering column assembly before removing intermedi-
ate shaft.
• When steering wheel is turned re peatedly 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, reduc tion gear, sensor) cannot be disassembled.
• Any time the ignition switch h as been removed and installed, the keys must be re-registered in the
BCM. Refer to CONSULT–III ope ration manual IVIS/NVIS.
REMOVAL
1. Set front wheels to straight ahead-position.
2. Remove spiral cable. Refer to SRS-37
.
3. Remove instrument lower finisher. Refer to IP-11, "
Component Parts".
4. Disconnect each switch connector installed to steering column assembly, and then disconnect harness from steering column assembly.
5. Remove bolt of intermediate shaft (upper side), and then remove intermediate shaft from steering column assembly.

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.
• When tightening bolt (intermediate shaft lower side), tighten 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. (Do 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 before final tightening.
INSPECTION AFTER INSTALLATION
• Rotate steering wheel to check for decentered conditi on, 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".
