Steering Column Removal and InstallationS7RS0B6206006
CAUTION!
Once the steering column is removed from
the vehicle, the column is extremely
susceptible to damage.
• Dropping the column assembly on its end could collapse the steering shaft or loosen
the plastic shear pins which maintain
column length.
• Leaning on the column assembly could cause it to bend or deform.
Any of the damage could impair the column’s
collapsible design.
Steering column mounting nuts should not
be loosened with steering shaft joint upper
side bolt tightened as this could cause
damage to shaft joint bearing.

NOTE
When servicing steering column or any
column-mounted component, remove
steering wheel. But when removing steering
column simply to gain access to instrument
panel components, leave steering wheel
installed on steering column.

Removal
WARNING!
Never rest a steering column assembly on
the steering wheel with the air bag (inflator)
module face down and column vertical.
Otherwise, personal injury may result.

1) Disconnect negative (–) cable at battery.
2) Disable air bag system. Re fer to “Disabling Air Bag
System in Section 8B”.
3) Remove steering wheel and contact coil cable assembly referring to “S teering Wheel Removal and
Installation” and “Contact Coil Cable Assembly
Removal and Installation”.
4) Detach lighting switch and wiper switch from steering column.
5) Remove immobilizer cont rol module from steering
column, referring to “Immo bilizer Control Module
(ICM) Removal and Installation in Section 10C”.
6) Remove steering column hole cover.
7) Remove steering joint cover.
8) Make alignment marks (4) on lower shaft (1) and shaft joint of steering column (2) and lower shaft (1)
and pinion shaft (3) for a guide during reinstallation.
9) Remove lower shaf t joint bolts (5).
10) Remove steering lower shaft (1).
11) Remove steering column mounting nuts (1).
12) Remove steering column from vehicle.

Installation
CAUTION!
After tightening steering column mounting
nuts, shaft joint bolts should be tightened.
Wrong tightening order could cause a
damage to shaft joint.

1) Be sure that front wheels are in straight.
2) Install steering column assembly to lower and upper brackets. Tighten steering column lower nuts (1) first
and then upper nuts (2) to specifications as given
below.
Tightening torque
Steering column nut (a): 14 N·m (1.4 kgf-m, 10.5
lb-ft)
NOTE
After installing tilt steering column, make
sure that steering column moves backwards
and forwards smoothly and stops when tilt
lever is fixed.

3) Align flat part “A” of stee ring lower shaft (1) with bolt
hole “B” of shaft joint (2) of column as shown. Then
insert lower shaft into shaf t joint of steering column
with matching marks (4).
4) Insert lower shaft (1) into pinion shaft (3) with matching marks (4).
5) Tighten joint bolt (pinion shaft side) (6) to specified torque first and then joint bolt (steering column side)
(5) to specified torque.
CAUTION!
After tightening column nuts, tighten steering
shaft upper joint bolt. Otherwise shaft joint
bearing is damaged.

Tightening torque
Steering shaft joint bolt (a): 25 N·m (2.5 kgf-m,
18.5 lb-ft) 6) Install steering joint cover.
7) Install immobilizer cont
rol module from steering
column, referring to “Immo bilizer Control Module
(ICM) Removal and Installation in Section 10C”.
8) Install lighting switch and wiper switch to steering column.
9) Install contact coil cable assembly and steering wheel referring to “Conta ct Coil Cable Assembly
Removal and Installation” and “Steering Wheel
Removal and Installation”.
10) Install steering column hole cover. 11) Connect negative (–) battery to cable.
12) Enable air bag system refe rring to “Enabling Air Bag
System in Section 8B”.
Steering Column InspectionS7RS0B6206007
Check steering column for damage and operation
referring to “Checking Steering Column for Accident
Damage”.

EPS Diagnosis General DescriptionS7RS0B6301002
The P/S system in this vehicle is controlled by the P/S control module. T he P/S control module has an on-board
diagnostic system which detects a malfunction in this system. When diagnosing troubles, be sure to have full
understanding of the outline of “On-Board Diagnostic Sy stem Description” and each item in “Precautions in
Diagnosing Troubles”, and then execute diagnosis according to “EPS System Check”.
On-Board Diagnostic System DescriptionS7RS0B6301003
The P/S control module performs the on -board diagnosis (self-diagnosis) on the system and operates the “EPS”
warning light (1) as follows.
• The “EPS” warning light lights when the ignition switch is turned to ON position (but the engine at stop) regardless
of the condition of the P/S co ntrol system. This is only to check if the “EPS” warning light is operated properly.
• If the areas monitored by the P/S control module is free from any trouble after the engine start (while engine is
running), the “EPS” warning light turns OFF.
• When the P/S control module detects a trouble which has occurred in th e monitored areas the “EPS” warning light
comes ON while the engine is running to warn the driver of such occurrence of the trouble and at the same time it
stores the exact trouble area in memory inside of the P/S control module.
Driving Cycle
A “Driving Cycle” consists of en gine startup and engine shutoff.
3 Driving Cycles Detection Logic
The malfunction detected in the first and second driving cycl e is stored in P/S control module memory (in the form of
pending DTC) but the “EPS” wa rning light does not light at these time. It lights up at t he third detection of same
malfunction also in the next driving cycle.
