Precautions
Precautions for Steering DiagnosisS6RW0D6100001
Since the problems in steering involve several systems, they must all be considered when diagnosing a complaint. To
avoid using the wrong symptom, always road test the vehicle first. Proceed with the following preliminary inspection
and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect steering system for loose or damaged parts.
3) Spin front wheels. Inspect for out-of-round tires, out-of-balance tires, bent rims, loosen and/or rough wheel
bearings.

General Description
Steering Wheel and Column ConstructionS6RW0D6201001
This double tube type steering column has the following three important features in addition to the steering function:
• The column is energy absorbing, designed to compress in a front-end collision.
• The ignition switch and lock are mounted conveniently on this column.
• With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified screws, bolts and nuts be used as
designated, and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller other than the recommended puller in
this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly could
shear the plastic shear pins which maintain column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is mounted
to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the restraint of the
driver’s and passenger’s seat belts by deploying the air bags. The air bag (inflator) module should be handled with
care to prevent accidental deployment. When servicing, be sure to observe “Precautions on Service and Diagnosis of
Air Bag System in Section 8B”.

3) Install steering column upper cover (1) and lower
cover (2).
CAUTION!
When installing covers, be careful so that
each lead wire is not caught between covers.
Otherwise, each lead wire is damaged.

4) Install steering wheel to steering column. Refer to
“Steering Wheel Removal and Installation”.
5) Connect negative (–) cable to battery.
6) Enable air bag system referring to “Enabling Air Bag
System in Section 8B”.
Centering Contact Coil Cable AssemblyS6RW0D6206004
1) Check that vehicle’s wheels (front tires) are set at
straight-ahead position.
2) Check that ignition switch is at LOCK position.
3) Turn contact coil counterclockwise slowly with a light
force till contact coil will not turn any further.
NOTE
Contact coil can turn about 5 turns at the
maximum, that is, if it is at the center
position, can turn about two and a half turns
both clockwise and counterclockwise.

4) From the position where contact coil became unable
to turn any further (it stopped), turn it back clockwise
about two and a half rotations and align center mark
with alignment mark (1).
Contact Coil Cable Assembly InspectionS6RW0D6206005
Refer to “Contact Coil Cable and Its Circuit Check in
Section 8B”.
Steering Column Removal and InstallationS6RW0D6206008
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.

7) Remove steering column mounting nuts (1), and
then remove steering column from vehicle.
NOTE
Do not move tilt lever until mounting bolts
and nuts are tightened to specified torque.

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 mounting nuts
No.2 (1) first and then steering column mounting
nuts No.1 (2) to specifications as given below.
Tightening torque
Steering column mounting nut No.1 (a): 14 N·m (
1.4 kgf-m, 10.5 lb-ft)
Steering column mounting nut No.2 (b): 14 N·m (
1.4 kgf-m, 10.5 lb-ft)
NOTE
• When installing, make sure that clearance
“a” between bolt (3) and bracket (4) should
be 0 (zero).
• After installing tilt steering column, make
sure that steering column moves upwards
and downwards smoothly and stops when
tilt lever is fixed.

Scan Tool DataS6RW0D6304007
NOTE
When P/S motor is cold condition (that is, armature coil of P/S motor is not heated), normal value with
asterisk (*) mark in the following table is displayed on scan tool

Scan Tool Data Definitions
Power Supply Voltage
This parameter indicates battery positive voltage.
Sensor Power Supply (Torque Sensor Power Supply,
V)
This parameter indicates the power supply voltage which
the P/S control module supplies to the torque sensor.
Sensor (Main) Torque (Torque Sensor Main Torque,
N⋅m)
The torque sensor is installed to detect the steering force
and the steering direction. It consists of two
potentiometers and the main torque sensor is one of
these.
Sensor (Sub) Torque (Torque Sensor Sub Torque,
N⋅m)
The torque sensor is installed to detect the steering force
and the steering direction. It consists of two
potentiometers and the sub-torque sensor is one of
these. Its output characteristics are compared with those
of the main torque sensor.Control Torque (N⋅m)
This parameter is an internal parameter of the P/S
control module. It is obtained by computing the torque
sensor input signal.
Target Motor Current (Motor Control Current, A)
Based on the input signal, the P/S control module
determines the assist amount and controls the current to
the motor suitable for that assist amount. This parameter
indicates that control value.
Measured MOT Current (Motor Monitor Current, A)
This parameter indicates the actually measured value of
the current flowing to the motor. The motor circuit
condition is diagnosed by comparing this parameter with
“Motor Control” parameter described previously.
Vehicle Speed (km/h, MPH)
Vehicle speed signal is fed from BCM. P/S control
module determines the amount of power assist based on
this vehicle speed signal and the torque sensor signal.
Engine Speed (rpm)
Engine speed signal is fed from the ECM so that it can
be used for trouble diagnosis of the electric power
steering system. Scan tool data Vehicle condition Normal condition
