Suzuki Grand Vitara JB627. Manual — part 257

6B-4 Steering Wheel and Column:

• Check steering shaft for smooth rotation.

If found defective, replace as column assembly.

• Check steering shaft and column for bend, cracks or

deformation.
If found defective, replace as column assembly.

• Check steering upper shaft lower seal for breakage or

deformation.
If found defective, replace.

• Check steering shaft joints and shaft for any damages

such as crack, breakage, malfunction or excessive
play.
If anything is found faulty, replace steering upper shaft
assembly, steering lower shaft assembly or steering
column assembly.

• Check steering upper shaft assembly for following

conditions.
– Steering upper shaft assembly (1) is not bent or

damaged.

– Lower seal (2) is not damaged.
– Upper joint (3) turns with light hand force and lower

joint (4) turns at the same time.

– Shaft (1) expands and contracts easily with light

force.

– When shaft is made to contract with light force until

it stops, its length “a” is longer than specified value.

CAUTION

!

Do not apply excessive force to shaft when
making it contract. Its internal plug may be
damaged.

Steering upper shaft assembly length
“a”: 363.0 mm (14.29 in.)

NOTE
If shaft has come off in sleeve due to an
accident or some other reason as shown in
figure, its internal plug has come off or been
damaged. The same applies when length of
steering upper shaft assembly is short.
When anything faulty is noted in above
check, replace steering upper shaft assembly
with a new one.

Steering Wheel Removal and Installation

S6JB0B6206002

CAUTION

!

Removal of the steering wheel allows the
contact coil cable assembly to turn freely but
do not turn the contact coil cable assembly
more than allowable number of turns (about
two and a half turns from the center position
clockwise or counterclockwise respectively),
or coil will break.

Removal

1) Remove driver air bag (inflator) module from

steering wheel referring to “Driver Air Bag (Inflator)
Module Removal and Installation in Section 8B”.

2) Disconnect horn connector and audio control switch

connector, if equipped.

3) Remove steering shaft nut.
4) Make alignment marks (1) on steering wheel and

shaft for a guide during reinstallation.

5) Remove steering wheel (1) with special tool.

CAUTION

!

Do not hammer the end of the shaft.
Hammering it will loosen the plastic shear
pins which maintain the column length and
impair the collapsible design of the column.

Special tool
(A): 09944–36011

Installation

1) Check that vehicle’s front tires are at straight-ahead

position and contact coil cable assembly is centered.
Refer to “Centering Contact Coil Cable Assembly”.

CAUTION

!

These two conditions are prerequisite for
installation of steering wheel. If steering
wheel has been installed without these
conditions, contact coil cable assembly will
break when steering wheel is turned.

2) Install steering wheel (1) to steering shaft with 2 lugs

(2) on contact coil cable assembly fitted in two
grooves (3) in the back of steering wheel and also
aligning marks (4) on steering wheel and steering
shaft.

3) Tighten steering shaft nut to specified torque.

Tightening torque
Steering shaft nut: 33 N·m (3.3 kgf-m, 24.0 lb-ft)

4) Connect horn connector and audio control switch

connector, if necessary.

5) Install driver air bag (inflator) module to steering

wheel. Refer to “Driver Air Bag (Inflator) Module
Removal and Installation in Section 8B”.

3) Remove steering column cover screws (1) (3

pieces).

4) Separate upper cover (2) and lower cover (3), then

remove them.

5) Disconnect all connectors for contact coil cable

assembly.

6) Remove contact coil cable assembly (1) with

steering angle sensor (ESP

® model) from steering

column.

7) (ESP

® model)

Separate steering angle sensor from contact coil
cable assembly referring to “Steering Angle Sensor
Removal and Installation (ESP

® Model)”.

Installation

1) Check to make sure that vehicle’s front tires are set

at straight-ahead position and then ignition switch is
at “LOCK” position.

2) (ESP

® model)

Install steering angle sensor to contact coil cable
assembly refer to “Steering Angle Sensor Removal
and Installation (ESP

® Model)”.

3) Install contact coil cable assembly to steering

column noting the following.
• Fit lower fitting part first and then fit upper fitting

part.

NOTE
New contact coil cable assembly is supplied
with contact coil cable assembly set and held
at its center position with a lock pin (1).
Remove this lock pin after installing contact
coil cable assembly to steering column.

4) Connect all connectors that have been removed in

“Removal”.

5) Install steering column upper cover (2) and lower

cover (3), and then tighten steering column cover
screws (1).

CAUTION

!

When installing lower cover (3) and upper
cover (2), be careful so that each lead wire is

Contact Coil Cable Assembly Inspection

S6JB0B6206004

CAUTION

!

Do not turn contact coil cable assembly more
than allowable number of turns (about two
and a half turns from the center position
clockwise or counterclockwise respectively),
or coil will break.

Check contact coil cable assembly (1) wire harness for
any signs of scorching, melting or other damage.
If it is damaged, replace.

Centering Contact Coil Cable Assembly

S6JB0B6206005

CAUTION

!

Removal of the steering wheel allows the
contact coil cable assembly to turn freely but
do not turn the contact coil cable assembly
more than allowable number of turns (about
two and a half turns from the center position
clockwise or counterclockwise respectively),
or coil will break.

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 cable assembly (2)

counterclockwise slowly with a light force till contact
coil cable assembly will not turn any further.

NOTE
Contact coil cable assembly can turn about 5
turns at 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 cable assembly

(2) 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).
