8Check ignition timing
1) Using SUZUKI scan tool, select “Misc Test” mode on
SUZUKI scan tool and fix ignition timing to initial one.
2) Using timing light (1), check initial ignition timing. Special tool
(A): 09930–76420
Is it 5
°± 3° BTDC at specif ied idle speed? Go to “Engine Symptom
Diagnosis”.
Check ignition control
related parts referring to
“Ignition Timing
Inspection in Section
1H”.
9 Check immobilizer system malfunction
1) Check immobilizer indica tor lamp for flashing.
Is it flashing when ignition switch is turned to ON position? Go to “Diagnostic
Trouble Code (DTC)
Check in Section 10C”.
Go to Step 10.
10 Check fuel supply
1) Check to make sure that enough fuel is filled in fuel tank.
2) Turn ON ignition switch for 2 seconds and then OFF.
3) Repeat Step 2) a few times.

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”.

Removal and Installation
S7RS0B6206009
Removal
1) Remove steering column. Refer to “Steering Column
Removal and Installation”.
2) Using center punch (1), loosen and remove steering lock mounting bolts (2).
NOTE
Use care not to damage aluminum part of
steering lock body with center punch.
