DISMOUNTING
1) Disconnect distributor lead coupler.
2) Remove distributor cap screws and cap.
3) Remove distributor flange bolts.
4) Pull out distributor housing assembly.
REMOUNTING
NOTE:

Before installing distributor, check to make sure that its
O-ring is in good condition.

If new O-ring is installed, apply oil.
1) Install distributor without cap to camshaft.
Fit the dogs of distributor coupling into the slots of camshaft,
when installing. The dogs of distributor coupling are offset.
Therefore, if the dogs can not shaft by 180 degree and try again.
2) Lightly install flange bolts and prepare for ignition timing adjust-
ment.
3) Check to make sure that rotor is in good condition.
4) Inspect distributor cap and clean or replace as required.
5) Make sure that distributor cap seal is placed properly and install
cap, and then fasten it with screws.
6) Connect distributor lead coupler.
7) Check and adjust ignition timing as previously outlined.

IGNITION SYSTEM DIAGNOSTIC FLOW TABLE
STEPACTIONYESNO
1
Was “ENGINE DIAG. FLOW TABLE” performed?Go to Step 2.Go to “ENGINE DIAG.
FLOW TABLE” in
section 6.
2
Ignition Spark Test
1) Check all spark plugs for condition and type
referring to “Spark Plugs” section.
2) If OK, perform ignition spark test, referring to
“Ignition Spark Test” section.
Is spark emitted from all spark plugs?Go to Step 11.Go to Step 3.
3
Diagnostic Trouble Code (DTC) Check
Is DTC stored in ECM (PCM)?Go to applicable DTC
Diag. Flow Table in
section 6.Go to Step 4.
4
Electrical Connection Check
1) Check ignition coil assemblies and high-tension
cords for electrical connection.
Are they connected securely?Go to Step 5.Connect securely.
5
High-Tension Cords Check
1) Check high-tension cord for resistance referring
to “High-Tension Cords” section.
Is check result satisfactory?Go to Step 6.Replace high-tension
cord(s).
6
Ignition Coil Assembly Power Supply and Ground
Circuit Check
1) Check ignition coil assembly power supply and
ground circuits for open and short.
Are circuits in good condition?Go to Step 7.Repair or replace.
7
Ignition Coil Assembly Check
1) Check ignition coil for resistance referring to
“Ignition Coil Assembly” section.
Is check result satisfactory?Go to Step 8.Replace ignition coil
assembly.
8
Crankshaft Position (CKP) Sensor Check
1) Check crankshaft position sensor referring to
Step 3 and 4 of DTC P0335 Diag. Flow Table in
section 6.
Is check result satisfactory?Go to Step 9.Tighten CKP sensor
bolt, replace CKP
sensor or crankshaft
timing belt pulley.
9
Ignition Trigger Signal Circuit Check
1) Check ignition trigger signal wire for open, short
and poor connection.
Is circuit in good condition?Go to Step 10.Repair or replace.
10
A Known-good Ignition Coil Assembly Substitution
1) Substitute a known-good ignition coil assembly
and then repeat Step 2.
Is check result of Step 2 satisfactory?Go to Step 11.Substitute a known-
good ECM (PCM) and
then repeat Step 2.
11
Ignition Timing Check
1) Check initial ignition timing and ignition timing
advance referring to “Ignition Timing” section.
Is check result satisfactory?System is in good
condition.Check CKP sensor,
crankshaft timing belt
pulley (signal rotor)
and input signals
related to this system.

5) Fix ignition timing to initial one as follow.
Select “MISC” mode on SUZUKI scan tool and fix ignition tim-
ing to initial one.
6) Detach air cleaner case and shift air cleaner case and hose
position to observe ignition timing.
7) Using timing light (1), check that ignition timing is within specifi-
cation.
Initial ignition timing (fixed with
SUZUKI scan tool) : 5
3 BTDC at idle speed
Ignition order : 1-3-4-2
8) If ignition timing is out of specification, check the followings:

CKP sensor

Crankshaft timing belt pulley (signal rotor)

TP sensor

VSS

Timing belt cover installation
9) After checking Initial Ignition Timing, release ignition timing
fixation by using SUZUKI scan tool.
10) With engine idling (throttle opening at closed position and ve-
hicle stopped), check that ignition timing is about 9–15
BTDC. (Constant variation within a few degrees from 9–15
indicates no abnormality but proves operation of electronic tim-
ing control system.) Also, check that increasing engine speed
advances ignition timing.
If above check results are not satisfactory, check CKP sensor
and ECM (PCM).
11) Install air cleaner case.
