Fuel Pressure Relief Procedure
After making sure that engine is cold, relief fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T vehicle), set parking brake, and
block drive wheels.
2) Remove fuel pump relay (1) from its connector.
3) Remove fuel filler cap to release fuel vapor pressure in fuel
tank and then reinstall it.
4) Start engine and run it till it stops for lack of fuel. Repeat
cranking engine 2 – 3 times of about 3 seconds each time to
dissipate fuel pressure in lines. Fuel connections are now
safe for servicing.
5) Upon completion of servicing, install fuel pump relay to relay
box.
Fuel Leakage Check Procedure
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump)
and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pres-
sure to fuel line (till fuel pressure is felt by hand placed on
fuel return hose).
2) In this state, check to see that there are no fuel leakages
from any part of fuel system. CAUTION:
This work must not be done when engine is hot. If done
so, it may cause adverse effect to catalyst.

Idle Speed/Idle Air Control (IAC) Duty Inspec-
tion
Before idle speed/IAC duty check, make sure of the following.
•Lead wires and hoses of engine/emission control systems
are connected securely.
•Accelerator cable is adjusted.
•Ignition timing is within specification.
•All accessories (wipers, heater, lights, A/C, etc.) are out of
service.
•Air cleaner has been properly installed and is in good condi-
tion.
•ECM (PCM) does not detect any malfunction DTC.
After above items are all confirmed, check idle speed and IAC
duty as follows.
[Using SUZUKI scan tool]
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
Special tool
(A) : SUZUKI scan tool
2) Warm up engine to normal operating temperature.
3) Check IAC duty and idle speed by using “Data List” mode of
SUZUKI scan tool.
Engine idle speed:
A/C OFF: 700 ± 50 r/min.
A/C ON: 750 ± 50 r/min.
IAC duty at specified idle speed:
5 – 40 % (at A/C OFF)
4) If duty and/or idle speed is out of specifications, check idle
air control system referring to “DIAG. FLOW TABLE B-4” in
Section 6-1.
5) Check that specified engine idle speed is obtained with A/C
ON if vehicle is equipped with A/C. If not, check A/C ON sig-
nal circuit and idle air control system. NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
vehicle), and set parking brake and block drive wheels.

Fuel cut operation
INSPECTION
1) Warm up engine to normal operating temperature.
2) While listening to sound of injector by using sound scope (1)
or such, increase engine speed to higher than 3,000 r/min.
3) Check to make sure that sound to indicate operation of injec-
tor stops when throttle valve is closed instantly and it is
heard again when engine speed is reduced to less than
about 2,000 r/min. NOTE:
Before inspection, check to make sure that gear shift
lever is in Neutral position (with A/T model, selector lever
in “P” range) and that parking brake lever is pulled all the
way up.

6F2-6 IGNITION SYSTEM (FOR H27 ENGINE)
Ignition Spark Check
1) Remove surge tank cover.
2) Disconnect injector coupler (1).
3) Remove spark plug and check it for condition and type, refer-
ring to “SPARK PLUG” in this section.
4) If OK, connect ignition coil coupler to ignition coil assembly
and connect spark plug to ignition coil assembly. Ground
spark plug.
5) Crank engine and check if each spark plug sparks.
If no spark is emitted, inspect the related parts as described
under “DIAGNOSIS” in this section.
6) After checking, install spark plug, referring to “SPARK PLUG”
in this section.
7) Connect injector coupler (1).
8) Install surge tank cover.
Ignition Timing Check and Adjustment
1) Start engine and warm it up to normal operating tempera-
ture.
2) Make sure that all of electrical loads except ignition are
switched off.
3) Check to be sure that idle speed is within specification.
Refer to Section 6E2.
4) Connect SUZUKI scan tool to DLC (1) with ignition switch
OFF, restart engine and fix ignition timing by using fixed
spark mode of SUZUKI scan tool.
Special tool
(A) : SUZUKI scan tool WARNING:
Without disconnection of injector coupler, combustible
gas may come out from spark plug holes during this test
and may get ignited in engine room.
NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
model), and set parking brake.

AUTOMATIC TRANSMISSION (4 A/T) 7B1-5
Automatic gear shift diagram
Automatic shift schedule as a result of shift control is shown below. In case that select lever is shifted to L at a
higher than 55 km/h or 34 mile/h speed, 2nd or 3rd gear is operated and then down shifts to 1st at a speed lower
than that. No up shift is available in L.
The same as, the select lever is shifted to 2 at a higher than 105 km/h (65 mile/h) speed, 3rd gear is operated
and then down shifts to 2nd at a speed lower than that.
