Step Action Yes No
1 Check Fan Control System.
1) Connect scan tool to DLC with ignition switch OFF.
2) Start engine and select “DATA LIST” mode on scan
tool.
3) Warm up engine until coolant temp. is 97.5°C, 208°F or
higher and A/C switch turn OFF. (If engine coolant
temp. does not rise, check engine cooling system or
ECT sensor.) See Fig. 1.
Is radiator cooling fan started when engine coolant temp.
reached above temp.?Radiator cooling fan
control system is in
good condition.Go to Step 2.
2 Check Radiator Fan Relay and Its Circuit.
1) Check DTC and pending DTC with scan tool.
Is DTC P0480 displayed?Go to DTC P0480 Diag.
Flow Table.Go to Step 3.
3 Check Radiator Fan Relays.
1) Turn ignition switch OFF and remove radiator cooling
fan relays. (No.1 – No.3)
2) Check for proper connection to relay at terminals “c”
and “d”.
3) If OK, check that there is continuity between “c” and “d”
when battery is connected to terminals “a” and “b”. See
Fig. 2.
Is check result satisfactory?Go to Step 4. Replace radia-
tor fan relay(s).

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System :
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

DIAGNOSIS
DIAGNOSIS TABLE
Refer to “ENGINE MECHANICAL DIAGNOSIS TABLE” in Sec-
tion 6.
COMPRESSION CHECK
Check compression pressure on all 4 cylinders as follows:
1) Warm up engine to normal operating temperature.
2) Stop engine after warming up.
3) Remove air cleaner assembly (1), resonator (2) and hoses.
Refer to “AIR CLEANER ASSEMBLY AND RESONATOR”.
4) Remove cylinder head upper cover (1).
5) Disconnect ignition coil couplers (1).
6) Remove ignition coil assemblies (2) with high-tension cord
(3).
7) Remove all spark plugs.
8) Disconnect fuel injector wires (4) at the coupler.NOTE:
After warming up engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
model), and set parking brake and block drive wheels.

6A1-6 ENGINE MECHANICAL (M13 ENGINE)
13) After checking, install spark plugs and ignition coil assem-
blies (1) with high-tension cord (2).
14) Connect ignition coil couplers (3).
15) Connect fuel injector wires(4) at the coupler.
16) Check cylinder head upper cover gasket for deterioration
and then install it into groove of cylinder head upper cover
(1) securely.
17) Install cylinder head upper cover with gasket on to cylinder
head cover.
18) Install air cleaner assembly, resonator and hoses referring to
“AIR CLEANER ASSEMBLY AND RESONATOR”.
ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indi-
cator of the condition of the engine. The vacuum checking proce-
dure is as follows :
1) Warm up engine to normal operating temperature.
2) Stop engine and turn off the all electric switches.
3) Remove cap (1) from intake manifold.
NOTE:
After warming up engine, be sure to place transmission
gear shift lever in “Neutral” (shift selector lever to “P”
range for A/T model), and set parking brake and block
drive wheels.
