IGNITION TIMING
NOTE:
Ignition timing is not adjustable. If ignition timing is out of
specification, check system related parts.
Before starting engine, place transmission gear shift lever in
“Neutral” (shift selector lever to “P” range for A / T model),
and set parking brake.
INSPECTION
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
Special Tool
(A): 09931-76011 (SUZUKI scan tool)
(B): Mass storage cartridge
(C): 09931-76030 (16 / 14 pin DLC cable)
2) Start engine and warm it up to normal operating temperature.
3) Make sure that all of electrical loads except ignition are switched
off.
4) Check to be sure that idle speed is within specification.

AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC) 7B-9
OUTPUT SHAFT SPEED SENSOR (A / T VSS)
The output shaft speed sensor consists of a magnetic core with
magnet and coil. It is mounted on transmission case with 0.6 mm
(0.024 in.) air gap between the core end and countershaft gear
tooth.
While the countershaft rotates, magnetic flux is cut by gear tooth
thus a pulse is generated in the sensor coil according to the speed.
And then, the pulse is transmitted to engine control module as
speed signal.
AUTOMATIC SHIFT DIAGRAM
Automatic shift schedule as a result of shift control is shown below. In case that selector lever is shifted to L range
at a higher than 37 km / h (23 mile / h) (G10 engine model), 40 km / h (25 mile / h) (G13 engine model) speed, 2nd
gear is operated and then down shifts to 1st at a speed lower than that. No up shift is available in L range.

Separately from the above inspection, output shaft speed sensor
itself can be checked on its resistance by disconnecting coupler.
NOTE:
Function of output shaft speed sensor can be checked by
measuring generated pulse as voltage.
For its measurement, use an analog type voltmeter while
spinning wheels on lift and with selector lever in “D” range.

SHIFT SOLENOID VALVE CIRCUIT CHECK
1) With ignition switch turned OFF, disconnect PCM couplers.
2) Bring ohmmeter probes in touch with coupler terminals from har-
ness side and measure each resistance.
Resistance between C02-9 and C02-1
for G10 engine model (C03-4 and
C01-1 for G13 engine model)
(Shift solenoid-A, direct clutch) : 8 – 20 Ω
Resistance between C02-8 and C02-1
for G10 engine model (C03-11 and
C01-1 for G13 engine model)
(Shift solenoid-B, 2nd brake) : 8 – 20 Ω
If resistance is out of specification, check shift solenoid itself for
resistance (referring to Step 3 of DTC P0753 / P0756 Flow Table)
and wire harness for open or short.
If resistance is within specification, proceed to step 3).

8G-2 IMMOBILIZER CONTROL SYSTEM
GENERAL DESCRIPTION
The immobilizer control system designed to prevent vehicle burglar consists of following components.
Engine Control Module (ECM)
Immobilizer Control Module
Ignition key (with built-in transponder)
Coil antenna
Operation of this system is as follows.
(1) Each ignition key has its own code (Transponder code) stored in memory. When the ignition switch is turned
ON, Immobilizer Control Module tries to read the Transponder code through the coil antenna installed to the
steering lock assembly.
(2) Immobilizer Control Module compares the Transponder code read in (1) and that registered in Immobilizer Con-
trol Module and checks if they match.
(3) When it is confirmed that two Transponder codes match each other as described above, Immobilizer Control
Module and ECM check if ECM/Immobilizer Control Module codes registered in them respectively match.
(4) Only when it is confirmed that ECM/Immobilizer Control Module codes match, the engine starts running. If
Transponder codes in Step (2) or ECM/Immobilizer Control Module codes in Step (3) do not match, ECM will
stop operation of the injector and the ignitor (i.e., ignition of spark plug).

ON-BOARD DIAGNOSTIC SYSTEM
(SELF-DIAGNOSIS FUNCTION)
Immobilizer Control Module & ECM diagnose troubles which may
occur in the area including the following parts when the ignition
switch is ON.
ECM:ECM/Immobilizer Immobilizer

code Module:Transponder code
Data link connectorCoil antenna
wireECM/Immobilizer
ECM Control Module

Immobilizer
Control Module
Ignition signal
With the diagnosis switch terminal of monitor coupler for ECM not
grounded, the ignition switch turned ON (but the engine at stop) and
regardless of the condition of the engine and emission control sys-
tem, ECM indicates whether a trouble has occurred in the immobi-
lizer control system or not by causing the malfunction indicator lamp
to flash or turn ON.
Malfunction indicator lamp is ON:
No trouble exists in the immobilizer control system.
Malfunction indicator lamp is flashing:
ECM or Immobilizer Control Module has detected some trouble in
the immobilizer control system.
NOTE:
As soon as the ignition switch is turned ON, ECM and Immobi-
lizer Control Module diagnose if a trouble has occurred in the
immobilizer control system. While the diagnosis is being
made, the malfunction indicator lamp stays ON and if the diag-
nosis result is “abnormal”, it immediately changes to flashing
but if the result is “normal”, it remains ON. Diagnosis takes
about 3 seconds at maximum.
IMMOBILIZER CONTROL SYSTEM 8G-7
[INTERMITTENT TROUBLES]
There are cases where output of diagnostic output terminal
and / or malfunction indicator lamp indicate a diagnostic trouble
code representing a trouble which occurred only temporarily and
has gone. In such case, it may occur that good parts are replaced
unnecessarily. To prevent such accident, be sure to follow instruc-
tions given below when checking by using “Diagnostic Flow
Table”.
* When trouble can be identified, it is not an intermittent one:
Check coil antenna, ignition key, wires and each connection
and if they are all in good condition, substitute a known-good
ECM and recheck.
* When trouble can not be identified but output of diagnostic out-
put terminal and / or malfunction indicator lamp indicate a
trouble code:
Diagnose trouble by using that code No. and if ignition key, coil
antenna, wires and each connection are all in good condition,
turn OFF ignition switch and then ON.
Then check what malfunction indicator lamp and / or output of diag-
nostic output terminal indicate.
Only when they indicate trouble code again, substitute a known-
good ECM or Immobilizer Control Module and check again.
If they indicate not trouble code but normal code, it means that an
intermittent trouble did occur and has gone. In this case, check
wires and connections carefully again.
There are cases where output of diagnostic output terminal and /
or Suzuki scan tool indicate a diagnostic trouble code represent-
ing a trouble which occurred only temporarily and has gone. In
such case, it may occur that good parts are replaced unnecessar-
ily. To prevent such accident, be sure to follow instructions given
below when checking by using “Diagnostic Flow Table”.
* When trouble can be identified, it is not an intermittent one:
Check coil antenna, ignition key, wires and each connection
and if they are all in good condition, substitute a known-good
ECM and recheck.
* When trouble can not be identified but output of diagnostic out-
put terminal and / or Suzuki scan tool indicate a trouble code:
Diagnose trouble by using that code No. and if ignition key, coil
antenna, wires and each connection are all in good condition,
turn OFF ignition switch and then ON.
Then check what Suzuki scan tool and / or output of diagnostic out-
put terminal indicate.
Only when they indicate trouble code again, substitute a known-
good ECM or Immobilizer Control Module and check again.
If they indicate not trouble code but normal code, it means that an
intermittent trouble did occur and has gone. In this case, check
wires and connections carefully again.
