2. Solenoid valve
3. 12V battery
“A”: Side hole (Should be dry)
“B”: Exhausting fluid
AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC) 7B-37
“P” RANGE TEST
1) Stop vehicle on a slope, shift selector lever to P range and at the
same time apply parking brake.
2) After stopping engine, release parking brake lever gradually and
check that vehicle remains stationary.
SHIFT SOLENOID VALVE CHECK
Whenever shift solenoid valves are removed from transmission,
verify their valve function physically before they are reinstalled.
1) Apply oiler to solenoid valve and give compression by hands
and then check to be sure that transmission fluid from oiler does
not come out from side holes of solenoid valve when battery volt-
age is not conducted.
2) Holding the above condition, conduct battery voltage and then
make sure that fluid is exhausted with vigor.
NOTE:
If fluid does not come out with vigor in above step 2) inspec-
tion, do not reuse that solenoid valve.

1. Output shaft speed sensor
1. PCM coupler disconnected
7B-40 AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC)
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.

Coil resistance100 – 300 Ω
Output voltage at 40 km / h
(25 mile / h)Approximately 1 V
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).

3) Disconnect shift solenoid valve coupler from harness.
4) Apply 12 V to each terminal in solenoid valve coupler and check
to be sure that a click sound is heard from each of shift sole-
noid-A and -B.
If no click sound is heard, check lead wire and connections in oil
pan, and then replace applicable shift solenoid-A or B if wire and
connections are in good condition.
If click sound is heard from each of shift solenoids A and B, shift
solenoid electrical circuits are in good condition. Proceed to
“SHIFT SOLENOID VALVE CHECK” previously described in
this section.
THROTTLE POSITION SENSOR CHECK
Check throttle position sensor and its circuit referring to DTC P0121
Flow Table in Section 6 or 6-1.

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).

[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.

DIAGNOSTIC TROUBLE CODE (DTC) CHECK
(IMMOBILIZER CONTROL MODULE)
1) Using analog type voltmeter, connect positive probe to diagnos-
tic output terminal and negative probe to ground of immobilizer
diagnostic coupler with ignition switch turned ON.
2) Read deflection of voltmeter indicator which represents DTC as
shown in example below and write it down. For details of DTC,
refer to Immobilizer Control Module side in “Diagnostic Trouble
Code Table”.
If voltmeter indicator dose not deflect, go to “Diagnostic Flow
Table A”.
NOTE:
If abnormality or malfunction lies in two or more areas, volt-
meter indicates applicable codes three times each.
DIAGNOSTIC TROUBLE CODE (DTC) CHECK (ECM)
[Not using SUZUKI scan tool] (Vehicle equipped with
monitor coupler)
1) Using service wire, ground diagnostic switch terminal in monitor
coupler.
2) Read DTC from flashing pattern of malfunction indicator lamp as
shown in example below and write it down. For details of DTC,
refer to ECM side in “Diagnostic Trouble Code Table”.
If lamp remains ON, go to “Malfunction Indicator Lamp Check”
in Section 6.
NOTE:
If abnormality or malfunction lies in two or more areas, mal-
function indicator lamp indicates applicable codes three
times each.
And flashing of these codes is repeated as long as diagno-
sis terminal is grounded and ignition switch is held at ON
position.
