AUTOMATIC TRANSMISSION BASIC CHECK
This check is very important for troubleshooting when PCM (ECM) has detected no DTC and no abnormality has
been found in visual inspection. Follow the flow table carefully.
STEPACTIONYESNO
1Was “AUTOMATIC TRANSMISSION DIAG. FLOW TABLE”
performed?Go to Step 2.Go to
“AUTOMATIC
TRANSMISSION
DIAG. FLOW
TABLE”.
2Check A / T Fluid.
Warm transmission to normal operating temperature and check
fluid level and contamination referring to “FLUID LEVEL
CHECK” of “ON-VEHICLE SERVICE” in this section.
Is it in good condition?Go to Step 3.Add or change
fluid.
3Check Fluid Pressure Control Cable.
1) Warm up engine to normal operating temperature.
2) Check fluid pressure control cable for play referring to
“FLUID PRESSURE CONTROL CABLE” of “ON-VEHICLE
SERVICE” in this section.
Is it in good condition?Go to Step 4.Adjust.
4Check Select Cable for Adjustment referring to “SELECT
CABLE” of “ON-VEHICLE SERVICE” in this section.
Is it adjusted correctly?Go to Step 5.Adjust.
5Check Transmission Range Sensor (Switch) Circuit for
Operation.
When using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
2) Turn ignition switch ON and check transmission range
signal (P, R, N, D, 2 or L) on display when shifting manual
selector to each range. See Fig. 1.
Is applicable range indicated?
When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals C03-3 C03-4 C03-5 C03-14
Go to Step 6.Go to Step 3 of
DTC P0705
Flow Table.
2) Check voltage at terminals C03-3, C03-4, C03-5, C03-14,
C03-15 and C03-16 for G10 engine model (C02-11, C02-12,
C02-14, C02-15, C02-21 and C02-23 for G13 engine
model) respectively with selector lever shifted to each
range. See Fig. 2.
Taking terminal C03-3 for G10 engine model (C02-11 for
G13 engine model) as an example, is battery voltage
indicated only when selector lever is shifted to “2” range and
0 V for other ranges as shown in Fig. 3?

DTC CONFIRMATION PROCEDURE
WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Turn ignition switch OFF and then ON.
2) Clear DTC and warm up engine to normal operating temperature.
3) Shift selector lever to each of P, R, N, D, 2 and L ranges and hold it there for longer than 5 seconds each.
4) Check for DTC and if no DTC appears on display, proceed to the next step.

a stroke.
5) Keep vehicle at above speed for 5 sec. or longer.
6) Increase vehicle speed to 75 – 90 km / h (45 – 55 mile / h) by depressing accelerator pedal half a stroke and keep

7B-32 AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC)
STALL TEST
This test is to check overall performance of automatic transmission
and engine by measuring stall speed at D and R ranges.
Be sure to perform this test only when transmission fluid is at normal
operating temperature (70–80C / 158–176F) and its level is be-
tween FULL HOT and LOW HOT. (Refer to “Fluid level” in this sec-
tion.)
CAUTION:
Do not run engine at stall more than 5 seconds continuous-
ly, for oil temperature may rise excessively high.
1) Install tachometer.
2) Apply parking brake and block vehicle wheels.
3) Start engine with selector lever shifted to P range.
4) Depress brake pedal.
5) Shift selector lever to D range and depress accelerator pedal ful-
ly while watching tachometer. Read engine rpm quickly when it
has become constant (stall speed).
6) Release accelerator pedal immediately after stall speed is
checked.
7) In the same way, check stall speed at R range.
8) Stall speed should be within following specification.
Stall speed: 2,500 – 2,900 r / min
(For both G10 and G13 engine models)
9) Possible causes for out-of-specification stall speed are as fol-
lows. Check each part which is suspected to be the cause.

LINE PRESSURE TEST
This test is to check oil pressure system for operation by measuring
oil pressure in oil pressure line. Make sure to perform this test only
when transmission fluid is at normal operating temperature.
NOTE:

Make sure that transmission fluid level is between FULL HOT
and LOW HOT marks on oil level gauge at normal operating
temperature which corresponds to 70–80C (155–176F) of
fluid. (Refer to “Fluid level” in this section.)

Check that transmission is free from fluid leakage.
1) With engine at stop, remove plug and connect oil pressure
gauge to plug hole.
Special Tool
(A): 09925-37811-001
2) Install tachometer.
3) Apply parking brake and block vehicle wheels.
4) With selector lever shifted to P range, start engine.
5) Depress brake pedal fully.
6) Shift selector lever to D range and check oil pressure with engine
running at idling speed and at stall speed respectively.
7) Repeat the same check as in step 6) with selector lever shifted
to R range.
CAUTION:
Do not run engine at stall more than 5 seconds continu-
ously, for oil temperature may rise excessively high.
8) If line pressure is within respective specification in table below,
oil pressure system is in good condition.

BODY ELECTRICAL SYSTEM 8-3
KEYLESS ENTRY SYSTEM (IF EQUIPPED)
The keyless entry system uses radio wave. When the button on the transmitter is pressed, a signal is transmitted
in the form of radio wave to the receiver. Then the signal causes the door lock controller to lock and unlock the door.
The door locks can not operated with the transmitter when either of the following conditions applies.

For 2 seconds after the ignition switch is turned from ON to OFF position.

The ignition switch is at ON or START position.

Any door is open.
