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 select lever to each range.
Is applicable range indicated?
When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals C51-1-15, C51-1-16,
C51-1-17, C51-1-18, C51-1-27 and C51-1-28 for
G16/J20 (C51-1-4, C51-1-3, C51-1-13, C51-1-12,
C51-1-20 and C51-1-19 for H25) respectively with
select lever shifted to each range.
Taking terminal C51-1-28 for G16/J20 (C51-1-20 for
H25) as an example, is battery voltage indicated
only when select lever is shifted to ª2º range and
0 V for other ranges as shown in figure?

Is OFF / ON displayed as described above?
When not using SUZUKI scan tool:
1) Remove PCM cover.
2) Turn ignition switch ON.
3) Check voltage at terminal C51-1-26 for G16 / J20
(C51-1-5 for H25) of PCM connector connected
when shifting transfer lever to each position.
4H or 2H position : 10 ± 14 V

4WD Low Switch Inspection
1) Disconnect negative cable at battery.
2) Disconnect 4WD low switch coupler.
3) Check continuity between 4WD low switch terminals.
There should be continuity when transfer lever shifted to 4L posi-
tion and should be infinity when transfer lever shifted to 4H or 2H

STALL TEST
This test is to check overall performance of automatic transmission
and engine by measuring stall speed at ªDº and ªRº ranges. Be sure
to perform this test only when transmission fluid is at normal operat-
ing temperature and its level is between FULL and LOW marks.
CAUTION:

Do not run engine at stall more than 5 seconds continu-
ously, for fluid temperature may rise excessively high.

After performing stall test, be sure to leave engine running
at idle for longer than 30 seconds before another stall test.
1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to ªPº.
4) Depress brake pedal fully.
5) Shift select lever to ªDº and depress accelerator pedal fully while
watching tachometer. Read engine rpm quickly when it has be-
come constant (stall speed).
6) Release accelerator pedal immediately after stall speed is
checked.
7) In the same way, check stall speed in ªRº range.

ROAD TEST
This test is to check if upshift and downshift take place at specified
speed while actually driving vehicle on a level road.
WARNING:

Carry out test in very little traffic area to prevent an acci-
dent.

Test requires 2 persons, a driver and a tester.
1) Warm up engine.
2) With engine running at idle, shift select lever ªDº.
3) Accelerate vehicle speed by depressing accelerator pedal grad-
ually.
4) While driving in ªDº range, check if gear shift occurs properly as
shown in Gear Shift Diagram in this section.

BRAKE INTERLOCK SYSTEM
SHIFT LOCK SOLENOID CONTROL
This system consists of shift lock solenoid control system and inter-
lock cable control system.
The shift lock solenoid control system is so designed that the selec-
tor lever can not be shifted from ªPº range position unless the igni-
tion switch is turned ON and the brake pedal is depressed. And the
interlock cable control system is so designed that the selector lever
cannot be shifted from ªPº range position unless the ignition switch
is turned to ªACCº or ªONº position. Also, the ignition key cannot be
pulled out of the key slot unless the selector lever is in ªPº range.
SHIFT LOCK SOLENOID CONTROL OPERATIONS
When the select lever is in ªPº range, the ignition key position is
ªONº and depressing the brake pedal cause the electric current to
flow to the solenoid. As the shift lock solenoid rod (or the lock plate)
is drawn toward the solenoid in this state, it frees the interlock cam
(or the detent pin), which then allows the select lever to be shifted
from ªPº range to any other position.
Even when the select lever is in ªPº range, if the ignition key position
is ªLOCKº or ªACCº or the brake pedal is not depressed, the electric
current does not flow to the solenoid.
In this state, the shift lock solenoid rod (or the lock plate) is pushed
away from the solenoid by spring force and it obstructs the interlock
cam (or the detent pin) movement. Thus the select lever button
does not work even when pressed and the select lever shift is pre-
vented.
