SELF-DIAGNOSIS
Warning to the driver
• When trouble has occurred to throttle position sensor, output
revolution sensor, input revolution sensor, neutral star t
switch, engine revolution signal, speed meter signal, or
solenoids, "CHECK TRANS" lamp is blinked (1.25 Hz) even
during driving to warn the driver.
• The trouble is recorded by trouble code in TCM.
• When temporary trouble has been shooted, the "CHECK
TRANS" lamp stops blinking. This blinking can be stopped
by setting the ignition key off. But the trouble code remains
memorized in TCM.
Self-diagnosis code (Flashing code) display
• For quick search for faulty parts, 12 different items of trouble
code are indicated by "CHECK TRANS" lamp blinking.
• The storaged trouble codes can be identified by shor ting the
terminals No. 11 and No. 4 or 5 (ground) of data link
connector with a lead wire.

Indication Method:
1.Terminals No. 11 are No. 4 or 5 (ground) of data link
connector are short circuited.
2. Turn the ignition key to the ON position.
3. In case there no trouble, normal code is indicated.
4. In case a plurality of trouble codes have occurred at a time,
each code is indicated three times in numerical order.
NOTE:
Power line runs through data link connector.
Be careful shorting with a lead wire, etc.
(The vehicle side of control module may be damaged.) For
identification of trouble code, connect Tech2 to data link
connector.
Clear of trouble code memory
1. Clear the trouble code memory using F1: Clear DTC
Information for Tech2.
2. After more than 1 second has elapsed after the ignition key
has been turned ON, short between No. 11 and No. 4 or 5

TECH2 CONNECTION
The Tech2 scan tool is used to electrically diagnose the
automatic transmission system and to check the system. The
Tech2 enhances the diagnosis efficiency though all the
troubleshooting can be done without the Tech2.
The Tech2 is a portable, compact, and light tester. When it is
connected to the diagnosis connector of the vehicle, you can
perform a variety of diagnoses and tests by communicating
with the Transmission Control Module (TCM) of the vehicle.
1. Configuration of Tech2
1. Tech2 scan tool kit (No. 7000086), Tech2 scan tool (No.
7000057) and DLC cable (No. 3000095)
2. SAE16/19 adapter (No. 3000098) (1), RS232 loop back
connector (No. 3000112) (2), and PCMCIA card (No.
3000117) (3)
2. Tech2 Connection
•Observe the Tech2 User Guide.
1. Check the ignition is OFF.
2. Inser t the ISUZU 2000 system PCMCIA card (1) into the
Te c h 2 ( 4 ) .
3. Connect the SAE16/19 adapter (2) to the DLC cable (3).
4. Connect the DLC cable (3) to the Tech2 (4).
5. Connect the SAE16/19 adapter (2) to the diagnosis
connector of the vehicle.
6. Turn the ignition of the vehicle ON and press the "PWR"
key of the Tech2.
•Check the display of the Tech2.
NOTE:
Be sure to check that the power is not supplied to the
Tech2 when attaching or removing the PCMCIA card.

Once the test vehicle has been identified an “Application
(Power train) Menu" screen appears. Please select the
appropriate application.
The following table shows, which functions are used for
the available equipment versions.
Diagnostic Trouble Codes
The purpose of the “Diagnostic Trouble Codes" mode is
to display stored TCM trouble codes.
When “Diagnostic Trouble Codes" is selected an
“Application Menu" screen appears.
Clear DTC Information
The purpose of the “Clear DTC Information" mode is to
command the clearing of stored TCM trouble codes.
When “Clear DTC Information" is selected, a “Clear
DTC Information", warning screen appears. This screen
informs you that by cleaning DTC's, “all stored DTC
information in controller will be erased".
Do you want to clear DTC's (Yes/No).
Press either the Yes or No key when answering.
After clearing codes, confirm system operation by test
driving the vehicle.
Allow the vehicle to shift through all four forward gears in
a manner which attempts to repeat the failure condition.
NOTE: When the trouble has not been repaired and thetrouble code cannot be erased, check the vehicle again.
DTC Information
When “DTC Information" is selected, an “Application
Menu" appears with a list of DTC information function
keys addressing DTC specifics and their origins.
Function key selections may vary for particular vehicle
and/or system.
Data Display
The purpose of the “Data Display" mode is to
continuously monitor data parameters.
The current actual values of all impor tant sensors and
signals in the system are display through F1 mode.
When “Data Display" is selected an “Application Menu"
appears.
See “TRANSMISSION DATA" and “TCC DATA” on next
page.
Snapshot
When “Snapshot" is selected an “Application Menu"
appears.
When “Transmission Snapshot" application is selected
from the “Application Menu", a “Snapshot Menu"
appears, displaying several options. “Snapshot" options
may vary from one system to another.
“Snapshot" allows a recording of all vehicle parameters.
There parameters may then be replayed at a future
point in time.
This action allows you to focus on making the condition
occur, rather than trying to view all of the data in
anticipation of the fault. The snapshot will collect
parameter information around a trigger point that you
select.
When a snapshot is taken. It is recorded onto the
PCMCIA memory card. When the Tech2 is powered
down. Snapshots are not lost.

DTC P0710 (FLASHING CODE 16) OIL TEMPERATURE SENSOR FAILURE (OT2)
D07RY00021Circuit description:
The oil temperature sensor is a thermistor sensor that is
installed in the transmission case and converts
temperature changes into continuous electric signals,
then outputs them to the Transmission Control Module
(TCM). When the ATF temperature is low, the resistance
of the sensor (thermistor) goes up, so that the voltage of
the TCM signal becomes high.
As the ATF is gradually warmed, the resistance of the
sensor goes down and the voltage becomes low. At the
normal operating ATF temperature (80
C/176F) of the
transmission, the voltage of the TCM is about 3.7V.
Fail-safe condition:
The TCM controls fail-safe by detecting oil temperature
sensor failure.
Failure detection:
Short detection
• When the A/D value is detected less than 10
(220
C) for 5 minutes continuously while normal
judgment is not satisfied from ignition on.
Open detection
• After 15 minites passed when the engine revolution
is more than 400 rpm and the selector position
switch is selected on R, D, 2, L range.
• When the change of the A/D value from engine
star t is less than 15 and the minnum A/D value is
more than 1000 (-10
C) from engine star t.
Contents of control:
At failure detection
• Changes shift map to HOT2 map
• Controls as A/T oil temperature 200

• Lock-up control inhibit
• Up hill and down hill control inhibit
• Blinks "CHECK TRANS" lamp

Conditions of turning "CHECK TRANS" off:
Turns "CHECK TRANS" lamp off when judged 0km/h by
output revolution sensor after the normal area of oil
temperature 40
C – 150C is detected for 10 sec
continuously.
Reversion conditions from fail-safe:
Recovers at the same time as the conditions of turning
“CHECK TRANS” lamp off are satisfied.
Test description:
The following numbers correspond to circled numbers on
the diagnostic char t.
(1) Check that the voltage of the oil temperature sensor
varies with ATF temperatures.
(2) Check that the resistance of the oil temperature
sensor varies with ATF temperatures.
Diagnostic aids:
An intermittent may be caused by a poor connection,
rubbed through wire insulation or a wire broken inside
the insulation. Inspect related harness connector for
backed out terminals, improper mating, broken locks,
improperly formed or damaged terminals, poor terminal
to wire connection and damaged harness.

the TCM, which conver ts this sine wave signal (pulse
voltage) to a RPM signal.
Fail-safe control:
The TCM controls fail-safe by detecting input revolution
sensor failure.
Failure detection:
• When not even 1 pulse is input in the input revolution
sensor during the time 4 pulses are input in the
output revolution sensor.
