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.

DIAGNOSIS WITH TECH2
In this AW30-40LE transmission, troubleshooting can be
performed for electrical faults using the Tech2 scan tool.
If the CHECK TRANS lamp blinks, or if an electrical fault in the
transmission may probably exist, check trouble codes using the
Tech2 scan tool.
In the diagnostic procedures described in this manual, first
repair the faulty positions indicated by trouble code in the order
of numbers and then perform troubleshooting for the faulty
positions that are not indicated by trouble code. For correct
troubleshooting, it is necessary to first repair the trouble codes
of lower-order numbers, then to repair the trouble codes of
higher-order numbers in sequence.
How to Use This Manual:
Check trouble codes using the Tech2 scan tool.
If no codes are set:
•Refer to
F1: Data Display and identify the electrical faults
that are not indicated by trouble code.
If codes are set:
• Record all the codes displayed by the Tech2 and check if the
codes are intermittent (intermittent faults).
• Clear the codes.
• Drive the vehicle for a test to reproduce the faulty status.
• Check trouble codes again using the Tech2.
• If no code is displayed by test driving, the fault is intermittent.
In this case, refer to the cautions on intermittent conditions.
• If a code is present, refer to "DIAGNOSTIC TROUBLE
CODES (DTC) CHECK" for diagnosis.
• Because a code of high-order number may be set for the
reason that a code of low-order number has been set after
occurrence of a fault, perform repair work starting with a
lower-order number is ascending order.

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.

INTERMITTENT CONDITIONS
If the Tech2 displays a code as intermittent, or if after a
test drive a code does not reappear, the problem is most
likely a faulty electrical connection or loose wiring.
Terminals should always be the prime suspect.
Intermittent rarely occur in sophisticated electronic
components such as the Transmission Control Module
(TCM).
When an intermittent problem is encountered, check
suspect circuits for:
• Poor terminal to wire connection.
• Terminals not fully seated in the connector body
(backed out).
• Improperly formed or damaged terminals.
• Loose, dirty, or corroded ground connections.
HINT: Any time you have an intermittent in more than
one circuit, check whether the circuits share a
common ground connection.
• Pinched or damaged wires.
• Electro-Magnetic Interference (EMI)
HINT: Check that all wires are properly routed away
from spark plug wires, distributor wires, coil,
and generator. Also check for improperly
installed electrical options, such as lights, 2-
way radios, etc.
Use the F2: SNAPSHOT mode of the Tech2 to help
isolate the cause of an intermittent fault. The snapshot
mode will record information before and after the
problem occurs. Set the snapshot to "trigger" on the
suspect code (or codes) or, if you notice the repor ted
symptom during test drive, trigger the snapshot
manually.
After the snapshot has been triggered, command the
Tech2 to play back the flow of data recorded from each
of the various sensors. Signs of an intermittent fault in a
sensor circuit are a sudden unexplainable jump in data
values out of the normal range.
