SELF-DIAGNOSIS

Warning to the driver

• When trouble has occurred to throttle position sensor, output

revolution sensor, input revolution sensor, neutral start
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 shorting 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
(ground) of data link connector. Then, after 1 second, but
within 6 seconds, discontinue shorting.

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.
