DIAGNOSIS

BASIC TROUBLESHOOTING

AW30-40LE transmission, called Electronic Controlled Transmission (ECT), differs from oil pressure control type
transmissions in that it is controlled by a microcomputer. Accordingly, its troubleshooting procedure differs also.
Before troubleshooting an ECT, first determine whether the problem is electrical or mechanical. To do this, just refer to
the basic troubleshooting flowchart provided below. If the cause is already known, using the basic troubleshooting
chart below along with the general troubleshooting chart on the following page should speed the procedure.

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.
