SELF DIAGNOSIS

Warning to the driver

・ When trouble has occurred to throttle position sensor,

vehicle speed sensor, or solenoid, “CHECK TRANS” lamp
is blinked (1.25 Hz) even during driving to warn the driver.

・ The trouble is recorded by trouble code is 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.

Indication Method:
(1) Terminals No.11 and No.4 or 5 (ground) of diagnosis

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 diagnosis connector.
Be careful shorting with a lead wire, etc.
(The vehicle side of control module may be damaged.)
For identification of trouble code, connect Tech 2 to
diagnosis connector.

Clear of trouble code memory
1. Clear the trouble code memory using F1: Clear DTC

Information for Tech 2.

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.

After erasing trouble code, check to see if the normal code is
outputted through running test.
