AUTOMATIC TRANSAXLE - TroubleshootingBased upon use of the troubleshooting
guide, the probable location of the prob-
lem should be estimated.
Checks should be made of fluid levels
and the condition of the ATF, as well as
bles; adjustments should then be made if
If a presumption has been made that
there is an abnormal condition some-
check the fault code, in order to determinethe probable location of the problem, by
When the abnormal system is discovered,
check each element (sensors, etc.) one byone, and make repairs as necessary.
“~^II_When the abnormal condition is pre-
sumed to be in the

”N21EeAYFunctional malfunctions of the ELC4A/T can lead to other
problems, such as those described below:
(1) Improper maintenance and/or adjustments
(2) Malfunctions of the electronic control functions
(3) Malfunctions of mechanical functions
(4) Malfunctions of hydraulic control functions
(5) Malfunctions of engine performance
etc.In order to properly determine (“Troubleshoot”) the source of
these malfunctions, it is first essential to methodically ques-
tion the user concerning the details of the problem, such qs
the condition of the problem, the situation at the time the
problem occurred, and any other relevant information, all in as
much detail as possible. The user
shoutd also be asked
whether or not the problem has occurred more than once,
and under what conditions.
Subsequently, certain tests should be conducted in a certain
order, as described at the left.
