- Troubleshooting
Based 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
1 found to be necessary
.
the condition of the manual control ca-
bles; adjustments should then be made if
If a presumption has been made that
there is an abnormal condition some-
where in the electronic-control system,
check the fault code, in order to determine
the probable location of the problem, by using a scan tool or voltmeter.
When the abnormal system is discovered,
check each element (sensors, etc.) one by
one, and make repairs as necessary.
When the abnormal condition is pre- sumed to be in the oil-pressure-control
When the result of the oil-pressure test does not satisfy the specified pressure,
1 passages for leakage, etc
.
check each system at places related to
the valve body, check the oil-pressure
If the problem is unusually dirty ATF,
abnormal noises, oil leakage, or slippage

condition of the transaxle Itself,

TROUBLESHOOTING
Functional malfunctions of the ELGWT 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 as
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
should
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.
