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
orI-pressure-controlsystem, check by making an oil-pressure
If the problem is unusually dirty ATF,
of the clutch or brakes, or an abnormal
condition of the transaxle itself,
disassem-TROUBLESHOOTING
”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.

OIL PRESSURE TESTS
1.

4.
5.Completely warm up the transaxle.
.”Raise the vehicle by using a jack so that the drive wheels
can be rotated.
Connect an engine tachometer and place it in a position
where it’s easy to see.
Attach the special oil-pressure gauge
(C-3292 or C-3293)and the adaptor
(MD998332) to each oil-pressure outlet
port.When the reverse pressure is to be tested, the 3,000
kPa(400 psi) type of gauge should be used.
Measure the oil pressure under various conditions , and
check to be sure that the measured results are within the
standard value range shown in the “Standard oil pressure
table” below.
If the oil pressure is not within the specified range, check
and repair as described in the section “Remedial steps if oilpressure is not normal” on the next page.
