Troubleshooting - Mitsubishi Stealth 1994 Import Service Manual

Based upon use of the troubleshooting
guide, the probable location of the problem
should be estimated.
Checks should be made of fluid levels and
the condition of the ATF, as well as the
adjustments should then be made if found
I
If a presumption has been made that there
is an abnormal condition somewhere in
the electronic-control system, check the
fault code, in order to determine the
probable location of the problem, by using
a 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 presumed
to be in the hydraulic-pressure-control sys-
When the result of the oil-pressure test
does not satisfy the specified pressure,
check each system at places related to the
valve body, check the hydraulic-pressure
passages for leakage, etc.
If the problem is unusually dirty ATF,
abnormal noises, oil leakage, or slippage of
the clutch or brakes, or an abnormal
condition of the transaxle itself, disassem-
ble and repair the transaxle.

p r o b l e m s , s u c h a s t h o s e d e s c r i b e d b e l o w :
(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 question
t h e u s e r c o n c e r n i n g t h e d e t a i l s o f t h e p r o b l e m , s u c h a s t h e
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
