SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(1)A Supplemental Restraint System (SRS), which uses a driver-side air bag, has been installed in the 3668GT.(2)The SRS includes the following components: impact sensors, SRS diagnosis unit: SRS warning light, air bagmodule, clock spring, interconnecting wiring. Other SRS-related components (that may have to beremoved/installed in connection with SRS service or maintenance) are indicated in the table of contents byan asterisk (*).
WARNING!(1)Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead topersonal injury or death to service personnel (from inadvertent firing of the air bag) or to the driver (from
rendering the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.
(3) MlTSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B -Supplemental Restraint System (SRS), before beginning any service or maintenance of any component of the
ISRS or any SRS-related component.

AUTOMATIC TRANSAXLE - Troubleshootincl23-19Based upon use of the troubleshooting
Checks should be made of fluid levels and
the condition of the ATF, as well as the
condition of the manual control cables;
adjustments should then be made if found
to be necessary.
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 multi-use tester or voltmeter.
I
When the abnormal system is discovered,
check each element (sensors, etc.) one by
one, and make repairs as necessary.
IWhen the abnormal condition is presumed
to be in the oil-pressure-control system
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 oil-pressure pas-
sages for leakage, etc.
I
If the problem isunusually 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.
TROUBLESHOOTINGM23EEAYFunctional malfunctions of the ELC4A/T can lead to other
problems, such as those described below:(I
) 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 question
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.

Adjusting screw4
or~0\====m00~7/IIIITFAm
c-1
Pi(8) Tighten lock nut by hand until it contacts piston. Then, using
torque wrench, tighten to specification.
Lock nut: 29 Nm (21
ftlbs.)Caution
Use of socket wrench or torque wrench could result in
lock nut being turned with adjust rod.
(9) Remove the special tool to secure the piston and torque
plug to specification at L/R brake pressure take-up port.
LINE PRESSURE ADJUSTMENT
(I) Discharge AFT.
(2) Remove oil pan.
(3) Remove oil filter.
(4) Remove oil temperature sensor.
M23FSAC(5) Press solenoid valve harness grommet catch to push in
grommet; then, remove valve body assembly.
Caution
Do not let manual valve fall.
(6) Turn adjusting screw of regulator valve to obtain the
specified line pressure
(K/D brake pressure).
Standard value:870
- 890 kPa (124 - 127 psi)
Oil pressure change for
each turn of adjustment screw:38
kPa (54 psi)
(7)Check that an O-ring is fitted at the location shown on top off
valve body.
(8) Replace O-ring of solenoid valve intermediate grommet
with a new one and then fit the O-ring into case.6

Bolt B
= Length 25 mm (.984 in.)
Bolt C
= Length 40 mm (1.575 in.)
CautionSecure solenoid valve and oil temperature sensor
harness at locations shown.
(1O)lnstall oil filter.(1l)lnstall new oil pan gasket and oil pan.
(12)Add the specified amount of ATF.
(13)Carry out hydraulic test.
Readjust as necessary.
REDUCING PRESSURE ADJUSTMENTh323FfADWhen multi-use tester is not used
(1) Following the same steps as those in line pressure
adjustment, remove parts up to oil filter.
There is no need to remove valve body.
(2) Turn adjusting screw of lower valve body to obtain the
specified reducing pressure. Turn it counterclockwise to
increase the pressure.
Standard value:425 f 10 kPa (60 f 1 psi)
Oil pressure change for
each turn of adjusting screw:45 kPa (6 psi)(3) In the same way as in line pressure adjustment,
/nstall oil
filter and oil pan.
(4) Perform hydraulic test.
Adjust as necessary.
When multi-use tester is used
(1) Adjust to obtain the specified K/D brake pressure when PC
solenoid is energized at duty 50% with the multi-use tester.
Standard value:275 kPa (39 psi)
Oil pressure change for
each turn of adjusting screw:50 kPa (7 psi)(2) After adjustment has been made, check that the recuding
pressure is in the range 360
- 480 kPa (51 - 68 psi).
Caution
This adjustment should be made with oil temperature70
- 80°C (160 - 180°F).
The adjustment made with high oil temperature couldresult in improper adjustment due to a line pressure
drop at idle.
