HYDRAULIC TEST
1. MEASURE LINE PRESSURE
NOTICE:
• Perform the test at the normal operating ATF
temperature: 50 to 80
C (122 to 176F).
• The line pressure test should always be
performed with at least 2 people. One person
should observe the condition of the wheels or
wheel chocks while the other is performing the
test.
• Be careful to prevent SST's hose from interfering
with the exhaust pipe.
• This test must be performed after checking and
adjusting the engine.
• Perform the test with the A/C OFF.
• When conducting the stall test, do not continue
for more than 10 seconds.
(a) Warm up the ATF.
(b) Remove the test plug on the transaxle case center
right side and connect SST.
SST 09992-00095 (09992-00231, 09992-00271)
(c) Fully apply the parking brake and chock the 4
wheels.
(d) Start the engine and check the idling speed.
(e) Keep your left foot firmly on the brake pedal and
move the shift lever to D.
(f) Measure the line pressure when the engine is idling.
Test Result Possible Cause
D range time lag exceeds standard value • Line pressure is low
• C1 clutch is worn
• F3 one-way clutch is not operating properly
• F4 one-way clutch is not operating properly
R range time lag exceeds standard value • Line pressure is low
• C3 clutch is worn
• B4 brake is worn
• F1 one-way clutch is not operating properly

(g) Depress the accelerator pedal as much as possible
with your right foot. Quickly read the highest line
pressure reading when the engine speed reaches
stall speed.
(h) Perform the measure line pressure test again with
the shift lever on R.

Problem Possible Cause
Measured values at all positions are higher than specified • Shift solenoid valve SLT defective
• Regulator valve defective
Measured values at all positions are lower than specified • Shift solenoid valve SLT defective
• Regulator valve defective
• Oil pump defective
• U/D (underdrive) direct clutch defective
Pressure is low when shift lever is on D only • D position circuit fluid leak
• Forward clutch defective
Pressure is low when shift lever is on R only • R position circuit fluid leak
• Direct clutch defective
• 1st and reverse brake defective

MANUAL SHIFTING TEST
1. MANUAL SHIFTING TEST
HINT:
• Through this test, it can be determined whether the
trouble occurs in the electrical circuit or if it is a
mechanical problem in the transaxle.
• If any abnormalities are found in the following test, the
problem is in the transaxle itself.
(a) Disconnect the connector of the transmission wire.
HINT:
It is possible to deactivate the electrical shift control
by disconnecting the transmission wire. The gear
positions can then be changed mechanically with
the shift lever.
(b) Drive with the transmission wire disconnected.
Move the shift lever to each position to check
whether the gear position changes as shown in the
table below.
(c) Connect the connector of the transmission wire.
(d) Clear the DTC (see page AX-29).

INITIALIZATION
1. RESET MEMORY
NOTICE:
• Perform the RESET MEMORY procedures (A/T
initialization) when replacing the automatic
transaxle assembly, engine assembly or ECM.
• RESET MEMORY can be performed only with the
intelligent tester.
HINT:
The ECM memorizes the vehicle conditions when the
ECT controls the automatic transaxle assembly and
engine assembly. Therefore, when the automatic
transaxle assembly, engine assembly, or ECM has been
replaced, it is necessary to reset the memory so that the
ECM can memorize the new information.
The reset procedures are as follows.
(a) Turn the ignition switch OFF.
(b) Connect the intelligent tester to the CAN VIM. Then
connect the CAN VIM to the DLC3.
(c) Turn the ignition switch ON and turn the tester ON.
(d) Enter the following menus: DIAGNOSIS /
ENHANCED OBD II.
(e) Perform the reset memory procedures from the
Engine menu.
CAUTION:
After performing the RESET MEMORY
procedures, be sure to perform the ROAD TEST
(see page AX-12) as described earlier.
HINT:
The ECM learns through the ROAD TEST.

MONITOR DRIVE PATTERN
1. TEST MONITOR DRIVE PATTERN FOR ECT
CAUTION:
Perform this drive pattern on a level surface and
strictly observe the posted speed limits and traffic
laws while driving.
HINT:
Performing this drive pattern is one method to simulate
the ECT's malfunction detection conditions.
The DTCs may not be detected through ordinary,
everyday driving. Also, DTCs may not be detected
through this drive pattern.
(a) Preparation for driving
(1) Warm up the engine sufficiently (engine coolant
temperature is 60
C (140F) or higher).
(2) Drive the vehicle when the atmospheric
temperature is -10
C (14F) or higher.
Malfunction is not detected when the
atmospheric temperature is less than -10
C
(14
F).
(b) Drive pattern
(1) Drive the vehicle through all the gears.
St o p
1st 2nd 3rd O/D O/D (lock-up
ON).
(2) Repeat the above drive pattern 3 times or more.
NOTICE:
• When using the intelligent tester, the
monitor status can be found in
"ENHANCED OBD II / DATA LIST" or under
"CARB OBD II".
• In the event that the drive pattern must be
interrupted (due to traffic conditions or
other factors), the drive pattern can be
resumed and, in most cases, the monitor
can be completed.
CAUTION:
Perform this drive pattern on a level road as
much as possible and strictly observe the
posted speed limits and traffic laws while
driving.

HINT:
*: Drive at such a speed in the uppermost gear to engage
lock-up. The vehicle can be driven at a speed lower than the
speed shown in the above diagram under the lock-up
condition.
NOTICE:
It is necessary to drive the vehicle for approximately 30
minutes to detect DTC P0711 (Transmission fluid
temperature sensor "A" performance).

PROBLEM SYMPTOMS TABLE
HINT:
• Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms
are listed in order of probability in the "Suspected area"
column of the table. Check each symptom by checking the
suspected areas in the order they are listed. Replace parts
as necessary.
• The Matrix Chart is divided into 2 chapters. When
troubleshooting, check Chapter 1 first. If instructions are
given in Chapter 1 to proceed to 2, proceed as instructed.
• If the instruction "Proceed to next circuit inspection shown
in problem symptoms table" is given in the flowchart for
each circuit, proceed to the next suspected area in the
table.
• If the problem still occurs even though there are no
malfunctions in any of the circuits, check the ECM and
replace it if necessary.
