Troubleshooting
Line Pressure TestS7RS0B5104016
Purpose of this test is to check operat ing conditions of each part by measuring fluid pressure in fluid pressure line.
Line pressure test requires the following conditions.
• Automatic fluid is at normal operating temperature (70 – 80 °C / 158 – 176 °F).
• Fluid is replenished to proper level (between FULL and LOW on dipstick).
• Air conditioner switch is turned OFF.
1) Apply parking brake securely and place chocks against wheels.
2) Remove fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pr essure check hole in transaxle case.
Special tool
(A): 09925-37811-001
CAUTION!
After attaching oil pressure gauge, check that no fluid leakage exists.

4) Depress foot brake fully, run engine at idle and stall then check fluid pressure in “D” or “R” range.
CAUTION!
• Do not continue running engine at stall speed longer than 5 seconds.
• After performing line pressure test, be sure to leave engine running at idle for longer than one minute before performing another line pressure test.

DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine and warm it up to normal operating temperature.
4) Drive vehicle with 3rd or 4th gear in “D” range and slip c ontrolled lock-up ON for 20 seconds or longer referring to
“Automatic Gear Shift Table”.
5) Stop vehicle.
6) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting DTC detecting condition
Trouble area
The acceleration slip control function stops when the variation in the output
revolution speed of the specified amp litude and specified cycle is detected
within a specified period of time. When t he specified variation is not detected
after the acceleration slip control stops. • Mismatching ATF
• Torque converter clutch malfunction
• Valve body

Clutch Release Margin “C”1) Pull up parking brake fully and block wheels.
2) Start engine and keep engine at idle with neutral gear position.
3) Without clutch pedal (1) dep ressed, slightly push the
shift lever to re verse position until transaxle emits
gear contact noise. Do not shift the lever to reverse
position.
4) With emitting gear contact noise, be slow to depress clutch pedal (1), and at gear contact noise died
position (release point) stop depressing.
5) Measure distance between release point (4) and full stroke point (5) on clutch pedal (1) which is shown by
“C” in figure.
Clutch release margin
“C”: 25 – 55 mm (0.98 – 2.17 in.)
6) If “C” is not within specificat ion, it is possible that air
is trapped in this system. If suspected so, bleed air
referring to “Air Bleeding of Clutch System”. Upon
completion of above inspection, start engine and
check clutch for proper operation.
Clutch Fluid Level InspectionS7RS0B5306002
Refer to “Brake Fluid Level Inspection in Section 4A”.
Clutch fluid specification
: Refer to reservoir cap.
Air Bleeding of Clutch SystemS7RS0B5306003
CAUTION!
Brake fluid is extremely damaging to paint. If
fluid should accidentally touch painted
surface, immediately wipe fluid from paint
and clean painted surface.

Bleeding operation is necessary to remove air whenever
it entered hydraulic clutch system.
1) Fill master cylinder reservoir with brake fluid and keep at least one-half full of fluid during bleeding
operation.

Refer to reservoir cap
2) Remove bleeder plug cap from clutch operating cylinder (3). Attach a vinyl tube (1) to bleeder plug
(4), and insert the other end into container (2).
