DescriptionECS007S8
The torque converter clutch solenoid valve is activated, with the gear
in “D
4 ”, by the TCM in response to signals sent from the vehicle
speed and throttle position sensors. Lock-up piston operation will
then be controlled.
Lock-up operation, however, is prohibited when A/T fluid tempera-
ture is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up
condition, the engine speed should not change abruptly. If there is a
big jump in engine speed, there is no lock-up.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle in D
1→ D2→ D3→ D4→ D4 lock-up position.
4. If DTC is detected, go to AT- 3 7 5 , "
Diagnostic Procedure" .
Without CONSULT-II
1. Start engine.
2. Drive vehicle in D
1→ D2→ D3→ D4→ D4 lock-up position.
3. Perform self-diagnosis.
Refer to AT-250, "
Diagnostic Procedure Without CONSULT-II" .
4. If DTC is detected, go to AT- 3 7 5 , "
Diagnostic Procedure" .

Diagnostic ProcedureECS007SA
1.CHECK VALVE RESISTANCE
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminal 5 and ground.
OK or NG
OK >> GO TO 2
NG >> 1. Remove oil pan. Refer to AT- 4 0 6 , "
Control Valve
Assembly and Accumulators" .
2. Check the following items:
Torque converter clutch solenoid valve
Refer to AT- 3 7 5 , "
Component Inspection" .
Harness of terminal cord assembly for short or open
2.CHECK POWER SOURCE CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check continuity between terminal 5 and TCM harness connector terminal 3.
If OK, check harness for short to ground and short to power.
4. Reinstall any part removed.
OK or NG
OK >> GO TO 3
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
3.CHECK DTC
Perform AT- 3 7 3 , "
SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

1. Drain ATF through drain plug.
2. Remove torque converter.
3. Check torque converter one-way clutch using check tool as
shown at right.
a. Insert check tool into the groove of bearing support built into
one-way clutch outer race.
b. When fixing bearing support with check tool, rotate one-way
clutch spline using screwdriver.
c. Check that inner race rotates clockwise only. If not, replace
torque converter assembly.

4. Remove A/T fluid charging pipe and fluid cooler tube.
5. Set manual shaft to position P.
6. Remove park/neutral position (PNP) switch.
7. Remove oil pan and oil pan gasket.
●Do not reuse oil pan bolts.
8. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
●If frictional material is detected, replace radiator after
repair of A/T. Refer to LC-16, "RADIATOR".
9. Remove control valve assembly according to the following pro-
cedures.
a. Remove control valve assembly mounting bolts A, B and C.
