TERMINALS AND REFERENCE VALUE MEASURED BETWEEN EACH TERMINAL
Diagnostic ProcedureECS004U6
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out the value of “TCC S/V DUTY” while driving.
Check the value changes according to driving speed.
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM connector and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.

OK or NG
OK >> GO TO 5.
NG >> GO TO 3.
3. CHECK HARNESS BETWEEN TCM AND TERMINAL CORD ASSEMBLY HARNESS CONNECTOR
1. Turn ignition switch OFF.
2. Disconnect terminal cord assembly harness connector and TCM connector.
3. Check continuity between terminal cord assembly harness con-
nector and TCM connector.
4. If OK, check harness for short to ground and short to power.
5. If OK, check continuity between ground and transaxle assembly.
6. Reinstall any part removed.
OK or NG
OK >> GO TO 4.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
4. CHECK VALVE RESISTANCE
1. Turn ignition switch OFF.
2. Disconnect terminal cord assembly connector in engine room.
3. Check resistance between terminal cord assembly harness con-
nector F23 terminal 5 (GY/R) and ground.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.
5. CHECK DTC
Perform AT- 3 6 8 , "
DTC Confirmation Procedure" .

1. Drain ATF through drain plug.
2. Remove torque converter.
3. Check torque converter one-way clutch using check tool as
shown in the right figure.
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.
