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 3 and ground.
OK or NG
OK >> GO TO 2
NG >> 1. Remove control valve assembly. Refer to AT- 4 0 6 ,
"Control Valve Assembly and Accumulators" .
2. Check the following items:
Overrun clutch solenoid valve
Refer to AT-371, "
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 3 and TCM harness connector terminal 20.
If OK, check harness for short to ground and short to power.
4. Reinstall any part removed.

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.
