SHIFT SOLENOID VALVE APFP:31940
DescriptionECS004TS
Shift solenoid valves A and B are turned “ON” or “OFF” by the TCM
in response to signals sent from the PNP switch, vehicle speed and
throttle position sensors. Gears will then be shifted to the optimum
position.

TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS004U4
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.

Diagnostic ProcedureECS004UA
1.CHECK TCM POWER SOURCE
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 10, 19, 28 and ground.
3. Turn ignition switch to “OFF” position.
4. Check voltage between TCM terminal 28 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check the following items:
●Harness for short or open between ignition switch and
TCM (Main harness)
●Ignition switch and fuse
Refer to PG-2, "
POWER SUPPLY ROUTING" .
2.CHECK A/T FLUID TEMPERATURE SENSOR WITH TERMINAL CORD ASSEMBLY
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminals 6 and 7 when A/T is cold.
4. Reinstall any part removed.
OK or NG
OK (With CONSULT-II)>>GO TO 3.
OK (Without CONSULT-II)>>GO TO 4.
NG >> 1. Remove oil pan.
2. Check the following items:
