DescriptionECS007S4
The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the inhibitor switch, overdrive control
switch, vehicle speed and throttle position sensors. The overrun
clutch operation will then be controlled.

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 under the following conditions:
Selector lever in “D” position, overdrive control switch in “OFF”
position and vehicle speed higher than 10 km/h (6 MPH).
4. If DTC is detected, go to AT- 3 7 0 , "
Diagnostic Procedure" .
Without CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in “D” position, overdrive control switch in “OFF”
position and vehicle speed higher than 10 km/h (6 MPH).
3. Perform self-diagnosis.

TORQUE CONVERTER CLUTCH SOLENOID VALVE
TORQUE CONVERTER CLUTCH SOLENOID VALVE
PFP:31940
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.
