TORQUE CONVERTER CLUTCH SOLENOID VALVE

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.
CONSULT-II Reference ValueECS00CSV
Remarks: Specification data are reference values.
On Board Diagnosis LogicECS00CSW
Possible CauseECS00CW8
Check the following items.

Torque converter clutch solenoid valve.

Harness or connector.
(The solenoid circuit is open or shorted.)
DTC Confirmation ProcedureECS00CSX
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and wait at
least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II and
wait at least 1 second.
3. Start engine and maintain the following condition for at least 5
consecutive seconds.
VHCL SPEED SE: 80 km/h (50 MPH) or more
THROTTLE POSI: 0.5/8 - 1.0/8
SLCT LVR POSI: D position
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
4. If the check result is NG, go to AT- 3 7 1 , "

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.
