TROUBLE DIAGNOSIS
Judgement Self-diagnosis Code
If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis
lIn order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.
lHowever, this information is erased by turning ignition switch OFF after executing self-diagnosis or by
erasing the memory using the CONSULT-II.

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
PFP:31940
DescriptionECS00FYE
lThe torque converter clutch solenoid valve is activated, with the gear in D5,22and 33by the TCM in
response to signals sent from the vehicle speed sensor and accelerator pedal position sensor. Torque
converter clutch piston operation will then be controlled.
lLock-up operation, however, is prohibited when A/T fluid temperature is too low.
lWhen the accelerator pedal is depressed (less than 1.0/8) 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 ValueECS00FYF
On Board Diagnosis LogicECS00FYG
Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-II or 3rd judgement flicker without
CONSULT-II is detected under the following conditions.
lWhen TCM detects an improper voltage drop when it tries to operate the solenoid valve.
lWhen TCM detects as irregular by comparing target value with monitor value.
Possible CauseECS00FYH
lTorque converter clutch solenoid valve
lHarness or connectors
(The solenoid circuit is open or shorted.)
DTC Confirmation ProcedureECS00FYI
CAUTION:
Always drive vehicle at a safe speed.
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 “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T”
with CONSULT-II.
3. Touch “START”.
4. Start engine.
5. Drive vehicle and maintain the following conditions for at least 5
consecutive seconds.
VHCL/S SE-A/T: 80 km/h (50 MPH) or more
ACCELE 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.
6. If DTC is detected go toAT- 111 , "
Diagnostic Procedure".
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle and maintain the following conditions for at least 5 consecutive seconds.
Vehicle speed: 80 km/h (50 MPH) or more
Accelerator opening: 0.5/8 - 1.0/8
Selector lever position: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
3. Perform self-diagnosis. Refer toAT-89, "
Diagnostic Procedure Without CONSULT-II".

DTC P0744 A/T TCC S/V FUNCTION (LOCK-UP)
DTC P0744 A/T TCC S/V FUNCTION (LOCK-UP)
PFP:31940
DescriptionECS00FYK
This malfunction is detected when A/T does not shift into 5th gear position or the torque converter clutch does
not lock-up as instructed by TCM. This is not only caused by electrical malfunction (circuits open or shorted)
but also by mechanical malfunction such as control valve sticking, improper solenoid valve operation, etc.
CONSULT-II Reference ValueECS00FYL
On Board Diagnosis LogicECS00FYM
Diagnostic trouble code “P0744 A/T TCC S/V FNCTN” with CONSULT-II or 3rd judgement flicker without
CONSULT-II is detected under the following conditions.
lWhen A/T cannot perform lock-up even if electrical circuit is good.
lWhen TCM detects as irregular by comparing difference value with slip rotation.
Possible CauseECS00FYN
lHarness or connectors
(The solenoid circuit is open or shorted.)
lTorque converter clutch solenoid valve
lHydraulic control circuit
DTC Confirmation ProcedureECS00FYO
CAUTION:
Always drive vehicle at a safe speed.
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. Start engine and Select “TCC S/V FNCTN CHECK” of “DTC
WORK SUPPORT” mode for “A/T” with CONSULT-II and touch
“START”.
2. Accelerate vehicle to more than 80 km/h (50 MPH) and maintain
the following condition continuously until “TESTING” has turned
to “COMPLETE”. (It will take approximately 30 seconds after
“TESTING” shows.)
ACCELE POSI: More than 1.0/8 (at all times during step 4)
TCC SOLENOID: 0.4 - 0.6 A
SLCT LVR POSI: “D” position
[Reference speed: Constant speed of more than 80 km/h (50
MPH)]
GEAR: “5” position
–For shift schedule, refer toAT-52, "Vehicle Speed at Which Lock-up Occurs/Releases".
–If “TESTING” does not appear on CONSULT-II for a long time, select “SELF-DIAG RESULTS”. In
case a DTC other than P0744 is shown, refer to applicable “TROUBLE DIAGNOSIS FOR DTC”.
3. Make sure that “OK” is displayed. (If “NG” is displayed, refer toAT- 11 3 , "
Diagnostic Procedure".)

Adjustment of A/T PositionECS00G2X
1. Loosen nut of control cable.
2. Place manual lever and selector lever in “P” position.
3. Push control cable in the direction shown with a force of 9.8 N
(1kg, 2.2 lb), release it. This is in the natural state, tighten nut to
the specified torque. Refer toAT- 2 1 0 , "
COMPONENTS".
Checking of A/T PositionECS00G2Y
1. Place selector lever in “P” position, and turn ignition switch ON (Do not start engine).
2. Check selector lever can be shifted to other than “P” position when brake pedal is depressed. Also check
selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Check selector lever stops at each position with the feel of engagement when it is moved through all the
positions. Check whether or not the actual position selector lever is in matches the position shown by the
shift position indicator and the A/T body.
5. The method of operating the selector lever to individual posi-
tions correctly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Check back-up lamps illuminate only when selector lever is
placed in the “R” position. Check back-up lamps does not illumi-
nate when selector lever is pushed against “R” position in the
“P” or “N” position.
8. Check engine can only be started with selector lever in the “P”
and “N” positions.
9. Check A/T is locked completely in “P” position.
