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".)
