DTC P0744 A/T TCC S/V FUNCTION (LOCK-UP)

Description
This malfunction is detected when the A/T does not shift into 5th gear position or the torque converter clutch does not lock-up as instructed by the 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 Value

On Board Diagnosis Logic
This is an OBD-II self-diagnostic item.
Diagnostic trouble code "P0744 A/T TCC S/V FNCTN" with CONSULT-II is detected under the following conditions.
When A/T cannot perform lock-up even if electrical circuit is good.
When TCM detects as irregular by comparing difference value with slip rotation.
Possible Cause
Harness or connectors (The solenoid circuit is open or shorted.)
Torque converter clutch solenoid valve
Hydraulic control circuit
DTC Confirmation Procedure

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.
