P1740 LOCK-UP SELECT SOLENOID VALVE
DescriptionINFOID:0000000003849033
 The lock-up select solenoid valve controls lock-up clutch pressure or forward clutch pressure (reverse brake
pressure).
 When controlling lock-up clutch, the valve is turned OFF. When controlling forward clutch, it is turned ON.

DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “Data Monitor” mode for “TRANSMISSION”.
3. Start engine and maintain the following conditions for at least 5 consecutive seconds.
With GST
Follow the procedure “With CONSULT-III”.
Is
“P1740 LU-SLCT SOL/CIRC” detected?
YES >> Go to TM-94, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003849035
1.CHECK LOCK-UP SELECT SOLENOID VALVE CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check resistance between TCM vehicle side harness connector terminal and ground.
Is the inspection result normal?
YES >> GO TO 5.
NO >> GO TO 2.
2.CHECK HARNESS BETWEEN TCM AND CVT UNIT (LOCK-UP SELECT SOLENOID VALVE) (PART 1)
1. Disconnect CVT unit connector.
DTCItem
(CONSULT-III screen term)Malfunction is detected when... Possible cause
P1740 LU-SLCT SOL/CIRC Normal voltage is not applied to solenoid
due to cut line, short, etc.
 TCM detects as irregular by comparing
target value with monitor value. Harness or connectors
(Solenoid circuit is open or shorted.)

Wiring Diagram - CVT SHIFT LOCK SYSTEM -INFOID:0000000003862437
Component Function
Shift lock solenoidIt operates according to the signal from the stop lamp switch and
moves the lock lever.
Lock leverIt moves according to the operation of the shift lock solenoid and
performs the release of the shift lock.
Detent rodIt links with the selector button and restricts the selector lever
movement.
Park position switch It detects that the selector lever is in P position.
Shift lock release button It moves the lock lever forcibly.
