DTC P1740 LOCK-UP SELECT SOLENOID VALVE CIRCUIT
Revision: June 20062007 Versa
DTC P1740 LOCK-UP SELECT SOLENOID VALVE CIRCUITPFP:31941
DescriptionUCS00635

The lock-up select solenoid valve is included in the control valve assembly.

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.
CONSULT-II Reference ValueUCS00636
On Board Diagnosis LogicUCS00637

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P1740 LU-SLCT SOL/CIRC” with CONSULT-II is detected under the following
conditions.
–When TCM compares target value with monitor value and detects an irregularity.
Possible CauseUCS00638

Lock-up select solenoid valve

Harness or connectors
(Solenoid circuit is open or shorted.)
DTC Confirmation ProcedureUCS00639
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, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine and maintain the following conditions for at least 5
consecutive seconds.
RANGE: “D” position and “N” position
(At each time, wait for 5 seconds.)
4. If DTC is detected, go to CVT-160, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.

TCM terminal data are reference values, measured between each terminal and ground.
Diagnostic ProcedureUCS0063B
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Turn ignition switch ON.
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “TRANSMISSION” with CONSULT-II.
3. Read out the value of “LUSEL SOL OUT”.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between TCM connector terminal and ground.
3. Turn ignition switch OFF.
4. Disconnect the TCM connector.
5. Check if there is continuity between connector terminal and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
