Diagnostic ProcedureBCS001JU
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis check. Refer to CVT-47, "
SELF-DIAGNOSTIC RESULT MODE" .
Is any malfunction of the
“U1000 CAN COMM CIRCUIT” indicated?
YES >> Check CAN communication line. Refer to CVT-53, "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK MANUAL MODE SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
3. Read out ON/OFF switching action of the “MMODE”, “NON M-
MODE”, “UPLVR”, “DOWNLVR”.
Without CONSULT-II
Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the
position mutually coincide when the selector lever is shifted to the “+ (up)” or “- (down)” side (1st ⇔ 6th gear).
OK or NG
OK >> GO TO 7.
NG >> GO TO 3.
3. CHECK MANUAL MODE SWITCH
Check manual mode switch. Refer to CVT-117, "
Component Inspection" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK SELF-DIAGNOSTIC RESULTS (UNIFIED METER AND A/C AMP)
Perform self-diagnosis check. Refer to DI-29, "
CONSULT-II Function (METER A/C AMP)" .
Is any malfunction detected by self-diagnosis?
YES >> Check the malfunctioning system.
NO >> GO TO 5.

DTC P1740 LOCK-UP SELECT SOLENOID VALVE CIRCUITPFP:31941
DescriptionBCS001LF

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 ValueBCS001LG
On Board Diagnosis LogicBCS001LH
Diagnostic trouble code “P1740 LU-SLCT SOL/CIRC” with CONSULT-II is detected under the following condi-
tions.

When TCM compares target value with monitor value and detects an irregularity.
Possible CauseBCS001LI

Lock-up select solenoid valve

Harness or connectors
(Solenoid circuit is open or shorted.)
DTC Confirmation ProcedureBCS001LJ
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-149, "
Diagnostic Procedure" .
