CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in “R” position.
Judgement Stall Test
O: Stall speed within standard value position.
H: Stall speed is higher than standard value.
L: Stall speed is lower than standard value.
LINE PRESSURE TEST
Line Pressure Test Port
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80°C
(122 to 176°F), then inspect the amount of CVT fluid and replenish if necessary.
NOTE:
The CVT fluid temperature rises in the range of 50 to 80°C (122 to 176°F) during 10 minutes of driv-
ing.
3. After warming up CVT, remove the oil pressure detection plug and install the oil pressure gauge. (Special
service tool: ST2505S001)
CAUTION:
When using the oil pressure gauge, be sure to use the O-ring attached to the oil pressure detec-
tion plug.
4. Securely engage the parking brake so that the tires do not turn.

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" .

8. Remove control device assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.

The knurled surface of rib should be upward when installing the
control cable to the control device assembly. And insert the con-
trol cable securely.

After installation is completed, adjust and check CVT position.
Refer to CVT-178, "
Adjustment of CVT Position" and CVT-179,
"Checking of CVT Position" .
Adjustment of CVT PositionBCS001MN
1. Place selector lever in “P” position.
2. Loosen control cable nut and place manual lever in “P” position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park
lock.
3. Hold the control cable at the end. Push and pull it twice or three
times, and then push it with a load of 9.8N (approximately 1 kg,
2.2 lb). Temporarily tighten the lock nut with the control cable
loose.
4. Connect control cable on manual lever.
CAUTION:
No application of a force to the manual lever.
5. Tighten control cable nut.
CAUTION:
Fix the manual lever when tightening.
