SHIFT LOCK SYSTEM
System DescriptionINFOID:0000000003848940
The shift lever cannot be shifted from the “P” position unless the
brake pedal is depressed while the ignition switch is set to ON. The
shift lock is unlocked by turning the shift lock solenoid ON when the
ignition switch is set to ON, the park position switch is turned ON
(selector lever is in “P” position), and the stop lamp switch is turned
ON (brake pedal is depressed) as shown in the operation chart in the
figure. Therefore, the shift lock solenoid receives no ON signal and
the shift lock remains locked if all of the above conditions are not ful-
filled. (However, selector operation is allowed if the shift lock release
button is pressed.)
SHIFT LOCK OPERATION at “P” POSITION
When Brake Pedal Is Not Depressed (No Selector Operation Allowed)
The shift lock solenoid (A) is turned OFF (not energized) and the
solenoid rod (B) is extended with the spring when the brake pedal is
not depressed (no selector operation allowed) with the ignition
switch ON.
The connecting lock lever (C) is located at the position shown in the
figure when the solenoid rod is extended. It prevents the movement
of the detent rod (D). The selector lever cannot be shifted from the
“P” position for this reason.
When Brake Pedal Is Depressed (Shift Operation Allowed)
The shift lock solenoid (A) is turned ON (energized) when the brake
pedal is depressed with the ignition switch ON. The solenoid rod (B)
is compressed by the electromagnetic force. The connecting lock
lever (C) rotates when the solenoid is activated. Therefore, the
detent rod (D) can be moved. The selector lever can be shifted to
other positions for this reason.

< FUNCTION DIAGNOSIS >[CVT: RE0F09B]
SHIFT LOCK SYSTEM
The shift lock solenoid (A) is not energized when the ignition switch
is in any position other than ON. In this condition, the shift mecha-
nism is locked and “P” position is held. The operation cannot be per-
formed from “P” position if the brake pedal is depressed with the
ignition switch ON when the operation system of shift lock solenoid is
malfunctioning. However, the lock lever (B) is forcibly rotated and the
shift lock is released when the shift lock release button (C) is
pressed from above. Then the selector operation from “P” position
can be performed.
CAUTION:
Use the shift lock release button only when the selector lever cannot be operated even if the brake
pedal is depressed with the ignition switch ON.

P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000003848976
 The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the vehi-
cle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.
 Lock-up operation, however, is prohibited when CVT fluid temperature is too low.
 When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed shall not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
