Nissan Sentra. Manual - part 861

TM-80

< SYSTEM DESCRIPTION >

[CVT: RE0F11A]

COMPONENT PARTS

• The low brake solenoid valve uses the linear solenoid valve [N/L

(normal low) type].

NOTE:

• The principle of the linear solenoid valve utilizes the fact that the

force pressing on the valve spool installed inside the coil

increases nearly in proportion to the current. This allows it to pro-

duce a fluid pressure that is proportional to this pressing force.

• The N/L (normal low) type does not produce hydraulic control

when the coil is not energized.

CVT CONTROL SYSTEM : High Clutch & Reverse Brake Solenoid Valve

INFOID:0000000009759329

• The high clutch & reverse brake solenoid valve   is installed to

control valve.

• The high clutch & reverse brake solenoid valve adjusts the high

clutch and reverse brake engaging pressure.

• The high clutch & reverse brake solenoid valve uses the linear

solenoid valve [N/H (normal high) type].

NOTE:

• The principle of the linear solenoid valve utilizes the fact that the

force pressing on the valve spool installed inside the coil

increases nearly in proportion to the current. This allows it to pro-

duce a fluid pressure that is proportional to this pressing force.

• The N/H (normal high) produces hydraulic control when the coil

is not energized.

CVT CONTROL SYSTEM : Torque Converter Clutch Solenoid Valve

INFOID:0000000009759330

• The torque converter clutch solenoid valve   is installed to control

valve.

• The torque converter clutch solenoid valve controls the torque con-

verter clutch control valve. For information about the torque con-

verter clutch control valve, refer to

CVT CONTROL SYSTEM : Line Pressure Solenoid Valve

INFOID:0000000009759331

• The line pressure solenoid valve   is installed to control valve.

• The line pressure solenoid valve controls the pressure regulator

valve. For information about the pressure regulator valve, refer to

CVT CONTROL SYSTEM : G Sensor

INFOID:0000000009759332

• G sensor is installed to floor under instrument lower cover.

• G sensor detects front/rear G and inclination applied to the vehicle.

[CVT: RE0F11A]

COMPONENT PARTS

• G sensor converts front/rear G and inclination applied to the vehi-

cle to voltage signal. TCM evaluates front/rear G and inclination

angle of the vehicle from the voltage signal. 

CVT CONTROL SYSTEM : Overdrive Control Switch

INFOID:0000000009759333

• The overdrive control switch   is installed to the selector lever

knob.

• When the OD OFF indicator lamp on the combination meter is OFF

and the overdrive control switch is pressed, the OD OFF is active

and the OD OFF indicator lamp is ON.

• When the OD OFF indicator lamp on the combination meter is ON

and the overdrive control switch is pressed, the OD OFF is can-

celled and the OD OFF indicator lamp is OFF. 

CVT CONTROL SYSTEM : OD OFF Indicator Lamp

INFOID:0000000009759334

DESIGN/PURPOSE

The OD OFF indicator lamp notifies the driver that the shift control of

transaxle is in OD OFF.

BULB CHECK

For two seconds after the ignition switch is turned ON.

SIGNAL PATH

• When overdrive control switch signal is input to the combination meter, the combination meter transmits the

overdrive control switch signal to the TCM via CAN communication.

• When all of the following conditions are satisfied, the TCM transmits OD OFF indicator lamp signal to the

combination meter via CAN communication. The combination meter turns ON the OD OFF indicator lamp on

the combination meter, according to the signal.

- TCM receives overdrive control switch via CAN communication from combination meter.

- Selector lever: D position.

LIGHTING CONDITION

When all of the following conditions are satisfied.

• Ignition switch: ON

• Selector lever: D position

• Overdrive control switch is pressed when the OD OFF indicator lamp is OFF.

SHUTOFF CONDITION

When any of the conditions listed below is satisfied.

CVT CONTROL SYSTEM : Shift Position Indicator

INFOID:0000000009759335

PURPOSE

The shift position indicator displays the shift position of transaxle.

SIGNAL PATH

• The TCM judges the shift position by the transmission range switch signal.

• The TCM transmits the shift position signal to the combination meter via CAN communication. The combina-

tion meter shows the shift position indicator on the information display, according to the signal.
