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
JSDIA3648GB

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
TM-88, "TRANSAXLE : Component Description"
• The line pressure solenoid valve uses the linear solenoid valve [N/
H (normal high) type].

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.

• Ignition switch: Other than ON
• Overdrive control switch is pressed when the OD OFF indicator lamp is ON.
• Selector lever is shifted to other than D position when the OD OFF indicator lamp is ON.
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.
LIGHTING CONDITION
Ignition switch: ON
SHUTOFF CONDITION
Ignition switch: Other than ON
