Nissan X-Trail 32. Manual - part 2070

TM-238

< SYSTEM DESCRIPTION >

[CVT: RE0F10D]

COMPONENT PARTS

*: These components are included in control valve assembly.

CVT CONTROL SYSTEM : TCM

INFOID:0000000010622425

• The TCM consists of a microcomputer and connectors for signal

input and output and for power supply.

• The vehicle driving status is judged based on the signals from the

sensors, switches, and other control units, and the optimal tran-
saxle control is performed.

• For TCM control items, refer to 

TM-490, "CVT CONTROL SYS-

TEM : System Description"

.

CVT CONTROL SYSTEM : Transmission Range Switch

INFOID:0000000010622426

• The transmission range switch is installed to upper part of tran-

saxle case.

• The transmission range switch detects the selector lever position.

CVT CONTROL SYSTEM : Primary Speed Sensor

INFOID:0000000010622427

• The primary speed sensor is installed to side cover of transaxle.
• The primary speed sensor detects primary pulley speed.

• The primary speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM

judges the rotating body speed from the pulse signal.

CVT CONTROL SYSTEM : Output Speed Sensor

INFOID:0000000010622428

• The output speed sensor is installed to back side of transaxle.
• The output speed sensor detects final gear speed.

• The output speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM

judges the rotating body speed from the pulse signal.

CVT CONTROL SYSTEM : Input Speed Sensor

INFOID:0000000010622429

• The input speed sensor is installed to the front side of transaxle case.

- QR25DE models

• The input speed sensor detects input shaft speed. 
• The input speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM

judges the rotating body speed from the pulse signal.

CVT CONTROL SYSTEM : CVT Fluid Temperature Sensor

INFOID:0000000010622430

• The CVT fluid temperature sensor is installed to control valve.
• The CVT fluid temperature sensor detects CVT fluid temperature in oil pan.

• The fluid temperature sensor uses a thermistor, and changes the signal voltage by converting changes in the

CVT fluid temperature to a resistance value. TCM evaluates the CVT fluid temperature from the signal volt-
age value. 

CVT CONTROL SYSTEM : Primary Pressure Sensor

INFOID:0000000010622431

• The primary pressure sensor is installed to control valve.
• The primary pressure sensor detects the pressure applied to the primary pulley. 
• When pressure is applied to the ceramic device in the primary pressure sensor, the ceramic device is

deformed, resulting in voltage change. TCM evaluates the primary pressure from its voltage change. Voltage
is increased along with pressure increase. 

CVT CONTROL SYSTEM : Secondary Pressure Sensor

INFOID:0000000010622432

• The secondary pressure sensor is installed to control valve.
• The secondary pressure sensor detects the pressure applied to the secondary pulley.
