Checking CVT FluidNLAT02431. Check for fluid leakage.

2. Check fluid level.
Fluid level should be check using ªHOTº range on A/T fluid
level gauge at fluid temperatures of 50 to 80ÉC (122 to 176ÉF)
after vehicle has been driven approximately 10 minutes in
urban areas after engine is warmed up. But it can be checked
at fluid temperatures of 30 to 50ÉC (86 to 122ÉF) using ªCOLDº
range on A/T fluid level gauge for reference after engine is
warmed up and before driving. However, fluid level must be
rechecked using ªHOTº range.
a. Park vehicle on level surface and set parking brake.
b. Start engine and then move selector lever through reach gear
range, ending in ªPº.
c. Check fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe it clean with lint-free
paper.
e. Re-insert A/T fluid level gauge into charging pipe as far as it
will go.
f. Remove A/T fluid level gauge and note reading. If level is at
low side of either range, add fluid through the speedometer
cable hole.
Use genuine NISSAN CVT fluid (NS-1) or exact equivalent.
CAUTION:
Do not overfill.
CAUTION:
SMA051D
Firmly fix the A/T fluid level gauge using a lip attached to the
fluid charging pipe.

TCM FUNCTION=NLAT0014S03The function of the TCM is to:
+Receive input signals sent from various switches and sensors.
+Determine required line pressure, shifting point and lock-up operation.
+Send required output signals to the step motor and the respective solenoids.
INPUT/OUTPUT SIGNAL OF TCMNLAT0014S04
Switches, sensors and actuators Function
InputPNP switch Detects select lever position and sends a signal to TCM.
Throttle position sensor Detects throttle valve position and sends a signal to TCM.
Closed throttle position switch Detects throttle valve's fully-closed position and sends a signal to TCM.
Wide open throttle position switchDetects a throttle valve position of greater than 1/2 of full throttle and
sends a signal to TCM.
Engine speed signal From ECM.
CVT fluid temperature sensor Detects transmission fluid temperature and sends a signal to TCM.
CVT fluid pressure sensor Detects transmission fluid pressure and sends a signal to TCM.
Primary speed sensor Detects primary pulley rpm and sends a signal to TCM.
Secondary speed sensor Detects secondary pulley rpm and sends a signal to TCM.
Stop lamp switchSends a signal to the TCM relaying the operation condition of the brake
pedal.
SPORT mode switchSends a signal to the TCM relaying the operation condition of the SPORT
mode switch.
ABS control unit Sends a signal to the TCM operation condition of the ABS.
OutputStep motor Regulates pulley position in relation to a signal sent from TCM.
Line pressure solenoid valveRegulates (or decreases) line pressure suited to driving conditions in rela-
tion to a signal sent from TCM.
Torque converter clutch solenoid
valveRegulates (or decreases) lock-up pressure suited to driving conditions in
relation to a signal sent from TCM.
SPORT indicator lamp Shows the operation condition of the SPORT mode switch.

TCM Self-diagnostic Procedure (No Tools)=NLAT0022S0703Preparation
1. Turn ignition switch to ªOFFº position.
2. If throttle opener is equipped, connect the handy type vacuum
pump to the throttle opener and apply vacuum þ25.3 kPa
(þ253 mbar, þ190 mmHg, þ7.48 inHg). (If throttle opener is not
equipped, skip this step.)
3. Disconnect the throttle position switch harness connector.
4. Turn ignition switch to ªONº position.
5. Check continuity between terminals 4 and 5 of the closed
throttle position switch.
Continuity should exist.
(If continuity does not exist, check throttle opener and
closed throttle position switch. Then increase vacuum
until closed throttle position switch shows continuity.)
6. Connect the throttle position switch harness connector.
7. Warm up the engine.
8. Turn the ignition switch from ON to OFF two more times, and
then turn to OFF.
9. In the ªPº position of the selector lever, turn the ignition switch
ON, and verify that the CVT warning lamp turns on for about
2 seconds.
10. Turn the ignition switch OFF.
11. Press the brake pedal, and shift the selector lever to the ªDº
position.
12. Turn the ignition switch ON.
13. Release the brake, and shift the selector lever to the ªLº posi-
tion.
14. Fully depress both brake and accelerator pedals all the way to
the floor. Without releasing the brake and accelerator pedals,
shift the selector lever to the ªDº position.
15. Read the display from the SPORT indicator lamp to complete
the diagnosis.
