Checking CVT FluidBCS001FX
Fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F). The fluid level check pro-
cedure is as follows:
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20°C (68°F), it takes about 10
minutes for the CVT fluid to warm up to 50 to 80°C (122 to
176°F).
3. Park the vehicle on a level surface.
4. Apply parking brake firmly.
5. With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
6. Pull out the CVT fluid level gauge from the CVT fluid charging
pipe after pressing the tab on the CVT fluid level gauge to
release the lock.
7. Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid
level gauge rotating 180° from the originally installed position,
then securely push the CVT fluid level gauge until it meets the
top end of the CVT fluid charging pipe.
CAUTION:
When wiping away the CVT fluid level gauge, always use
lint-free paper, not a cloth rag.
8. Place the selector lever in “P” or “N” and make sure the fluid
level is within the specified range.
CAUTION:
When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until it is securely locked.

9. Check CVT fluid condition.
If CVT fluid is very dark or smells burned, check operation of
CVT. Flush cooling system after repair of CVT.
If CVT fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of CVT. Refer to CO-37,
"RADIATOR" .
Changing CVT FluidBCS001FY
1. Warm up CVT fluid by driving the vehicle for 10 minutes.
: Vehicle front
Radiator (2)
CVT fluid cooler hose [inlet side (3)]
Transaxle assembly (4)
2. Drain CVT fluid from CVT fluid cooler hose [outlet side (1)] and
refill with new CVT fluid at CVT fluid charging pipe with the
engine running at idle speed.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose
[outlet side (1)].
About 30 to 50% extra fluid will be required for this procedure.
CAUTION:
Use only Genuine NISSAN CVT Fluid NS-2. Do not mix with other fluid.
Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.
When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
Delete CVT fluid deterioration date with CONSULT-II after changing CVT fluid. Refer to CVT-46,
"Check CVT Fluid Deterioration Date" .
4. Check fluid leakage, fluid level and condition.

CVT
Step Motor
If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are
all turned OFF to hold the gear ratio used right before the non-standard condition occurred.
CVT Lock-up Select Solenoid
If an unexpected signal is sent from the solenoid to the TCM, the CVT lock-up select solenoid is turned OFF to
cancel the lock-up.
TCM Power Supply (Memory Back-up)
Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (for
controlling) from the battery is not supplied to TCM. Normal statues is restored when turning the ignition switch
OFF to ON after the normal power supply.
How to Perform Trouble Diagnosis for Quick and Accurate RepairBCS001GG
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, PNP
switch and provides shift control or lock-up control via CVT solenoid
valves.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused
by poor electric connections or improper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-II or a circuit tester connected should be performed.
Follow the CVT-26, "
WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSHEET” as
shown on the example (Refer to CVT-27
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.

CVT FLUID CHECK
Fluid Leakage and Fluid Level Check
Inspect for fluid leakage and check the fluid level. Refer to CVT-13, "Checking CVT Fluid" .
Fluid Condition Check
Inspect the fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80°C (122 to 176°F). Inspect the
amount of CVT fluid. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test.
It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D”
position.
6. While holding down the foot brake, gradually press down the
accelerator pedal.
7. Quickly read off the stall speed, and then quickly remove your
foot from the accelerator pedal.
CAUTION:
Do not hold down the accelerator pedal for more than 5 sec-
onds during this test.
8. Move the selector lever to the “N” position.
9. Cool down the CVT fluid.

Road TestBCS001GK
DESCRIPTION
The purpose of the test is to determine overall performance of
CVT and analyze causes of problems.
The road test consists of the following three parts:
1. “Check Before Engine Is Started” CVT-37
.
2. “Check at Idle” CVT-37
.
3. “Cruise Test” CVT-38
.
Before road test, familiarize yourself with all test procedures and
items to check.
Perform tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
CONSULT-II OPERATION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
Using CONSULT-II, perform a cruise test and record the result.
Print the result and ensure that shifts and lock-ups take place as per Shift Schedule.
1. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
2. Touch “MAIN SIGNALS” to set recording condition.
3. See “Numerical Display”, “Barchart Display” or “Line Graph Dis-
play”.
4. Touch “START”.
