Precautions BCS001FT
NOTE:
If any malfunction occurs in the RE0F09A model transaxle, replace the entire transaxle assembly.
Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect the battery
cable from the negative terminal. Because battery voltage is
applied to TCM even if ignition switch is turned OFF.
When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are
not any bends or breaks on TCM pin terminal.
Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. Refer to CVT-40, "
TCM INSPECTION TABLE".
After performing each TROUBLE DIAGNOSIS, perform “DTC Confirmation Procedure”.
If the repair is completed the DTC should not be displayed in the “DTC Confirmation Procedure”.
Always use the specified brand of CVT fluid. Refer to MA-14, "Fluids and Lubricants" .
Use lint-free paper, not cloth rags, during work.
After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance,
etc.

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.

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.

TCM FunctionBCS001G2
The 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.
CONTROL SYSTEM OUTLINE
The CVT senses vehicle operating conditions through various sensors. It always controls the optimum shift
position and reduces shifting and lock-up shocks.
