PRECAUTIONS
Revision: June 20062007 Versa
6. Turn the ignition switch ON.
CAUTION:
Do not start engine.
7. Select “SELF-DIAG RESULTS”.
8. Shift the selector lever to “R” position.
9. Depress slightly the accelerator pedal (Pedal angle: 2/8) while depressing the brake pedal.
10. Perform “ERASE”.
11. Shift the selector lever to “R” position after replacing TCM. Turn the ignition switch OFF.
12. Wait approximately 10 minutes after turning the ignition switch OFF.
13. Turn the ignition switch ON while shifting the selector lever to “R” position.
CAUTION:
Do not start engine.
14. Select “CALIBRATION DATA”.
15. Check that the value on “CALIBRATION DATA” is same as the data after erasing CVT-11, "
Calibration
Data" .

Restart the procedure from step 3 if the values are not same.
16. Shift the selector lever to “P” position.
17. Check that the shift position indicator in the combination meter turns ON (It indicates approximately 1 or 2
seconds after shifting the selector lever to “P” position.)

Check the following items if the shift position indicator does not turn ON. Repair or replace the shift
position indicator if necessary.
–The harness between TCM and ROM ASSY in the transaxle assembly is open or short.
–Cable disconnected, loosen, or bent from the connector housing.
–Power supply and ground of TCM. Refer to CVT-145, "DTC P1701 TRANSMISSION CONTROL MOD-
ULE (POWER SUPPLY)" .

Revision: June 20062007 Versa
Precautions UCS005XJ
NOTE:
If any malfunction occurs in the RE0F08A model transaxle, replace the entire transaxle assembly.

Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect negative
battery cable. 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. CVT-54, "
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-11,
"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.
Service Notice or PrecautionsUCS005XK
CVT FLUID COOLER SERVICE
If CVT fluid contains friction material (clutches, brakes, etc.), or if an CVT is replaced, inspect and clean the
CVT fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using cleaning solvent and
compressed air after repair. For CVT fluid cooler cleaning procedure, refer to CVT-18, "
CVT Fluid Cooler
Cleaning" . For radiator replacement, refer to CO-11, "RADIATOR" .

CVT FLUID
Revision: June 20062007 Versa
CVT FLUIDPFP:KLE50
Checking CVT FluidUCS005XN
FLUID LEVEL CHECK
Fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F).
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle to warm up the
CVT fluid. 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 and set the parking brake.
4. With engine at idle, while depressing brake pedal, move the
selector lever throughout the entire shift range and return it to
the “P” position.
5. Press the tab on the CVT fluid level gauge to release the lock
and pull out the CVT fluid level gauge from the CVT fluid charg-
ing pipe.
6. Wipe fluid off the CVT fluid level gauge. Then rotate the CVT
fluid level gauge 180° and re-insert it into the CVT charging pipe
as far as it will go.
CAUTION:
Always use lint free paper towels to wipe fluid off the CVT
fluid level gauge.
7. Remove the CVT fluid level gauge and check that the fluid level
is within the specified range as shown. If the fluid level is at or
below the low side of the range, add the necessary specified
NISSAN CVT fluid through the CVT charging pipe.
CAUTION:

Only use specified NISSAN CVT fluid.

Do not overfill the CVT.
8. Install the CVT fluid level gauge to the CVT fluid charging pipe until it locks.
CAUTION:
When CVT fluid level gauge is installed into the CVT fluid charging pipe, make sure that the CVT
fluid level gauge is securely locked in place.
