WARNING:
Do not remove radiator cap when the engine is
hot. Serious burns could occur from high-pressure
engine coolant escaping from radiator. Wrap a thick cl oth around the cap. Slowly turn it a quarter of a
turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

• 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-46, "
TCM Terminal and Reference Value".
• After performing each TROUBL E 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 br and of CVT fluid. Refer to MA-14, "
Flu-
ids 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 PrecautionINFOID:0000000005397764
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-15, "
CVT Fluid Cooler
Cleaning". For radiator replacement, refer to CO-40.
OBD-II SELF-DIAGNOSIS
• CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the malfunction indi cator lamp (MIL). Refer to the table on CVT-48, "
CONSULT-III
Function (TRANSMISSION)" for the indicator used to display each self-diagnostic result.
• The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memo- ries.
Always perform the procedure on CVT-27, "
OBD-II Diagnostic Trouble Code (DTC)" to complete the
repair and avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-541, "
Introduction".
• Certain systems and components, especially those re lated to OBD, may use the new style slide-lock-
ing type harness connector. For description and how to disconnect, refer to PG-66
.

FLUID CONDITION CHECK
Changing CVT FluidINFOID:0000000005397768
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 specified NISSAN CVT fluid in the CVT fluid
charging pipe with the engine running at idle speed.
CAUTION:
Only use the specifi ed NISSAN CVT fluid.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose [outlet side (1)]. NOTE:
About 30 to 50% extra fluid will be required for this procedure.
4. Check fluid level and condition. Refer to CVT-14, "
Checking CVT Fluid".
CAUTION:
Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid. Refer to CVT-48,
"CONSULT-III Function (TRANSMISSION)".
CVT Fluid Cooler CleaningINFOID:0000000005397769
Whenever a CVT is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can be trapped or become deposit in the CVT fluid cooler. This
debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.
In either case, malfunction of the newly serviced CVT may occur.
Debris, if present, may deposit as CVT fluid enters the cool er inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
CVT FLUID COOLER CLEANING PROCEDURE
1. Identify the CVT inlet and outlet fluid cooler hoses.
2. Position an oil pan under the inlet and outlet cooler hoses.
Fluid status Conceivable cause Required operation
Varnished (viscous
varnish state) Clutch, brake
scorchedReplace the CVT fluid and check the
CVT main unit and the vehicle for
malfunctions (wire harness, cooler
pipes, etc.)
Milky white or cloudy Water in the fluid Replace the CVT fluid and check for places where water is getting in.
Large amount of
metal powder mixed
in fluid Unusual wear of
sliding parts within
CVTReplace the CVT fluid and check for
improper operation of the CVT.
