< PRECAUTION >[CVT: RE0F10A]
PRECAUTIONS
Turn ignition switch OFF and disconnect negative battery
cable before connecting or disconnecting the TCM harness
connector. Because battery voltage is applied to TCM even if
ignition switch is turned OFF.
When connecting or disconnecting pin connectors into or
from TCM, do not damage pin terminals (bend or break).
Check that there are not any bends or breaks on TCM pin ter-
minal, when connecting pin connectors.
Perform TCM input/output signal inspection and check
whether TCM functions normally or not before replacing TCM.
Refer to TM-275, "
Reference Value".
Perform “DTC Confirmation Procedure” after performing each
TROUBLE DIAGNOSIS.
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, "
Flu-
ids and Lubricants".
 Use lint-free paper, not cloth rags, during work.
 Dispose of the waste oil using the methods prescribed by law, ordi-
nance, etc. after replacing the CVT fluid.
Service Notice or PrecautionINFOID:0000000003806500
OBD 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 Indicator (MI). Refer to the table on TM-204, "
CONSULT-III Function
(TRANSMISSION)" for the indicator used to display each self-diagnostic result.
 The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memories.
Always perform the procedure on TM-202, "
Diagnosis Description" to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD, refer to EC-102, "
Diagnosis Description".

 If CVT fluid contains frictional material (clutches, brakes, etc.),
replace radiator and flush cooler line using cleaning solvent and

CAUTION:
Replace O-ring with new ones at the final stage of the operation when installing.
1. Remove drain plug from oil pan.
2. Remove drain plug gasket from drain plug.
3. Install drain plug gasket to drain plug.
CAUTION:
Never reuse drain plug gasket.
4. Install drain plug to oil pan. Refer to TM-321, "
Exploded View".
5. Fill CVT fluid from CVT fluid charging pipe to the specified level.
CAUTION:
 Use only Genuine NISSAN CVT Fluid NS-2. Never 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.
 Sufficiently shake the container of CVT fluid before using.
 Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid.
6. With the engine warmed up, drive the vehicle in an urban area.
NOTE:
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).
7. Check CVT fluid level and condition.
8. Repeat steps 1 to 5 if CVT fluid has been contaminated.

OIL PAN
Inspection
INFOID:0000000003806526
Check foreign materials in oil pan to help determine causes of malfunction. If the CVT fluid is very dark, smells
burned, or contains foreign particles, frictional material (clutches) may need replacement. A tacky film that will
not wipe clean indicates varnish build up. Varnish can cause valves and clutches to stick and can inhibit pump
pressure.
INSPECTION AFTER INSTALLATION
Check for CVT fluid leakage and check CVT fluid level. Refer to TM-304, "Inspection".
