< PRECAUTION >[CVT: RE0F09B]
PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003897196
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for On Board Diagnosis (OBD) System of CVT and EngineINFOID:0000000003849068
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
 Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid
valves, etc. will cause the MI to light up.
 Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to an open circuit. (Be sure the connector is free from water, grease, dirt,
bent terminals, etc.)
 Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MI to light up due to a short circuit.
 Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to a malfunction of the EVAP system or fuel injection system, etc.
 Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precaution for TCM and CVT Assembly ReplacementINFOID:0000000003849069
CAUTION:
 Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-III, and then turn ignition switch OFF.)
 When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.

Replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state. (CVT assembly must be replaced
first.)
Not replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state.
Replaced Not replaced RequiredRequired because data has been written in the EE-
PROM in the TCM and because the TCM cannot write
data from the ROM assembly in the transmission.

< PRECAUTION >[CVT: RE0F09B]
PRECAUTIONS
Precaution
INFOID:0000000003849071
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.
TM-111, "
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:0000000003849072
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-37, "
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.

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, brakes, etc.),
replace radiator and flush cooler line using cleaning solvent and
compressed air after repair of CVT. Refer to CO-13, "
Exploded
View".
ChangingINFOID:0000000003849077
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.
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. Refer to TM-37,
"CONSULT-III Function (TRANSMISSION)".
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.

check that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Check that selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check that the actual position of selector lever matches the position shown by shift position
indicator and manual lever on the transaxle.
5. The method of operating selector lever to individual positions
correctly should be as shown.

when the selector lever is pushed toward the “P” position.
CAUTION:
Check the lighting without pressing shift button.
9. Check that back-up lamps do not illuminate when selector lever is pushed toward the “R” position when in
the “P” or “N” position.
CAUTION:
Check the lighting without pressing shift button.
10. Check that the engine can only be started with selector lever in the “P” and “N” positions.
11. Check that transaxle is locked completely in “P” position.
ADJUSTMENT
