Checking CVT FluidNLAT02431. Check for fluid leakage.

2. Check fluid level.
Fluid level should be check using ªHOTº range on A/T fluid
level gauge at fluid temperatures of 50 to 80ÉC (122 to 176ÉF)
after vehicle has been driven approximately 10 minutes in
urban areas after engine is warmed up. But it can be checked
at fluid temperatures of 30 to 50ÉC (86 to 122ÉF) using ªCOLDº
range on A/T fluid level gauge for reference after engine is
warmed up and before driving. However, fluid level must be
rechecked using ªHOTº range.
a. Park vehicle on level surface and set parking brake.
b. Start engine and then move selector lever through reach gear
range, ending in ªPº.
c. Check fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe it clean with lint-free
paper.
e. Re-insert A/T fluid level gauge into charging pipe as far as it
will go.
f. Remove A/T fluid level gauge and note reading. If level is at
low side of either range, add fluid through the speedometer
cable hole.
Use genuine NISSAN CVT fluid (NS-1) or exact equivalent.
CAUTION:
Do not overfill.
CAUTION:
SMA051D
Firmly fix the A/T fluid level gauge using a lip attached to the
fluid charging pipe.

3. Check fluid condition.
Check fluid for contamination. If fluid is very dark, smells
burned or contains frictional material check operation of CVT.
Refer to section AT for checking operation of CVT.
SMA294C
Changing CVT FluidNLAT02441. Warm up CVT fluid by driving the vehicle for 10 minutes.
2. Drain CVT fluid from radiator cooler hose (return side) and refill
with new CVT fluid at charging pipe with the engine running at
idle speed.
3. Refill until new CVT fluid comes out from radiator cooler hose
(return side).
About 30 to 50% extra fluid will be required for this procedure.
Fluid capacity
Hyper CVT: Approx. 8.1!(7-1/8 lmp qt)
Drain plug:
: 23 - 27 N´m (2.4 - 2.8 kg-m, 18 - 20 ft-lb)
CAUTION:
Use genuine NISSAN CVT fluid (NS-1) or exact equivalent.

HOW TO ERASE DTC (WITH GST)=NLAT0020S041. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªEURO-OBD SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-28. (The engine
warm-up step can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST). For details, refer to EC section ªGeneric Scan Tool (GST)º.
HOW TO ERASE DTC (NO TOOLS)NLAT0020S051. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Perform ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º. Refer to AT-28. (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Change the diagnostic test mode from Mode II to Mode I by turning the mode selector on the ECM.
Refer to EC section ªHOW TO SWITCH DIAGNOSTIC TEST MODESº.

Malfunction Indicator (MI)NLAT00211. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is for checking
the lamp.
+If the malfunction indicator lamp does not light up, refer to EL
section (ªWarning Lamps/System Descriptionº, ªWARNING
LAMPS AND CHIMEº).
(Or see MI & Data Link Connectors in EC section.)
2. When the engine is started, the malfunction indicator lamp
should go off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (EURO-OBD) malfunction. For
detail, refer to EC section (ªON BOARD DIAGNOSTIC SYS-
TEM DESCRIPTIONº).
CONSULT-IINLAT0022After performing ªSELF-DIAGNOSTIC PROCEDURE (WITH CON-
SULT-II)º (AT-22), place check marks for results on the ªDIAGNOS-
TIC WORKSHEETº, AT-43. Reference pages are provided follow-
ing the items.

If CVT is not displayed, check TCM power supply and ground
circuit. Refer to AT-58. If result is NG, refer to EL section
(ªPOWER SUPPLY ROUTINGº).

TCM Self-diagnostic Procedure (No Tools)=NLAT0022S0703Preparation
1. Turn ignition switch to ªOFFº position.
2. If throttle opener is equipped, connect the handy type vacuum
pump to the throttle opener and apply vacuum þ25.3 kPa
(þ253 mbar, þ190 mmHg, þ7.48 inHg). (If throttle opener is not
equipped, skip this step.)
3. Disconnect the throttle position switch harness connector.
4. Turn ignition switch to ªONº position.
5. Check continuity between terminals 4 and 5 of the closed
throttle position switch.
Continuity should exist.
(If continuity does not exist, check throttle opener and
closed throttle position switch. Then increase vacuum
until closed throttle position switch shows continuity.)
6. Connect the throttle position switch harness connector.
7. Warm up the engine.
8. Turn the ignition switch from ON to OFF two more times, and
then turn to OFF.
9. In the ªPº position of the selector lever, turn the ignition switch
ON, and verify that the CVT warning lamp turns on for about
2 seconds.
10. Turn the ignition switch OFF.
11. Press the brake pedal, and shift the selector lever to the ªDº
position.
12. Turn the ignition switch ON.
13. Release the brake, and shift the selector lever to the ªLº posi-
tion.
14. Fully depress both brake and accelerator pedals all the way to
the floor. Without releasing the brake and accelerator pedals,
shift the selector lever to the ªDº position.
15. Read the display from the SPORT indicator lamp to complete
the diagnosis.

IntroductionNLAT0023The TCM receives a signal from the vehicle speed sensor, throttle
position sensor or PNP switch and provides shift control or lock-up
control via step motor and CVT solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the EURO-OBD-related
parts of the CVT system for malfunction-diagnostic purposes. The
TCM is capable of diagnosing malfunctioning parts while the ECM
can store malfunctions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve
malfunction, etc.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this
case, careful checking of suspected circuits may help prevent the
replacement of good parts.
A visual check only, may not find the cause of the problems. A road
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the ªWork Flowº. Refer to AT-44.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such problems, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A ªDiagnostic Worksheetº like the
example (AT-43) should be used.
Start your diagnosis by looking for ªconventionalº problems first.
This will help troubleshoot driveability problems on an electronically
controlled engine vehicle.
Also check related Service bulletins for information.
