The SELF-DIAGNOSIS results will be as follows:
The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.
During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated.
EURO-OBD SELF-DIAGNOSISNLAT0004S04+CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the SPORT indicator lamp. Refer to the table on AT-22 for the indicator used to dis-
play each self-diagnostic result.
+The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure ªHOW TO ERASE DTCº on AT-19 to complete the repair and avoid
unnecessary blinking of the MI.
For details of EURO-OBD, refer to EC section (ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº).
+Certain systems and components, especially those related to EURO-OBD, may use a new style
slide-locking type harness connector.
For description and how to disconnect, refer to EL section, ªDescriptionº, ªHARNESS CONNEC-
TORº.

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.
4. Check fluid level and condition.
