A sample of CONSULT-II display for DTC and 1st trip DTC is shown below. DTC or 1st trip DTC of a malfunc-
tion is displayed in SELF-DIAGNOSTIC RESULTS mode of CONSULT-II. Time data indicates how many times
the vehicle was driven after the last detection of a DTC.
If the DTC is being detected currently, the time data will be [0].
If a 1st trip DTC is stored in the ECM, the time data will be [1t].
FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA
The ECM records the driving conditions such as fuel system status, calculated load value, engine coolant tem-
perature, short term fuel trim, long term fuel trim, engine speed, vehicle speed, absolute throttle position, base
fuel schedule and intake air temperature at the moment a malfunction is detected.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data.
The data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II or
GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
details, see EC-109, "
CONSULT-II Function (ENGINE)".
Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-
lowing priorities to update the data.
For example, the EGR malfunction (Priority: 2) was detected and the freeze frame data was stored in the 2nd
trip. After that when the misfire (Priority: 1) is detected in another trip, the freeze frame data will be updated
from the EGR malfunction to the misfire. The 1st trip freeze frame data is updated each time a different mal-
function is detected. There is no priority for 1st trip freeze frame data. However, once freeze frame data is
stored in the ECM memory, 1st trip freeze data is no longer stored (because only one freeze frame data or 1st
trip freeze frame data can be stored in the ECM). If freeze frame data is stored in the ECM memory and freeze
frame data with the same priority occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Both 1st trip freeze frame data and freeze frame data (along with the DTCs) are cleared when the ECM mem-
ory is erased. Procedures for clearing the ECM memory are described in "EMISSION-RELATED DIAGNOS-
TIC INFORMATION ITEMS".
SYSTEM READINESS TEST (SRT) CODE
System Readiness Test (SRT) code is specified in Service $01 of SAE J1979.
As part of an enhanced emissions test for Inspection & Maintenance (I/M), certain states require the status of
SRT be used to indicate whether the ECM has completed self-diagnosis of major emission systems and com-
ponents. Completion must be verified in order for the emissions inspection to proceed.
If a vehicle is rejected for a State emissions inspection due to one or more SRT items indicating “INCMP”, use
the information in this Service Manual to set the SRT to “CMPLT”.
In most cases the ECM will automatically complete its self-diagnosis cycle during normal usage, and the SRT
status will indicate “CMPLT” for each application system. Once set as “CMPLT”, the SRT status remains
“CMPLT” until the self-diagnosis memory is erased.
Occasionally, certain portions of the self-diagnostic test may not be completed as a result of the customer's
normal driving pattern; the SRT will indicate “INCMP” for these items.

indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no
load.
6. Make sure that no DTC is displayed with CONSULT-II or GST.

PERIODIC MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. L = Lubricate.
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil (exc. LSD) at
every 30,000 miles (48,000 km) or 24 months, and change LSD gear oil every 15,000 miles (24,000 km) or 12 months.
(2) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, inspect CVT fluid deterioration with CON-
SULT-II every 60,000 miles (96,000 km), then change CVT fluid NS-2 if necessary. If CONSULT-II is not available, change (not just
inspect) CVT fluid NS-2 every 60,000 miles (96,000 km). Using transmission fluid other than Genuine NISSAN CVT Fluid NS-2 will
damage the CVT, which is not covered by the NISSAN new vehicle limited warranty.
(3) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.

3. Drain A/T fluid by removing the drain plug. Reinstall the drain plug to the specified torque.
CAUTION:
Do not reuse drain plug gasket.
4. Refill the transaxle with new specified A/T fluid through the A/T fluid charging pipe. Always refill the tran-
saxle with the same volume of A/T fluid that was drained out.
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to MA-22, "
Checking A/T Fluid" .
Balancing WheelsINFOID:0000000001704749

• Do not include the T-type spare tire when rotating tires.
CAUTION:
• When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
• Be careful not to tighten wheel nut at torque exceeding the
specification to prevent damage of disc rotor.

FUNCTION
The fresh air (A) and the recirculated air (B) drawn inside the pas-
senger compartment by the blower fan (1) is kept clean (C) on either
mode by the air conditioner filter (2), located before the evaporator
(3), in the A/C unit assembly.
REPLACEMENT TIMING
Replace the air conditioner filter according to the maintenance schedules. Refer to MA-6.
NOTE:
The air conditioner filter caution label is located inside the glove box door.
REPLACEMENT PROCEDURES
1. Remove the glove box assembly. Refer to IP-10.
2. Compress the air conditioner filter (1) downward while sliding it
to the RH side of the vehicle to release the upper pawl.
3. Move the bottom of air conditioner filter (1) upward as shown to
release the bottom tab, then remove it.
4. Replace the air conditioner filter with new one and install the new filter in the A/C unit assembly.
CAUTION:
Make sure that the air conditioner filter lower tab is fully seated, and that the air conditioner upper
pawl is locked into place securing the new filter into the A/C unit assembly.
5. Install the glove box assembly. Refer to IP-10
