General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers dothem for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station,
including the spare, and adjust to the specified pressure if necessary. Check
carefully for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate
properly. Also ensure that all latches lock securely. Lubricate if necessary.
Make sure that the secondary latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other corrosive materials, check for
lubrication frequently.BT-7
BT-16
Tire rotationTires should be rotated every 10,000 km (6,000 miles). SU-7
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps,
and other lamps are all operating properly and installed securely. Also check

Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating prop-
erly.—
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play,
hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage.RS-4
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.
Item Reference page

DTC P0420 THREE WAY CATALYST FUNCTION
DTC P0420 THREE WAY CATALYST FUNCTION
PFP:20905
On Board Diagnosis LogicEBS00K8J
The ECM monitors the switching frequency ratio of heated oxygen
sensors 1 and 2.
A three way catalyst (Manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of heated oxygen sensors 1 and 2
approaches a specified limit value, the three way catalyst (Manifold)
malfunction is diagnosed.
DTC Confirmation ProcedureEBS00K8K
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
TESTING CONDITION:
●Open engine hood before conducting the following procedure.
●Do not hold engine speed for more than the specified minutes below.
1. Start engine and warm it up to the normal operating temperature.
2. Turn ignition switch ″OFF″ and wait at least 10 seconds.
3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least one minute under no
load.
4. Let engine idle for one minute.
5. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUP-
PORT” mode with CONSULT-II.
6. Rev engine up to 2,500 to 3,500 rpm and hold it for 3 consecu-
tive minutes then release the accelerator pedal completely.
If “INCMP” of “CATALYST” changed to “COMPLT”, go to step 9
7. Wait 5 seconds at idle.

DescriptionNJEL0583The Smart Entrance Control Unit is applied for QG engine models and YD engine models with common rail.
OUTLINENJEL0583S01The smart entrance control unit totally controls the following body electrical system operations.
Warning chime, refer to EL-136, “WARNING CHIME”.
Rear defogger and door mirror defogger, refer to EL-173, “REAR WINDOW DEFOGGER”.
Power door lock, refer to EL-261, “POWER DOOR LOCK SYSTEM”.
Power door lock - Super lock - (RHD models), refer to EL-301, “POWER DOOR LOCK — SUPER LOCK
—”.
Multi-remote control system, refer to EL-352, “MULTI-REMOTE CONTROL SYSTEM”.
NATS (Nissan Anti-Theft system), refer to EL-386, “NATS (NISSAN ANTI-THEFT SYSTEM)”.
Interior lamp, refer to EL-80, “INTERIOR ROOM LAMP”.
Also, smart entrance control unit has the “sleep/wake-up control” function. Smart entrance control unit puts
itself (the whole smart entrance control unit) to sleep under certain conditions to prevent unnecessary power
consumption. Then, when a certain input is detected, the system wakes itself up. For more detailed
information, refer to EL-368, “SLEEP/WAKE-UP CONTROL”.
INTERIOR LAMP/SPOT LAMP/VANITY MIRROR ILLUMINATIONNJEL0583S02The lamps turn off automatically when the interior lamp, spot lamp or/and vanity mirror illumination are illumi-
nated with the ignition key in the OFF position, if the lamp remains lit by the door switch open signal or if the
lamp switch is in the ON position for more than 30 minutes.
After lamps are turned off by the smart entrance control unit, the lamps illuminate again when:
Driver’s door is locked or unlocked with remote controller, door lock/unlock switch or door key cylinder.
Ignition switch is turned to ON.
Door is opened or closed,
Key is inserted into ignition key cylinder.
REAR WINDOW DEFOGGER/DOOR MIRROR DEFOGGERNJEL0583S03Rear window defogger is turned off in approximately 15 minutes after the rear window defogger switch is turned
on.
SLEEP/WAKE-UP CONTROLNJEL0583S04Sleep ControlNJEL0583S0401“Sleep” control prevents unnecessary power consumption. After the following conditions are met, the smart
entrance control unit suspends the operation. The whole smart entrance control unit is set in the “sleep” mode.
Ignition switch “OFF”
All electrical loads (in the smart entrance control unit) “OFF”
Timer “OFF”
Each switch do not input
Wake-up ControlNJEL0583S0402When the smart entrance control unit detects a “wake-up” signal, it wakes up the whole system and starts
operating again. When any one of the following switches are turned ON, the “sleep” mode is canceled:
Ignition switch
Hazard switch
Headlamp switch
Hood switch
Trunk room lamp switch (sedan models)
Back door switch (hatchback or wagon models)
