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.

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)
