With the ignition switch in the ACC or ON position, power is supplied:
^ from 7.5 A fuse (No. (10) located in the fuse block [HEC])
^ to smart entrance control unit terminal (17).
Terminal (10) of the smart entrance control unit is grounded through body grounds (M43), (M44) and (M60).

INPUTS
When the key switch is ON (ignition key is inserted in key cylinder), power is supplied:
^ through key switch terminal (2)
^ to smart entrance control unit terminal (24).
When any door switch is OPEN, ground is supplied:
^ to smart entrance control unit terminal (16)
^ through front door switch LH terminal (2), or
^ through any other door switch terminal (1).
When the front door lock actuator LH (door unlock sensor) is UNLOCKED, ground is supplied:
^ to smart entrance control unit terminal (12)
^ through front door lock actuator LH (door unlock sensor) terminal (4)
^ to front door lock actuator LH (door unlock sensor) terminal (2)
^ through body grounds (M43), (M44) and (M60).
When the front door lock actuator RH (door unlock sensor) is UNLOCKED, ground is supplied:
^ to smart entrance control unit terminal (13)
^ through front door lock actuator RH (door unlock sensor) terminal (4)
^ to front door lock actuator RH (door unlock sensor) terminal (2)
^ through body grounds (M43), (M44) and (M60).
When either rear door lock actuator (door unlock sensor) is UNLOCKED, ground is supplied:
^ to smart entrance control unit terminal ()
^ through either rear door lock actuator (door unlock sensor) terminal ()
^ to either rear door lock actuator (door unlock sensor) terminal ()
^ through body grounds (B14) and (B17).
Remote controller signal is input:
^ through window antenna
^ to smart entrance control unit terminal (37).
The multi-remote control system controls operation of the:
^ power door lock
^ interior lamp
^ panic alarm
^ hazard lamp
^ ID code entry.

OPERATING PROCEDURE
Power door lock operation

When the following input signals are both supplied:
^ key switch OFF (when ignition key is not inserted in key cylinder);
^ door switches CLOSED (when all the doors are closed); smart entrance control unit locks all the doors with input of LOCK signal from remote controller. When key switch is OFF (when ignition key is not inserted in key cylinder), smart entrance control unit unlocks the doors with input of UNLOCK signal from remote controller.

Interior lamp operation
When the following input signals are both supplied:
^ key switch OFF (when ignition key is not inserted in key cylinder);
^ door switches CLOSED (when all the doors are closed); multi-remote control system turns on interior lamp (for 30 seconds) with input of UNLOCK signal from remote controller.

Panic alarm operation
When key switch is OFF (when ignition key is not inserted in key cylinder), the multi-remote control system turns on and off horn and headlamps intermittently with the input of a PANIC ALARM signal from the remote controller.

Hazard lamp operation
When the following input signals are all supplied:
^ key switch OFF (when ignition key is not inserted in key cylinder);
^ door switches CLOSED (when all the doors are closed)
^ door lock actuator (door unlock sensor) LOCKED (when all the doors are locked); multi-remote control system outputs the following ground signals with input of LOCK signal from remote controller:
^ to multi-remote control relay-1 terminal (2)
^ to multi-remote control relay-2 terminal (2)
^ through smart entrance control unit terminal (7).
As a result, multi-remote control relay-1 and multi-remote control relay-2 are energized and hazard warning lamps flash on and off.
