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 the door switch LH is OPEN, ground is supplied:
^ to smart entrance control unit terminal (15)

When the door lock actuator RH (door unlock sensor) is UNLOCKED, ground is supplied to smart entrance control unit terminal (13) in the same manner as door lock actuator LH.
Remote controller signal input:
^ through internal antenna.
The multi-remote control system controls operation of the

^ panic alarm
^ hazard reminder.

OPERATION PROCEDURE

Power door lock operation
When the following input signals are both supplied:
^ key switch REMOVED (when ignition key is not inserted in key cylinder);
^ door switch CLOSED (when all the doors are closed).

The above two signals are already input into the smart entrance control unit. At this point, smart entrance control unit receives a LOCK signal from the remote controller. The smart entrance control unit locks all doors with input of the LOCK signal from the remote controller.
And then ground is supplied:
^ to multi-remote control relay terminal (1)
^ through smart entrance control unit terminal (7).

Multi-remote control relay is now energized, and the hazard warning lamps flash twice as a reminder-HAZARD REMINDER. For detailed description, refer to "TURN SIGNAL AND HAZARD WARNING LAMPS".

When an UNLOCK signal is sent from the remote controller once, the driver's door will be unlocked. Then, if an UNLOCK signal is sent from the remote controller again within 5 seconds, the passenger door will be unlocked.

To deactivate the horn chirp when using the remote controller, press both unlock and lock buttons for two seconds. With the horn deactivated, the exterior lights do not flash when the unlock button is pressed. To activate the horn chirp, press both unlock and lock buttons for two seconds.

Interior lamp operation
When the following input signals are both supplied:
^ key switch REMOVED (when ignition key is not inserted in key cylinder);
^ door switch 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.

For detailed description, refer to "INTERIOR ROOM LAMP".

Panic alarm operation
When key switch is OFF (when ignition key is not inserted in key cylinder), multi-remote control system turns on and off horn and headlamps intermittently with input of PANIC ALARM signal from remote controller. For detailed description, refer to "THEFT WARNING SYSTEM".

SMART ENTRANCE CONTROL UNIT
