^ to rear door lock actuator RH (door unlock sensor) terminal (3)
^ through body grounds (B54) and (B71).
Remote controller signal input
^ through window antenna
^ to multi-remote control unit terminal (21).
The multi-remote control system controls operation of the
^ power door lock
^ trunk lid opener
^ interior lamp
^ panic alarm
^ hazard lamp
^ ID code entry

OPERATED PROCEDURE
Power door lock operation
^ Key switch OFF signal (key not in cylinder)
^ Door switch CLOSE signal (all doors closed)
The two above signals are already input into multi-remote control unit. At this point, multi-remote control receives a LOCK signal from remote controller. Multi-remote control unit will then send a signal
^ from its terminal (16)
^ to door lock timer terminal (11).
Door lock timer now locks all doors.
With key switch in OFF position (key not in cylinder), multi-remote control unit receives an UNLOCK signal from remote controller. Multi-remote control unit will then send a signal
^ from its terminal (14)
^ to door lock timer terminal (8)
^ from multi-remote control unit terminal (20)
^ to theft warning control unit terminal (9).
Door lock timer now unlocks all doors and deactivates theft warning system.
Refer to "Power Door Lock" and "THEFT WARNING SYSTEM".

Trunk lid opener operation
With key switch in OFF position (key not in cylinder), multi-remote control unit receives an OPEN signal from remote controller. Ground is then supplied
^ to trunk lid opener actuator terminal (2)
^ from trunk lid opener cancel switch terminal (2).
With trunk lid opener cancel switch in ON position, a signal is sent
^ to trunk lid opener cancel switch terminal (1)
^ from multi-remote control unit terminal (2)
^ to multi-remote control unit terminal (3)
^ through body grounds (B9) and (B31).
When power and ground are provided, trunk lid opener actuator activates to open trunk lid. At this point, with signals door switch CLOSE (all doors closed) and door lock actuator (door unlock sensor) LOCK (all doors locked) inputted, an OPEN signal and a signal are sent
^ from multi-remote control unit terminal (20)
^ to theft warning control unit terminal (9)
^ from multi-remote control unit terminal (16)
^ to door lock timer terminal (11).
Theft warning system now deactivates.
Refer to "THEFT WARNING SYSTEM".

Interior lamp operation
Multi-remote control system turns interior lamp ON or OFF according to various inputs received.
Operating conditions
^ Key switch in OFF position (key not in cylinder)
^ Door switch in CLOSE position (all doors closed)
With interior lamp OFF under the above conditions, an ON signal is sent from remote controller.
^ Interior lamp then comes on for 30 seconds.
An ON or LOCK signal is sent from remote controller with interior lamp on.
^ Interior lamp will turn off.
An UNLOCK signal is sent from remote controller with interior lamp ON or OFF.
^ Interior lamp will turn on for 30 seconds.
For detailed description, refer to "Interior, Spot and Trunk Room Lamps".

Panic alarm operation
Multi-remote control system activates horn and headlamps intermittently under the following conditions:
^ Key switch OFF (key not in cylinder)
^ An alarm signal is sent from remote controller to multi-remote control system.
Ground is supplied intermittently
^ to horn relay terminal (2) and theft warning relay terminal (1)
^ through multi-remote control unit terminal (18).
Through this, horn and headlamps operate intermittently.
^ Panic alarm operates for 30 seconds.
^ When multi-remote control system receives any signal from remote controller during panic alarm operation, the alarm stops. However, the function indicated on remote controller will not be activated.

Hazard lamp operation
Multi-remote control system receives a LOCK signal from remote controller with the following signals already entered.
^ Key switch OFF signal (key not in cylinder)
^ Door switch CLOSE signal (all doors closed)
^ Door lock actuator (door unlock sensor) LOCK (all doors locked)
Multi-remote control system will then send a ground signal
^ to terminal (2) of the multi-remote control relay-1 and
^ to terminal (1) of the multi-remote control relay-2
^ through multi-remote control unit terminal (15).
Multi-remote control relay is now energized and hazard warning lamps flash.
