^ to multi-remote control unit terminal (4)
^ through body grounds (M101) and (M165).
When the front door lock actuator (Driver side) (door unlock sensor) is in UNLOCK position, ground is supplied
^ to multi-remote control unit terminal (10)
^ through front door lock actuator (Driver side) (door unlock sensor) terminal (4)
^ to front door lock actuator (Driver side) (door unlock sensor) terminal (2)
^ through body grounds (M1) and (M60).
When the front door lock actuator (Passenger side) (door unlock sensor) is in UNLOCK position, ground is supplied
^ to multi-remote control unit terminal (11)
^ through front door lock actuator (Passenger side) (door unlock sensor) terminal (4)
^ to front door lock actuator (Passenger side) (door unlock sensor) terminal (2)
^ through body grounds (M1) and (M60).
When the rear door lock actuator LH and/or RH (door unlock sensor) is in UNLOCK position, ground is supplied
^ to multi-remote control unit terminal (12)
^ through rear door lock actuator LH (door unlock sensor) terminal (4) and/or
^ through rear door lock actuator RH (door unlock sensor) terminal (4)
^ to rear door lock actuator LH (door unlock sensor) terminal (2) and/or
^ to rear door lock actuator RH (door unlock sensor) terminal (2)
^ through body grounds (M101) and (M165).
Remote controller signal input
^ through window antenna
^ to multi-remote control unit terminal (22).
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) and
^ to theft warning control unit terminal (7).
Door lock timer now locks all doors and activates theft warning system.
With key switch in OFF position (key not in cylinder), multi-remote control unit receives an UNLOCK signal from remote controller. Remote controller 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 (11).
Door lock timer now unlocks all doors and deactivates 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. Power is then supplied
^ from multi-remote control unit terminal (3)
^ to trunk lid opener cancel switch terminal (1).
With trunk lid opener cancel switch in ON position, a signal is sent
^ through trunk lid opener cancel switch terminal (2)
^ to trunk lid opener actuator terminal (1).
Ground is supplied
^ to trunk lid opener actuator terminal (3)
^ through body grounds (M1) and (M165).
Ground is also supplied
^ to multi-remote controller terminal (4)
^ through trunk room lamp switch terminal (1).
When power and ground are provided, trunk lid opener actuator activates to open trunk lid. Then a signal is sent
^ from multi-remote control unit terminal (20)
^ to theft warning control unit terminal (11).
Theft warning system now deactivates.
When trunk is closed, a signal is sent
^ from multi-remote control unit terminal (16)
^ to theft warning control unit terminal (7).
Theft warning system now activates again.

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 to 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.

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.

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 multi-remote control relay terminal (2)
^ through multi-remote control unit terminal (15).
Multi-remote control relay is now energized and hazard warning lamps flash
