Keyless Entry: Description and Operation
MULTI-REMOTE CONTROL SYSTEMINPUTS
Power is supplied at all times
^ to key switch terminal 1
^ through 10 A fuse [No.24, located in the fuse block (J/B)].
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 32.
When the front door switch (driver side) is OPEN, ground is supplied
^ to smart entrance control unit terminal 29
^ through front door switch (driver side) terminal 2
^ to front door switch (driver side) terminal 3
^ through body grounds B7 and B24.
When the front door switch (passenger side) is OPEN, ground is supplied
^ to smart entrance control unit terminal 40
^ through front door switch (passenger side) terminal 1
^ through the front door switch RH case ground.
When the each door switch is OPEN, ground is supplied
^ to smart entrance control unit terminal 28
^ through each door switch case ground.
When the front door lock actuator (driver side) (door unlock sensor) is UNLOCKED, ground is supplied
^ to smart entrance control unit terminal 36
^ through door lock actuator (driver side) (door unlock sensor) terminal 4
^ to door lock actuator (driver side) (door unlock sensor) terminal 2
^ through body grounds M15, M71 and M76.
When the front door lock actuator (passenger side) (door unlock sensor) is UNLOCKED, ground is supplied to smart entrance control unit terminal 37 in the same manner as front door lock actuator (driver side).
When the rear door lock actuator LH or RH (door unlock sensor) is UNLOCKED, ground is supplied to smart entrance control unit terminal 26 in the same manner as other door lock actuator.
Remote controller signal is inputted to smart entrance control unit (the antenna of the system is combined with smart entrance control unit).
Then smart entrance control unit supplies power and ground to each door lock actuator.
The multi-remote control system controls operation of the
^ power door lock
^ interior lamp
^ panic alarm
^ hazard reminder
OPERATED 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 switch CLOSED (when all the doors are closed);
The two above signals are already input into smart entrance control unit. At this point, smart entrance control unit receives a LOCK signal from remote controller. Smart entrance control unit locks all doors with input of LOCK signal from remote controller.
When an UNLOCK signal is sent from remote controller once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from remote controller again within 5 seconds, all other door will be unlocked.
Hazard Reminder
Power is supplied at all times
^ to multi-remote control relay terminals 1, 3 and 6
^ through 10 A fuse [No.20, located in the fuse block (J/B)].
When smart entrance control unit receives a LOCK signal from remote controller, ground is supplied
^ to multi-remote control relay terminal 2
^ through smart entrance control unit terminal 7.
Multi-remote control relay is now energized, and hazard warning lamp flash twice as a reminder.
Interior Lamp Operation
When the following input signals are both supplied:
^ key switch OFF (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.
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 headlamp intermittently with input of PANIC ALARM signal from remote controller.
