Wireless Door Lock Control
Door lock control (Lock and unlock) and panic control (TVIP alarm and flash) is performed by remote control, without the
ignition key inserted in the door key cylinder, using low–power electrical waves emitted by a transmitter.
1. Wireless Door Lock or Unlock Normal Operation
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
when the lock or unlock button (Transmitter) is pushed, the door control receiver receives the electrical waves from the
transmitter, and sends a signal to the integration relay causing it to operate.
As a result, the integration relay judges whether the door is locked or unlocked based on the signal from the door lock motor
and door unlock detection SW, and sends a signal to switch the condition from lock to unlock or vice versa, causing the door
lock motor to operate.
2. Visual Confirmation of Lock or Unlock
If all doors indicate that they are locked after the lock command, parking lights and taillights will flash once. If any door
indicates that it is open after the unlock command, parking lights and taillights will flash twice.
3. Wireless Door Unlock Operation
Pushing the unlock button (Transmitter) once, driver’s door is unlocked. Furthermore, pushing the button again within 3
seconds, the other doors are unlocked.
4. Automatic Lock Operation
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
after pushing the button (Transmitter) to unlock all the doors, if a door is not opened within 30 seconds, all the doors will be
automatically relocked.
5. Wireless Control Stop Function
If a door is open (Door courtesy SW on), a signal is input from the door courtesy SW to the integration relay stopping
wireless door lock or unlock.
If the ignition key is in the ignition key cylinder (Unlock warning SW on), the unlock warning SW inputs a signal to the
integration relay stopping wireless door lock or unlock.
6. Repeat Function
In case an appropriate lock detection signal is not received after outputting a lock signal when pushing the lock button
(Transmitter), 1 seconds later, the integration relay output the lock signal again.
7. Remote Panic Operation
Panic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once,
theft alarm sounds and headlights and taillights flash. Then, the panic or the unlock button (Transmitter) is pushed once
more, sounding and flashing will stop. Panic will not function when ignition key is in ignition key cylinder.
