Wireless Door Lock Control Without Smart Entry System

System Outline

Door lock control (Lock and unlock) and panic control (Theft alarm and flash) is performed by remote control, without the key inserted in the door key cylinder, using low-power electrical waves emitted from a transmitter.

1. Normal Operation

- Lock operation
When the lock SW on the transmitter is pressed, all the doors will lock.

- Unlock operation
When the unlock SW on the transmitter is pressed once, only the driver door will unlocks. When the unlock SW is pressed again within 3 seconds, all the doors will unlock.

2. Auto Lock Function
When the door is not actually opened within 30 seconds after the door has been unlocked by the unlock SW on the transmitter, all the doors will automatically lock. If any one of the following conditions is detected, the wireless door lock does not function.
- Any door is opened.
- The electrical key is inserted in the key slot.

4. Visual Confirmation of Lock or Unlock
During lock operation, when the body ECU receives a lock signal from the door lock detection SW, the turn signal light flashes once. During unlock operation, when the body ECU receives an unlock signal from the door lock detection SW, the turn signal light flashes twice.

5. Remote Panic Operation
Panic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once, interior lights light up, and theft alarm and horn sounds and turn signal lights, headlights and taillights flash. Then, any one of the button (Transmitter) is pushed once again, interior lights turn off, sounding and flashing will stop. Panic will not function when power SW is on.

6. Repeat Function
If the lock detection signal is not received in response to the output signal after the body ECU has output the lock signal, the lock signal is output again.

7. Illuminated Entry Function
When the body ECU detects the unlock state after the unlock operation has been made, it lights up the key slot, overhead J/B, power SW and interior light for approx. 15 sec. If all the doors are locked during this operation, lighting is cancelled and the lights immediately fade out.
