Wireless Door Lock Control

In this system, the wireless door lock ECU receivers weak radio wave transmitted from the transmitter built-into the ignition key and outputs a signal to the instrument ECU. Accordingly, all the doors are can be locked and unlocked by remote control.

1. NORMAL OPERATION
* Lock operation
When the lock SW ON the transmitter is pressed, all the doors are locked.
* Unlock operation
When the unlock SW ON the transmitter is pressed once, only the driver door is unlocked. When the unlock SW is pressed again within 3 seconds, all the doors are unlocked.

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 are automatically locked. If any of the following conditions are detected, the wireless door lock does not function.
* Any door is opened.
* The ignition key is inserted into the ignition SW.

4. BUZZER SOUND FUNCTION
During lock operation, when the wireless door lock ECU receives a lock signal from the door unlock detection SW, the wireless door lock buzzer goes on once. During unlock operation, when the wireless door lock ECU receives an unlock signal from the door unlock detection SW, the wireless door lock buzzer goes on twice.

With any door open, when the wireless door lock ECU receives a lock signal from the transmitter the wireless door lock buzzer goes on for approx. 10 seconds. If the door is closed, or if the unlock signal is received from the transmitter while the buzzer is ON, the buzzer stops.

5. VISUAL CONFIRMATION OF LOCK OR UNLOCK
During lock operation, when the wireless door lock ECU receives a lock signal from the door unlock detection SW, the taillight and parking light is flashed once.

6. PANIC MODE FUNCTION
When the panic SW ON the transmitter is pressed, the wireless door lock ECU receives a signal and enters the panic mode. The signal input into the theft deterrent ECU from the wireless door lock ECU turns ON the theft deterrent horn and flashes the taillight and headlight. When the panic SW or the unlock SW of the transmitter is pressed during the panic mode, the panic mode is canceled and the theft deterrent horn stops and the taillight and headlight are turned OFF.

7. REPEAT FUNCTION
If the look detection signal in response to the output signal is not received after the wireless door lock ECU has output the lock signal, the lock signal is output again.
