278Wireless Door Lock Control
In this system, the door control receiver receivers weak radio wave transmitted from the transmitter built-into the ignition key,
and outputs a signal to the body 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.
*When the unlock detection SW of all the doors are locked.
3. Wireless Door Lock Stop Function
If any of the following conditions are detected, the wireless door lock does not function.
Lock operation
*When any door is open (Door courtesy SW on)
*The ignition key is inserted into the ignition SW (Unlock warning SW on)
*Ignition SW is on
Unlock operation
*Ignition SW is on
4. Visual Confirmation of Lock or Unlock
During lock operation, when the door control receiver receives a lock signal from the door unlock detection SW, the turn
signal light is flashed once. During unlock operation, when the door control receiver receives an unlock signal from the door
unlock detection SW, the turn signal light is flashed twice.
5. Panic Mode Function
When the panic SW on the transmitter is pressed, the door control receiver receives a signal and enters the panic mode.
The signal input into the theft deterrent ECU from the body 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.
6. Repeat Function
If the lock detection signal in response to the output signal is not received after the door control receiver has output the lock
signal, the lock signal is output again.
