WIRELESS DOOR LOCK CONTROL
SYSTEM OUTLINE
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 integration relay. 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
Slide door operation
The ignition key is inserted in to the ignition SW (Unlock warning SW on)
Ignition SW is on
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 keyless buzzer goes on twice.
With any door open, when the wireless door lock ECU receives a lock signal from the transmitter, the keyless buzzer goes
on for approx. 10 seconds. If the door is closed, or ignition SW is on, 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 front parking light is flashed once. During unlock operation, when the wireless door lock ECU receives an unlock
signal from the door unlock detection SW, the taillight and front parking light is flashed twice.
6. PANIC MODE FUNCTION
When the lock switch on the transmitter is kept pressed for approximately 2.5 sec., the wireless door lock ECU receives the
signal and enters the panic mode. The theft alarm goes on upon receiving the signal, and the headlights and taillights flash.
At this time, when any SW on the transmitter is pressed, the panic mode is cancelled, the theft alarm is stopped, and the
headlights and taillights go off.
7. REPEAT FUNCTION
If the lock 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.
8. POWER SLIDE DOOR FUNCTION
The power slide door can be opened/closed by operating the left power door SW or right power door SW on the transmitter.
