Wireless Door Lock Control
In this system, the wireless door lock ECU receivers weak radio wave transmitted from the transmitter 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
After all the doors are unlocked by pushing the UNLOCK SW of the transmitter, unless each of the doors is opened or the
ignition key is inserted, all the doors are locked again.
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
When doors are locked by using the transmitter, the hazard light flashes once. When doors are unlocked by using the
transmitter, the hazard light flashes twice. If UNLOCK SW of the transmitter is pushed while all the doors are locked, doors
are unlocked and the interior light and ignition key cylinder light are turned on simultaneously.
5. Panic Mode Function
When the panic SW on the transmitter is pressed, the panic mode is activated. The panic mode is canceled when the unlock
SW or panic SW is pressed.
6. 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.
