5. Features
5.1 Door lock control
The RECEIVER sends “LOCK” signal to the door-lock actuators when LOCK button on the TRANSMITTER
is pressed. The RECEIVER also sends “UNLOCK” signal to the door-lock actuators when UNLOCK button
on the TRANSMITTER is pressed.
These functions don’t work if the key is in the key cylinder.
5.2 Automatic locking
The RECEIVER sends “LOCK” signal to the door-lock actuators if any of the doors are not opened within
30 seconds after UNLOCK button on the TRANSMITTER is pressed.
This function prevents the key from continuing the state of UNLOCK when the UNLOCK button is pressed
by accident, such as the key is in user’s pockets.
5.3Theft alarm(panic alarm)
The RECEIVER sends signal to the horn circuit and Front ECU when PANIC button on the TRANSMITTER.
Afterward the vehicle starts sounding the horn and flashing the headlight intermittently.
These functions continue for 175 seconds unless any of the buttons on the TRANSMITTER are pressed.
5.4 Battery saving
Because the power source of the receiver is the car battery, it is very important to minimize power
consumption. The RECEIVER (CPU: within RECEIVER) works intermittently to reduce the battery
exhaustion.
