Operating The Transmitter Unlock Switch Press Twice

When the transmitter unlock switch is pressed twice, the ETACS-ECU energizes its door unlock relay to operate the driver's door lock actuator and the other door lock actuators for 0.25 seconds each in succession. Then, the doors and the lift-gate will be unlocked.
