Pressing The Transmitter Unlock Button Twice
WARNING: This page is about a different car, the 2004 Mitsubishi Galant. However, it is still accessible from the selected car via links, so may be relevant.
When the transmitter unlock button 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. All the doors will be unlocked.
NOTE:
If the timed locking function is available, the doors will be locked in 30 seconds after the initial unlocking. Therefore, the second door unlocking should be done within 30 seconds after that initial unlocking.
