CENTRAL DOOR LOCKING SYSTEM
The central door locking system operates the door lock actuator to lock or unlock the doors and liftgate using the door lock switch built into the front power window (main or sub RH) switch. The system has the following operations and features:
CENTRAL DOOR LOCKING OPERATION
The function that allows the driver's door to be opened by pulling the driver's door inside handle even when the driver's door inside lock knob is in the lock position is called "override function".
When the door is locked by the driver's or passenger's door lock switch, the ETACS-ECU operates its door lock relay and passes a current through the door lock actuators of all the doors (including the liftgate) for 0.25 second to lock all the doors (including the liftgate).
When the door is unlocked by the driver's or passenger's door lock switch, the ETACS-ECU operates its door unlock relay and passes a current through the door lock actuators of all the doors (including the liftgate) for 0.25 second to unlock all the doors (including the liftgate).
When the door is locked and unlocked by driver's or passenger's door lock switch consecutively, the ETACS-ECU operates its door lock relay and passes a current through the door lock actuators of all the doors (including the liftgate) for 0.25 second to lock all the doors (including the liftgate). Then, the ETACS-ECU operates its door unlock relay and passes a current through the door lock actuators of all the doors (including the liftgate) for 0.25 second to unlock all the doors (including the liftgate). Due to this, there may be a time lag between the driver's or passenger's door lock switch actuation and the time when all the doors (including the liftgate) are unlocked.
SELECTOR "P" POSITION-LINKED DOOR UNLOCKING FUNCTION
When the selector lever is shifted to the "P" (parking) position with the ignition switch turned ON, all the doors (including the liftgate) will be unlocked automatically, improving passengers' convenience for getting out. Using a customization function, the selector "P" position-linked door unlocking function can be switched.
When the selector lever is shifted to the P position with the ignition switch turned ON, the transaxle range switch "P" turns ON, ETACS-ECU turns the unlock relay output ON for 0.25 seconds to unlock all the doors (including the liftgate).
IGNITION SWITCH "LOCK (OFF)" POSITION-LINKED DOOR UNLOCKING FUNCTION
POWER WINDOWS
When the power window (main or sub) switch is operated, the door windows will open or close. This system has the following operations and features:
POWER WINDOW TIMER FUNCTION
Even after the ignition is switched off, the ETACS-ECU keeps the power window relay activated for approximately 30 seconds, enabling raising or lowering of the power windows by using the power window switches (timer function). After approximately 30 seconds, the power window relay is deactivated.
During this timer operation, if the driver's or front passenger's door is opened, the power window relay is deactivated from that moment.
