Power Locks: Description and Operation
CENTRAL DOOR LOCKING SYSTEMGENERAL DESCRIPTION CONCERNING THE CENTRAL DOOR LOCKING SYSTEM
The ECUs affect the functions and control of the central door locking system.
DOOR LOCK FUNCTION
OPERATING THE DRIVER'S OR FRONT PASSENGER'S DOOR LOCK KEY CYLINDER
When you insert the ignition key to the driver's or front passenger's door lock key cylinder and turn the key clockwise to lock the door, the ETACS-ECU energizes its door lock relay for 0.25 second to activate all the door lock actuators (including the liftgate). Then all the doors and the liftgate will be locked.
OPERATING THE DRIVER'S OR FRONT PASSENGER'S DOOR LOCK SWITCH
When the door is locked by driver's or front passenger's door lock switch, the ETACS-ECU energizes its door lock relay for 0.25 second to activate all the door lock actuators (including the liftgate). Then all the doors and the liftgate will be locked.
OPERATING THE DRIVER'S DOOR INSIDE LOCK KNOB
When the door is locked by driver's door inside lock knob, the ETACS-ECU energizes its door lock relay for 0.25 second to activate all the door lock actuators (including the liftgate). Then all the doors and the liftgate will be locked.
DOOR UNLOCK FUNCTION
OPERATING THE FRONT PASSENGER'S DOOR LOCK KEY CYLINDER
When you insert the ignition key to the front passenger's door lock key cylinder and turn the key counterclockwise to unlock the door, the ETACS-ECU energizes its door unlock relay for 0.25 second to activate all the door lock actuators (including the liftgate). Then all the doors and the liftgate will be unlocked.
OPERATING THE FRONT PASSENGER'S DOOR LOCK KEY CYLINDER
When you insert the ignition key to the front passenger's door lock key cylinder and turn the key counterclockwise to unlock the door, the ETACS-ECU energizes its door unlock relay for 0.25 second to activate all the door lock actuators (including the liftgate). Then all the doors and the liftgate will be unlocked.
OPERATING THE DRIVER'S OR FRONT PASSENGER'S DOOR LOCK SWITCH
When the door is unlocked by driver's or front passenger's door lock switch, the ETACS-ECU energizes its door unlock relay for 0.25 second to activate all the door lock actuators (including the liftgate). Then all the doors and the liftgate will be unlocked.
FORGOTTEN KEY PREVENTION FUNCTION
If the driver's door is opened with the ignition key inserted in the ignition key cylinder and then locked (i.e., the unlock switch integrated in the driver's door lock actuator is off, and the lock switch is on), the ETACS-ECU turns on the unlock relay for 0.25 second after approximately 0.3 second. This prevents the door from being locked unintentionally. If the system fails to unlock the door, the ETACS-ECU try to turn on the unlock relay five times in maximum for 0.25 second every one second.
