Eclipse V6-3.0L SOHC (2003)
Key Reminder Switch: Description and Operation
Forgotten Key Prevention Function
-
If the driver's door is open (door switch turned ON), when the key is inserted in the ignition switch (key reminder switch turned OFF), the
ETACS-ECU activates the door unlock relay for 0.25 seconds to prevent the door from being locked.
-
If you try to lock either the driver's or passenger's door when the passenger's door is open (door switch turned ON) and the key is inserted in the
ignition switch (key reminder switch turned OFF), the ETACS-ECU prevents the doors from being locked by activating the door unlock relay for
0.25 seconds.
GENERAL DESCRIPTION CONCERNING CENTRAL DOOR LOCKING SYSTEM
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 2.25 seconds every one second.
NOTE: The dotted line indicates that the system is trying to turn on the unlock relay if the door can not be unlocked.
