ENGINE HOOD / DOOR: BACK DOOR CLOSER SYSTEM: SYSTEM DESCRIPTION

SYSTEM DESCRIPTION

1. The back door closer system releases/closes the latch of the back door lock using a motor.
(a) The back door closer system is used in the RX400h with the power back door system.
(b) Operating any power back door switch when the back door is fully closed inputs a request signal to the power back door ECU. The power back door ECU then outputs a "latch release" command to the back door lock in response to the input.
(c) The latch can be released only when the back door is unlocked.
(d) 4 switches are built into the back door lock, and the power back door ECU monitors each switch status. The power back door ECU controls latch "release/close" operations in response to the inputs from each switch.






(e) When any battery, fuse or the back door lock has been removed/installed, the back door lock is in the "lock" status. Therefore, it is necessary to unlock the back door using the transmitter switch or door control switch on the driver side door or passenger's door before opening the back door.
