System Description
1. BACK DOOR CLOSER SYSTEM DESCRIPTION
(a) Operating any power back door switch when the back door is fully closed inputs a request signal to the power back door ECU*1 or back door closer ECU*2. The power back door ECU*1 or back door closer ECU*2 outputs a "latch release" command to the back door lock in response to the input.
(b) The latch can be released only when the back door is unlocked.
(c) 3 switches are built into the back door lock, and the power back door ECU*1 or back door closer ECU*2 monitors each switch status. The power back door ECU*1 or back door closer ECU*2 controls latch "release/ close" operations in response to the inputs from each switch.
