System Description

  1. BACK DOOR CLOSER SYSTEM DESCRIPTION 
    1. 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.
    2. The latch can be released only when the back door is unlocked.
    3. 3 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.
