| Title: DOOR / HATCH: BACK DOOR CLOSER SYSTEM: SYSTEM DESCRIPTION (2008 Sequoia) | ||
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. The power back door ECU then 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 monitors each switch status. The power back door ECU controls latch "release/ close" operations in response to the inputs from each switch.
