INITIALIZE BACK DOOR POWER WINDOW CONTROL SYSTEM
NOTICE:
Resetting the power window regulator motor (initializing the pulse sensor) is necessary if: 1) the bat-
tery terminal cable is disconnected; 2) the back door ECU, wire harness, power window regulator
switch, power window regulator assembly and power window regulator motor are replaced or re-
moved/installed; or 3) the P/W fuse is replaced or removed. If resetting is not performed, the master
switch assembly will not be able to operate the AUTO operation function, jam protection function and
remote operation function.
(a) Turn the ignition switch ON.
(b) Open the power window halfway by pressing the power window switch.
(c) Fully pull up on the switch until the power window is fully closed and continue to hold the switch for

Remote control mirror switch circuit (w/ Driving position memory)
CIRCUIT DESCRIPTION
The remote control mirror switch has different levels of resistance depending on the switch position.
The body ECU senses the switch position through the resistance of the remote control mirror switch.
The body ECU sends an up/down/right/left signal to the driver door ECU and the passenger door ECU via
BEAN.
The mirror's driving position and retract position are directly controlled by the remote control mirror switch.
