Power Back Door Closer Switch Circuit

Power Back Door Closer Switch Circuit

DESCRIPTION
The power back door closer switch only turns on while the switch is being pressed, and turns off when the switch is released.

The power back door ECU is connected to the power back door closer switch via terminal BDDN and power back door operation request signals are input to the ECU.

The power back door ECU applies voltage to the power back door closer switch via terminal BDDN. When the switch is on (there is continuity between the switch terminals), a power back door close request signal is input to the power back door ECU to close the back door.

NOTICE: The power back door ECU records the back door positions in the memory. In the case where any of the batteries, fuses, power back door ECU and power back door drive unit are removed and then reinstalled, the power back door ECU loses the memory of the door positions. In such a case, resetting the power back door system is necessary. Refer to the resetting operation specified.
