Main Switch Circuit

Main Switch Circuit

DESCRIPTION
The power back door main 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 main switch via terminals MSW and MSE, and power back door operation cancel request signals are input to the ECU.
The power back door ECU applies voltage to the power back door main switch via terminal MSW. When the switch is on (there is continuity between the switch terminals), a power back door operation cancel request signal is input to the power back door ECU.

NOTE: 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.
