Driver Side Door Unlock Detection Switch Circuit

Driver Side Door UNLOCK Detection Switch Circuit

DESCRIPTION
The driver side door unlock detection switch is built into the front driver's door lock motor. The switch turns on when the driver's door is unlocked and turns off when the door is locked. The main body ECU is connected to the front driver's door lock motor via terminal LSWD and driver's door lock/unlock state signals are input to the main body ECU. The main body ECU applies voltage to the door unlock detection switch via terminal LSWD. When the door unlock detection switch is off (there is continuity between the switch terminals), a lock state signal is input to the main body ECU. When the switch is on (there is no continuity between the switch terminals), an unlock state signal is input.
