Rear Door UNLOCK Detection Switch LH Circuit: Description
WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
The rear door unlock detection switch LH is built into the rear door lock motor LH. The switch turns on when the rear door LH is unlocked and turns off when the door is locked. The main body ECU is connected to the rear door lock motor LH via terminal LSWL and rear door LH lock/unlock state signals are input to the ECU. The main body ECU applies voltage to the door unlock detection switch via terminal LSWL. When the door unlock detection switch is off (there is continuity between the switch terminals), a lock state signal is input to the ECU. When the switch is on (there is no continuity between the switch terminals), an unlock state signal is input.
