Rear Door UNLOCK Detection Switch RH 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 RH is built into the rear door lock motor RH. The switch turns on when the rear door RH is unlocked and turns off when the door is locked. The main body ECU is connected to the rear door lock motor RH via terminal LSWR, and rear door RH lock/unlock state signals are input to the ECU. The main body ECU applies voltage to the door unlock detection switch via terminal LSWR. 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.
