Title: DOOR LOCK: POWER DOOR LOCK CONTROL SYSTEM: Rear Door UNLOCK Detection Switch RH Circuit;

2015 MY Tundra [08/2014 - ]

Rear Door UNLOCK Detection Switch RH Circuit

DESCRIPTION

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.
