INSPECT REAR DOOR LOCK ASSEMBLY RH (DOUBLE LOCK POSITION SWITCH)

CHECK WIRE HARNESS (REAR DOOR LOCK ASSEMBLY RH - DOUBLE DOOR LOCK ECU)

POWER DOOR LOCK CONTROL SYSTEM - Rear Double Lock Position Switch RH Circuit


DESCRIPTION

The rear right side door double lock position switch is built into the rear right side door lock assembly. The switch turns on when the rear right side door double lock is set and turns off when the double lock is released.
The double door lock ECU is connected to the rear right side door lock assembly via terminal DLPR and rear right side door double lock set/released state signals are input to the ECU.
The double door lock ECU applies voltage to terminal DLSR of the double lock position switch via terminal DLPR. When the switch is on (there is continuity between the switch terminals), a set state signal is input to the ECU. When the switch is off (there is no continuity between the switch terminals), a release state signal is input.
The double door lock ECU sends rear right side door double lock set/released state signal to the main body ECU RH using multiplex communication.
