B3145

DTC B3145 or B3155

Circuit Description

The passenger door lock switch signal circuits provide inputs to the passenger door module (PDM) when the passenger door lock switch is activated to the Lock or Unlock position. These inputs allow the PDM to detect a door Lock or Unlock request. The PDM provides power to the passenger door lock switch. When the door lock switch is activated to the Lock or Unlock position, ground is supplied by G202. When the PDM detects low voltage on a signal circuit, it will send a message on the serial data line to the remote control door lock receiver (RCDLR) to enter the power door latches in Lock or Unlock status. For more detailed information concerning power door lock operation refer to Power Door Locks Description and Operation.
