Body Control Module (BCM) monitors and supplies an output on White wire from door unlock switch. When BCM receives unlock command from remote control door lock receiver, BCM supplies voltage on White wire to unlock doors. RKE transmitter and/or door locks must be activated to unlock doors. DTC sets when BCM receives unlock signal from remote control door lock receiver module and White wire is shorted to voltage for more than 3 minutes. System voltage must be 9.0-16.0 volts.
