When any exterior door handle is lifted, switched ground signals are sent to the keyless entry control module through the door handle switch signal circuits. Upon receipt of these inputs, the keyless entry control module will check the door lock status of the following inputs:

  • Driver door handle is still pulled
  • An unlatch enable signal from the BCM has been received

Once the enable criteria has been met, the keyless entry control module will supply power and ground to door unlatch motor control circuits and the door will release.
