Power Door Latch Unlatch Operation

The keyless entry control module will detect the keyless entry transmitter and when an exterior door handle is pulled and the transmitter is within 1 meter (3 feet) of the door handle, the body control module (BCM) will unlock the doors and send the unlatch enable signal to keyless entry control module. 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 system as described above. Once the enable criteria has been met, the keyless entry control module will supply power and ground to door latch control circuits and the door will release.
