Passive Entry
When the BCM detects the battery state of charge to be below a pre-determined level, the passive entry feature only operates from the driver door.
Doors
With a programmed passive key within 1 m (3.28 ft) outside a door, touch the lock sensor at the bottom of the front door window moulding or activate the exterior door latch release switch. The doors lock or unlock and unlatch depending upon which input the BCM receives.
The driver front door passive entry feature either unlocks the driver door (if 2-stage unlock is enabled) or all four doors (if 2-stage unlock is disabled). The passive entry feature always locks all four doors when the lock sensor is touched for a half second.
The remaining doors passive entry feature always locks or unlocks all four doors.
Liftgate
With a programmed passive key within 1 m (3.28 ft) outside the liftgate, press the liftgate button on the rear of the vehicle to power open the liftgate.
Door Passive Entry
Door Unlock and Unlatch
When the doors latch control modules are in lock mode and the request to unlatch the door is detected from the outside door latch release switch, the door lock control module sends a passive entry unlock request through a circuit monitored by the BCM.
When the BCM detects a passive entry unlock request, it activates the keyless entry door antennas (located aft of the rear wheels between the body and rear bumper cover). The keyless entry door antenna sends out a low frequency signal to the passive key. The low frequency signal activates the passive key and the passive key sends a high frequency signal to the RTM. The RTM interprets the high frequency signal from the passive key and sends the key information to the BCM. If the BCM detects a valid programmed passive key, the BCM either commands the driver door to unlock or all the doors to unlock. The respective door latch control module then releases the door latch.
The passive entry unlock feature does not activate if the doors are in unlock mode.
Door Lock
The passive entry door lock touch sensors (located at the bottom of each front door window moulding) are provided voltage by the BCM at all times. The sensor and the integrated lock LED is monitored and controlled by the respective front door latch control module. When the front door latch control module detects the lock sensor is touched, the door lock control module sends a passive entry lock request through a circuit monitored by the BCM.
When the BCM detects a passive entry lock request, it activates the keyless entry door antennas. The keyless entry door antenna sends out a low frequency signal to the passive key. The low frequency signal activates the passive key and the passive key sends a high frequency signal to the RTM. The RTM interprets the high frequency signal from the passive key and sends the key information to the BCM. If the BCM detects a valid programmed passive key, the BCM commands all the doors to lock.
The passive entry lock feature does not activate if the doors are in lock mode.
The passive entry door lock touch sensors are integrated into the front door upper window mouldings.
Liftgate Passive Entry
When the BCM is in lock mode and the liftgate button is pressed or the liftgate hands free request is detected, it activates the rear keyless entry antenna inside the cargo area. The rear keyless antenna sends out a low frequency signal to the passive key. The low frequency signal activates the passive key and the passive key sends a high frequency signal to the RTM. The RTM interprets the high frequency signal from the passive key and sends the information to the BCM. If the BCM detects a valid programmed passive key, the BCM sends a request to the RGTM to power open the liftgate.
