Passive Entry (if equipped): Notes

NOTE: To perform an accurate diagnosis of a concern, make sure the vehicle has a fully charged 12V battery and is in good condition when performing any electrical pinpoint tests. When the vehicle's 12-volt battery is below a set threshold, certain features can be limited or become inoperative and lead to misdiagnosis.

The passive entry feature unlocks or locks the doors or opens the liftgate without having to use a mechanical key blade or the RKE transmitter feature.

When the BCM detects a lock or unlock sensor is touched on an exterior door handle, or the exterior liftgate release button is pressed, it activates the low frequency antenna in the corresponding exterior door handle or inside the luggage compartment area. The low frequency antenna sends out a signal to activate the passive key. The passive key then responds by sending a high frequency signal back to the RTM (remote start vehicles). The RTM (remote start vehicles) 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 unlocks the driver door, unlocks or locks all 4 doors, releases the liftgate latch (manual liftgate) or sends a command to the RGTM to power open the liftgate (power liftgate). The BCM (non-remote start vehicles) interprets the ultra-high frequency signal from the passive key via its internal receiver. It then processes that information internally and unlocks the driver door, unlocks or locks all 4 doors, releases the liftgate latch (manual liftgate) or sends a command to the RGTM to power open the liftgate (power liftgate).
