Pinpoint Test O: The Luggage Compartment/Liftgate Smart Unlock Is Inoperative

Normal Operation

The luggage compartment/liftgate smart unlock feature prevents the luggage compartment/liftgate from latching when an Intelligent Access (IA) key is detected inside the luggage compartment. When the Remote Function Actuator (RFA) module detects the luggage compartment lid/liftgate is closed with the doors locked, it searches the luggage compartment using the low frequency passive start antenna located behind the rear seat for an IA key. If an IA key is inside the luggage compartment the signal from the passive start antenna activates the IA key, and it sends a signal back to the RFA module through the Remote Functions Receiver (RFR) module. If an IA key is detected, the luggage compartment lid/liftgate releases. To override the luggage compartment/liftgate smart unlock and intentionally latch the luggage compartment lid/liftgate, unlock the doors and then close the luggage compartment lid with the IA key inside.

This pinpoint test is intended to diagnose the following:

- Luggage compartment lid/liftgate ajar switch input
- Rear passive start antenna
- IA key
