Pinpoint Test Q: The Luggage Compartment Smart Unlock Does Not Operate Correctly
Normal Operation
The luggage compartment smart unlock feature prevents the luggage compartment 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 is closed with the perimeter alarm in an armed state, it will search the luggage compartment using the low frequency antenna located underneath the rear seat for an IA key. If an IA key is inside the luggage compartment the signal from the low frequency antenna will activate the IA key, and it will send a signal back to the RFA module through the Remote Functions Receiver (RFR) module. If an IA key is detected, the luggage compartment lid will release and the horn will chirp. To override the luggage compartment smart unlock and intentionally latch the luggage compartment lid, disarm the perimeter alarm by pressing unlock on an IA key, and then close the luggage compartment lid with the IA key inside. Once the luggage compartment lid is closed, rearm the perimeter alarm by pressing 7/8 and 9/0 on the keyless entry keypad.
This pinpoint test is intended to diagnose the following:
- Luggage compartment lid ajar switch input
- IA key
- RFA module
PINPOINT TEST Q: THE LUGGAGE COMPARTMENT SMART UNLOCK DOES NOT OPERATE CORRECTLY
-------------------------------------------------
Q1 CHECK THE LUGGAGE COMPARTMENT AJAR MESSAGE IN THE MESSAGE CENTER
- Observe the message center while opening and closing the luggage compartment lid.

No
REFER to Anti-Theft - Passive Anti-Theft System (PATS) Testing and Inspection.
-------------------------------------------------
Q3 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect all the RFA module connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the RFA module connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes
INSTALL a new RFA module. REFER to Multifunction Electronic Modules Remote Function Actuator (RFA) Module. TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
