Pinpoint Test O: The Smart Unlock Does Not Operate Correctly

Normal Operation

The Remote Function Actuator (RFA) module commands all doors to unlock to prevent an Intelligent Access (IA) key from being inadvertently locked inside the vehicle. When the vehicle is locked using either door lock control switch with the door ajar and then closed, the RFA module searches the interior of the vehicle for an IA key. The RFA module searches the interior of the vehicle by activating all 3 low frequency antennas. If an IA key is inside the vehicle, the signal from the low frequency antennas activate the IA key, and sends a signal back to the RFA module through the Remote Functions Receiver (RFR) module. If the RFA module detects that there is an IA key inside the vehicle, it unlocks all of the doors and honks the horn.

The vehicle can still be locked with an IA key in the vehicle, by using a key in the door lock cylinder, keyless entry keypad, or the lock button on another IA key.

This pinpoint test is intended to diagnose the following:

- Door ajar switch input
- IA key
- RFA module



PINPOINT TEST O: THE SMART UNLOCK DOES NOT OPERATE CORRECTLY

-------------------------------------------------
O1 CHECK THE COURTESY LAMP OPERATION


- Open and close each door while checking the courtesy lamp operation.
- Do the courtesy lamps operate correctly?

Yes
GO to O2.

O2 CHECK THE IA KEY


- Place the IA key on the instrument panel, center console, and the rear seat.
- Start the engine with the IA key in each location.
- Does the engine start with the key in each location?

Yes
GO to O3.

No
REFER to the symptom chart in Antitheft and Alarm Systems. Symptom Related Diagnostic Procedures

-------------------------------------------------
O3 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 Body Control Systems. 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.
