Pinpoint Test AL: 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 will search 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 will activate the IA key, and it will send 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 will unlock all of the doors and honk 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 AL: THE SMART UNLOCK DOES NOT OPERATE CORRECTLY

-------------------------------------------------
AL1 CHECK THE COURTESY LAMP OPERATION


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

- Does the engine start with the key in each location?

Yes
GO to AL3.

No
REFER to Antitheft and Alarm Systems.

-------------------------------------------------
AL3 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.
