Pinpoint Test AK: The Auto-Unlock Does Not Operate Correctly

Normal Operation

The Remote Function Actuator (RFA) module energizes the unlock relay based upon input from the door ajar switches and the vehicle speed signal. The RFA (Remote Function Actuator) module receives the vehicle speed signal and door ajar input from the Body Control Module (BCM) over the Medium Speed Controller Area Network (MS-CAN). The RFA (Remote Function Actuator) module unlocks the doors when the following sequence of conditions is met:

- the vehicle speed has exceeded 20 km/h (12 mph) then dropped to 0 km/h (0 mph)

- the ignition is switched to the OFF or ACC mode

- the LH front door is opened within 10 minutes of the ignition being switched to the OFF or ACC mode

This pinpoint test is intended to diagnose the following:

- Door ajar switch input

- Vehicle speed signal message

- Programming
