Normal Operation

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

During each vehicle start sequence, when the start/stop button is pressed, the Remote Function Actuator (RFA) module activates all 3 passive start antennas, which send out a low frequency signal. Each passive start antenna has an approximate range of 1 m (3 ft) and are placed in different locations to provide full coverage inside the vehicle. The front antenna is mounted to the front underside of the center console, the center antenna is mounted to the underside of the center console near the back of the front seats, and the rear antenna is mounted next to the liftgate striker. If an Intelligent Access (IA) key is within range of a passive start antenna, the low frequency signal activates the IA  key. When the IA key is activated it sends a high frequency signal to the Tire Pressure Monitor (TPM) module. The TPM  module communicates with the RFA  module. If the RFA  module determines that a programmed IA  key is in the vehicle, it allows the ignition to transition out of off or lets the engine start.

There are certain areas inside the vehicle where the IA  key may not be detected and the message center displays NO KEY DETECTED. If the IA  key is in the far outside edges of the interior (like in a door map pocket or above a sun visor) it might not be detected. Move the IA  key to a different location and try to start the vehicle again.

NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a Passive Anti-Theft System (PATS) no-start if the IA  key is within a few inches of the charger. If a concern is observed, move the IA  key away from the charger and attempt to start the vehicle.

This pinpoint test is intended to diagnose the following:
