Liftgate Intelligent Access (IA)

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The Intelligent Access (IA) feature is a programmable parameter and can be enabled/disabled with a scan tool. If the feature is disabled, the Intelligent Access (IA) feature to enter the vehicle and passive starting will be inoperative. To start the vehicle, the Intelligent Access (IA) key has to be placed in the backup slot.

The liftgate Intelligent Access (IA) feature allows the liftgate to be opened without having to use an interior liftgate switch or a RKE transmitter. With a programmed Intelligent Access (IA) key within 1 m (3.28 ft) outside the liftgate, press the liftgate release button on the liftgate, and the power liftgate opens.

When the RFA module detects a signal from the exterior liftgate switch, it activates the low frequency antenna in the rear bumper cover. The low frequency antenna sends out a signal to the Intelligent Access (IA) key. The low frequency signal activates the Intelligent Access (IA) key and the Intelligent Access (IA) key then sends a high frequency signal back to the TPM module. The TPM module interprets the high frequency signal from the Intelligent Access (IA) key and sends the information to the RFA module. If the RFA module determines that it is a programmed key, it sends a message to the LTM over the MS-CAN . When the LTM receives an open request message, it opens the liftgate.
