Driver/Passenger Door Intelligent Access (IA) Feature

NOTE: The 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 IA key has to be placed in the backup slot. Refer to MODULE CONFIGURATION for information on enabling/disabling the IA feature.

The driver/passenger door IA feature allows the doors to be locked or unlocked without having to use the door lock cylinder, keyless entry keypad or the RKE transmitter. With a programmed IA key within 1 m (3 ft) of either front door handle outside of the door, touch the lock or unlock sensor on the exterior door handle and, depending upon which sensor was touched, the doors either lock or unlock. The IA feature from the driver door only unlocks the driver door (with stepped unlock enabled) and the IA feature from the passenger door unlocks all four doors. The IA feature from either front door locks all four doors.

When the RFA module detects that a lock or unlock sensor is touched on a front exterior door handle, it activates the low frequency antenna in the corresponding exterior front door handle. The low frequency antenna sends out a signal to the IA key. The low frequency signal activates the IA key and the IA key then sends a high frequency signal back to the TPM module. The TPM module interprets the high frequency signal from the IA key and sends the information to the RFA module. If the RFA module determines that it is a programmed key, it either unlocks the driver door, unlocks all 4 doors, or locks all 4 doors.
